## I. Introduction and Procedural History

                    On February 6, 2024, 24X National Exchange LLC (“24X” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) a Form 1 application under the Securities Exchange Act of 1934 (“Exchange Act”) seeking registration as a national securities exchange under section 6 of the Exchange Act.[1]                                          Notice of the application was published for comment in the                     **Federal Register**                     on March 4, 2024.[2]                                          The Commission received five comments on the Notice [3]                                          and a letter responding to the comments from 24X.[4]                                          On May 31, 2024, the Commission instituted proceedings pursuant to section 19(a)(1)(B) of the Exchange Act [5]                                          to determine whether to grant or deny 24X's application for registration as a national securities exchange under section 6 of the Exchange Act (the “OIP”).[6]                                          After issuance of the OIP, the Commission received six comment letters [7]                                          and a letter responding to the comments from 24X.[8]                                          On August 21, 2024, 24X filed an amendment to its Form 1 application (“Amendment No. 1”),[9]                                          which was published for comment in the                     **Federal Register**                     on September 3, 2024.[10]                                          On August 30, 2024, the Commission extended, pursuant to section 19(a)(1)(B) of the Exchange                           ( print page 97093)                        Act,[11]                                          the time period for granting or denying 24X's Form 1 application for an additional 90 days, until November 29, 2024.[12]                                          After issuance of Amendment No. 1, the Commission received three comment letters [13]                                          and a letter responding to the comments from 24X.[14]                                          On October 23, 2024, 24X filed a second amendment to its Form 1 application (“Amendment No. 2”),[15]                                          which was published for comment in the                     **Federal Register**                     on October 30, 2024.[16]                                          After issuance of Amendment No. 2, the Commission received two comment letters [17]                                          and a letter responding to the comments from 24X.[18] 

The Commission has reviewed 24X's Form 1 application, as amended, together with the comment letters received, in order to make a determination whether to grant such registration. For the reasons set forth below and based on the representations set forth in 24X's Form 1 application, as amended, this order grants 24X's Form 1 application, as amended, for registration as a national securities exchange.

## II. Statutory Standards

                    Pursuant to sections 6(b) and 19(a) of the Exchange Act,[19]                                          the Commission shall by order grant an application for registration as a national securities exchange if the Commission finds, among other things, that the proposed exchange is so organized and has the capacity to carry out the purposes of the Exchange Act and can comply, and can enforce compliance by its members and persons associated with its members, with the provisions of the Exchange Act, the rules and regulations thereunder, and the rules of the exchange.[20] 

                    As discussed in greater detail below, the Commission finds that 24X's application, as amended, for registration as a national securities exchange meets the requirements of the Exchange Act and the rules and regulations thereunder. Further, the Commission finds that the proposed rules of 24X are consistent with section 6 of the Exchange Act in that, among other things, they are designed to: (1) assure fair representation of the exchange's members in the selection of its directors and administration of its affairs and provide that, among other things, one or more directors shall be representative of investors and not be associated with the exchange, or with a broker or dealer; [21]                                          (2) prevent fraudulent and manipulative acts and practices, promote just and equitable principles of trade, foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, and remove impediments to and perfect the mechanisms of a free and open market and a national market system; [22]                                          (3) not permit unfair discrimination between customers, issuers, or dealers; [23]                                          and (4) protect investors and the public interest.[24]                                          The Commission also finds that the proposed rules of 24X are consistent with section 11A of the Exchange Act.[25]                                          Finally, the Commission finds that 24X's proposed rules do not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act.[26] 

## III. Discussion

### A. Ownership and Governance of 24X

                    24X is a Delaware limited liability company,[27]                                          which is wholly-owned by its sole member, 24X US Holdings LLC (“24X US”), which also is a Delaware limited liability company.[28]                                          24X US, in turn, is wholly-owned by 24X Bermuda Holdings LLC (“24X Bermuda”), which is a limited liability company formed under the laws of Bermuda.[29]                                          24X US will be managed by, and all decisions regarding 24X US will be made by, 24X Bermuda.[30]                                          Generally, the members of 24X Bermuda include holders of “Preferred Units,” [31]                                          “Common Units” [32]                                          and “Non-Voting Units.” [33]                                          Common Units and Preferred Units except Series Seed-2 Units have general voting power, and are defined as “Voting Units.” [34]                                          Each Voting Unit has one vote.[35] 

#### 1. 24X Board of Directors

                    24X proposed that its business and affairs as a national securities exchange will be managed by a Board [36]                                          comprised of a minimum of seven Directors [37]                                          (“24X Board”).[38]                                          The 24X Board will consist of:                

                    (A) one Director who is the Chief Executive Officer of the Exchange and who shall be deemed to be an Industry Director; [39] 

                    (B) Non-Industry Directors,[40]                                          including at least one (1) Independent Director,[41]                                          the number of which shall equal or exceed the sum of the number of Industry Directors and Member Representative Directors; [42] 
      ( print page 97094)    
                    (C) Member Representative Directors, the number of which must be at least twenty percent of the 24X Board; [43]                                          and                

                    (D) at least one of the Non-Industry Directors shall be representative of issuers and investors and not associated with an Exchange Member, a broker, or a dealer.[44] 

                    The first annual meeting of 24X will be held within 90 days after the Commission grants 24X's exchange registration.[45] 

                    In addition, 24X US will appoint the initial Nominating Committee and Member Nominating Committee, consistent with each committee's compositional requirements, to nominate candidates for election to the 24X Board.[46]                                          The Nominating Committee and Member Nominating Committee, after completion of their respective duties for nominating directors for election to the 24X Board for that year, will recommend candidates to serve on the succeeding year's Nominating Committee or Member Nominating Committee, as applicable.[47]                                          Exchange Members [48]                                          will have rights to nominate and elect additional candidates for the Member Nominating Committee pursuant to a petition process.[49] 

