Throughout this Form ATS-N the Broker-Dealer Operator, CODA Markets, Inc., is referred to as "CODA Markets" and the NMS Stock ATS is referred to as "CODA". As disclosed in CODA Markets' disclosure document which is distributed, at a minimum, annually to Subscribers, CODA Markets has a payment for order flow arrangement in the form of a profit-sharing agreement with ACS Execution Services LLC ("ACS") that in some instances executes trades on a net basis. CODA Markets receives a portion of the profits that ACS earns with respect to the order flow sent by CODA FLARE ("FLARE") to ACS. FLARE is CODA's outbound router discussed throughout this Form and in detail in Part III, Item 16(b). ACS is also a Subscriber to CODA and may send orders to CODA for execution through FLARE. CODA Markets and ACS do not have a preferential routing arrangement, and CODA Markets and ACS are under no obligation to send any orders to each other. Any orders that are sent to CODA by ACS that are seeking liquidity for orders routed to ACS by FLARE are not eligible for trading in CODA. If executed by CODA Markets, such orders are executed exclusively through FLARE pursuant to ACS's FLARE routing strategy at away markets. Additionally, CODA Markets is a subscriber to or participant via FLARE of Trading Centers operated by a number of its other Subscribers. These arrangements are subject to per executed share fee schedules that may include rebates, charges or be free of charge for and paid by the Subscriber when trading on CODA, or for and paid by CODA Markets when executing via FLARE at the away Trading Center. In all cases, neither CODA Markets nor the Subscribers that operate these other Trading Centers are under any obligation to send orders to CODA or the Subscribers' Trading Center. To the extent that such Subscribers participate in CODA, these Subscribers do not receive preferential treatment. 

CODA PULSE ("PULSE") is a downloadable application available to CODA Markets Subscribers and Sponsored Users, referred to collectively in this Form as "Participants".

CODA Markets, the Broker Dealer Operator of CODA (the Reg NMS Stock ATS), requires broker-dealers and institutions accessing CODA in their own MPID (broker of record) or in their own name (institutional), to complete and execute certain documents, including a Subscriber Agreement, as part of CODA Markets onboarding and approval process. Firms accessing and trading at CODA in this manner are referred to as "Subscribers" in this Form. "Sponsored Users" are defined as firms who access and trade with CODA via an approved risk gateway of a sponsoring broker Subscriber. In all cases, the sponsoring broker is a CODA Subscriber and the broker of record on all orders, conditional interests and "firm up" orders received from and on trades with the Sponsored User. CODA Markets requires each Subscriber to be reviewed and approved by a Principal of CODA Markets before accessing the ATS services. Prior to that approval, CODA Markets, as part of its onboarding process, works with new Subscribers to build an understanding of their order flow profile and expected usage of the platform. In addition to a review of the Subscriber Agreement and accompanying paperwork for completeness, CODA Markets' Chief Compliance and AML Officer performs a screening of each new Subscriber, its associated persons and direct and indirect owners. New Subscribers are screened for solvency, regulatory disclosures, lines of business, key personnel, AML, sanctions, anti-corruption and negative news. In conjunction with the screening, CODA Markets Compliance will access information provided by the Subscriber, such as size of the firm, assets under management, type of orders, e.g., retail, institutional, types of securities to be traded, expected average per order share size, per order notional, number of orders per day, and frequency of orders for the purpose of establishing risk management control settings as required under SEC rule 240.15c3-5 (additional information can be found in Part III, Item 8(a)). A Subscriber will be denied access to the ATS services for having no Rule 15c3-5 market access checks, significant regulatory disciplinary actions, anti-money laundering violations, financial instability that if otherwise approved, could cause a disruption to the ATS services or its Participants. Subscribers that are not registered broker-dealers are required to have $50 million or more in assets under management and a qualifying prime brokerage or custodial agreement to be approved to access the ATS services. CODA Markets' Subscriber Agreements require unique attestations for Broker-Dealer Subscribers and Institutional Subscribers as appropriate for each firm type. 

CODA Markets maintains the right to exclude, at its discretion, Participants from using any feature of the ATS including access to CODA, use of specific auction and order types, acting in the capacity of a Liquidity Seeker or Liquidity Provider, entering or interacting with conditional interests, access to Request-for-Trade "(RFT")/Auction Alert feeds and use of the router. CODA Markets reserves the right to modify this list at any time. Examples of why CODA Markets may choose to exclude a Participant include, but are not limited to the following: - CODA Markets determines a Participant's usage of the system to be a risk to the CODA systems and/or other Participants. - A Participant's firm up rate to conditional invites falls below expected levels (as further described in Part III, Item 9). - A Participant receiving RFTs or Auction Alerts (via FIX, OMS/EMS, PULSE) shows no intent to participate (as further described in Part 3, Item 9). - A Subscriber loses their FINRA (or other SRO) membership. 

CODA executes trades in the capacity of a NMS Stock ATS between the hours of 9:30:00 A.M. ET and 4:00:00 P.M. ET. The CODA BLOCK auction type does not allow initiation of a new auction after 3:59:00 P.M. ET. CODA accepts orders and conditional interests as early as 6:00:00 A.M. ET. At a Subscribers' discretion, orders received prior to 9:30:00 A.M. ET may be accepted and held by CODA until 9:30:00 A.M. ET. At that time, the orders become eligible for execution. Alternatively, Subscribers wishing to execute their orders between 6:00:00 A.M. ET and 9:30:00 A.M. ET may instruct CODA to route orders to away trading centers where orders are eligible for "pre-market" execution. At 4:00:00 P.M. ET, all orders and conditional interests are cancelled at CODA. Subscribers utilizing CODA's outbound router, FLARE, and wishing to trade in the "post-market" may have unexecuted orders routed to away trading centers where orders are eligible for "post-market" execution. At the Subscribers' discretion CODA accepts and routes orders eligible for "post-market execution" between 4:00:00 P.M. ET and 5:00:00 P.M. ET. At 5:00:00 P.M. ET all open orders are cancelled. 

CODA requires all orders and conditional interests to be entered via Financial Information eXchange ("FIX") protocol. CODA supports both FIX 4.2 and 4.4. 

CODA Markets does not provide any hosting, cabinet space or equipment to Participants of its NMS Stock ATS. CODA offers several cross connect options at two data center co-location facilities where CODA's systems reside. Cross connects can be intra-datacenter (cage-to-cage). CODA Markets' networking, sales and operations team discuss cross connect and related services with Participants wanting to connect via cross connect. Each configuration is agreed to in advance. A Letter of Authorization ("LOA") is provided to the firm ordering the cross connect. The LOA is provided to the data center as part of the cross connect order request. Standard options for cross connects are based on available cross connect options provided by the datacenter co-location facility and currently supported/owned CODA equipment located at the co-location facility. Cross connect options available at NY5, located at 800 Secaucus Road, Secaucus, New Jersey 07094, and supported by CODA systems include the following (Connection Service; Media Type; Protocol Type; Connection Type; Speed): - Single-Mode Fiber; Single-Mode Fiber; 10 GIG ETHERNET; Fiber; 10 GbE - Single-Mode Fiber; Single-Mode Fiber; GIGABIT ETHERNET; Fiber; 1 GbE - Multi-Mode Fiber; 50 MICRON MULTI-MODE FIBER OM3; 10 GIG ETHERNET; Fiber; 10 GbE - Multi-Mode Fiber; 50 MICRON MULTI-MODE FIBER OM3; GIGABIT ETHERNET; Fiber; 1 GbE - Multi-Mode Fiber; 62.5 MICRON MULTI-MODE FIBER; GIGABIT ETHERNET; Fiber; 1 GbE - UTP; CAT6; FAST ETHERNET; Copper; 100 Mbs - UTP; CAT6; GIGABIT ETHERNET; Copper; 1000 Mbs - UTP; CAT6; ETHERNET; Copper; 10 Mbs UTP; CAT5e; FAST ETHERNET; Copper; 100 Mbs - UTP; CAT5e; GIGABIT ETHERNET; Copper; 1000 Mbs - UTP; CAT5e; ETHERNET; Copper; 10 Mbs Cross connect options available at NJ2 located at 300 Blvd East, Weehawken, NJ 07086, and supported by CODA's systems include the following (Cross Connect Type; Protocol Type; Connection Type; Speed): - Fiber Cross Connect; 10 GIG Single-Mode Fiber; Fiber; 10 GbE - Fiber Cross Connect; GIGABIT Single-Mode Fiber ; Fiber; 1 GbE - Fiber Cross Connect; 10 GIG Multi-Mode Fiber; Fiber; 10 GbE - Fiber Cross Connect; GIGABIT Multi-Mode Fiber; Fiber; 1 GbE - Copper Cross Connect; FAST ETHERNET; Copper; 100 Mbs - Copper Cross Connect; GIGABIT ETHERNET; Copper; 1000 Mbs - Copper Cross Connect; ETHERNET; Copper; 10 Mbs The terms, conditions and available cross connect options provided above are the same for all Subscribers and the Broker-Dealer Operator. As shown, certain options available in one co-location facility may not be supported by another co-location facility. Additionally, Subscribers' systems may not support or be compatible with all available options. It is for these reasons that CODA offers multiple options and works closely with Participants while adding new or modifying existing connectivity. 

