SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-103721; File No. SR-CboeEDGX-2025-067]


Self-Regulatory Organizations; Cboe EDGX Exchange, Inc.; Notice 
of Filing and Immediate Effectiveness of a Proposed Rule Change To 
Amend Rule 21.15(b) (Exchange Data Products) To Adopt a New Market Data 
Report

August 15, 2025.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on August 5, 2025, Cboe EDGX Exchange, Inc. (the ``Exchange'' or 
``EDGX'') filed with the Securities and Exchange Commission (the 
``Commission'') the proposed rule change as described in Items I and II 
below, which Items have been prepared by the Exchange. The Exchange 
filed the proposal as a ``non-controversial'' proposed rule change 
pursuant to Section 19(b)(3)(A)(iii) of the Act \3\ and Rule 19b-
4(f)(6) thereunder.\4\ The Commission is publishing this notice to 
solicit comments on the proposed rule change from interested persons.

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

    Cboe EDGX Exchange, Inc. (the ``Exchange'' or ``EDGX'') proposes to 
amend Rule 21.15(b) (Exchange Data Products) to adopt a new market data 
report. 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 (<a href="http://markets.cboe.com/us/options/regulation/rule_filings/edgx/">http://markets.cboe.com/us/options/regulation/rule_filings/edgx/</a>) and at the Exchange's Office of the Secretary.

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 21.15(b) (Exchange Data 
Products) to adopt an additional report as part of the existing Cboe 
Timestamping Service reports. The Cboe Timestamping Service reports 
provide timestamp information for orders, quotes and cancels for 
Members. More specifically, the Cboe Timestamping Service reports 
provide various timestamps relating to the message lifecycle throughout 
the exchange system. The first report that is currently offered--the 
Missed Liquidity Report--covers order and quote messages and the second 
report--Cancels Report \5\--covers cancel messages.
---------------------------------------------------------------------------

    \5\ In connection with the offering of this new report, the 
Exchange proposes to modify the title of the current Cancels Report 
to Missed Cancels Report in order to provide clarity between the 
existing Cancels Report, and the new proposed All Cancels Report.

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

[[Page 40675]]

    The Exchange now proposes to introduce the All Cancel Report which 
is intended to supplement the existing Missed Cancels Report \6\ by 
offering a comprehensive view of cancel behavior and messaging 
activity. In comparison to the existing Missed Cancels Report, the All 
Cancels Report will include all cancel-related messages sent by the 
Recipient Firm (as defined below), irrespective of whether the cancel 
attempt was successful or associated with a trade event.
---------------------------------------------------------------------------

    \6\ Id.
---------------------------------------------------------------------------

    These reports are optional products that will be available to all 
Members and Members may opt to choose multiple reports, one report, or 
neither report. Corresponding fees will be assessed based on the number 
of reports selected.\7\
---------------------------------------------------------------------------

    \7\ The Exchange plans to submit a separate filing with the 
Commission pursuant to Section 19(b)(1) to propose fees for the All 
Cancels Report.
---------------------------------------------------------------------------

    The Exchange notes that the data included in the proposed report 
will be based only on the data of Member that opts to subscribe to the 
report (``Recipient Firm'') and will not include information related to 
any firm other than the Recipient Firm. The Exchange will restrict all 
other Members from receiving another Member's data. Additionally, the 
proposed report does not include real-time market data. Rather, the 
proposed report 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 the Missed Liquidity and 
Missed Cancel Reports and now proposes to introduce the All Cancels 
Report in response to demand for additional data concerning the 
timeliness of all cancel-related messages sent by the Recipient Firm, 
irrespective of whether the cancel attempt was successful or associated 
with a trade event. The Exchange believes the additional data points 
outlined below may help subscribing firms gain a better understanding 
about their interactions with the Exchange. The Exchange believes this 
report will provide subscribing firms with an opportunity to learn more 
about better opportunities to improve order cancel success. The 
proposed reports will also increase transparency and democratize 
information so that all subscribing firms that subscribe to the report 
have access to the same information on an equal basis.
    The current Missed Cancels Report provides liquidity response time 
details for orders and quotes that rest on the book where the Member 
receiving the report attempted to cancel that resting order or quote or 
any other resting order within an Exchange-determined amount of time 
(not to exceed 1 millisecond) after receipt of the order or quote that 
executed against the resting order or quote and within an Exchange-
determined amount of time (not to exceed 100 microseconds) before 
receipt of the order or quote that executed against the resting order 
or quote. For example, if a Recipient Firm 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 Missed Cancels Report can 
assist the Recipient Firm in determining by how much time that order 
missed being canceled instead of executing.\8\
---------------------------------------------------------------------------