                    The Nominating Committee will nominate candidates for election to the 24X Board.[50]                                          For the Member Representative Director positions, the Member Nominating Committee, composed solely of Member Representative Committee or Panel Members,[51]                                          shall consult with the Nominating Committee and the Chairman of the 24X Board and solicit comments from Exchange Members for the purpose of approving and submitting names of candidates for election to the position of Member Representative Director.[52]                                          If no candidates are nominated pursuant to a petition process, then the initial nominees approved and submitted by the Member Nominating Committee will be nominated as Member Representative Directors by the Nominating Committee.[53]                                          If a petition process produces additional candidates, then the candidates nominated pursuant to the petition process, together with those nominated by the Member Nominating Committee, will be presented to Exchange Members for election to determine the final designees for any open Member Representative Director positions.[54]                                          In the event of a contested election, the candidates who receive the most votes will be selected as the Member Representative Director designees by the Member Nominating Committee.[55] 

                    The 24X governance provisions are consistent with the Exchange Act. In particular, the requirement that the number of Member Representative Directors must be at least 20% of the 24X Board and the means by which they will be chosen by Exchange Members provides for the fair representation of members in the selection of directors and the administration of 24X and therefore are consistent with section 6(b)(3) of the Exchange Act.[56]                                          This requirement helps to ensure that members of an exchange have a voice in an exchange's self-regulatory program, and that an exchange is administered in a way that is equitable to all those who trade on its market or through its facilities.[57] 

                    In addition, the requirements that the number of Non-Industry Directors equal or exceed the sum of the number of Industry Directors and Member Representative Directors, that at least one Non-Industry Director shall also qualify as an Independent Director, and that at least one of the Non-Industry Directors shall be representative of issuers and investors and not associated with an Exchange Member, a broker, or a dealer on the 24X Board satisfy the requirements in section 6(b)(3) of the Exchange Act,[58]                                          which requires in part that one or more directors be representative of issuers and investors and not be associated with a member of the exchange, or with a broker or dealer. The Commission previously has stated that the inclusion of public, non-industry representatives on exchange oversight bodies is an important mechanism to support an exchange's ability to protect the public interest.[59]                                          Further, the presence of public, non-industry representatives can help to ensure that no single group of market participants has the ability to systematically disadvantage other market participants through the exchange governance process. Public directors can provide unbiased perspectives, which may enhance the ability of the 24X Board to address issues in a non-discriminatory fashion and foster the integrity of the Exchange.                

#### 2. Exchange Committees

                    24X has proposed to establish several named committees of the 24X Board, including an Appeals Committee [60]                                          and a Regulatory Oversight Committee,[61]                                          as well as the Nominating Committee and Member Nominating Committee, discussed above.[62]                                          The Appeals                           ( print page 97095)                        Committee will consist of two Independent Directors and one Member Representative Director.[63]                                          Each member of the Regulatory Oversight Committee must be an Independent Director.[64] 

                    The named committees that 24X proposed, which are similar to the named committees maintained by other exchanges,[65]                                          are designed to help enable the Exchange to carry out its responsibilities under the Exchange Act and are consistent with the Exchange Act, including section 6(b)(1), which requires, in part, an exchange to be so organized and have the capacity to carry out the purposes of the Exchange Act.[66] 

                    The Commission received one comment on Exhibit J of 24X's Form 1.[67]                                          Regarding the proposed 24X Board and committees, this commenter stated that filling in the charts set forth in Exhibit J of 24X's Form 1 with “TBD” and “TO BE PROVIDED” “does not provide the Commission with sufficient information with which to assess compliance with the law or Commission Rules.” [68]                                          The commenter further stated that “[t]he Exchange failed to provide the names, classifications, terms, and types of businesses of the persons to fill the required roles. The point of the chart is to have those boxes filled in. They are `to be provided' now—not in the future. What would be the basis for the Commission's approval?” [69]                                          24X stated that it has not commenced operations and that “[o]nce directors and committee members are determined,” 24X will update its Form 1 as required under Rule 6a-2 under the Exchange Act.[70] 

                    Exhibit J requires certain information for officers, governors, members of all standing committees, or persons performing similar functions, who “presently hold or have held their offices or positions during the previous year.” [71]                                          Exhibit J of 24X's Form 1 application indicates that Dmitri Galinov will be the “Industry/Chief Executive Officer” of 24X. Exhibit J also lists Dmitri Galinov as the Head of Equities for 24X, and other officers of 24X including David Sassoon as General Counsel; Jeremy Sanchez as Chief Regulatory Officer; and Jason Woerz as Chief Operating Officer.                

                    24X has not yet commenced operations, and therefore, the nomination and election processes to fill the rest of 24X's Board and committees, as set forth in the 24X LLC Agreement, have not been initiated. Upon approval of 24X's Form 1 application, however, 24X US, as the sole owner of 24X, is required to elect only those persons to the 24X Board and committees that meet the stated compositional requirements set forth in the 24X LLC Agreement, and pursuant to Rule 6a-2 of the Exchange Act, 24X must file an amendment to its Form 1 providing the name, classification, term, and type of business of each person who will be on the 24X Board and 24X committees within 10 days after 24X US elects such persons to the 24X Board, or the Chairman of the 24X Board appoints individuals to the various 24X committees.[72]                                          The information provided by 24X in Exhibit J is consistent with the requirements of the form and the Exchange Act.                

