        <taPart3Item3aExcludngSumryDtls>A Subscriber can be excluded from the ATS if the Subscriber no longer satisfies the eligibility requirements for acceptance as a Subscriber.

Additionally, the operation of the ATS is continuously monitored by the ATS's trading operations team ("Trading Operations") to ensure the smooth and correct functioning of the system as well as adherence to the ATS's operating procedures and the applicable securities rules and regulations. Trading Operations can monitor order entry port status, order acknowledgement latency, and market data quality, in addition to detailed metrics on order entry rates, open and executed exposures, and executed volumes.
Trading Operations monitors to determine whether Subscribers are  sending orders in excess of 100 orders per second or a single order with notional value greater than $5 million. Any orders entered in excess of these limits is rejected by the ATS, and Subscribers are reminded of the limits.

In addition to real-time monitoring, Trading Operations reviews any  anomalies in the activities of the ATS using end-of-day reports. These reports include T+1 clearing breaks and same entity crosses. In the event one of the preceding occurs, Trading Operations may, among other actions, halt the activity of a Subscriber or set of Subscribers and/or an NMS Stock or set of NMS Stocks in order to contain the impact of a problem while pursuing a resolution.

BOATS may also exclude a Subscriber from trading on the ATS if the Subscriber breaches the written standards as outlined in Part III, Item 2(b). </taPart3Item3aExcludngSumryDtls>

      <taPart3Item4aHrsOfOperation>BOATS operating session is overnight from 8:00 p.m. ET to 4:00 a.m. ET, dependent on the availability of the NYSE Trade Reporting Facility ("TRF") to report trades the following trading day. For example, the ATS operates on Sunday evening from 8:00 p.m. ET until 4:00 a.m. ET on Monday. However, BOATS does not conduct a trading session on Fridays from 8:00 p.m. ET to 4:00 a.m. ET Saturdays because the TRF is not available to report trades on Saturday. Likewise, there is no trading session on Christmas Eve because the TRF is not open on Christmas, but BOATS may operate in its overnight trading session beginning on Christmas night if the TRF is open and available for trade reporting on the following day.

On the days of operation, Subscribers may submit test orders to the ATS at 6:15 p.m. ET, and bona-fide orders are accepted at 8:00 p.m. ET. Matching occurs on a price-time priority basis during BOATS operating hours from 8:00 p.m. ET to 4:00 a.m. ET. At 4:00 a.m. ET, BOATS no longer accepts orders, however matching may still occur after 4:00 a.m. ET while BOATS clears any resting orders in the order book. Trades executed during BOATs overnight session are reported to the TRF before 8:05 a.m. ET following the hours of operation.

Subscribers access BOATS via a Financial Information Exchange ("FIX") connection. Such access is available to Subscribers through an internet protocol address via communications that are compliant with the FIX API provided by the ATS. BOATS and MEMX support FIX 5.0 and Simple Binary Encoding.

      <taPart3Item7AOrdrTypExplain>Order Types

BOATS only accepts limit day orders ("orders"). An order that is posted on the ATS and immediately executed (matched with a contra interest) against an order that was previously posted on the ATS is referred to as a "marketable" order; the order that was previously posted on the ATS is referred to as a "resting" order.

For example:

ORDER A: tagged with identifier CLIENT1, a LIMIT DAY buy order to buy 500 shares of ABC @ $10 is entered in the system at 11:00 p.m.;

ORDER B: tagged with identifier CLIENT2, a LIMIT DAY sell order to sell 500 shares of ABC @ $11 is entered in the system at 11:01 p.m.;

ORDER A and ORDER B are "resting" orders i.e., they are posted on the ATS and they are awaiting a contra interest;

ORDER C: tagged with identifier CLIENT3, a LIMIT DAY sell order to sell 500 shares of ABC @ $10 is entered in the system at 11:02 p.m.;

ORDER C is immediately executed (matched with a contra interest) @ $10 at 11:02 p.m. against resting ORDER A;

ORDER C is a marketable order

ORDER B remains resting on the ATS and will be held on the ATS until the end of the session, until the order is canceled, or until it is executed (matched with a contra interest)

All orders on the ATS order book are canceled at the end the trading session.

The only time-in-force instruction accepted by the ATS is DAY.
Routing
Orders are not routed away from BOATS. Message Priority
Incoming orders and related messages e.g., cancellations, etc. are processed in the order in which they are received by the ATS.

Match Priority

Orders are time-stamped to the millisecond by the ATS upon receipt, as are cancel/replaces. Orders are matched by the ATS on a price/time priority basis.

The orders of a Subscriber that enters both buy and sell orders in the same NMS Stock into the ATS are matched against each other, but only if there is not an existing order on the order book at the same or a better price. For example, assume the ATS receives the following orders:

- ORDER A: tagged with identifier CLIENT1, a LIMIT DAY buy order to buy 500 shares of ABC @ $15.10 at 11:00 p.m.;

- ORDER B: tagged with identifier CLIENT2, a LIMIT DAY buy order to buy 550 shares of ABC @ $15.10 at 11:01 p.m.;

- ORDER C: tagged with identifier CLIENT3, a LIMIT DAY buy order to buy 600 shares of ABC @ $15.10 at 11:02 p.m.;

- ORDER D: tagged with identifier CLIENT3, a LIMIT DAY buy order to buy 100 shares of ABC @ $15.10 at 11:03 p.m.; and

- ORDER E: tagged with identifier CLIENT3, a LIMIT DAY sell order to sell 800 shares of ABC @ $15.10 at 11:04 p.m.