CODA operates on an on-demand order-initiated, auction-based market structure offering two Auction Types, CODA MICRO and CODA BLOCK. Each Auction Type supports certain order types and may handle order types differently based on the Auction Type and capacity ("Liquidity Seeker" vs. "Liquidity Provider") in which an order is interacting on the ATS. "Liquidity Seeker" orders participate on CODA by: - Initiating on-demand auctions; - Resting orders (firm and/or conditional) to participate in future auctions initiated by other Liquidity Seeker orders; and - Using CODA's outbound order router, FLARE. "Liquidity Provider" orders participate on CODA by: - Responding with orders to on-demand auctions initiated by Liquidity Seeker orders CODA MICRO accepts and handles the following order types from Liquidity Seekers: - Limit - Market - Pegged (midpoint, primary, market). Peg Offset is allowed for primary and market pegged orders and discussed in detail in this item below. - Managed - Managed Orders reside in CODA's Managed Order Facility ("MOF") and allow Liquidity Seekers to interact with and execute against order flow from other Liquidity Seekers. CODA automatically generates Immediate-or-Cancel ("IOC") responses based on the detail of the Managed order and on behalf of the Liquidity Seeker if the Managed order provides executable contra-side liquidity to any of the auction types or matching protocols discussed in this document. Managed Orders do not have priority over Liquidity Provider responses. At CODA's discretion, Managed Orders can be deemed ineligible to interact with certain auctions. For example, a Subscriber's negotiated fee for initiating and executing in CODA MICRO may be a rebate higher than the average negotiated fee charged to other Subscribers for resting Managed Orders in the MOF (see detail on Fees in Part III, Item 19). As a result, CODA Markets would be expected to pay a rebate to the initiating Subscriber that is of a greater amount than what it charged to the Subscriber resting in the MOF. Since CODA Markets would lose money on the trade, this is an example of why Managed Orders can be deemed ineligible for interaction in an initiating Subscriber's CODA MICRO auctions. Managed Orders on the same side in the same symbol are given price / time priority over each other unless otherwise specified (see description of CODA BLOCK auctions in Part III, Item 11 (c)). In other words, in CODA MICRO, if two Managed Orders have the same price and are on the same side, then the Managed Order with the earlier time stamp of receipt can trade against the initiating order, up to the Managed order's quantity, before the Managed order with the later time stamp is given an opportunity to trade with any residual quantity. - Conditional - Conditional interests and "firm up" orders are a type of Managed Order, do not initiate auctions and allow Liquidity Seekers to provide liquidity to auctions initiated by other liquidity-seeking orders. In CODA MICRO auctions, conditional interests and 'firm up" orders are deemed a supplemental liquidity source and only trade with residual shares of an auction-initiating order once the auction is complete. At that time, if an eligible CODA MICRO initiating order is executable against a contra conditional interest then the conditional interest is invited to firm up. Conditional interests may be entered as Market, Limit or Pegged. A conditional interest must be replaced with a firm (Market, Limit or Pegged) order prior to execution. The process of replacing conditional interests with firm orders, known as a "firm up," introduces latency to the execution process. As such, Liquidity Seekers may opt out of interacting with conditional interests and "firm up" orders. Additionally, CODA can opt out certain CODA FLARE-eligible orders of interacting with conditional interests as needed to achieve the execution goals of the specific FLARE strategy and to optimize performance. For example, the performance of certain FLARE strategies could be negatively impacted by the latency of the "firm up" process. CODA can peg Conditional interests to the midpoint of the NBBO by default at the request of the Liquidity Seeker. CODA BLOCK accepts and handles the following Order Types from Liquidity Seekers: - Limit Orders - Pegged Orders - Market, primary and midpoint pegged orders are all accepted and are handled the same as pegged orders in CODA MICRO. - Managed Orders - Managed Orders greater than 1,000 shares and residing in the MOF are eligible to interact with CODA BLOCK auctions. Managed Orders are reserved as participating orders in a CODA BLOCK auction during the Phase 3 Auction Alert (see description of CODA BLOCK in Part III, Item 11 (c)). - Conditional - Conditional interests and "firm up orders" can only participate (not initiate) in CODA BLOCK auctions. Conditional interest invites will include an indication that the invite is for a CODA BLOCK auction. CODA BLOCK auction conditional interest invites will be sent to all eligible conditional interests in that symbol regardless of side, size and price of the initiating order. The CODA BLOCK invite does not indicate the explicit side, size or price of the initiating order, but instead echoes the information from the conditional interest of the Subscriber receiving the invite. Therefore, the CODA BLOCK invite is deemed to be symbol-only in nature. As with all participating orders, "firm up" orders submitted to a CODA BLOCK auction must be at least 1,000 shares to be eligible. "Firm up" orders must be Limit or Pegged Orders (Market orders will be rejected). Conditional interests whose "firm up" orders are submitted to a CODA BLOCK auction are treated with the same priorities and on the same basis as other participating orders. Due to the multilateral (potential for more than two counterparties to participate in a single auction with one print to the tape) matching rules of CODA BLOCK (discussed in detail in Part III, Item 11 (c)), conditional interests and their subsequent "firm up" orders may not participate in the allocation process due to their limit price, minimum fill quantity or other order instructions even following receipt of an invite. As a result of the symbol-only nature of the CODA BLOCK conditional interest invite, Subscribers may choose to not submit a "firm up" order. Any unfilled shares on a "firm up" order will be cancelled back to the Subscriber at the completion of the auction. CODA MICRO and CODA BLOCK accept and handle Liquidity Provider orders as follows: - All CODA auction types and matching protocols allow Liquidity Providers to generate firm IOC orders in response to liquidity-seeking order flow. When responding to CODA MICRO "price improvement auctions" and CODA BLOCK RFT/Auction Alerts, the Liquidity Provider responses remain tagged as IOC; however, they are paused for the full length of the auction in order for CODA to identify and complete the price discovery process (discussed in detail in Part III, Item 11 (c)). - Liquidity Providers may send Pegged Orders (midpoint, market, primary). Peg Offset is allowed for primary and market pegged orders and discussed in detail later in this section. - Liquidity Providers may send orders with discretion offset to provide additional price improvement to their orders. Discretion offset values may be no smaller than $0.01. - At the completion of any CODA auction, unfilled Liquidity Provider responses are cancelled. Liquidity Providers may only enter orders when responding to an RFT/Auction Alert. All Liquidity Provider orders are treated as IOC and are not eligible for routing via FLARE. If Liquidity Providers send Day orders they will be treated as IOC as described above. Priority is determined by the matching engine logic and rules of engagement of each Auction Type as discussed in Part III, Item 11. Any conditions affecting rank and/or price for execution are defined throughout this Item and in the Auction Type descriptions detailed in Part III, Item 11(c). Orders tagged for and directed to CODA BLOCK are only eligible to participate in CODA BLOCK auctions. Day orders tagged for and directed to CODA MICRO are eligible to participate in CODA BLOCK auctions while resting in MOF and of at least 1000 shares. Managed and Conditional interests are defined as liquidity-providing order types. As a result, Liquidity Seekers using these order types may award price improvement to the contra side counterparty. For purposes of this filing, CODA will refer to "remove liquidity" as initiating an auction and "adding liquidity/post-only orders" as participating in auctions/responding orders. An auction must be initiated for an order, regardless of its marketability, to interact with resting liquidity at CODA. Subscribers wishing to trade on CODA strictly by participating in auctions initiated by other Subscribers may do so via the following means: 1) Participate via the Liquidity Provider FIX Specification 2) Nonmarketable orders by rule do not initiate auctions. Liquidity Seekers sending orders that are nonmarketable, defined by default as buy orders with a limit price less than or equal to NBB or sell orders with a limit price greater than or equal to NBO at the time of receipt, will not initiate auctions. Subscribers may also request to treat orders priced greater than NBB and less than NBO as nonmarketable. Based on Subscriber preference, nonmarketable Day orders may rest in the Managed Order Facility to participate in future auctions or cancel back to the Subscriber. 3) Conditional interests and "firm up" orders, by rule, do not initiate auctions; therefore, conditional interests and their corresponding "firm up" orders will only participate in auctions initiated by other Subscribers. 4) Request a participate only (post-only) configuration. In this case, FIX tags are used on an order-by-order basis as order handling instructions for CODA. 5) Subscribers may instruct CODA to handle an order as a Managed Order via a custom time-in-force value (Tag 59 = A). As previously discussed, CODA supports pegged orders from both Liquidity Seekers and Liquidity Providers. The supported pegged order types or execution instructions are: - MIDPOINT - Midpoint pegged orders allow the Liquidity Seeker to use any of the auction types or matching protocols to source liquidity at the midpoint of the NBBO or better ("Midpoint Order"). CODA identifies an order as a Midpoint Order in each RFT/Auction Alert sent to the Liquidity Providers (except in CODA BLOCK auctions). When responding to auctions, a Liquidity Provider can send a Midpoint Pegged Order in response. Using both CODA's market data feed and the limit prices (if present) on the Subscribers' orders, CODA matches the Liquidity Seeker and Liquidity Provider(s) at the midpoint of the NBBO and prints to the TRF. - MARKET - Market pegged orders allow Subscribers to instruct CODA to execute its order at the current market price. Market pegged orders maintain a limit price equal to the NBO for buy orders and a limit price equal to the NBB for sell/sell short orders. - PRIMARY - Primary pegged orders allow the Subscribers to instruct CODA to execute its order at a limit price that is relative to the NBBO. Primary pegged orders maintain a limit price equal to the NBB for buy orders and a limit price equal to the NBO for sell/sell short orders. Liquidity Seeker primary pegged orders do not initiate auctions but instead they rest, eligible to participate in future auctions. CODA supports peg offset instructions from both Liquidity Seekers and Liquidity Providers. Subscribers may add offset (at a value no less than $0.01 for stocks priced above $1.00) to market and primary pegged order instructions. This will maintain a limit price above or below the NBBO equal to offset value. Peg offset is supported on Primary and Market pegs only. To provide price improvement to Liquidity Seekers via limit orders, Liquidity Providers can populate an additional FIX tag (discretion offset) in their response. This tag will identify the amount (numeric value) to which they are willing to provide price improvement beyond their limit price. When CODA matches a Liquidity Provider's order indicating a willingness to provide price improvement against a liquidity-seeking order, CODA's matching logic adds the value in that FIX tag to the limit price on the Liquidity Provider's order to calculate the final price for the trade. Liquidity Providers may provide price improvement instructions to limit orders based on their limit price (discretion offset) as well as offset to pegged orders based on the NBBO (peg offset). Except for trading in stocks priced below $1.00, CODA does not accept orders with sub-penny values in the price tag; however, midpoint executions may occur at sub-penny values. Liquidity Seekers may instruct CODA to default orders to a midpoint pegged order type. Pegged order types do not require a limit price, but pegged orders without a limit price will not initiate auctions. Pegged orders are treated the same as non-pegged orders in terms of priority. CODA does not adjust limit prices or peg type based on NBBO or other market conditions. Liquidity Providers' orders are not eligible for routing to other Trading Centers. Liquidity Seekers' instruct CODA to route orders to other Trading Centers via FIX tags and as discussed with the Subscriber (verbally, in writing or both) during the onboarding process and ongoing support conversations. Both Day and IOC orders can be eligible for outbound routing. Custom time-in-force values (Tag 59 = 9, Tag 59 = B and 59 = A) in addition to the standard values for Day and IOC orders (Tag 59 = 0 and Tag 59 = 3) are supported by CODA. The custom TIF values instruct CODA to either route or not route orders on an order-by-order basis. Subscribers interested in using custom TIF values can request information from CODA at any time. CODA MICRO and CODA BLOCK allow time-in-force instructions of Day and IOC. A Day order is an order that automatically expires if it is not executed before the end of the trading day on which the order was entered. Subscribers can cancel Day orders at their discretion during the trading day. An IOC order is an order that executes all or part immediately and automatically cancels any unfilled portion of the order. CODA handles IOC orders as follows: Auction-initiating orders with time-in-force instructions of IOC survive for the length of the auction unless successfully cancelled by the Subscriber before the end of the auction. Responding orders to CODA MICRO (Price Improvement Auction) and CODA BLOCK with time-in-force instructions of IOC survive for the length of the auction unless successfully cancelled by the Subscriber. Liquidity Provider orders are all treated as IOC. Time-in-force instructions of Day from Liquidity Provider orders will be accepted, but the order will still be treated as IOC. All orders types can be modified to update price, quantity, order type (limit to market, or vice versa) and side (sell to sell short, or vice versa). Other modifications are not allowed. CODA BLOCK orders modified to reduce quantity will be rejected if the reduced quantity violates CODA BLOCK initiating or participation requirements. All order types can be replaced with the allowed modifications identified above. All order types can be cancelled at any time by the Subscriber including during a CODA auction, after a CODA auction, while an order is routing out via FLARE and while an order is resting at CODA or an away trading center. CODA will process cancel requests immediately upon receipt, but executions may occur before the cancel request is fully processed. Order types may be rejected for several reasons including a violation of CODA's FIX specifications, Subscribers' risk limits (discussed in Part III, Item 2) or the product requirements of CODA's two Auction types (discussed in detail in Part III, Item 11(c). An order for one auction type cannot by modified or replaced to a different auction type. Availability of order types is not determined by form of physical connectivity to CODA ATS. FIX sessions are, however, configured as either Liquidity Seeker or Liquidity Provider, not both. Subscribers wishing to act in the capacity of both a Liquidity Seeker and Liquidity Provider must do so over unique FIX sessions. Subscribers using third party OMS/EMS vendors or algorithms to enter orders to CODA ATS may be limited with respect to entering orders into CODA based on the limitations of the third-party provider. For example, one EMS vendor may offer its clients pegging functionality while another EMS vendor does not. 