### B. 24X Bermuda and Regulation of the Exchange

                    When 24X commences operations as a national securities exchange, it will have all of the attendant regulatory obligations under the Exchange Act. In particular, 24X will be responsible for the operation and regulation of its trading system and the regulation of its members. Certain provisions in both the 24X and 24X Bermuda governing documents are designed to facilitate the ability of 24X to fulfill its regulatory obligations and to help facilitate Commission oversight of 24X. The discussion below summarizes some of these key provisions.[73] 

#### 1. Ownership Structure; Ownership and Voting Limitations

                    As stated above, 24X will be owned indirectly by 24X Bermuda. The 24X Bermuda LLC Agreement includes restrictions on the ability to own and vote units representing a fractional part of the interest in 24X Bermuda (“Units”).[74]                                          These limitations are designed to prevent any party to the 24X Bermuda LLC Agreement from exercising undue control over the operation of the Exchange and to ensure that the Exchange and the Commission are able to carry out their regulatory obligations under the Exchange Act.[75] 

                    In particular, for so long as 24X Bermuda shall control, directly or indirectly, 24X, no Person,[76]                                          either alone or together with its Related Persons,[77]                                          will be permitted to own,                           ( print page 97096)                        directly or indirectly, of record or beneficially, more than 40% of the then issued and outstanding Units.[78]                                          A more restrictive condition will apply to Exchange Members, who either alone or together with their Related Persons, will be prohibited from owning, directly or indirectly, of record or beneficially, more than 20% of the then issued and outstanding Units.[79]                                          If any party to the 24X Bermuda LLC Agreement purports to transfer [80]                                          any Units in violation of these ownership limits, 24X Bermuda will be required (to the extent funds are legally available) to redeem the Units in excess of the applicable ownership limit.[81] 

                    In addition, no Person, alone or together with its Related Persons, may, directly, indirectly, or pursuant to any voting trust, agreement, plan or other arrangement, vote or cause the voting of Units or give any consent or proxy with respect to Units representing more than 20% of the voting power of the then issued and outstanding Units (“Voting Limitation”).[82]                                          Further, no Person, either alone or together with its Related Persons, under circumstances that would result in the Units that are subject to such agreement, plan, or other arrangement not being voted on any matter or matters or any proxy relating thereto being withheld, where the effect of such agreement, plan, or other arrangement would be to enable any Person, either alone or together with its Related Persons, to vote, possess the right to vote, or cause the voting of Units that would represent more than 20% of such voting power.[83] 

                    The 24X Bermuda Board of Managers will be permitted to waive the 40% ownership limitation and the 20% Voting Limitation pursuant to a resolution duly adopted by the 24X Bermuda Board of Managers if it makes certain determinations.[84]                                          Any such waiver will not be effective unless and until approved by the Commission.[85] 

                    Any Person that proposes to own Units in excess of the 40% ownership limitation, or to vote or grant any proxies or consents with respect to Units constituting more than 20% of the voting power of the then outstanding Units, will be required to deliver written notice to the 24X Bermuda Board of Managers of its intention.[86]                                          The notice must be delivered to the 24X Bermuda Board of Managers not less than 45 days (or any shorter period to which the Board of Managers expressly consents) before the proposed ownership of such Units or the proposed vote.[87] 

                    The 24X Bermuda LLC Agreement also contains provisions that are designed to further safeguard the ownership limitation and Voting Limitation described above or are otherwise related to direct and indirect changes in control. Specifically, any Person that, either alone or together with its Related Persons beneficially owns, directly or indirectly (whether by acquisition or a change in the number of Units outstanding), of record or beneficially 5% or more of the then outstanding Units will be required to notify the 24X Bermuda Board of Managers in writing of such ownership.[88]                                          Thereafter, such persons will be required to update 24X Bermuda of any increase or decrease of 1% or more in their previously reported ownership percentage.[89] 

                    The 24X LLC Agreement does not include change of control provisions that are similar to those in the 24X Bermuda LLC Agreement and the 24X US LLC Agreement because the 24X LLC Agreement instead explicitly identifies its sole owner as 24X US, and in turn the 24X US LLC Agreement explicitly identifies 24X Bermuda as its sole owner.[90]                                          Thus, any changes in the ownership of 24X would require the 24X LLC Agreement to be amended. Any amendment to the 24X LLC Agreement, including to ownership of                           ( print page 97097)                        24X, would constitute a proposed rule change under section 19(b) of the Exchange Act [91]                                          and Rule 19b-4 [92]                                          thereunder that will be required to be filed with, or filed with and approved by, the Commission.[93]                                          Moreover, pursuant to the 24X LLC Agreement, any transfer of limited liability company interests of 24X will be subject to prior approval by the Commission pursuant to the rule filing procedure under section 19 of the Exchange Act.[94] 

                    Although 24X Bermuda is not directly responsible for regulation, its activities with respect to the operation of 24X must be consistent with, and must not interfere with, the self-regulatory obligations of 24X.[95]                                          As described above, the provisions applicable to changes in control of 24X Bermuda (through changes in ownership of Units in 24X Bermuda) as well as the Voting Limitation imposed on owners of 24X Bermuda who also are Exchange Members, are designed to help prevent any owner of 24X Bermuda from exercising undue influence or control, either direct or indirect, over the operation of the Exchange and to help ensure that the Exchange retains a sufficient degree of independence to effectively carry out its regulatory obligations under the Exchange Act.                