Because the ATS's Operating Hours (8 p.m. ET to 4 a.m. ET) are after the Core Market Hours (9:30 a.m. ET to 4 p.m. ET, Monday through Friday), trades executed on the ATS are not priced according to, and do not relate to the NBBO, which is not available during the Operating Hours.

All orders entered into BOATS are considered firm orders. An order is actionable and eligible for execution at any time until such order has expired by its terms, is canceled, or is executed and, when executed, is binding on the Subscriber placing the order. Subscribers may cancel their pending orders at any time before execution at their discretion.

A reduction in an order's size through a cancel/replace instruction does not affect the order's original time priority. Changes that increase an orders size cause the order to lose priority to existing orders at the same price and result in a new time priority. A change in an order's price, however, results in a new time priority being assigned to the order.

Orders are rejected if they contain instructions or order attributes that are not supported by the ATS, such as an invalid stock symbol. Subscribers are also subject to pre-trade credit and risk controls to prevent certain orders from reaching the ATS. Each Subscriber is subject to a daily notional value limit, a maximum notional value per order, a maximum quantity per order, a maximum number of orders per second, and a maximum number of duplicate orders (same ticker symbol, size, side, order type and price). The CCO or his or her designee determines the limits for each Subscriber based on a credit risk assessment before the Subscriber is permitted to commence trading on the ATS. These controls reject Subscriber orders that exceed pre-set credit thresholds or that contain a sub- penny price, among others.

      <taPart3Item10aOpenReOpenDtls>On the days of operation, Subscribers may submit test orders to the ATS at 6:15 p.m. ET, and bona-fide orders are accepted at 8:00 p.m. ET. Matching occurs on a price-time priority basis during BOATS operating hours from 8:00 p.m. ET to 4:00 a.m. ET

BOATS begins matching orders, based on the terms of the orders in its order book, at 8:00 p.m. ET.

BOATS employs a 20% price band during its trading session. Orders entered into the ATS prior to the beginning of, and during the trading session that are priced at more than 20% away from the reference price for that NMS Stock, the ATS rejects the order. 
Orders are prioritized based on the price and time of entry of such orders into the ATS. Once an order has been submitted, the ATS matches it with a matching contra order submitted to the ATS, generally on a price/time priority basis.

Because the ATS does not operate during Core Market Hours, it is not impacted by trading halts in an NMS Stock during Core Market Hours. If trading in an NMS Stock that trades on BOATS is halted as of the close of the exchange trading day, the ATS does not trade that NMS Stock during its immediately following trading session.

If trading in an NMS Stock is halted on BOATS during the ATS's trading session, the ATS notifies its Subscribers of the halt. The ATS cancels all orders for the effected NMS Stock pending on the ATS's order book at the time the ATS halts trading. Such orders are automatically cancelled based on a configuration in Subscribers' FIX connections. Once the ATS lifts the halt, BOATS sends a notification to Subscribers that trading is once again available on the ATS and that they may enter orders. Those orders are matched based on the price/time priority rules of BOATS.</taPart3Item10aOpenReOpenDtls>

      <taPart3Item10cUnexeOrdrTIDtls>All orders on the ATS order book are canceled at the end the trading session. Thus, there are no unexecuted orders from the close of the ATS's prior trading session when BOATS begins its regular trading at 8:00 p.m. ET.
Because BOATS does not operate during Core Market Hours, exchange trading halts do not impact trading on the ATS unless such a trading halt remains in effect upon the close of Core Market Hours. If trading in a particular NMS stock is halted on an exchange as of the close of trading, the ATS does not trade that NMS Stock during its immediately following overnight trading session, as discussed in Part III, Item 7.

If trading in an NMS Stock is halted on BOATS during its Operating Hours, the ATS notifies its Subscribers of the halt. The ATS cancels all orders for the effected NMS Stock pending on the ATS's order book at the time the ATS halts trading.

      <taPart3Item11aStrucOfNmsStk>BOATS operates a fully automated electronic limit order book that continuously matches orders to buy or sell NMS Stocks. All NMS stocks are eligible to trade on the ATS, unless otherwise notified on the Blue Ocean ATS website, https://blueocean-tech.io/blue-ocean-ats-service-status/. All orders submitted to the ATS are firm, and are eligible for automatic execution by the system, consistent with the instructions and conditions indicated on the order as submitted by Subscribers. Matching occurs on a price-time priority basis. BOATS operating hours are 8:00 p.m. ET to 4:00 a.m. ET, as discussed in Part III, Item 4(a).