CODA enforces a maximum per order quantity and notional value as part of its inbound order risk checks and 15c3-5 obligations. CODA MICRO: There are no minimum or maximum order quantities based on rules of the matching engine for orders entered in the capacity of a Liquidity Seeker. CODA enforces a minimum order quantity of 100 shares on orders entered by Subscribers in the capacity of a Liquidity Provider. There is no maximum quantity for Liquidity Providers other than the aforementioned 15c3-5 risk limit. CODA BLOCK: To initiate CODA BLOCK Liquidity Seekers are required to send a minimum order quantity based on the market capitalization or price of the symbol. The minimum order quantity requirements to initiate CODA BLOCK are as follows: - Small Cap. (market cap. less than or equal to $2B) = 2,000 - Mid Cap (market cap. greater than $2B and less than or equal to $10B) = 5,000 - Large Cap (market cap. greater than $10B) = 10,000 - High-Price (stock price greater than or equal to $100.00/share) = 2,000 To respond to a CODA BLOCK auction, Liquidity Seekers and Liquidity Providers are required to send a minimum quantity of 1000 shares. The 1000 share minimum also applies to resting orders, both firm and conditional, in the Managed Order Facility. Resting orders under 1000 shares are deemed ineligible to participate in a CODA BLOCK auction. There are no maximum quantity rules in CODA BLOCK other than the aforementioned 15c3-5 risk limit. 

CODA MICRO accepts odd-lot orders from Liquidity Seekers, but Liquidity Providers are required to respond with a minimum of 100 shares. CODA MICRO allows for odd-lot executions. Odd-lots are not allowed or eligible to participate in CODA BLOCK. 

The CODA MICRO auction type accepts and processes mixed-lot orders and may execute and print mixed lot trades. The CODA BLOCK auction type accepts mixed lot orders, but rounds mixed lots down to the nearest round lot for processing. The odd lot portion of a mixed lot order tagged for CODA BLOCK is cancelled back to the Subscriber following a trade if the residual quantity is less than 1000 shares. 

