I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    Cboe BYX Exchange, Inc. (the ``Exchange'' or ``BYX'') proposes to 
adopt new market data reports. The text of the proposed rule change is 
provided in Exhibit 5.
    The text of the proposed rule change is also available on the 
Exchange's website (http://markets.cboe.com/us/equities/regulation/rule_filings/byx/), at the Exchange's Office of the Secretary, and at 
the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant aspects of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to amend Rule 11.22 (Data Products) to adopt 
the Cboe Timestamping Service, which is a market data service comprised 
of two distinct market data reports. The Cboe Timestamping Service will 
provide timestamp information for orders and cancels for market 
participants. More specifically, the Cboe Timestamping Service reports 
will provide various timestamps relating to the message lifecycle 
throughout the exchange system. The first report--the Missed Liquidity 
Report--will cover order messages and the second report--Cancels 
Report--will cover cancel messages. The proposed reports are optional 
products that will be available to all Members and Members may opt to 
choose both reports, one report, or neither report. Corresponding fees 
will be assessed based on the number of reports selected.\5\
---------------------------------------------------------------------------

    \5\ The Exchange plans to submit a separate filing with the 
Commission pursuant to Section 19(b)(1) to propose fees for the 
Missed Liquidity Report and Cancels Report.
---------------------------------------------------------------------------

    The Exchange notes that the data included in the proposed reports 
will be based only on the data of the market participant that opts to 
subscribe to the reports (``Recipient Member'') and will not include 
information related to any Member other than the Recipient Member. The 
Exchange will restrict all other market participants from receiving 
another market participant's data. Additionally, neither report 
includes real-time market data. Rather, the reports will contain 
historical data from the prior trading day and will be available after 
the end of the trading day, generally on a T+1 basis.
    Currently, the Exchange provides real-time prices and analytics in 
the marketplace. The Exchange proposes to introduce the Missed 
Liquidity and Cancel Reports in response to Member demand for 
additional data concerning the timeliness of their incoming orders, 
cancel messages and executions against resting orders. Members have 
frequently requested from the Exchange's trading operations personnel 
information concerning the timeliness of their incoming orders, cancel 
messages and efficacy of their attempts to execute against resting 
liquidity on the Exchange's Book. The Exchange believes the additional 
data points outlined below may help Members gain a better understanding 
about their interactions with the Exchange. The Exchange believes these 
reports will provide Members with an opportunity to learn more about 
better opportunities to access liquidity and receive better execution 
rates and improve order cancel success. The proposed reports will also 
increase transparency and democratize information so that all Members 
that subscribe to either or both reports have access to the same 
information on an equal basis.
    The proposed Missed Liquidity Report will provide time details for 
executions of orders that rest on the book where the Member receiving 
the report attempted to execute against that resting order within an 
Exchange-determined amount of time (not to exceed 1 millisecond) after 
receipt of the first attempt to execute against the resting order and 
within an Exchange-determined amount of time (not to exceed 100 
microseconds) before receipt of the first attempt to execute against 
the resting order.\6\ For example, if a Member sends in a marketable 
order, but an order resting on the Exchange order book was subsequently 
executed, the Missed Liquidity Report can assist the Member in 
determining by how much time that order missed an execution.\7\
---------------------------------------------------------------------------

    \6\ The Exchange will announce the Exchange-determined 
timeframes with reasonable advance notice via Exchange Notice.
    \7\ For example, Participant A submits an order that is posted 
to the Exchange's Book. Participant B at some point thereafter 
enters a marketable order to execute against Participant A's resting 
order. Within 500 microseconds of Participant B's submission, 
Participant C, also sends a marketable order to execute against 
Participant A's resting order. Because Participant B's order is 
received by the Exchange before Participant C's order, Participant 
B's order executes against Participant A's resting order. The 
proposed Report would provide Participant C (the Recipient Member of 
the report) the data points necessary for that firm to calculate by 
how much time they missed executing against Participant A's resting 
order.