    \8\ 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 Missed Cancels Report provides Participant A the 
data points necessary for that firm to calculate by how much time 
they missed canceling its resting order.
---------------------------------------------------------------------------

    In contrast, the proposed All Cancels Report provides a 
comprehensive view of cancel behavior and messaging activity when the 
Recipient Firm is the originator of the cancel-related message.\9\ It 
is particularly useful for analyzing cancel patterns across all market 
scenarios, including those where no trade occurred. Cancel, cancel 
rejected, or purge/mass cancel records for the subscriber are included, 
regardless of their timing or relation to a trade.
---------------------------------------------------------------------------

    \9\ The report shall not include any trade records or aggressor 
information.
---------------------------------------------------------------------------

    The All Cancels Report will include the following data elements for 
cancels: (1) Message Type; \10\ (2) Date; (3) Recipient Firm ID; (4) 
Session Sub ID; (5) Client Identifier; \11\ (6) Cboe Order ID; \12\ (7) 
Symbol; (8) Exchange System Timestamps; \13\ (9) Matching Unit number; 
\14\ (10) Queued; \15\ and (11) Port Type.\16\
---------------------------------------------------------------------------

    \10\ Represents if it was a cancel, mass cancel or purge, a 
cancel rejected, or a quote update cancel.
    \11\ The unique CIOrdID or MassCancelID assigned by the client.
    \12\ The Cboe Order ID is a unique reference number assigned by 
the Exchange.
    \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 and may not 
be available for certain reject cases); 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 and may not be available for certain reject cases); 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 and may not be available for certain reject cases); 
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.
---------------------------------------------------------------------------

    The All Cancels Report will enable subscribing market participants 
to have a deeper analysis of order management behavior across all 
market scenarios, even when no trade occurs. By highlighting all cancel 
attempts (successful or not), the All Cancels Report helps firms 
identify patterns, refine strategies to improve cancel efficiency, and 
better manage risk and exposure.
    The Exchange notes the data information contained within the 
proposed All Cancels Report is similar to data fields that are included 
in the existing Missed Cancels Report.\17\
---------------------------------------------------------------------------

    \17\ See e.g. Securities Exchange Act Release No. 102240 
(January 17, 2025), 90 FR 8067 (January 23, 2025) (SR-CboeEDGX-2025-
002) adopting the Missed Cancels Report and Missed Liquidity Report.
---------------------------------------------------------------------------

Implementation
    The Exchange will announce via Exchange Notice the implementation 
date of the proposed rule change. While the Exchange notes that it 
proposes to introduce this report on August 25, 2025, this date may be 
subject to change.
2. Statutory Basis
    The Exchange believes that the proposed All Cancels Report is 
consistent with Section 6(b) of the Act,\18\ in general, and furthers 
the objectives of Section 6(b)(5) of the Act,\19\ 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

[[Page 40676]]

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.\20\ This proposal is in 
keeping with those principles in that it promotes increased 
transparency through the dissemination of the optional All Cancels 
Report to those interested in paying to receive this report.
---------------------------------------------------------------------------

    \18\ 15 U.S.C. 78f.
    \19\ 15 U.S.C. 78f(b)(5).
    \20\ 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 report. The report 
will allow subscribing firms 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 subscribing firm that 
chooses to subscribe to the proposed report. As discussed, the proposed 
report is 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 would be specific to 
the Recipient Firm's messages.
    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.'' \21\
---------------------------------------------------------------------------

    \21\ 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 addition to the Cboe Timestamping Service (i.e., the All 
Cancels Reports) provides investors with a new option for receiving 
market data, which was a primary goal of the market data amendments 
adopted by Regulation NMS.\22\
---------------------------------------------------------------------------

    \22\ See Regulation NMS Adopting Release, supra, at 37503.
---------------------------------------------------------------------------