Request-for-Trade / Auction Alerts: CODA MICRO and CODA BLOCK, utilize the on-demand, order-initiated auction market structure. CODA sends "symbol-only" notifications, referred to as Request-for-Trades ("RFT") or Auction Alerts, to other Participants (both Liquidity Providers and other Liquidity Seekers depending on the Auction Type). Additionally and contemporaneously with the RFTs/Auction Alerts sent to Liquidity Provider Participants, RFTs/Auction Alerts are sent to CODA's MOF that holds and responds on behalf of resting orders and conditional interests from Liquidity Seekers. The RFT/Auction Alert process serves as the auction call and is used to attract liquidity from other Subscribers that will potentially trade with the initiating liquidity-seeking order. RFT/Auction Alerts may be sent via FIX, PULSE or third-party vendors such as Bloomberg and various OMS/EMS platforms. The RFT/Auction Alert may be in the form of an IOI FIX message type. IOIs typically contain symbol, side, size and price; however, as previously mentioned, RFTs/Auction Alerts are "symbol-only". For that reason, CODA does not refer to RFTs/Auction Alerts as IOIs other than during FIX messaging discussions. For detailed information regarding RFTs/Auction Alerts, including what information can be found in a RFT/Auction Alert, please refer to Part III, Item 11 (a) and (c). Conditional Interests: Conditional interests allow Liquidity Seekers to express interest to provide liquidity to on-demand auctions. Conditional interests reside in the MOF. Subscribers can tag conditional interests to receive invites to firm up from CODA MICRO, CODA BLOCK or both auction types. The invite type (based on auction type) is identified in a FIX tag. Subscribers can tag conditional interests as market, limit or pegged orders. Following an invite, a Subscriber must send a firm up order to the invite within approximately 300 milliseconds to be eligible for execution. The order type, quantity and price on the firm up may be modified from the conditional interest, but they must comply with the auction types' standard rules of engagement. CODA can peg conditional interests and corresponding "firm up" orders to the midpoint of the NBBO by default at the request of the Liquidity Seeker. - In CODA MICRO, conditional interests are deemed a supplemental liquidity source and only trade with residual shares from an auction-initiating order once the auction is complete. Conditional interests showing an executable contra side interest are invited to firm up at that time, based on price/time priority, in sequential order. The information in the invite echoes the symbol, side and price from the invited conditional interest. The size on the invite reflects the requested quantity to be firmed up, which may be less than or equal to the quantity on the invited conditional interest, based on the quantity of residual shares from the CODA MICRO initiating order. The process of replacing conditional interests with firm orders, known as a "firm up," introduces latency to the execution process. As such, conditional interests may not be eligible to interact with some liquidity-seeking orders. For example, a Liquidity Seeker may request (opt out) that their CODA MICRO initiating orders do not interact with conditional interests and firm up orders because they do not want to wait up to 300 milliseconds for the conditional Participant to respond with a firm up order. The Liquidity Seeker order is not eligible for interacting with other orders in CODA while CODA waits for the "firm up" order following an invite. Additionally, a latency sensitive FLARE routing strategy may be less effective if subjected to the additional pause of up to 300 milliseconds during the "firm up" process following the initial CODA MICRO pause as detailed in Part III, Item 11 (c). Participants using conditional interests in CODA MICRO are expected to maintain a firm up rate over 90%. CODA Markets monitors daily and monthly firm up rates across all Participants. Unless CODA is aware of a known reason for a monthly firm up rate less than 90% for the previous month, CODA will contact the conditional Participant and request an explanation. CODA will work with the Participant (i.e., additional testing, review of examples, etc.) to improve the firm up rate. If the conditional Participant fails to improve their firm up rate, CODA reserves the right to disable the Participant's usage of conditional interests as discussed in Part III, Item 3(a). - CODA BLOCK auction conditional interest invites will be sent to all eligible conditional interests in that symbol regardless of side, size and price of the initiating order. Eligible conditional interests for CODA BLOCK are conditional interests of at least 1000 shares. Additionally, Participants can tag conditional interests to opt out of receiving CODA BLOCK invites. The information on the invite echoes the order detail (symbol, side, size, price) from the conditional interest. Conditional interests whose "firm up" orders are submitted to a CODA BLOCK auction are treated with the same priorities and on the same basis as other participating orders. Following receipt of a CODA BLOCK invite, due to the multilateral matching rules of CODA BLOCK (discussed in detail in Part III, Item 11 (c)), conditional interests and their subsequent "firm up" orders may not participate in the allocation process due to the terms and conditions of the firm up order, such as limit price, minimum fill quantity or other order instructions. As a result of the symbol-only nature of the CODA BLOCK conditional interest invite, Subscribers may choose to not submit a "firm up" order following receipt of a CODA BLOCK invite. Any unfilled shares on a "firm up" order will be cancelled back to the Subscriber at the completion of the auction. 

CODA opens for trading in the capacity of an ATS each trading day at 9:30:00 ET A.M. for all Reg NMS stocks as defined by Regulation NMS rule 600(b)(34) which defines a listed equity security as any equity security listed and registered, or admitted to unlisted trading privileges, on a national securities exchange. Upon request, Liquidity Seekers may enter orders and conditional interests prior to 9:30:00 A.M. ET to be held at the ATS until 9:30:00 A.M. ET at which time they will initiate an on-demand auction, route out or rest in CODA's MOF to participate in future auctions. CODA does not use any special order acceptance, handling or execution procedures at the open, during a re-open or following stoppage of trading during regular trading hours. At the open, during a re-open or following a stoppage, CODA accepts, handles, and executes orders and conditional interests as described in Part III, Item 11(c). 

At the start of regular trading hours, CODA handles unexecuted orders as described in Part III, Item 11(c). Any auction-initiating orders that were held at the ATS until the open (as described in Part III, Item 10(a)) will initiate an auction at that time. Following a stoppage of trading in a security during regular trading hours, unexecuted orders and trading interests in CODA are made available for execution. Unexecuted orders will not reinitiate an auction, but any resting orders and conditional interests may participate in future auctions as described in Part III, Item 11(c). 

CODA, which is operated by CODA Markets and its parent company/technology provider, PDQ, identifies and executes orders that can be matched or crossed in an agency capacity via CODA's on-demand, order-initiated auction matching protocols for all Reg NMS stocks. To address the varying liquidity needs and diverse workflows of its Participant base, CODA offers two auction types, CODA MICRO and CODA BLOCK, which are discussed individually and in detail below. CODA Markets does not have any Affiliates other than its Executive Officers, Directors and parent company, PDQ, a Control Affiliate. PDQ is a software development company to and the sole owner of CODA Markets. PDQ provides CODA Markets a license to the technology and software used to operate CODA. PDQ is responsible for the maintenance and continued development of the technology and software. PDQ may also provide operational and administrative support to CODA Both auction types, CODA MICRO and CODA BLOCK, utilize the on-demand, order-initiated auction market structure. Individual auctions are initiated by unique Liquidity Seeker orders. Only Liquidity Seeker orders deemed "marketable" upon receipt can initiate auctions. For purposes of auction initiation, "marketable" is defined as Buy orders priced greater than the national best bid and Sell/Sell Short orders priced less than the national best offer. Initiating orders are paused at CODA while the auction process occurs (the "Pause"). Once an auction is initiated, CODA sends "symbol-only" notifications, referred to as Request-for-Trades ("RFT") or Auction Alerts, to other Participants (both Liquidity Providers and other Liquidity Seekers depending on the Auction Type). Additionally and contemporaneously with the RFTs/Auction Alerts sent to Liquidity Provider Participants, RFTs/Auction Alerts are sent to CODA's MOF that holds and responds on behalf of resting orders and conditional interests from Liquidity Seekers. The RFT/Auction Alert process serves as the auction call and is used to attract liquidity from other Participants that will potentially trade with the initiating liquidity-seeking order. To minimize information leakage and protect initiating Liquidity Seekers' orders, the information included in RFT/Auction Alerts sent to Participants is limited to the ticker symbol from the initiating Liquidity Seekers' orders. Form ATS-N and other CODA materials refer to this RFT/Auction Alert format as "symbol only." Participants can receive additional information related to the trading opportunity on RFT/Auction Alerts, including a commission amount to be assessed if a trade occurs, midpoint pegging instructions (not supported in CODA BLOCK), and/or the duration of the auction type or matching engine logic for the corresponding auction (discussed in detail in Part III, Item 11 (c)). Exclusive to CODA MICRO and in order to provide Liquidity Seekers with additional flexibility, they can request in writing that CODA send RFT/Auction Alerts containing their full order detail (symbol, side, size and price) to one or more Liquidity Provider Participants instead of the default "symbol only" format. RFT/Auction Alerts sent to Liquidity Providers indicate a required minimum response size of 100 or 1000 shares for CODA MICRO or CODA BLOCK, respectively. Liquidity Seekers can rest orders in CODA's non-displayed MOF which receives RFT/Auction Alerts along with the Liquidity Providers. To rest orders in the MOF, Liquidity Seekers send Day orders or use custom TIF values as discussed in Part III, Item 7. The MOF responds on behalf of Liquidity Seekers' resting orders if the resting orders are executable in auctions initiated by other liquidity seeking orders. Orders resting in the MOF are referred to as "Managed Orders". Conditional interests also reside in the MOF. Unlike Managed Orders where the MOF responds to auctions on behalf of the order, Conditional interests are required to firm up in order to participate in an auction (discussed in detail in Part III, Item 9). 