---------------------------------------------------------------------------

[[Page 68661]]

    The Cancels Report will provide liquidity response time details for 
orders that rest on the book where the Member receiving the report 
attempted to cancel that resting order or any other resting order 
within an Exchange-determined amount of time (not to exceed 1 
millisecond) after receipt of the order that executed against the 
resting order and within an Exchange-determined amount of time (not to 
exceed 100 microseconds) before receipt of the order that executed 
against the resting order.\8\ For example, if a market participant 
sends in a cancel message, but an order resting on the Exchange order 
book was executed prior to the system processing the cancel message, 
the Cancel report can assist the market participant in determining by 
how much time that order missed being canceled instead of executing.\9\
---------------------------------------------------------------------------

    \8\ The Exchange will announce the Exchange-determined 
timeframes with reasonable advance notice via Exchange Notice.
    \9\ For example, Participant A submits an order that is posted 
to the Exchange's Book and Participant B at some point thereafter 
submits a marketable order to execute against Participant A's 
resting order. Within 500 microseconds of submission of Participant 
B's order, Participant A sends a cancel message to cancel its 
resting order. Because Participant B's order is processed at the 
Matching Engine by the Exchange before Participant A's cancel 
message, Participant B's order executes against Participant A's 
resting order. The proposed Report would provide Participant A the 
data points necessary for that firm to calculate by how much time 
they missed canceling its resting order.
---------------------------------------------------------------------------

    Both the Missed Liquidity Report and Cancels Report will include 
the following data elements for orders \10\ and cancel messages,\11\ 
respectively: (1) Recipient Member Firm ID; (2) Symbol; (3) Execution 
ID; \12\ (3) Exchange System Timestamps for orders and cancels; \13\ 
(4) Matching Unit number; \14\ (5) Queued; \15\ (6) Port Type; \16\ and 
(7) Aggressor Order Type.\17\ No specific information about resting 
orders on the Exchange book will be provided.
---------------------------------------------------------------------------

    \10\ The Missed Liquidity Report will only include trade events 
which are triggered by an order that removed liquidity on entry and 
will exclude trade events resulting from: elected stop orders, 
orders routed and executed at away venues, and peg order movements, 
and auctions.
    \11\ Includes individual order cancellations, mass cancels, and 
purge orders messages that are sent via Financial Information 
Exchange (``FIX'') protocol or Binary Order Entry (BOE) protocol by 
a subscriber.
    \12\ The Execution ID is a unique reference number assigned by 
the Exchange for each trade.
    \13\ Includes Network Discovery Time (which is a network 
hardware switch timestamp taken at the network capture point); Order 
Handler NIC Timestamp (which is a hardware timestamp that represents 
when a BOE order handler server NIC observed the message); Order 
Handler Received Timestamp (which is software timestamp that 
represents when the FIX or BOE order handler has begun processing 
the order after the socket read); Order Handler Send Timestamp 
(which represents when the FIX or BOE order handler has finished 
processing the order and begun sending to the matching engine); 
Matching Engine NIC Timestamp (which is a hardware timestamp that 
represents when the target matching engine server NIC observed the 
message); and Matching Engine Transaction Timestamp (which is a 
software timestamp that represents when the matching engine has 
started processing an event).
    \14\ Represents the matching unit number.
    \15\ Flag to indicate whether a message was delayed due to 
message in flight limits (i.e., a limit on the total number of 
messages in flight between an order handler and a matching engine).
    \16\ Refers to the port type used by the session to send the 
applicable message.
    \17\ Indicates whether the order type of the response order that 
executed against the resting order was a new order or modify 
message.
---------------------------------------------------------------------------

    Market participants generally would use liquidity accessing orders 
if there is a high probability that it will execute an order resting on 
the Exchange order book. As noted above, the Missed Liquidity Report 
helps subscribing market participants to better understand by how much 
time they missed executing against certain resting orders. The Exchange 
therefore believes this report will provide greater visibility into 
what was missed in trading so market participants can better determine 
whether they want to invest in the technology to mitigate the misses. 
It may also allow for them to optimize their models and trading 
patterns to yield better execution results. Similarly, the Cancels 
Report will provide information that helps subscribing market 
participants determine how best to improve success rates with respect 
to canceling their orders, which reduces exposure and manages risk.
    The Exchange notes the data information contained within the 
proposed Missed Opportunities Report and Cancels Report are similar to 
data provided in reports that currently are, or historically have been, 
offered by other exchanges.\18\
---------------------------------------------------------------------------

    \18\ The proposed Report is based on a similar report previously 
provided by the NASDAQ Stock Market LLC (``NASDAQ'') for equity 
securities called the Missed Opportunity--Latency report as part of 
its NASDAQ Trader Insights offering. See Securities Exchange Act 
Release No. 78886 (September 20, 2016), 81 FR 66113 (September 26, 
2016) (SR-NASDAQ-2016-101) (Order Granting Approval of Proposed Rule 
Change, as Modified by Amendment Nos. 1 and 2, To Add NASDAQ Rule 
7046 (Nasdaq Trading Insights)) (``NASDAQ Approval Order''). The 
report is also similar to a report currently provided by MIAX 
Emerald, LLC (``MIAX Emerald'') and its affiliates, called the 
Liquidity Taker Event Report. See e.g., MIAX Emerald Rule 531. See 
also Securities Exchange Act Release No. 91356 (March 18, 2021), 86 
FR 15759 (March 24, 2021) (SR-EMERALD-2021-09).
---------------------------------------------------------------------------