                    In addition, these limitations are designed to address the conflicts of interests that might result from a member of a national securities exchange owning interests in the exchange. As the Commission has stated in the past, an exchange member's ownership interest in an entity that controls an exchange could become so large as to cast doubt on whether the exchange may fairly and objectively exercise its self-regulatory responsibilities with respect to such member.[96]                                          An exchange member that is a controlling shareholder of an exchange could seek to exercise that controlling influence by directing the exchange to refrain from, or the exchange may hesitate to, diligently monitor and conduct surveillance of the member's conduct or diligently enforce the exchange's rules and the federal securities laws with respect to conduct by the member that violates such provisions. As such, these requirements are designed to minimize the potential that a person or entity can improperly interfere with or restrict the ability of the Exchange to effectively carry out its regulatory oversight responsibilities under the Exchange Act.                

                    The Commission received one comment addressing the governance structure proposed by 24X.[97]                                          This commenter stated 24X's ownership and voting structure “facially violate Commission Rules and the law.” [98]                                          According to this commenter “[24X] asserts that if the Commission approves its application, it has internal company documents that promise (to itself) that it will come into compliance with the law and Commission Rules within nine months of the approval. It is unclear whether or how this promise for future compliance would be enforceable, much less by whom.” [99] 

                    In response to the commenter's concern about 24X's ownership and voting structure, 24X explained that “although the Exchange Act does not set forth any specific ownership and voting limitations applicable to exchanges, the Commission typically has expected exchanges to include in their governing documents certain limitations on ownership and voting. 24X's application includes each of these typical limitations on ownership and voting.” [100]                                          24X stated that “[t]he only exception to such limitations is a request for a very brief, temporary exemption from certain ownership and voting limitation[s].” [101] 

                    24X's and 24X Bermuda's proposed governance provisions are consistent with the Exchange Act, including section 6(b)(1), which requires, in part, an exchange to be so organized and have the capacity to carry out the purposes of the Exchange Act.[102]                                          In particular, these requirements are designed to minimize the potential that a person could improperly interfere with or restrict the ability of the Commission or 24X to effectively carry out their regulatory oversight responsibilities under the Exchange Act.                

                    24X has proposed ownership and voting limitations in Article 9, Section 9.2 of the 24X Bermuda LLC Agreement that are consistent with the ownership and voting limitations in place across all other national securities exchanges,[103]                                          and thus are designed to enable 24X to meet its obligations under the Exchange Act.                

#### a. Temporary Exemption

                    24X proposes that Dmitri Galinov and his Related Persons [104]                                          have a temporary exemption from the ownership limitation set forth in Section 9.2 of the 24X Bermuda LLC Agreement until nine (9) months after the Commission grants 24X's application for registration as a national securities exchange or until 24X commences operation, if later than nine (9) months.[105]                                          Further, 24X proposes in the 24X Bermuda LLC Agreement that if Dmitri Galinov and his Related Persons do not comply with the ownership limitation in Section 9.2 of the 24X Bermuda LLC Agreement within the applicable time period, then 24X Bermuda shall redeem all of the Units the holding of which by Dmitri Galinov and/or his Related Persons results in a violation of Section 9.2 for a price per Unit, as applicable, equal to the lesser of (a) book value or (b) Fair Market Value of such Units.[106]                                          24X also proposes that Dmitri Galinov and his Related Persons shall have a temporary exemption from the Voting Limitation set forth in Section 9.2 of the 24X Bermuda LLC Agreement until nine (9) months after the Commission grants 24X's application for registration as a national securities exchange or until 24X commences operation, if later than nine (9) months, but only with respect to any vote regarding any merger, consolidation or dissolution of the 24X Bermuda or any sale of all or substantially all of the assets of the 24X Bermuda.[107] 

                    Exhibit K of 24X's Form 1 application provides that “Dmitri Galinov owns 7,000,000 Common Units and 179,215 Seed-3 Preferred Units, for a total of 7,179,215 Units for all classes outstanding,” [108]                                          and that “Dmitri Galinov is a Related Person of KNG CAPITAL LLC, Tanya Nazarov-Kenneally, and Vladimir Nazarov. KNG CAPITAL LLC owns 320,616 Seed-1 Preferred Units, which represents 1.85% of all classes of outstanding Units.                           ( print page 97098)                        Tanya Nazarov-Kenneally owns 1794 Seed-3 Preferred Units, which represents 0.01% of all classes of outstanding Units. Vladimir Nazarov owns 7176 Seed-3 Preferred Units, which represents 0.04% of all classes of outstanding Units.” [109]                                          Accordingly, Exhibit K states that “on an aggregate basis, Dmitri Galinov, together with his Related Persons, owns 43.29% of the Units of all classes of outstanding Units.” [110] 

                    In a letter, 24X stated that the temporary exemption would provide it with a brief period to bring its ownership and voting structure in line with the ownership and voting restrictions upon SEC approval.[111]                                          24X also stated that the Commission had granted “prior exchange applications with such limited exceptions to the ownership and voting restrictions.” [112] 

                    The Commission finds that the limited temporary exemption in Article 9, Section 9.2(g) of the 24X Bermuda LLC Agreement from the ownership limitation and Voting Limitation set forth in Article 9, Section 9.2 of the 24X Bermuda LLC Agreement for Dmitri Galinov and his Related Persons is consistent with the Exchange Act. As discussed above, the ownership limitation and Voting limitation are designed to prevent any party from exercising undue control over the operation of the 24X and ensure that 24X is able to carry out its regulatory obligations under the Exchange Act. The exemption is designed to prevent Dmitri Galinov and his Related Persons from exercising undue control over 24X and minimize the possibility that 24X's ability to carry out its self-regulatory responsibilities under the Exchange Act could be impaired. Specifically, the exemption is for a defined period of time that is based on 24X's approval as a national securities exchange or commencement of its exchange operations. Thus, the exemption is designed to ensure that once 24X is a self-regulatory organization (“SRO”), the exemption will terminate within a specified period of time. In addition, the exemption from the Voting Limitation applies only with respect to the limited situations involving any merger, consolidation or dissolution of the 24X Bermuda or any sale of all or substantially all of the assets of the 24X Bermuda that will not permit undue control over 24X or impair the regulatory responsibilities of 24X. The temporary exemption is designed to afford Dmitri Galinov and his Related Persons the ability to protect the investment they have already made in the establishment of 24X that is over the current ownership limitation, represented by 24X to be 3.29% of the Units of all outstanding Units.[113] 