CODA MICRO: During a CODA MICRO on-demand auction a liquidity seeking order is routed to CODA and subjected to a Pause of up to 20 milliseconds or as determined and specified by the Liquidity Seeker. Liquidity Seekers may opt to shorten the Pause time. The Pause may be shorter than the default 20 milliseconds based on preference or strategy of the Liquidity Seeker. Currently the shortest available Pause is 3 milliseconds. Following receipt of the order and standard risk checks, a RFT/Auction Alert is sent to all Liquidity Providers simultaneously and anonymously (unless directed otherwise by Liquidity Seeker as discussed in Part III, Item 14 (a)). Any executable contra side liquidity generated from the Liquidity Providers and/or the MOF during the Pause is crossed based on one of two CODA MICRO matching protocols as directed by the initiating Liquidity Seeker via a predetermined FIX tag and order handling configuration: 1) "First-to-respond-first-to-trade" (time priority for Liquidity Provider/MOF responses): a. Liquidity-seeking orders tagged to use CODA MICRO's "first-to-respond-first-to-trade" protocol trade with Liquidity Provider responses and Managed Orders on a first-come, first-served basis provided that the response is at or inside the National Best Bid and Offer ("NBBO") and at or better than the initiating order's limit price. b. Executed trades print individually to the Trade Reporting Facility ("TRF") as they occur. For example, a liquidity-seeking order configured for a 20ms Pause may execute and print in 2ms if a Liquidity Provider responds with executable contra side liquidity within the 2ms timeframe. 2) "Price improvement auction" (price / time priority for Liquidity Provider/MOF responses): a. Liquidity-seeking orders tagged to use CODA MICRO's "price improvement auction" protocol trade with Liquidity Provider responses and Managed Orders at the end of an auction order entry period. b. During the Pause, CODA assembles the Liquidity Provider responses and Managed Orders based on price (price improvement) / time priority into an Auction Book. c. Orders in the Auction Book are non-displayed and non-executable until the end of the auction. d. Orders in the Auction Book may be cancelled or replaced during the auction order entry period. e. At the end of the order entry period the Auction Book is closed and all orders are deemed firm. f. CODA rechecks the NBBO. The auction matching logic calculates the final execution price or prices for the trade(s) based on price (price improvement) / time priority. g. The liquidity-seeking order first trades against the best priced order that arrived in response to the RFT/Auction Alert during the Pause, then moves to the second-best priced order, if necessary, and so on until the entire liquidity-seeking order is filled, cancelled back, sent to the MOF or routed out as directed by the Liquidity Seeker. h. Trades are individually printed to the TRF at the completion of the auction. i. RFT/Auction Alerts for "price improvement auction" CODA MICROs are identified as such to encourage price competition and so that Liquidity Providers do not interpret the additional latency as a system defect or error. Additional CODA MICRO rules include: - Multiple CODA MICROs in the same symbol can run simultaneously. - Minimum fill Quantity instructions are supported and satisfied one-to-one (no aggregation). - Liquidity Seekers may enter orders with quantities within their established risk limits, including odd lots. - Odd lots are not accepted from Liquidity Providers. - Managed Orders are eligible to participate in CODA MICRO. - "Firm up" orders from invited conditional interests (discussed in detail in Part III, Item 9) may be eligible to interact with residual shares on the Liquidity Seeker's order following a CODA MICRO. - Trades print to the TRF as individual prints. - Any price improvement is awarded to the initiator. - CODA MICRO trades are priced at or within the NBBO CODA BLOCK: CODA BLOCK is CODA's on-demand block auction type. CODA BLOCK utilizes a multilateral, call auction price discovery model, providing trading opportunities for large orders and latent liquidity which may reside outside the NBBO, and therefore may execute outside the NBBO. As described below, CODA BLOCK and CODA are compliant with Rule 611 of Regulation NMS. A 30-second Pause serves as the approximate time length of the auction and order entry period during which orders are entered by Subscribers into a non-displayed auction order book. The CODA BLOCK matching algorithm (see "Pricing, Share Allocation and Trade Reporting" below) uses a series of rules resulting in a varying time-to-print at the end of the 30-second order entry window; therefore, 30 seconds is the approximate length of a CODA BLOCK auction. The CODA BLOCK auction process contains four stages: 1) Auction Initiation 2) Auction Alert & Participation 3) Auction Pricing, Share Allocation and Trade Reporting 4) Post Auction Auction Initiation - A CODA BLOCK eligible (as described below) order is sent to CODA and triggers the start of a CODA BLOCK auction. Only one CODA BLOCK auction can be in progress at a time for each symbol. A snapshot of the NBBO is taken at this time. Liquidity Seeker orders can initiate CODA BLOCK during the Core Trading Session with firm orders up until 3:59:00 P.M. Eastern Time. No CODA BLOCK auctions will be initiated after that time. As with other auction types only Buy orders priced greater than the NBB and Sell/Sell Short orders priced less than the NBO upon receipt are eligible to initiate a CODA BLOCK auction. A minimum order quantity is required to initiate CODA BLOCK based on the following criteria (market capitalization data is updated in the morning of each trading day): - Large Market Capitalization (greater than $10 billion market capitalization). Initiation order size must be at least 10,000 shares. - Middle Market Capitalization (greater than $2 billion and up to $10 billion market capitalization). Initiating order size must be at least 5,000 shares. - Small Market Capitalization or Smaller ($2 billion or smaller market capitalization). Initiating order size must be at least 2,000 shares. - "High Price" (Reg NMS stocks priced greater than or equal to $100.00 per share) are subject to the aforementioned Small Market Capitalization requirements. - Odd lot orders are not accepted in CODA BLOCK auctions and will be rejected. - Mixed lot orders are accepted in CODA BLOCK auctions, but only the round lot portion will be eligible for participation in CODA BLOCK auctions. The odd lot portion of a mixed lot order tagged for CODA BLOCK is cancelled back to the Subscriber following a trade if the residual quantity is less than 1000 shares. Stocks priced less than $1.00 are not eligible for CODA BLOCK and orders in these stocks will be rejected. - If the NBB is less than $1.00 upon receipt of an initiating order, the order will be rejected. - No CODA BLOCK auction will execute with a trade price less than $1.00 (CODA BLOCK auction pricing is discussed below). Following successful eligibility and CODA standard risk checks on the initiating order the "30-second" order entry period begins (discussed further under "Auction Alert & Participation" below) and no further CODA BLOCK auctions can be initiated in that symbol until the end of the current CODA BLOCK auction. All CODA BLOCK auction orders received in that symbol while a "30-second" order entry period is open are included in the existing CODA BLOCK auction for that symbol as "participating orders" (discussed further below). CODA will monitor for repeated cancelling by initiators and will address and take action by disabling a Participant's access to CODA BLOCK as it deems necessary. Auction Alert & Participation - A successful initiation of a CODA BLOCK auction is followed by the distribution of CODA BLOCK Auction Alerts and the opening of a "30-second" order entry period. CODA distributes Auction Alerts to its Participants (both buy-side and sell-side) using its "symbol only" RFT, similar to CODA MICRO. The alerts notify Participants that a CODA BLOCK auction has been initiated in that symbol and is in progress. Participants (both Liquidity Seekers and Liquidity Providers) can receive Auction Alerts at three distinct times, in order to accommodate the varied trading workflow needs and latency sensitivities of CODA and CODA BLOCK's diverse Participant community. The first of the three Auction Alerts, Phase 1 Auction Alert, is sent at the start of this stage. Auction Alerts are distributed to Participants via IOI, the PULSE download (see detail below), Instant Message ("IM"), OMS/EMS platforms, direct FIX connections and other third-party messaging platforms and networks. If any alert distribution platforms or networks require "Side" in their specification, then CODA will send both a Buy Auction Alert and a Sell Auction Alert to the platform or network to avoid disclosing the direction of the initiating order. The Auction Alerts can also include the start and stop time for the order entry period. The PULSE application is one of the available options to deliver symbol-only Auction Alerts to users at the start of each CODA BLOCK on-demand auction. In addition to the symbol, each Auction Alert shows a timestamp, auction ID, status, symbol sector/industry and an indicator if the user was logged out of PULSE when a particular auction was initiated. PULSE users may filter Auction Alerts based on their own symbol list or by sectors. PULSE also provides chat-based support services to address any user questions or issue with the product. Additional information about PULSE is available in Part II, Item 5(a). Orders received during the order entry period are placed in the CODA BLOCK auction order book for that symbol as participating orders. There is no time priority in the auction pricing process (allocation rules are described later in this document); therefore, a Subscriber can respond to any of the three Auction Alerts at any time. CODA BLOCK enforces the following requirements on participating orders: - Participating orders may be priced below, at, inside or above the NBBO. - A minimum order quantity of 1,000 shares is required for a participating (responding) order. - Managed Orders and "firm up orders" from invited conditional interests are eligible for participating in CODA BLOCK auctions if they meet the aforementioned criteria. The Phase 2 and Phase 3 Auction Alerts are designed to accommodate quantitative, algorithmic and conditional interest Participants. The Phase 2 Auction Alert is sent approximately 29.7 seconds after the Phase 1 Auction Alert. This time is also 300 milliseconds prior to the end of the "30-second" order entry period. The Phase 2 Auction Alert is the invite to all eligible conditional interests. The Phase 3 Auction Alert is the final Auction Alert and is sent 10 milliseconds prior to the end of the "30-second" order entry period. Managed Orders in the CODA system that are CODA BLOCK auction eligible are reserved for the auction book at this time. The Auction Alerts are sent to Participants according to the following schedule: - Phase 1 Auction Alert: Time ~0 seconds - Phase 2 Auction Alert: Time ~29.7 seconds (29 seconds and 700 milliseconds). - Phase 3 Auction Alert: Time ~ 29.990 seconds (29 seconds and 990 milliseconds). Participating orders in the auction order book may be entered, replaced or cancelled at any time during the order entry period. All participating orders in the CODA BLOCK auction order book are non-displayed. All participating orders and the initiating order are not executable until the end of the "30-second" order entry period. The stage is complete at the end of the "30-second" order entry period. At that time all participating orders in the auction order book are deemed firm and cannot be cancelled. Auction Pricing, Share Allocation and Trade Reporting - After the thirty-seconds, which includes the aforementioned initiation, alert and response processes, the CODA BLOCK auction matching logic determines the price for the auction, the allocation of shares to each Participant, and the sending of trade reports as required to a TRF. CODA rechecks the NBBO to establish the current NBBO for pricing and allocation as well as identifying the protected markets' "top of book" should the CODA BLOCK auction be priced outside the NBBO requiring CODA to fulfill any Rule 611 of Regulation NMS obligations. All CODA BLOCK auction eligible orders are aggregated in the CODA BLOCK auction order book at their most aggressive (i.e., highest priced Buy orders/lowest priced Sell/Sell Short orders) price levels. Since a CODA BLOCK auction is a multilateral trading environment that allows multiple buy orders and multiple sell/sell short orders to compete in a single auction, there may be multiple orders to buy and sell up to or down to any given price level. Pricing: CODA BLOCK's auction pricing logic determines the single price where the most aggregated buy shares can trade with the most aggregated sell/sell short shares while taking into consideration all of the following: 1) All Limit prices. 2) All Pegged Orders, the limit price on the pegged orders and any peg offset value specified on the order (Pegged orders are pegged to the NBBO snapshot taken at the end of the order entry period). 3) Minimum Fill Quantity instructions (CODA BLOCK satisfies Minimum Fill Quantity instructions) a. Unless Subscriber specifies another value on the order, CODA BLOCK enforces a default 100 share minimum fill quantity instruction on all initiating and participating orders. 4) Maximum contra is not supported in CODA BLOCK (discussed later in this Form). 5) Self-trade prevention is not supported in CODA BLOCK, but is actively monitored by CODA. CODA addresses self-trade concerns with Subscribers directly as needed. 6) CODA BLOCK's Passive Order Rule ("POR") a. Only applied when the auction price will be outside the NBBO. b. Designed to prevent an order that is small in size and passive in price from having an undue influence on the auction trade price (when compared to the aggregate share volume of orders on the passive side of the auction trade). c. The POR establishes a threshold to determine which, if any, passive (non-marketable) orders should be excluded from participating in a specific CODA BLOCK auction. d. The POR inputs include all orders eligible to participate on the passive side of a CODA BLOCK auction and the share-weighted average price of these orders collectively. The POR threshold is established and defined as twice the distance of the aforementioned share-weighted average price from the NBBO midpoint. The NBBO used for the calculation is from the NBBO snapshot taken at the end of the order entry window. Any orders priced beyond the threshold in a given auction are excluded and will not receive any allocation in that CODA BLOCK auction. All orders on the passive side of a CODA BLOCK auction are subject to the POR if the CODA BLOCK auction is to be priced outside of the NBBO. 7) CODA BLOCK's Liquidity Protection Rule ("LPR") a. Only applied when the auction price will be outside the NBBO. b. Designed to prevent an auction trade from executing at an unreasonable distance outside the spread given the size of the execution and the liquidity profile of the symbol. c. The LPR is driven by an equation that is calibrated individually for every Reg NMS stock based on the pattern of its trades over the last twenty trading days (unlike the POR which uses a static formula for each auction). The calibration methodology is designed to reflect the typical price variance of each stock as a function of its notional turnover. The LPR takes the size of a potential CODA BLOCK print as an input and returns the maximum distance the CODA Block engine will allow the auction to go up outside the NBBO as the output. d. If the auction trade price would be outside of that threshold, the orders passively priced outside of that threshold are deemed ineligible and the auction is repriced and reallocated. e. As discussed in Part II, Item 5(c), registered users of the LPRC can enter an NMS stock symbol and auction trade quantity, and the LPRC output is a numerical and graphic representation of the Auction Trade Price band used by the Liquidity Protection Rule ("LPR") in CODA BLOCK on that trading day. Registered users of the LPRC may request a daily file containing the same LPR output data available on CODA Markets' website. That file may be delivered via FTP or the user's preferred delivery methodology. 8) If CODA BLOCK determines that the maximum number of shares that can trade is equal at multiple price levels, CODA BLOCK prices the auction at the price where the most shares can trade that is closest to the NBBO midpoint from the snapshot taken at the end of the order entry period. Trade Size Requirements: The CODA BLOCK auction trade size must satisfy CODA BLOCK Trade Size Requirements as follows: 1) CODA BLOCK auctions with an execution price at or within the NBBO: a. Large Market Capitalization (greater than $10 billion market capitalization): The Auction trade size minimum is 5,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade that is less than 5,000 shares, the CODA BLOCK auction and all related orders are canceled. b. Middle Market Capitalization (greater than $2 billion and up to $10 billion market capitalization): The Auction trade size minimum is 1,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade that is less than 1,000 shares, the CODA BLOCK auction and all related orders are canceled. c. Small Market Capitalization or Smaller ($2 billion or smaller market capitalization): The Auction trade size minimum is 1,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade that is less than 1,000 shares, the CODA BLOCK auction and all related orders are canceled. d. "High Price" (Reg NMS stocks priced greater than or equal to $100.00 per share) are subject to the aforementioned Small Market Capitalization requirements. 2) CODA BLOCK auctions with an execution price outside the NBBO: a. Large Market Capitalization (greater than $10 billion market capitalization): The Auction trade size minimum is 10,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade that is less than 10,000 shares, CODA BLOCK reprices the auction without the passively priced orders in the auction book to determine if a trade can occur at or within the NBBO. If not, the CODA BLOCK auction and all related orders are canceled. b. Middle Market Capitalization (greater than $2 billion and up to $10 billion market capitalization): The Auction trade size minimum is 5,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade which is less than 5,000 shares, CODA BLOCK reprices the auction without the passively priced orders in the auction book to determine if a trade can occur at or within the NBBO. If not, the CODA BLOCK auction and all related orders are canceled. c. Small Market Capitalization or Smaller ($2 billion or smaller market capitalization): The Auction trade size minimum is 2,000 shares. If the CODA BLOCK auction price and share allocation results in an auction trade which is less than 2,000 shares, CODA BLOCK reprices the auction without the passively priced orders in the auction book to determine if a trade can occur at or within the NBBO. If not, the CODA BLOCK auction and all related orders are canceled. d. "High Price" (Reg NMS stocks priced greater than or equal to $100.00 per share) are subject to the aforementioned Small Market Capitalization requirements. 3) If CODA's protected markets "top of book" snapshot shows more shares available in aggregate at the protected markets "top of book" than the pending CODA BLOCK auction trade size, then CODA, if possible, will reprice and reallocate the CODA BLOCK auction, not including the passively priced orders outside the NBBO, and price the auction at or inside the NBBO. If not possible, the CODA BLOCK auction and all related orders in the auction are cancelled. If CODA BLOCK Trade Size Requirements are satisfied the allocation process is effected as described below. Primary Allocation: If an initiating or participating order is priced at or through the auction trade price, the order will be allocated shares from the auction order book as follows: 1) The initiating order receives 100% allocation priority. a. If the initiating order's limit price, minimum fill quantity or other order instruction prevents it from trading at the auction's trade price, then the initiating order will not be included in the allocation process. (If an initiating order is not included in the CODA BLOCK auction allocation process due to its limit price or other order instructions, it will not result in the cancelation of the auction.) 2) Participating orders receive a quantity weighted pro-rata allocation. a. If a participating order's limit price, minimum fill quantity or other order instruction prevents it from trading at the auction's trade price, then the participating order will not be included in the allocation process. b. Multiple orders from the same Subscriber on the same side are not aggregated for pro-rata allocation and calculation purposes. 3) If the auction price is outside the NBBO, then Rule 611 of Regulation NMS Trade Through requirements are triggered. In these cases, CODA BLOCK will reduce the number of shares allocated to CODA BLOCK Participants by the number of shares shown as protected "top of book" according to Rule 611 of Regulation NMS and CODA BLOCK's NBBO snapshot at the end of the 30-second order entry window. CODA will route orders outside CODA to satisfy the requirements of Rule 611 of Regulation NMS in an agency capacity. Any shares filled at the protected prices will be allocated according to the "Secondary Allocation" described below. 4) The primary allocation process will not allocate shares in mixed or odd lots. If the final 100 shares need to be allocated to one participating order while there are several participating orders in the CODA BLOCK auction order book, the final 100 shares are allocated to the participating order based on price/time priority (price and time stamp on new order receipt). TRF Trade Reporting: As detailed in Part III, Item 21, once the auction trade price and the primary allocation is determined, a trade report is generated as a single price and a single trade execution. This is the media print to the TRF. CODA sends the trade report to a TRF at this time along with any required Intermarket Sweep Orders ("ISO") (described below). Regulation NMS Rule 611 ISO Sweep (if necessary): To comply with Rule 611 of Regulation NMS, if the auction trade price is outside the NBBO, CODA will route ISOs to access the liquidity deemed as protected markets "top of book" according to CODA's "protected market" snapshot. CODA will send ISO orders to the protected markets in an agency capacity; therefore, the CODA BLOCK auction trade size may be adjusted as necessary and to comply with Rule 611 of Regulation NMS. The initiator's 100% allocation priority from the primary allocation is maintained during any auction trade size adjustment. Fills for participating orders are adjusted on a volume weighted pro-rata basis if necessary. If an auction trade size adjustment would result in a violation of CODA BLOCK's auction Trade Size Requirement then CODA, if possible, will reprice and reallocate the CODA BLOCK auction, not including the passively priced orders outside the NBBO, and price the auction at or inside the NBBO. Should that not be possible, the CODA BLOCK auction and all related orders in the auction are cancelled. The ISO order(s) to the protected markets and the auction trade print to the TRF are sent contemporaneously. Secondary Allocation (if necessary): To comply with Rule 611 of Regulation NMS, if CODA receives full or partial fills on any of the ISO orders, the filled shares will be allocated on a quantity weighted pro-rata basis to the aggressively priced orders (i.e., Buy orders in a CODA BLOCK auction with an auction trade price greater than NBO/Sell orders in a CODA BLOCK auction with an auction trade price less than NBB) that received allocations in the auction (which may include the initiator). Post Auction - Immediately after the auction price, share allocation, and TRF reporting has been completed: Subscriber execution reports: Subscribers receiving fills from CODA BLOCK will receive one fill at a single price. That fill price reflects the auction price unless the Participant receives secondary allocation shares as described above. Participants receiving secondary allocation shares in addition to primary allocation shares will receive a single fill at the average price. Post auction residual processing: a. All unfilled or partially filled IOC orders are cancelled back to the Participant. b. Day orders remain active as Managed Orders as follows: i. If an initiating or participating order received in response to an Auction Alert and tagged for CODA BLOCK has residual quantity, it is eligible to interact with future CODA BLOCK auctions, but not eligible to interact with other CODA auction types. ii. If the remaining quantity on a CODA BLOCK auction Day order is less than 1,000 shares, then CODA BLOCK will cancel the order. iii. All CODA BLOCK auction orders that do remain active as Managed Orders will maintain the 100-share minimum fill quantity unless another value is specified by the Subscriber. c. Conditional interests that send Day orders as a firm up to a CODA BLOCK invites are cancelled after the auction. d. Managed Orders (not designated as CODA BLOCK-only) that were included in a CODA BLOCK auction will remain live and active as Managed Orders in CODA. Clearance and settlement: CODA BLOCK's clearing and settlement procedures are consistent with other CODA auction types. At the completion or cancellation of a CODA BLOCK auction, the symbol is again available for initiation of a new CODA BLOCK auction. CODA ONE is a feature allowing Liquidity Seekers to enter one or more orders (in the form of a list, basket or program) to CODA which in turn, based on the characteristics of the individual orders, will direct each order to either CODA BLOCK or CODA MICRO. Subscribers instruct CODA to use CODA ONE via a FIX Tag on an order-by-order basis. - Any orders eligible for CODA BLOCK, based on the aforementioned CODA BLOCK initiation requirements, will initiate a CODA BLOCK auction (i.e., quantity, market capitalization, order type). - If an order does not qualify to initiate a CODA BLOCK auction, the order will initiate CODA MICRO (if eligible), with "price improvement auction" matching logic. - CODA ONE accepts both Day and IOC orders. - Fills, partial fills and cancels are sent to the initiating Liquidity Seeker at the completion of each individual CODA MICRO or CODA BLOCK auction. - Non-marketable Day orders sent with CODA ONE instructions can post to the Managed Order Facility without initiating an auction. Subscribers may enable a maximum contra-size feature that will prevent orders from executing against contra-side orders of greater size. This feature supports a multiplier setting which allows executions with contra-side orders that are larger in quantity, but within a specific threshold. For example, a Subscriber may request a maximum contra-size setting of two times their quantity on any potential execution. This feature is available to Liquidity Seekers using Managed Orders and to Liquidity Providers. Any cancels generated as a result of this feature will not contain information indicating that the reason for the cancellation was a larger initiator, and therefore, the parties will not know this feature was the cause of the cancellation. This feature is not available in CODA BLOCK. Subscribers may submit orders with a minimum fill quantity on an order-by-order basis. Subscribers may contact CODA to request a default minimum fill quantity at either the Subscriber or session level. CODA does not aggregate contra side orders to satisfy a minimum fill execution quantity of a liquidity-seeking order except as described in CODA BLOCK. CODA enforces self-trade prevention at the MPID level in CODA MICRO. CODA BLOCK does not support self-trade prevention due to the multilateral auction process (defined in Part III, Item 7 (a). Self-trade prevention is a non-configurable setting in both CODA MICRO and CODA BLOCK. Character limit exceeded. Please refer to the attachment for Part III, Item 11(c) for additional information on the handling of errors. 

