Self-Regulatory Organization’s Statement of the Purpose of, and Statutory Basis
for, the Proposed Rule Change
1.

Purpose

The Exchange proposes to amend its Fees Schedule to clarify its fees for Certification
Logical Port fees.3
By way of background, the Exchange offers a variety of logical ports, which provide
users with the ability within the Exchange’s System to accomplish a specific function through a
connection, such as order entry, data receipt or access to information. Specifically, the Exchange
offers Logical Ports,4 Purge Ports5, Multicast PITCH GRP Ports and Multicast PITCH Spin
Server Ports6. For each type of the aforementioned logical ports that is used in the production
environment, the Exchange also offers corresponding ports which provide Members and nonMembers access to the Exchange’s certification environment to test proprietary systems and
applications (i.e., “Certification Logical Ports”). The certification environment facilitates testing
using replicas of the Exchange’s production environment process configurations which provide
for a robust and realistic testing experience. For example, the certification environment allows
unlimited firm-level testing of order types, order entry, order management, order throughput,
acknowledgements, risk settings, mass cancelations, and purge requests. The Exchange
currently provides free of charge one Certification Logical Port per port type offered in the
production environment (i.e., Logical Ports, Purge, Multicast PITCH GRP, and Multicast PITCH
Spin Server Ports) and a monthly fee of $250 per Certification Logical Port for any additional

The Exchange initially filed this proposed rule change on May 31, 2024 for June 3, 2024 effectiveness (SRCboeBYX-2024-018). On June 13, 2024, the Exchange withdrew that filing and submitted this filing.

Logical Ports include FIX and BOE ports (used for order entry), drop logical port (which grants users the
ability to receive and/or send drop copies) and ports that are used for receipt of certain market data feeds.

Purge Ports are dedicated ports that permit a user to simultaneously cancel all or a subset of its orders in
one or more symbols across multiple logical ports by requesting the Exchange to effect such cancellation.

Spin Ports and GRP Ports are used to request and receive a retransmission of data from the Exchange’s
Multicast PITCH data feeds.

Certification Logical Ports.7
The Exchange proposes to make clear in the notes section under the Logical Port Fees
section of the Fees Schedule that the Certification Logical Port fees only apply if the
corresponding logical port type is also in the production environment. For example, if the
Exchange intends to adopt a new port type that has not yet been launched in the live production
environment, any certification port for that port type will be free until such time that the
proposed new port is in the production environment. Once any new logical port type is in the
live production environment, Members and Non-Members will only be entitled to one free
certification logical port for that port type, and any additional certifications ports of that type will
be assessed the regular monthly $250 per port charge.
The Exchange notes that purchasing additional Certification Logical Ports continues to be
voluntary and not required in order to participate in the production environment, including live
production trading on the Exchange. Additionally, Members and non-Members are not required
to purchase any particular production logical port in order to receive a corresponding
Certification Logical Port free of charge.8 Further, the Exchange also notes that other exchanges
similarly assess fees related to their respective testing environments.9
2.

Statutory Basis

The Exchange believes the proposed rule change is consistent with the Securities
Exchange Act of 1934 (the “Act”) and the rules and regulations thereunder applicable to the
Exchange and, in particular, the requirements of section 6(b) of the Act.10 Specifically, the

For example, if a Member maintains 3 FIX Certification Logical Ports, 1 Purge Certification Logical Port,
and 1 set of Multicast PITCH Spin Server Certification Logical Port, the Member will be assessed $500 per
month for Certification Logical Port Fees (i.e., 1 FIX, 1 Purge and 1 set of Multicast PITCH Spin Server
Certification Logical Ports x $0 and 2 FIX Certification Logical Ports x $250).

For example, a Member may obtain a Certification Purge Port free of charge, even if that Member has not
otherwise purchased a Purge Port for the live production environment. Certification Logical Ports are not
automatically enabled, but rather must be proactively requested by Members or Non-Members.

See e.g., Nasdaq Stock Market LLC, Equity 7, Pricing Schedule, Section 130. See also MIAX Options
Exchange Fee Schedule, Section 4, Testing and Certification Fees.

15 U.S.C. 78f(b).

Exchange believes the proposed rule change is consistent with the section 6(b)(5)11 requirements
that the rules of an exchange be designed to prevent fraudulent and manipulative acts and
practices, to promote just and equitable principles of trade, to foster cooperation and
coordination with persons engaged in regulating, clearing, settling, processing information with
respect to, and facilitating transactions in securities, 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. Additionally, the Exchange believes the proposed rule change
is consistent with section 6(b)(4) of the Act,12 which requires that Exchange rules provide for the
equitable allocation of reasonable dues, fees, and other charges among its Members and other
persons using its facilities.
As noted above, the Exchange’s certification environment provides a robust and realistic
testing experience using a replica of the Exchange’s production environment process
configurations. This environment enables market participants to manage risk more effectively
through testing software development changes in certification prior to implementing them in the
live trading environment, thereby reducing the likelihood of a potentially disruptive system
failure in the live trading environment, which has the potential to affect all market participants.
The Exchange believes this is especially true when testing a new port type that has not yet launched
in the production environment. As such, the Exchange believes it’s reasonable to only assess the
Certification Logical Port fee to ports that are also available in the production environment as to not
discourage the testing of new ports ahead of any respective launch date. The Exchange also
believes applying the Certification Logical Port fee is reasonable once such ports are available in the
production environment because while such ports will no longer be completely free, Members and
non-Members will continue to be entitled to receive free of charge one Certification Logical Port for
such port. The Exchange continues to believe one Certification Logical Port per logical port type