                    As part of its Form 1 application, 24X also has included in the 24X Bermuda LLC Agreement a representation that 24X Bermuda will redeem all of the Units the holding of which by Dmitri Galinov and/or his Related Persons results in a violation of the applicable 40% ownership limitation for a price per Unit, as applicable, equal to the lesser of (a) book value or (b) Fair Market Value of such Units. The 24X Bermuda LLC Agreement further provides that such redemption shall occur nine (9) months after the date of approval by the Commission of 24X's Form 1 application or until commencement of the operation of 24X, if later than nine (9) months. Thus, in response to the commenter, 24X has established a mechanism to ensure compliance with the ownership limitation and Voting Limitation set forth in the 24X Bermuda LLC Agreement upon expiration of the stated time period. 24X Bermuda's Managers and officers must comply with the federal securities laws and the rules and regulations promulgated thereunder and are deemed to agree to cooperate with the Commission and 24X in respect of the Commission's oversight responsibilities regarding 24X and the self-regulatory functions and responsibilities of 24X.[114]                                          Therefore, should there be a need to pursue enforcement of the redemption requirement required of 24X Bermuda, 24X Bermuda's Managers and officers must comply with the obligation and must cooperate with those efforts by the Commission and 24X to ensure that such redemption occurs. Finally, should 24X Bermuda not redeem the Units owned by Dmitri Galinov and his Related Persons within the specified time period, the Commission may take action against 24X under section 19(h) of the Exchange Act.[115] 

#### 2. Regulatory Independence and Oversight

                    Although 24X Bermuda will not itself carry out regulatory functions, its activities with respect to the operation of 24X must be consistent with, and must not interfere with, 24X's self-regulatory obligations. In this regard, 24X and 24X Bermuda propose to adopt certain provisions in their respective governing documents that are designed to help maintain the independence of the regulatory functions of 24X. These proposed provisions are substantially similar to those included in the governing documents of other exchanges that recently have been granted registration.[116]                                          Specifically:                
    - the managers, officers, employees, and agents of 24X Bermuda must give due regard to the preservation of the independence of the self-regulatory function of 24X and to its obligations to investors and the general public and must not take actions which would interfere with the effectuation of decisions by the Exchange Board relating to its regulatory functions (including disciplinary matters) or which would interfere with 24X's ability to carry out its responsibilities under the Exchange Act. [117]  
      ( print page 97099)        - 24X Bermuda must comply with the federal securities laws and the rules and regulations promulgated thereunder, and must cooperate with the Commission, 24X, Financial Industry Regulatory Authority, Inc. (“FINRA”), and any other SRO of which any routing broker for 24X is a member, pursuant to and to the extent of their respective regulatory authority. [118]                                           In addition, 24X Bermuda's managers, officers, employees, and agents must comply with the federal securities laws and the rules and regulations promulgated thereunder and are deemed to agree to cooperate with: (1) the Commission and 24X in respect of the Commission's oversight responsibilities regarding 24X and the self-regulatory functions and responsibilities of 24X; and (2) FINRA, any other SROs of which any routing broker of 24X is a member, and any routing broker of 24X in respect of FINRA's and any such other SRO's oversight responsibilities regarding any routing broker of 24X, as applicable. [119]                                           24X Bermuda shall take reasonable steps necessary to cause its managers, officers, employees and agents to so cooperate. [120]  
    - 24X Bermuda, and its managers, officers, employees, and agents must submit to the jurisdiction of the U.S. federal courts, the Commission, and 24X, for purposes of any suit, action or proceeding pursuant to the U.S. federal securities laws, and the rules and regulations thereunder, arising out of, or relating to, 24X activities. [121]  
    - All books and records of 24X reflecting confidential information pertaining to the self-regulatory function of 24X (including but not limited to disciplinary matters, trading data, trading practices, and audit information) must be retained in confidence by 24X and its personnel, including its Directors, officers, employees, and agents, and will not be used by 24X for any non-regulatory purposes and shall not be made available to any person (including, without limitation, any Exchange Member) other than personnel of the SEC, and those personnel of 24X, members of Committees, members of the 24X Board, hearing officers and other agents of 24X to the extent necessary or appropriate to properly discharge the self-regulatory responsibilities of 24X. [122]                                           Similar provisions apply to 24X Bermuda and its personnel, managers, officers, employees, and agents. [123]  
    - The books and records of 24X and 24X Bermuda must be maintained in the United States  [124]                                           and, to the extent they are related to the operation or administration of 24X, 24X Bermuda's books and records will be subject at all times to inspection and copying by the Commission and 24X. [125]  
    - Furthermore, to the extent 24X Bermuda's corporate, financial and similar records, reports and documents, including all financial statements, books and records and minutes of proceedings, are related to the activities of 24X, such corporate, financial and similar records, reports and documents, including all financial statements, books and records and minutes of proceedings, as well as premises, managers, officers, employees and agents of 24X Bermuda shall be deemed to be the corporate, financial and similar records, reports and documents, including all financial statements, books and records and minutes of proceedings, as well as premises, managers, officers, employees or agents, as applicable, of 24X for the purposes of, and subject to oversight pursuant to, the Exchange Act. [126]  
    - 24X Bermuda will take reasonable steps necessary to cause its manager, officers, employees, and agents, prior to accepting a position as a manager, officer, employee or agent (as applicable) with 24X Bermuda to consent in writing to the applicability of provisions regarding non-interference, confidentiality, books and records, compliance and cooperation, jurisdiction, and regulatory obligations, with respect to their activities related to 24X. [127]  
    - The 24X Bermuda LLC Agreement requires that, so long as 24X Bermuda controls 24X, any changes to that document must be submitted to the Exchange Board for approval, and, if such change is required to be filed with the Commission pursuant to section 19(b) of the Exchange Act and the rules and regulations thereunder, such change shall not be effective until filed with and effective by operation of law, or filed with, and approved by, the Commission. [128]  