CODA MICRO: Subscribers (both Liquidity Seekers and Liquidity Providers) may elect to not trade with or block any number of specified counterparties in CODA MICRO auctions. Subscribers can identify such counterparties to CODA Markets by name or by reference to their own historical executions. If identified to CODA Markets by name, CODA Markets will not confirm or deny to such identifying Subscriber any active subscriptions of any other Subscribers (unless authorized to do so by the Subscriber being identified), but CODA Markets will satisfy the do-not-trade request if the identified counterparty is a CODA Markets Subscriber. Sponsored Users may also submit a do-not-trade request with proper disclosure to their sponsoring broker Subscriber. CODA enforces the block at the MPID level. Therefore, if a do-not-trade request is in effect between "Subscriber A" with a MPID of ABCD and "Subscriber B" with a MPID of WXYZ, then any trades that would otherwise occur in CODA MICRO, as discussed throughout this Form between ABCD and WXYZ, will result in a nothing done. Requests may be delivered verbally or in writing by the Subscriber. CODA can process and effect counterparty blocking requests intraday or on a scheduled date. If a trade does not occur due to an active do-not-trade request by a Subscriber, neither the identifying Subscriber nor the identified counterparty will be notified that this was the reason the order was cancelled or for a nothing done. Two or more Subscribers may request to trade exclusively with each other in CODA MICRO. From the Liquidity Seeker's perspective, its RFT/Auction Alerts will only be sent to the exclusive Liquidity Provider(s) it has designated. From the Liquidity Provider's perspective, it will only receive RFT/Auction Alerts from the exclusive Liquidity Seeker(s) it has designated. The request can be set as a default for the Subscribers, or specified at the session level or on an order-to-order basis. As described previously, CODA Markets will not confirm or deny whether any firm or person is a CODA Subscriber, but Subscribers may disclose their subscription status/participation in CODA to third parties at their discretion, for the purpose of arranging exclusive trading or otherwise. As previously mentioned, CODA MICRO enforces self-trade prevention at the MPID level. Subscribers cannot opt out of enforcement of self-trade prevention in CODA MICRO. CODA BLOCK: Counterparty restriction is not supported in CODA BLOCK auctions. As previously mentioned, CODA BLOCK does not enforce self-trade prevention due to the multilateral auction process (defined in Part III, Item 7 (a)). 