will be sufficient for most Members or Non-Members and indeed anticipates that the majority of
users will not purchase additional Certification Logical Ports. For those who wish to obtain
additional Certification Logical Ports based on their respective business needs, such as those
wishing to test across various diverse systems within their own infrastructure, they are able to do so
for a modest fee. Indeed, the decision to purchase additional ports is optional and no market
participant is required or under any regulatory obligation to purchase excess Certification
Logical Ports in order to access the Exchange’s certification environment.13 Further, the
Exchange has observed that market participants that do choose to purchase additional Certification
Logical Ports maintain significantly fewer Certification Logical Ports as compared to the
corresponding logical ports they use in the production in environment.
The Exchange believes the proposal to make clear that the Certification Logical Port fee
applies only to logical ports that are in the production environment is equitable and not unfairly
discriminatory because it applies uniformly to all market participants that choose to obtain
additional Certification Logical Ports and all market participants will have further clarity as to
which certification ports are subject to the current fee. The Exchange also believes the proposed
change is reasonable, equitable and not unfairly discriminatory because it is designed to encourage
market participants to avail themselves of Certification Logical Ports for new port types before
they launch to become acclimated with the new connectivity offering ahead of going live in the
trading environment. The Exchange believes the proposal to add this language to the notes
section in the Fees Schedule also provides clarity in the rules as to when the Certification Logical
Port fee applies and reduces potential confusion.
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

Although many Members and Non-Members use Certification Logical Ports on a daily basis, the Exchange
notes frequency of use of Certification Logical Ports varies by user and depends on their respective
business needs. To the extent a Member or Non-Member purchases additional Certification Logical Ports
and their needs later change, or they determines they no longer wish to maintain excess Certification
Logical Ports, the Member or Non-Member is free to cancel such ports for the following month(s).

intramarket or intermarket competition that is not necessary or appropriate in furtherance of the
purposes of the Act. The Exchange does not believe that the proposed rule change will impose
any burden on intramarket competition because as the proposed change applies uniformly to all
market participants. Additionally, the Exchange does not believe that the proposed fee creates an
undue burden on competition because the Exchange will continue to offer free of charge one
Certification Logical Port per each logical port type once offered in the production environment.
Also as discussed, the purchase of additional ports is optional and based on the business needs of
each market participant. Moreover, such market participants will continue to benefit from access
to the certification environment, which the Exchange believes provides a robust and realistic
testing experience via a replica of the production environment, which may be especially critical
during the time leading up to the launch of a new port type in the production environment.
The Exchange does not believe that the proposed rule changes will impose any burden on
intermarket competition that is not necessary or appropriate in furtherance of the purposes of the
Act. Particularly, the proposed change applies only to the Exchange’s certification environment.
Additionally, the Exchange notes that it operates in a highly competitive market. Members have
numerous alternative venues that they may participate on and direct their order flow, including
15 other equities exchanges, as well as a number of alternative trading systems and other offexchange venues, where competitive products are available for trading. Indeed, participants can
readily choose to send their orders to other exchanges, and, additionally off-exchange venues, if
they deem overall fee levels at those other venues to be more favorable. Moreover, the
Commission has repeatedly expressed its preference for competition over regulatory intervention
in determining prices, products, and services in the securities markets. Specifically, in
Regulation NMS, the Commission highlighted the importance of market forces in determining
prices and SRO revenues and, also, recognized that current regulation of the market system “has
been remarkably successful in promoting market competition in its broader forms that are most

important to investors and listed companies.”14 The fact that this market is competitive has also
long been recognized by the courts. In NetCoalition v. Securities and Exchange Commission, the
D.C. Circuit stated as follows: “[n]o one disputes that competition for order flow is ‘fierce.’ . . .
As the SEC explained, ‘[i]n the U.S. national market system, buyers and sellers of securities, and
the broker-dealers that act as their order-routing agents, have a wide range of choices of where to
route orders for execution’; [and] ‘no exchange can afford to take its market share percentages
for granted’ because ‘no exchange possesses a monopoly, regulatory or otherwise, in the
execution of order flow from broker dealers’. . . .”.15 Accordingly, the Exchange does not
believe its proposed fee change imposes any burden on competition that is not necessary or
appropriate in furtherance of the purposes of the Act.