Implementation
    The Exchange will announce via Exchange Notice the implementation 
date of the proposed rule change, which shall occur no later than 60 
days after the operative date of this rule filing.
2. Statutory Basis
    The Exchange believes that the proposed Cboe One Options Feed [sic] 
is consistent with Section 6(b) of the Act,\19\ in general, and 
furthers the objectives of Section 6(b)(5) of the Act,\20\ in 
particular, in that it is 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 to protect 
investors and the public interest, and that it is not designed to 
permit unfair discrimination among customers, brokers, or dealers. The 
Exchange also believes this proposal is consistent with Section 6(b)(5) 
of the Act because it protects investors and the public interest and 
promotes just and equitable principles of trade by providing investors 
with new options for receiving market data as requested by market 
participants and Section 6(b)(8) of the Act, which requires that the 
rules of an exchange not impose any burden on competition that is not 
necessary or appropriate in furtherance of the purposes of the Act.\21\ 
This proposal is in keeping with those principles in that it promotes 
increased transparency through the dissemination of the optional Missed 
Liquidity and Cancels Report to those interested in paying to receive 
either or both of these reports.
---------------------------------------------------------------------------

    \19\ 15 U.S.C. 78f.
    \20\ 15 U.S.C. 78f(b)(5).
    \21\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

    The Exchange also believes this proposal is consistent with Section 
6(b)(5) of the Act because it protects investors and the public 
interest and promotes just and equitable principles of trade by 
providing investors with new options for receiving market data as 
requested by potential purchasers. The proposed rule change would 
benefit investors by facilitating their prompt access to the value-
added information that is included in the proposed reports. The reports 
will allow Members to access information regarding their trading 
activity that they may utilize to evaluate their own trading behavior 
and order interactions. It also promotes just and equitable principles 
of trade because it would provide latency information in a systematized 
way and standardized format to any Member that chooses to subscribe to 
the proposed reports. As discussed, the proposed reports are also not 
real-time market data products, but rather provide only historical 
trading data for the previous trading day, generally on a T+1 basis. In 
addition, the data in the reports

[[Page 68662]]

regarding incoming orders that failed to execute or incoming cancels 
that failed to cancel would be specific to the Recipient Member's 
messages. As noted above, no specific information about the resting 
orders on the Exchange book will be provided and any information 
relating to another Member would be anonymized.
    In adopting Regulation NMS, the Commission granted self-regulatory 
organizations (``SROs'') and broker dealers increased authority and 
flexibility to offer new and unique market data to consumers of such 
data. It was believed that this authority would expand the amount of 
data available to users and consumers of such data and also spur 
innovation and competition for the provision of market data. The 
Exchange believes that the proposed reports are the sort of market data 
product that the Commission envisioned when it adopted Regulation NMS.
    The Commission concluded that Regulation NMS--by deregulating the 
market in proprietary data--would itself further the Act's goals of 
facilitating efficiency and competition:
    ``[E]fficiency is promoted when broker-dealers who do not need the 
data beyond the prices, sizes, market center identifications of the 
NBBO and consolidated last sale information are not required to receive 
(and pay for) such data. The Commission also believes that efficiency 
is promoted when broker-dealers may choose to receive (and pay for) 
additional market data based on their own internal analysis of the need 
for such data.'' \22\
---------------------------------------------------------------------------

    \22\ See Securities Exchange Act Release No. 51808 (June 9, 
2005), 70 FR 37496 (June 29, 2005) (``Regulation NMS Adopting 
Release'').
---------------------------------------------------------------------------

    By removing ``unnecessary regulatory restrictions'' on the ability 
of exchanges to sell their own data, Regulation NMS advanced the goals 
of the Act and the principles reflected in its legislative history. 
This proposed Cboe Timestamping Service (i.e., the Missed Liquidity and 
Cancels Reports) provides investors with new options for receiving 
market data, which was a primary goal of the market data amendments 
adopted by Regulation NMS.\23\
---------------------------------------------------------------------------

    \23\ See Regulation NMS Adopting Release, supra, at 37503.
---------------------------------------------------------------------------