CODA does NOT display any orders or quotes in the NMS Stock ATS to any Person (not including those employees who are operating the system). Information from an order can be displayed in an invite to a conditional interest as described below and in Part III, Item 9(a). Conditional interests are supported by CODA and discussed in detail in Part III, Item 7(a) and Part III, Item 9(a). The process of inviting a conditional interest to be firmed up may be considered an expression or display of trading interest. - In CODA MICRO, invites to conditional interests represent current executable trading opportunities. As a result, Participants using conditional interests in CODA MICRO are expected to maintain a 90% or greater firm up rate. Invites are delivered to Participants with live conditional interests representing an executable trading interest. Delivery of the invite is sequential and based on price/time priority amongst the resting conditional interests until the initiator's order is filled. Invites contain the symbol, side, price and size (up to the quantity on the conditional interest being invited) for which CODA is requesting the conditional Participant to firm up. - A CODA BLOCK invite to a conditional interest represents nothing more than an alert that there is an in-progress on-demand CODA BLOCK auction for a particular Reg NMS stock. The CODA BLOCK conditional invite is therefore "symbol-only" by nature and does not represent the presence of an executable contra-side order. Regardless of side and price, invites are delivered contemporaneously to all Participants with a live CODA BLOCK eligible conditional interest in the same symbol as the in-progress CODA BLOCK on-demand auction. Invites contain symbol, side, price and size, but (as previously mentioned) the values echo the values from the conditional interest being invited. As part of the on-demand auction process, and through "symbol-only" Auction Alerts or RFTs, CODA anonymously expresses an initiator's interest to run an on-demand auction in the Reg NMS stock identified in the "symbol-only" alert. As discussed in detail in Part III, Item 11(a) and (c), and by default, RFTs or Auction Alerts do NOT include the side, size or price from the auction-initiating order. "Symbol-only" RFTs or Auctions Alerts are delivered to both Subscribers and Sponsored Users, including buy side traders who access CODA through a sponsoring broker Subscriber. Participants may receive CODA BLOCK RFTs or Auction Alerts through channels such as FIX, PULSE, Bloomberg and their OMS/EMS. All CODA MICRO RFTs or Auction Alerts are delivered via FIX. On request of the Participant, CODA can filter the RFTs or Auction Alerts based on factors such as auction type, symbol sector, and a static symbol list. Orders responding to auctions or resting in CODA's MOF are never displayed. 

The ATS via its router, FLARE, allows Liquidity Seekers, at their discretion, to route out to external trading centers, including exchanges, ATSs, Single Dealer Platforms, and brokers. Examples of ways that orders can be routed via FLARE include residual liquidity from an initiating CODA MICRO order, non-marketable orders and orders instructed to be sent to other trading centers before (or instead of) initiating an auction at CODA. All outbound routing via FLARE is at the discretion and direction of the Liquidity Seeker Subscriber. Participants work with CODA sales, operations and support teams to configure one or more strategies for routing out of the ATS. Subscribers acting in the capacity of a Liquidity Seeker use FIX tags to direct orders to the routable or non-routable strategies. Participants may also opt for a default routable configuration. Affirmative instruction is obtained during the configuration discussions mentioned above and on an order-by-order basis via FIX tags. Liquidity Seeker orders directed to CODA BLOCK are not eligible for routing. Liquidity Provider orders are never eligible for routing. 