Subscribers generate orders in securities eligible for trading on the ATS and send these orders electronically to the BOATS FIX order gateway ("Gateway"). The Gateway directs all orders to the BOATS matching engine. The BOATS matching engine operates on a server in Equinix NY4 data center. Equinix maintains the server in a locked "cage" that is accessible only by such personnel as indicated in Part II, Item 7.

The MEMX licensing agreement is with BOT. BOT then provides all technology or software, including technology from MEMX, used to operate the ATS to BOATS, including the matching engine. Shared employees of the parent company and BDO, as outlined in Part II, Item 6(a), work with MEMX technology and operations personnel to maintain these systems, pursuant to the licensing agreement.  </taPart3Item11aStrucOfNmsStk>

      <taPart3Item11cRulsProcsOfNmsStk>Matching - The ATS accepts only orders from Subscribers. The ATS matches orders solely in accordance with the terms of those orders; BOATS does not have any discretion to change the terms of an order that a Subscriber enters. During its Operating Hours, the ATS matches orders in its order book on price-time priority basis. Orders retain their priority after partial fills. Orders submitted to the ATS are time-stamped to the millisecond upon receipt for prioritization purposes and for OATS and CAT reporting purposes.

For example:

ORDER A: tagged with identifier CLIENT1, a LIMIT DAY buy order to buy 500 shares of ABC @ $10 is entered in the system at 11:00 p.m.;

ORDER B: tagged with identifier CLIENT2, a LIMIT DAY sell order to sell 500 shares of ABC @ $11 is entered in the system at 11:01 p.m.;

ORDER C: tagged with identifier CLIENT3, a LIMIT DAY sell order to sell 1000 shares of ABC @ $10 is entered in the system at 11:02 p.m.;

ORDER C is immediately executed (matched with a contra interest) for 500 shares of ABC @ $10 at 11:02 p.m. against resting ORDER A;

The remaining (unexecuted) 500 shares of ORDER C remain on the ATS offered @ $10 at 11:02 p.m., and ORDER B's sell order to sell 500 shares of ABC @ $11 remains on the ATS at 11:02 p.m.;

Both ORDER C and ORDER B are resting orders on the ATS at 11:02 p.m.

Locked or Crossed Markets - All orders entered during the Operating Hours reside only on the BOATS order book. A buy order priced at or above the best offer, or sell order priced at or below the best bid, therefore result in executions, not locked or crossed markets.

For example:

ORDER A: tagged with identifier CLIENT1, a LIMIT DAY buy order to buy 500 shares of ABC @ $10 is entered in the system at 11:00 p.m.;

ORDER B: tagged with identifier CLIENT2, a LIMIT DAY sell order to sell 500 shares of ABC @ $11 is entered in the system at 11:01 p.m.;

ORDER C: tagged with identifier CLIENT3, a LIMIT DAY sell order to sell 1000 shares of ABC @ $9 is entered in the system at 11:02 p.m.;

ORDER C is immediately executed (matched with a contra interest) for 500 shares of ABC @ $10 at 11:02 p.m. against resting ORDER A;

The remaining (unexecuted) 500 shares of ORDER C remain on the ATS offered @ $9 at 11:02 p.m., and ORDER B's sell order to sell 500 shares of ABC @ $11 remains on the ATS at 11:02 p.m.;

Both ORDER C and ORDER B are resting orders on the ATS at 11:02 p.m.

The reference price for the trading session is the last national securities exchange print, post session, as of 7:30 p.m. ET.

Execution Errors - Blue Ocean ATS, LLC has written supervisory policies and procedures in place to handle trade execution errors and "clearly erroneous trades" and handles Subscriber and ATS errors in the same manner. Each potential error situation is evaluated by the Managing Director and/or CCO or designated Trading Operations personnel on a case-by-case basis to determine whether a trade execution should be busted. A transaction executed on the ATS shall be found to be clearly erroneous if the price of the transaction to buy (sell) that is the subject of the inquiry is greater than (less than) the reference price by 26% for NMS Stocks priced greater than $50; 30% for NMS Stocks priced greater than $25 and up to and including $50; and 40% for NMS Stocks priced greater than $0 and up to and including $25. The reference price for the clearly erroneous policy is the most recent transaction effected on the ATS.

Order Entry Restrictions - The ATS does not accept orders that reference a symbol not authorized for trading (e.g., if there is a trading halt). Consistent with Rule 612 of Regulation NMS under the Exchange Act, the minimum price increment for orders received by the ATS shall be $0.01 for orders priced $1.00 or greater, and
$0.0001 for orders priced below $1.00. Orders received with price increments below the preceding are rejected. Sell orders must be designated as long, short or short exempt in the event there is a short sale restriction in place. Subscribers are responsible for the compliance of their trades with all short sale locate and delivery rules and regulations.

BOATS also reserves the right to suspend trading in NMS Stocks at their own discretion, including for reasons including SSR restrictions, or approaching fair access or Reg SCI thresholds. When BOATS suspends trading in an NMS Stock, the ATS cancels all orders for the effected NMS stock in the order book and notifies subscribers. Orders are cancelled based on a configuration in FIX connection.