    The proposed reports are designed for Members that are interested 
in gaining insight into latency in connection with their respective (1) 
orders that failed to execute against an order resting on the Exchange 
order book and/or (2) cancel messages that failed to cancel resting 
orders. The Exchange believes that providing this optional data to 
interested market participants for a fee is consistent with 
facilitating transactions in securities, removing impediments to and 
perfecting the mechanism of a free and open market and a national 
market system, and, in general, protecting investors and the public 
interest because it provides additional information and insight to 
subscribing market participants regarding their trading activity on the 
Exchange. More specifically, the proposed reports provide greater 
visibility into exactly what was missed in trading so market 
participants may optimize their models and trading patterns to yield 
better execution results by identifying by how much time an order that 
may have been marketable missed executing and by how much time a cancel 
message missed canceling.
    As mentioned above, other exchanges currently offer, or have 
previously offered, similar trading related reports that have been 
reviewed and approved by the Commission.\24\ For example, MIAX Emerald 
currently offers the Liquidity Taker Event Report and Nasdaq 
historically provided the Missed Opportunity--Latency report as part of 
its NASDAQ Trader Insights offering.\25\ MIAX Emerald's Liquidity Taker 
Event Report and Nasdaq's prior Missed Opportunity--Latency report, 
like the proposed Missed Liquidity Report, identify by how much time an 
order missed executing against a resting order. Also, like the MIAX 
Emerald and Nasdaq's analogous reports, the Exchange's proposed reports 
are provided on a T+1 basis and include data specific to one Member, 
and only that Member would receive the report. The proposed reports, 
like the reports of MIAX Emerald and Nasdaq, restrict all other market 
participants, including the Recipient Member, from receiving another 
market participant's data. In addition, the proposed reports, like the 
MIAX Emerald and Nasdaq reports, are each intended to provide the 
Recipient Member with the time duration by which the order entered by 
the Recipient Member missed an execution or similarly, missed canceling 
an order before it could execute.\26\ The proposed reports, along with 
the MIAX Emerald Liquidity Taker Event Report and/or Nasdaq Missed 
Opportunities--Latency reports, each include the following information:
---------------------------------------------------------------------------

    \24\ Supra Note 18.
    \25\ The Exchange notes that like Nasdaq's Missed Opportunity--
Latency report, the proposed reports cover equity securities, 
whereas the MIAX Emerald Liquidity Taker Event Report covers options 
trading. The Exchange believes this difference is of no consequence 
as each of these reports are intended to serve the same purpose--
providing firms with an opportunity to learn more about when they 
may have better opportunities to access liquidity and to receive 
better execution rates or cancel success.
    \26\ Although not clearly defined, the Exchange believes that 
MIAX Emerald's Liquidity Taker Event Report also provides 
information relating to cancel messages. Particularly, MIAX Emerald 
Liquidity Taker Event Report provides, among other things, data 
relating to the ``type of each response submitted by the Recipient 
Member.'' See MIAX Emerald Rule 5.31(a)(iii)(C). MIAX Emerald's 
technical specifications outline the various types of available 
liquidity messages including, Simple Mass Quote Cancel Request and 
Mass Liquidity Cancel Request See MIAX Express Interface for Quoting 
and Trading Options, MEI Interface Specification, Section 4.1 
(Liquidity Messages), available at: 
MIAX_Express_Interface_MEI_v2.2a.pdf (miaxglobal.com). The Exchange 
also believes that providing the same data points for cancel 
messages as the data provided for orders messages is of no materials 
consequence as the Cancels Report is intended to serve a similar 
purpose as the proposed Missed Liquidity Report--providing Members 
additional information to better understand the efficacy of their 
incoming orders and cancel messages.

 Recipient Member identifier
 Symbol
 Execution ID
 Order reference number (unique reference number assigned to a 
new order at the time of receipt)
 Exchange System Timestamps for incoming orders and cancels, 
including timestamps to determine the time difference between the time 
the first response that executes against the resting order was received 
by the Exchange and the time of each response sent by the Recipient 
Member, regardless of whether it executed or not
 The order type of the response that executes against the 
resting order

    The proposed reports include the following information that are/
were not included in either the MIAX Emerald Liquidity Taker Event 
Report and/or Nasdaq Missed Opportunities--Latency Report:

 Matching Unit Number. This information is specific to the 
Exchange's matching unit architecture
 Queued. This information indicates whether or not a message 
was delayed due to message in flight limits, which limits are specific 
to the Exchange only
 The port type

    Lastly, the proposed reports do not include the following 
information that is/was included in both the MIAX Emerald Liquidity 
Taker Event Report and Nasdaq Missed Opportunities--Latency Report:

 Side (buy or sell). This information is already available via 
OPRA or the Exchange's proprietary data feeds
 Displayed price and size. This information is already 
available via

[[Page 68663]]

OPRA or the Exchange's proprietary data feeds
 The time a resting order was received by the Exchange. The 
Exchange does not believe information relating to the time a resting 
order was received is as relevant as the above-described data that will 
be included nor is it necessary with respect to the goal of the 
proposed reports which is to better understand by how much time a 
particular order missed executing against an order resting on the Book 
or a cancel message missed canceling against an order resting on the 
Book.