                    The provisions discussed in this section, which are designed to help ensure the independence of 24X's regulatory function and facilitate the ability of 24X to carry out its regulatory responsibilities under, and operate in a manner consistent with, the Exchange Act, are appropriate and consistent with the requirements of the Exchange Act, particularly with Section 6(b)(1), which requires, in part, an exchange to be so organized and have the capacity to carry out the purposes of the Exchange Act.[129] 

                    Further, section 19(h)(1) of the Exchange Act [130]                                          provides the Commission with the authority “to suspend for a period not exceeding twelve months or revoke the registration of [an SRO], or to censure or impose limitations upon the activities, functions, and operations of [an SRO], if [the Commission] finds, on the record after notice and opportunity for hearing, that [the SRO] has violated or is unable to comply with any provision of the Exchange Act, the rules or regulations thereunder, or its own rules or without reasonable justification or excuse has failed to enforce compliance . . . ” with any such provision by its members (including associated persons thereof). If the Commission were to find, or become aware of, through staff review and inspection or otherwise, facts indicating any violations of the Exchange Act, including without limitation sections 6(b)(1) and 19(g)(1),[131]                                          these matters could provide the basis for a disciplinary proceeding under section 19(h)(1) of the Exchange Act.[132] 

                    Even in the absence of the governance provisions described above, under section 20(a) of the Exchange Act,[133]                                          any person with a controlling interest in 24X would be jointly and severally                           ( print page 97100)                        liable with and to the same extent that 24X is liable under any provision of the Exchange Act, unless the controlling person acted in good faith and did not directly or indirectly induce the act or acts constituting the violation or cause of action. In addition, section 20(e) of the Exchange Act [134]                                          creates aiding and abetting liability for any person who knowingly provides substantial assistance to another person in violation of any provision of the Exchange Act or rule thereunder. Further, section 21C of the Exchange Act [135]                                          authorizes the Commission to enter a cease-and-desist order against any person who has been “a cause of” a violation of any provision of the Exchange Act through an act or omission that the person knew or should have known would contribute to the violation. These provisions are applicable to 24X Bermuda.                

#### 3. Regulatory Oversight Committee

                    The regulatory operations of 24X will be monitored by the Regulatory Oversight Committee of the Exchange Board. As mentioned above, the Regulatory Oversight Committee will consist only of Independent Directors.[136]                                          The Regulatory Oversight Committee will be responsible for overseeing the adequacy and effectiveness of 24X's regulatory and SRO responsibilities, assessing 24X's regulatory performance, and assisting the 24X Board (and committees of the 24X Board) in reviewing 24X's regulatory plan and the overall effectiveness of 24X's regulatory functions.[137] 

                    Further, the Chief Regulatory Officer (“CRO”) of 24X will have general supervision over 24X's regulatory operations, including responsibility for overseeing 24X's surveillance, examination, and enforcement functions and for administering any regulatory services agreements with another SRO to which 24X is a party.[138]                                          The Regulatory Oversight Committee, in consultation with the Chief Executive Officer of 24X, will be responsible for establishing the goals, assessing the performance, and fixing the compensation of the CRO and for recommending personnel actions involving the CRO and senior regulatory personnel.[139] 

###                     C.                     *Regulatory Funding and Services*

                    As a prerequisite for the Commission's granting of an exchange's application for registration, an exchange must be organized and have the capacity to carry out the purposes of the Exchange Act.[140]                                          Specifically, an exchange must be able to enforce compliance by its members, and persons associated with its members, with the federal securities laws and rules thereunder and the rules of the exchange.[141]                                          The discussion below summarizes how 24X proposes to conduct and structure its regulatory operations.                

#### 1. Regulatory Funding

                    To help ensure that 24X has and will continue to have adequate funding to be able to meet its responsibilities under the Exchange Act, 24X stated that, if the Commission approves 24X's application for registration as a national securities exchange, 24X Bermuda, through 24X US, will allocate sufficient assets to 24X to enable the Exchange's operation.[142]                                          Specifically, 24X stated that 24X Bermuda shall make prior to the launch of the Exchange a cash contribution of $5 million (in addition to any previously provided in-kind contributions, such as legal, regulatory, and infrastructure-related services) to 24X US. In turn, 24X US will make a corresponding cash contribution of $5 million (in addition to any previously provided in-kind contributions, such as legal, regulatory, and infrastructure-related services) to the Exchange. The Exchange represented that such cash and in-kind contributions will be adequate to operate the Exchange, including the regulation of the Exchange.[143] 

                    24X also represented that there will be a written agreement among 24X Bermuda, 24X US and 24X that requires 24X Bermuda and 24X US to provide adequate funding for the Exchange's operations, including the regulation of the Exchange.[144]                                          Further, 24X stated that the agreement will provide that 24X will receive all fees, including regulatory fees and trading fees payable by the Exchange's members as well as any funds received from any market data fees and tape revenue. In addition, the agreement will provide that 24X Bermuda and 24X US will reimburse 24X for its costs and expenses to the extent that 24X's assets are insufficient to meet its costs and expenses.                