The CODA BLOCK auction type does not allow the initiation of a new CODA BLOCK auction after 3:59:00 P.M. ET. All other features of the ATS operate as normal during the close. 

Broker Dealers (when using the ATS as Liquidity Seekers): CODA Markets assesses a negotiated per-executed-share fee to Broker Dealer Liquidity Seekers for shares traded in the CODA. That fee may be in the form of a charge or a rebate. The charge assessed or rebate provided to any Broker Dealer Liquidity Seeker may vary based on factors including: 1) Auction Type (e.g., CODA MICRO, CODA BLOCK); 2) Order Type (e.g., firm, conditional); 3) Adding (Managed Order Facility) vs. Taking (Initiating); 4) Security Price (e.g., above a dollar vs. sub-dollar); 5) Strategy (routable vs non-routable). Strategy-based pricing can be considered bundled pricing. For example, a Liquidity Seeker can be charged a flat fee for all executed shares regardless of executing in CODA or an away venue. CODA Markets reserves the right to offer broker dealer Liquidity Seekers a tiered pricing schedule based on volume or large (block) trades. At the time of this filing, there is no tier-based pricing in place for Liquidity Seekers. Liquidity Seeker usage of FLARE may be charged based on established per share executions fees (or rebates), a profit-sharing agreement or a cost-plus execution model. Liquidity Seeker Subscribers who are broker dealers may charge their own clients an amount higher than the Subscriber's actual and CODA Markets' own cost of execution through FLARE. CODA Markets and the broker dealer Subscriber may split the difference between the fee charged by the Subscriber to its clients and the actual cost of execution through FLARE to CODA Markets. CODA Markets can refer to this as profit-sharing. A cost-plus model involves CODA Markets charging a Subscriber a negotiated value on top of CODA's execution costs when using FLARE. Broker Dealers (when using the ATS as Liquidity Providers): CODA Markets assesses a per-executed-share fee to the broker dealer Liquidity Provider for shares traded in CODA. That fee may be in the form of a charge or a rebate and is identified in the "Request-for-Trade" message sent to the Liquidity Provider as part of the ATS's on-demand auction matching process. The fee charged or rebated to the Liquidity Provider is determined by the amount charged or rebated to the initiating Liquidity Seeker of each on-demand auction. CODA Markets offers Liquidity Providers the following participation-based trading credits: CODA MICRO: Average Daily Volume: Liquidity Providers with a qualifying ADV are provided a per-executed-share rebate for all shares traded in CODA MICRO during the month. This rebate is a discount from the fees/rebates assessed for daily trading discussed above. Large (Block) Trades: Liquidity Providers are provided a per-executed-share rebate for trades in CODA MICRO of qualifying size. This rebate is a discount from the fees/rebates assessed for daily trading discussed above. CODA BLOCK: Average Daily Volume: Liquidity Providers with a qualifying ADV are provided a discounted rate for all shares executed in CODA BLOCK during the month. Institutions (whether accessing the ATS as Liquidity Seekers or Liquidity Providers): CODA Markets assesses a negotiated per-executed-share fee to Institutions for shares traded in the ATS. Per executed share rebate and fees, currently range from a $(0.0030) rebate to a $0.0100 fee for brokers and institutions. CODA Markets passes through certain regulatory fees (including FINRA's Section 3 fee and Trading Activity Fee ("TAF") for Subscribers who are not FINRA members). 

FLARE is a service of CODA. All orders are first routed to CODA and based on instructions received from Subscribers and the eligibility requirements discussed in Part III, Item 11(c), can then be executed in the ATS, routed out via FLARE, rest in CODA's MOF or cancelled back to the Subscriber. As noted above in Part III, Item 19(a), Subscribers opting to interact with both the ATS and away markets via FLARE can be assessed a bundled fee (i.e., a flat rate for executed shares in both CODA and FLARE) or explicit fees (i.e., varying rates for executed shares in CODA versus away markets). 

The range for the CODA MICRO ADV Liquidity Provider Tier and Large Trade Credit is a $0.0001 to $0.0006 per executed share rebate from agreed upon rates. The range for the CODA BLOCK ADV Liquidity Provider Tier is a $0.0005 to $0.0010 per executed share rebate from agreed upon rates. 

CODA Markets, at its discretion, may choose to limit, suspend or stop trading on CODA in all or individual NMS stocks. Reasons for the stoppage may include regulatory, active street-wide trade halts, unreliable market data, technology or platform issues, programming errors, or systemic issues. CODA Markets, at its discretion, can suspend trading at any time, including the suspension of trading in individual NMS stocks for reasons such as, approaching Regulation ATS Fair Access and Regulation SCI volume thresholds. By default, if trading is suspended in a security during regular trading hours, open orders and trading interests in the ATS will be cancelled. Any new orders received by CODA while a security is disabled or halted will be rejected. 

Following an execution, all sides of the trade are reported to a Trade Reporting Facility ("TRF") to post the trade on the consolidated tape. CODA becomes a counterparty to both or all (CODA BLOCK) sides on each trade. Currently, CODA reports executed trades to the FINRA/NYSE TRF, but reserves the right to report to any other registered TRF. At this time, CODA is only connected to the FINRA/NYSE TRF. CODA reports all executions on its ATS under the MPID, "CODA". CODA MICRO executions are printed to the tape individually. In other words, if an auction-initiating order trades with two responding orders, then two trades are printed to the tape (potentially at unique prices). CODA BLOCK executions are printed to the tape as a single multilateral trade. In other words, if an auction-initiating order trades with two responding orders, then one trade is printed to the tape (at a single auction trade price). Individual Participants in the trade receive execution reports only for their respective executed quantity. Routed orders are executed at away Trading Centers and reported to the TRF by the away Trading Centers. 

CODA utilizes BofA Securities, Inc. (Broadcort division) for clearing and settlement. All trades on the ATS are submitted to and cleared by BofA Securities, Inc. (Broadcort division). For both CODA MICRO and CODA BLOCK, BofA Securities, Inc. submits transactions to NSCC for clearance and DTCC for settlement. Subscribers to the ATS, both broker-dealers and qualified institutions, must have arrangements with a clearing firm. Executions that occur via FLARE (router) are also submitted to and cleared by BofA Securities, Inc. (Broadcort division). CODA Markets has an additional clearing arrangement with Electronic Transaction Clearing, Inc. to clear and settle transactions as described above with BofA Securities, Inc. At this time, CODA Markets does not clear any trades with Electronic Transaction Clearing, Inc. Should CODA Markets decide to clear all or a portion of trades via Electronic Transaction Clearing Inc., or use the arrangement as a backup, CODA Markets will provide advance notice to Subscribers and file an amendment to Form ATS-N. 

CODA Markets may clear Broker-dealer Subscribers through QSR, Correspondent or ACT clearing methodologies. CODA Markets clears non-broker-dealer, or Institutional Subscribers, through delivery versus payment ("DVP"). 

CODA uses the Securities Information Processor ("SIP") as its market data feed. Market data is provided to CODA by PICO as noted in Part II, Item 6. The market data feed is used to ensure the ATS is executing trades at prices consistent with its matching logic, rules of engagement, Reg NMS and other relevant rules and regulations. Throughout each trading day CODA monitors the market data feed for the NBBO, price bands, short sale restrictions, trade halts and Limit Up Limit Down ("LULD"). Based on this information which is disseminated to its systems in real time from the market data feed, CODA will restrict execution prices and disable trading in halted symbols as required. Each Auction Type checks the market data feed upon receipt of a liquidity-seeking order to establish marketability and determine if the order is eligible to initiate an auction based on marketability. As previously discussed, only marketable orders will initiate auctions. CODA MICRO auctions using the price improvement auction matching protocol and CODA BLOCK auctions recheck the NBBO at the end of the auction to establish the NBBO used for pricing market and pegged orders, as well as pricing and executing the auction. Additionally, if a CODA BLOCK auction's trade price is set outside the NBBO, the market data feed is used to identify protected quotes in the broader market, finalize the auction trade price and Participant allocations, and establish the details of CODA Markets' responsibility to perform a Regulation NMS Rule 611 ISO Sweep (as discussed in Part III, Item 7). CODA performs several per order risk checks on Subscriber orders upon entry. The Aggressive Limit Order Check rejects orders that are priced over 10% above (on buy orders) or below (on sell orders) the NBBO at time of receipt. Additionally, if the stock is priced less than $10.00, the Aggressive Limit Order Check uses a static value of $1.00 instead of 10%. CODA uses market data to establish the limits, perform this check and reject orders in violation of the limit. CODA's Liquidity Protection Rule (discussed in Part II, Item 5) uses historical market data provided by the SIP as the data input to calculate the price bands used in CODA BLOCK. The LPR price bands are also made available along with other symbol-specific, SIP-provided market data on CODA Markets' website via the Liquidity Protection Rule Calculator. During regular trading hours, should CODA lose its connections to the market data feed, CODA will suspend trading in the ATS until the market data feed connection is reestablished. As mentioned in Part III, Item 20, CODA may suspend trading in the ATS if it determines its market data feed is providing inaccurate or unreliable data. As noted in Part III, Item 6, CODA maintains a backup market data connection through SpiderRock.