    As illustrated above, the proposed reports are substantially 
similar to the MIAX Emerald Liquidity Taker Event Report and Nasdaq's 
former Missed Opportunities--Latency Report and includes a number of 
the same data elements designed to assist Members in better 
understanding their trading activity on the Exchange and augment their 
trading strategies to improve their execution opportunities.
    In approving Nasdaq's Missed Opportunity--Latency report, the 
Commission noted that the report ``would increase transparency, 
particularly for Members who may not have the expertise to generate the 
same information.'' \27\ The Exchange's proposed reports would achieve 
the same goal for Members seeking to better understand the efficacy of 
their incoming orders and cancel messages. Further, the proposed 
reports promote just and equitable principles of trade because it will 
increase transparency and democratize information so that all firms may 
elect to subscribe to either, or both, reports even though some firms 
may not have the appropriate resources to generate a similar report 
themselves.
---------------------------------------------------------------------------

    \27\ See Securities Exchange Act Release No. 78886 (September 
20, 2016), 81 FR 66113 (September 26, 2016) (SR-NASDAQ-2016-101) 
(Order Granting Approval of Proposed Rule Change, as Modified by 
Amendment Nos. 1 and 2, To Add NASDAQ Rule 7046 (Nasdaq Trading 
Insights)) (``NASDAQ Approval Order'').
---------------------------------------------------------------------------

    The Exchange proposes to provide the reports on a voluntary basis 
and no Member will be required to subscribe to either report. The 
Exchange notes that there is no rule or regulation that requires the 
Exchange to produce, or that a Member elect to receive, either report. 
It is entirely a business decision of each Member to subscribe to one, 
both, or neither report. The Exchange proposes to offer the reports as 
a convenience to Members to provide them with additional information 
regarding trading activity on the Exchange on a delayed basis after the 
close of regular trading hours. A Member that chooses to subscribe to 
the reports may discontinue receiving either report at any time if that 
Member determines that the information contained in the Report is no 
longer useful.
    In summary, the proposed reports will help to protect a free and 
open market by providing additional historical data (offered on an 
optional basis) to the marketplace and by providing investors with 
greater choices. Additionally, the proposal would not permit unfair 
discrimination because the proposed reports will be available to all 
Exchange Members.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. Rather, the Exchange 
believes that the proposed Report will enhance competition by providing 
a new option for receiving market data to Members. The proposed Report 
will also further enhance competition between exchanges by allowing the 
Exchange to expand its product offerings to include reports similar to 
a report that is currently offered by other exchanges.\28\
---------------------------------------------------------------------------

    \28\ See e.g., MIAX Emerald Rule 531.
---------------------------------------------------------------------------

    Additionally, the Exchange believes the proposed rule change does 
not impose any burden on intramarket competition that is not necessary 
or appropriate in furtherance of the purposes of the Act. Market 
participants are not required to purchase either proposed report, and 
the Exchange is not required to make either report available to 
investors. Rather, the Exchange is voluntarily making these reports 
available, as requested by Members, and Members may choose to receive 
(and pay for) this data based on their own business needs. Potential 
purchasers may request the data at any time if they believe it to be 
valuable or may decline to purchase such data.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange neither solicited nor received comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the foregoing proposed rule change does not:
    A. significantly affect the protection of investors or the public 
interest;
    B. impose any significant burden on competition; and
    C. become operative for 30 days from the date on which it was 
filed, or such shorter time as the Commission may designate, it has 
become effective pursuant to Section 19(b)(3)(A) of the Act \29\ and 
Rule 19b-4(f)(6) \30\ thereunder. At any time within 60 days of the 
filing of the proposed rule change, the Commission summarily may 
temporarily suspend such rule change if it appears to the Commission 
that such action is necessary or appropriate in the public interest, 
for the protection of investors, or otherwise in furtherance of the 
purposes of the Act. If the Commission takes such action, the 
Commission will institute proceedings to determine whether the proposed 
rule change should be approved or disapproved.