                    Further, the 24X LLC Agreement requires that any Regulatory Funds received by 24X shall not be used for non-regulatory purposes or distributed, advanced or allocated to any Company Member,[145]                                          but rather, shall be applied to fund regulatory operations of the 24X (including surveillance and enforcement activities), or, as the case may be, shall be used to pay restitution and disgorgement of funds intended for customers.[146]                                          Excess non-regulatory funds, as solely determined by the 24X, will be remitted to 24X US in accordance with the 24X LLC Agreement.[147] 

                    One commenter stated that 24X did not provide audited financial statements.[148]                                          24X stated that it believed that it complied with the requirements of Exhibit I regarding financial statements because while 24X has been formed it has not commenced operations and does not have audited financial statements for any fiscal year.[149]                                          24X also stated that the approach it has taken with regard to Exhibit I is consistent with prior exchange applications that have been approved by the SEC based on the same provided information.[150] 

                    The 24X Form 1 provides the Commission with information necessary to make a finding that 24X will operate consistent with its obligations under the Exchange Act.[151]                                          24X has filed financial information about how it intends to fund its operations and has filed financial information in Exhibit D about its owners, 24X Bermuda and 24X US.                           ( print page 97101)                        Exhibit I of Form 1 requires that the applicant submit “[f]or the latest fiscal year of the applicant, audited financial statements which are prepared in accordance with, or in the case of a foreign applicant, reconciled with, United States generally accepted accounting principles, and are covered by a report prepared by an independent public accountant.” [152]                                          24X has not provided audited financial statements nor the report prepared by an independent public accountant because, as it stated in the Form 1, the “Exchange has been formed but has not commenced operations and does not yet have audited financial statements for any fiscal year.” [153]                                          As stated in the instructions for Form 1, “Form 1 is designed to enable the Commission to determine whether an exchange applying for registration is in compliance with the provisions of sections 6 [154]                                          and 19 [155]                                          of the Exchange Act.” [156]                                          In this case, the applicant exchange has no past operations or activity. Moreover, the Commission has approved prior Form 1 applications with similar circumstances.[157]                                          In addition, pursuant to Rule 6a-2(b)(1) of the Exchange Act,[158]                                          as a registered national securities exchange, 24X must file an amendment to its Form 1 application. Exhibits D and I must be filed on or before June 30 of each year and include audited financial information as of the end of the latest fiscal year of the Exchange; thus, the Commission and the public will be informed of 24X's financial activity going forward.[159] 

#### 2. Regulatory Contract With FINRA

                    Although 24X will be an SRO with all of the attendant regulatory obligations under the Exchange Act, it has represented to the Commission that it intends to enter into a regulatory services agreement (“RSA”) with FINRA, under which FINRA as a regulatory services provider will perform certain regulatory functions on 24X's behalf.[160]                                          Specifically, 24X expects that such services will include the performance of investigation, disciplinary, and hearing services.[161]                                          Notwithstanding the RSA, 24X will retain legal responsibility for the regulation of its members and its market and the performance of FINRA as its regulatory services provider. Because 24X anticipates entering into an RSA with FINRA, it has not made provisions to fulfill the regulatory services that will be undertaken by FINRA. Accordingly, the Commission is conditioning the operation of 24X on a final RSA that specifies the services that will be provided to 24X.                

                    It is consistent with the Exchange Act for 24X to contract with FINRA to perform certain examination, enforcement, and disciplinary functions.[162]                                          These functions are fundamental elements of a regulatory program and constitute core self-regulatory functions. FINRA has the expertise and experience to perform these functions for 24X.[163]                                          However, 24X, unless relieved by the Commission of its responsibility, bears the self-regulatory responsibilities and primary liability for self-regulatory failures, not the SRO retained to perform regulatory functions on 24X's behalf.[164]                                          In performing these regulatory functions, however, FINRA may nonetheless bear liability for causing or aiding and abetting the failure of 24X to perform its regulatory functions.[165]                                          Accordingly, although FINRA will not act on its own behalf under its SRO responsibilities in carrying out these regulatory services for 24X, FINRA may have secondary liability if, for example, the Commission finds that the contracted functions are being performed so inadequately as to cause a violation of the federal securities laws or rules thereunder by 24X.[166] 

#### 3. Rule 17d-2 Agreements

                    Section 19(g)(1) of the Exchange Act,[167]                                          among other things, requires every SRO registered as either a national securities exchange or national securities association to comply with the Exchange Act, the rules and regulations thereunder, and the SRO's own rules, and, absent reasonable justification or excuse, enforce compliance by its members and persons associated with its members.[168]                                          Rule 17d-2 of the Exchange Act permits SROs to propose joint plans to allocate regulatory responsibilities amongst themselves for their common rules with respect to their common members.[169]                                          These agreements, which must be filed with and declared effective by the Commission, generally cover areas where each SRO's rules substantively overlap, including such regulatory functions as personnel registration and sales practices. For example, the Commission declared effective a plan to allocate regulatory responsibilities between FINRA and LTSE pursuant to which FINRA assumes examination and enforcement responsibility for broker-dealers that are members of both FINRA and LTSE with respect to the rules of LTSE that are substantially similar to the applicable rules of FINRA, as well as certain specified provisions of the federal securities laws.[170] 
      ( print page 97102)    
                    A Rule 17d-2 plan that is declared effective by the Commission relieves the specified SRO of those regulatory responsibilities allocated by the plan to another SRO.[171]                                          24X has represented to the Commission that it will join all applicable plans, including Rule 17d-2 plans for the allocation of regulatory responsibilities.[172]                                          Similar to other exchanges, the Commission understands from 24X that it will enter into a bilateral Rule 17d-2 agreement covering common members of 24X and FINRA. This agreement will allocate to FINRA regulatory responsibility, with respect to common members, for specified regulatory and enforcement matters arising out of specified common rules and specified provisions of the Exchange Act and the rules and regulations thereunder. In addition, the Commission is conditioning operation of 24X as an exchange on 24X first joining the applicable multilateral Rule 17d-2 plans, including the multi-party Rule 17d-2 plan for the allocation of regulatory responsibilities with respect to certain Regulation NMS and Consolidated Audit Trail Rules and the multi-party Rule 17d-2 plan for the surveillance, investigation, and enforcement of common insider trading rules.[173] 

