On March 5, 2021, MIAX EMERALD, LLC (“MIAX Emerald” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
and Rule 19b-4 thereunder,
a proposed rule change to adopt Exchange Rule (“Rule”) 531(a) to provide for a new “Liquidity Taker Event Report” (“Report”). The proposed rule change was published for comment in the Federal Register on March 24, 2021.
The Commission has received no comments on the proposed rule change. This order approves the proposed rule change.
II. Description of the Proposed Rule Change
The Report that the Exchange proposes to offer pursuant to new Rule 531(a) would be an historical options data product, generally available on a T+1 basis, that would provide certain information from the prior trading day to any member that wishes to subscribe to the Report.
The information set forth in the proposed Report would be designed to identify for any subscribing member (“Recipient Member”) the amount of time by which certain orders from the Recipient Member that may have been marketable missed an execution due to other liquidity-accessing orders responding faster to resting interest on the Exchange's book.
Specifically, for instances during the prior trading day where a Recipient Member attempted to execute against a resting order within 200 microseconds of the Exchange's receipt of the resting order, the proposed Report would provide time-related information and additional detail regarding the resting order, the first response to the resting order that successfully executed against the resting order, and the Recipient Member's responses that missed executing against the resting order.
Proposed Rule 531(a)(1) describes this time-related information and additional detail. With regard to each resting order covered by the proposed Report, the proposed Report would provide: (A) The time the resting order was received by the Exchange; 
(B) symbol; (C) order reference number, which is a unique reference number assigned to a new order at the time of receipt; (D) whether the Recipient Member is an affiliate of the member that entered the resting order; 
(E) origin type (e.g., priority customer, market maker); (F) side (buy or sell); and (G) displayed price and size of the resting order.
With regard to the execution of the resting order, the proposed Report would provide: (A) The EBBO at the time of execution; 
(B) the ABBO at the time of execution; 
(C) the time the first response that executed against the resting order was received by the Exchange and the size of the execution and type of the response; 
(D) the time difference between when the resting order was received by the Exchange and when the first response that executed against the resting order was received by the Exchange; 
and (E) whether the response was entered by the Recipient Member.
With regard to response(s) sent by the Recipient Member, the proposed Report would provide: (A) A Recipient Member identifier; (B) the time difference between when the first response that executes against the resting order was received by the Exchange and when each response sent by the Recipient Member was received by the Exchange, regardless of whether the Recipient Member's responses executed or not; 
(C) size and type of each response submitted by the Recipient Member; and (D) response reference number, which is a unique reference number attached to the response by the Recipient Member.
In addition, proposed Rule 531(a)(3) would state that the Report would only include trading data related to the Recipient Member, and would not include any other member's trading data other than that listed in paragraphs (1)(i) and (ii) of the proposed rule.
Further, the Exchange states that the content of the Report would be specific and tailored to the Recipient Member, and any data included in the Report that relates to a member other than the Recipient Member would be anonymized.
According to the Exchange, the proposed Report is designed for members that are interested in gaining insight into latency in connection with orders that failed to execute against an order resting on the Exchange's book.
Exchange members have periodically requested from the Exchange's trading Start Printed Page 26112operations personnel information concerning the timeliness of their incoming orders and efficacy of their attempts to execute against resting liquidity.
The Exchange states that the purpose of the proposed Report is to provide Recipient Members with this type of data in a standardized format and on an equal basis.
The Exchange believes that Recipient Members may use the data to optimize their models and trading patterns in an effort to yield better execution results.
In addition, the Exchange states that the proposed Report is based on a similar data product that another exchange offers for equity securities,
and that certain information that would be provided in the proposed Report, including in particular the time duration by which a Recipient Member's orders missed an execution, is similar to information that is provided in the other exchange's data product.
Moreover, according to the Exchange, other information that would be contained in the proposed Report already is available from existing data sources, such as OPRA and the Exchange's proprietary data feeds, or is information that the Exchange would provide as a convenience to the Recipient Member and that would be known to the Recipient Member even if not included in the Report.
III. Discussion and Commission Findings
After careful review, the Commission finds that the proposed rule change is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.
In particular, the Commission finds that the proposal is consistent with Section 6(b)(5) of the Act,
which requires, among other things, that the rules of a national securities exchange be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest, and that those rules not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers.
As discussed above, the Exchange currently fields ad hoc requests from members for information regarding the timeliness of their attempts to execute against resting options liquidity on the Exchange's book.
The proposal is designed to offer this type of latency information in a systematized way and standardized format to any member that chooses to subscribe to the Report. As a result, the Commission believes that the proposal will make latency information for liquidity-seeking orders available to Exchanges members in a more equalized manner and will increase transparency, particularly for Recipient Members that may not have the expertise to generate the same information on their own. The Commission also believes that the proposed Report may better enable Recipient Members to increase the fill rates for their liquidity-seeking orders. At the same time, as is also discussed above, the Report is designed to prevent a Recipient Member from learning other members' sensitive trading information. The Report would not be a real-time market data product, as it would provide only historical trading data for the previous trading day, generally on a T+1 basis.
In addition, the data in the Report regarding incoming orders that failed to execute would be specific to the Recipient Member's orders,
and other information in the proposed Report regarding resting orders and executions would be anonymized if it relates to a member other than the Recipient Member.
Accordingly, consistent with Section 6(b)(5) of the Act, the Commission believes that the proposal is designed to prevent fraudulent and manipulative acts and practices, promote just and equitable principles of trade, remove impediments to and perfect the mechanism of a free and open market and a national market system, and protect investors and the public interest, and is not designed to permit unfair discrimination.
It is therefore ordered, pursuant to Section 19(b)(2) of the Act,
that the proposed rule change (SR-EMERALD-2021-09), be, and hereby is, approved.
For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.