    The proposed report is designed for subscribing firms that are 
interested in gaining insight into latency in connection with their 
respective cancel messages. 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 report provides greater 
visibility of cancel behavior and messaging activity--particularly for 
analyzing cancel patterns across all market scenarios, including those 
where no trade occurred.
    As mentioned above, the previously adopted Missed Cancels Report 
contains similar trading related data that has been reviewed and 
approved by the Commission.\23\ Specifically, the data points within 
the reports are identical, with the exception that the Missed Cancels 
Report also contains the following data points as these are all only 
applicable when there is a trade record: Execution ID, Trade Condition 
and Aggressor Order Type.
---------------------------------------------------------------------------

    \23\ See supra note 17.
---------------------------------------------------------------------------

    The Exchange proposes to provide the reports on a voluntary basis 
and no firm will be required to subscribe to this proposed report. The 
Exchange notes that there is no rule or regulation that requires the 
Exchange to produce, or that a firm elects to receive, this report. It 
is entirely a business decision of each firm to subscribe to this 
report. The Exchange proposes to offer the report as a convenience to 
firm to provide them with additional information regarding trading 
activity on the Exchange on a delayed basis after the close of regular 
trading hours. A firm that chooses to subscribe to the reports may 
discontinue receiving either report at any time if that firm determines 
that the information contained in the All Cancels Report is no longer 
useful.
    In summary, the proposed report 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 
market participants.

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 All Cancels Report will enhance competition 
by providing a new option for receiving market data to market 
participants. The proposed Report will also further enhance competition 
between exchanges by allowing the Exchange to expand its existing 
product offerings, which may lead other exchanges who currently offer 
similar products to do the same.\24\
---------------------------------------------------------------------------

    \24\ MIAX Emerald offers a Liquidity Taker Event Report, 
analogous to the Exchange's Missed Liquidity Report under its Cboe 
Timestamping Services. See MIAX Emerald Rule 531. 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 (<a href="http://miaxglobal.com">miaxglobal.com</a>). 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 Missed Cancels Report serves a similar purpose as 
the Missed Liquidity Report--providing TPHs additional information 
to better understand the efficacy of their incoming orders and 
cancel messages.

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

[[Page 40677]]

    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 the proposed report, and the 
Exchange is not required to make this report available to investors. 
Rather, the Exchange is voluntarily making these reports available, as 
requested by subscribing firms, and subscribing firms 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

    The Exchange has filed the proposed rule change pursuant to Section 
19(b)(3)(A)(iii) of the Act \25\ and Rule 19b-4(f)(6) thereunder.\26\ 
Because the proposed rule change does not: (i) significantly affect the 
protection of investors or the public interest; (ii) impose any 
significant burden on competition; and (iii) become operative prior to 
30 days from the date on which it was filed, or such shorter time as 
the Commission may designate, if consistent with the protection of 
investors and the public interest, the proposed rule change has become 
effective pursuant to Section 19(b)(3)(A) of the Act \27\ and Rule 19b-
4(f)(6)(iii) thereunder.\28\
---------------------------------------------------------------------------

    \25\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \26\ 17 CFR 240.19b-4(f)(6).
    \27\ 15 U.S.C. 78s(b)(3)(A).
    \28\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change, along 
with a brief description and text of the proposed rule change, at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) \29\ normally 
does not become operative prior to 30 days after the date of the 
filing. However, pursuant to Rule 19b-4(f)(6)(iii),\30\ the Commission 
may designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange has asked 
the Commission to waive the 30-day operative delay so that the Exchange 
may introduce this new report by August 25, 2025. The Exchange states 
that the proposed report does not present any substantive issues not 
already considered by the Commission. The proposed report includes data 
fields that are already included in the previously established Missed 
Cancels Report. For these reasons, and because the proposed rule change 
does not raise any new or novel regulatory issues, the Commission finds 
that waiving the 30-day operative delay is consistent with the 
protection of investors and the public interest. Accordingly, the 
Commission hereby waives the 30-day operative delay and designates the 
proposed rule change as operative upon filing.\31\
---------------------------------------------------------------------------

    \29\ 17 CFR 240.19b-4(f)(6).
    \30\ 17 CFR 240.19b-4(f)(6)(iii).
    \31\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See U.S.C. 78c(f).
---------------------------------------------------------------------------

    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 under 
Section 19(b)(2)(B) \32\ of the Act to determine whether the proposed 
rule change should be approved or disapproved.
---------------------------------------------------------------------------