                    Because 24X anticipates entering into these Rule 17d-2 agreements, it has not made provision to fulfill the regulatory obligations that will be undertaken by FINRA and other SROs under these agreements with respect to common members.[174]                                          Accordingly, the Commission is conditioning the operation of 24X on approval by the Commission of a Rule 17d-2 agreement that allocates the above specified matters to FINRA, and the approval of an amendment to the existing multi-party Rule 17d-2 plans specified above to add 24X as a party.                

### D. 24X Trading System

####                     1. Overview of Trading System [175] 

                    24X proposes to operate a fully automated electronic trading platform [176]                                          for the trading of listed NMS stocks [177]                                          pursuant to unlisted trading privileges (“UTP”) [178]                                          23 hours per day,[179]                                          five (5) days per week, subject to certain trading pauses, as provided in the 24X rules.[180]                                          Similar to other U.S. national securities exchanges, 24X will operate three different trading sessions that span from 4 a.m. to 7 p.m. on each U.S. Business Day: [181]                                          (1) a “Core Market Session” between 9:30 a.m. and 4 p.m.,[182]                                          (2) a “Pre-Market Session” between 4 a.m. and 9:30 a.m.,[183]                                          and (3) a “Post-Market Session” between 4 p.m. and 7 p.m.[184]                                          24X also will operate a fourth trading session, the 24X Market Session,[185]                                          which, as discussed in greater detail below,[186]                                          will operate between 8 p.m. and 4 a.m. Sunday, Monday, Tuesday, Wednesday, and Thursday nights that precede a U.S. Business Day.[187] 

                    24X will not maintain a physical trading floor.[188]                                          One commenter stated that the Form 1 was unclear about 24X's physical locations.[189]                                          24X responded that it “clearly” provided information on the Form 1 execution page as well as Exhibit E.[190]                                          Specifically, 24X stated that its primary address is in Connecticut and that the Exchange will operate out of a third-party data center in New Jersey, with a secondary site located in Illinois.[191]                                          Further, 24X stated that 24X personnel will operate out of its New York office as well as its Connecticut office.[192] 

                    The Form 1 and exhibits provide information about the location of 24X Systems and personnel. The Form 1 Execution Page states that 24X's primary address is in Stamford, Connecticut. Exhibit E states that 24X will operate out of data centers in New Jersey and Illinois and that its personnel will operate out of offices in Connecticut and New York. Exhibit E-1 states that 24X's trading platform will be located in the Equinix data center in New Jersey (NY4) and that its secondary back-up data center will be located in Chicago, Illinois (CH4).[193]                                          24X has provided information about the location of its platform and its personnel.                

                    Only broker-dealer members of 24X and entities that enter into market access arrangements with members (collectively “Users” [194]                                         ) will have access to the 24X System,[195]                                          and only Authorized Traders [196]                                          may obtain access to the 24X System on behalf of Users.[197]                                          Liquidity will be derived from quotes and orders to buy and sell                           ( print page 97103)                        submitted to 24X electronically by Exchange Members.[198]                                          24X proposes to operate a fully automated electronic limit order book with a continuous matching function [199]                                          and orders resting on the book would be ranked and executed in price/time priority.[200] 

                    24X proposes certain rules to govern trading during Exchange Trading Hours other than the 24X Market Session,[201]                                          while other rules and requirements would apply exclusively to trading during the 24X Market Session.[202]                                          For example, 24X proposes to accept Market Orders,[203]                                          Limit Orders [204]                                          and Pegged Orders [205]                                          with various modifiers and time-in-force instructions, although subject to certain limitations [206]                                          during various trading sessions.[207]                                          Specifically, Market Orders would be accepted only during the Core Market Session; Pegged Orders would be accepted only during the Pre-Market Session, the Core Market Session, and the Post-Market Session; and Limit Orders would be accepted during all sessions.[208]                                          Further, pursuant to 24X Rule 11.16, Market Orders and Pegged Orders are not eligible for execution during the 24X Market Session. Orders may be submitted in round lots, odd lots, or mixed lots.[209]                                          24X will permit orders to be entered, canceled, modified, executed on or routed away from 24X during the Pre-Market Session, the Core Market Session, and the Post-Market Session.[210]                                          24X would also permit orders to be entered, canceled, modified or executed on the Exchange during the 24X Market Session.[211] 

                    With respect to the price of executions that would occur on the Exchange,[212]                                          the 24X rules are designed to comply with short sale price test restriction under Rule 201 of Regulation SHO,[213]                                          the order protection requirements of Rule 611 of Regulation NMS,[214]                                          and the National Market System Plan to Address Extraordinary Market Volatility pursuant to Rule 608 of Regulation NMS (“LULD Plan”).[215]                                          24X will permit the use of self-trade protection (“STP”) modifiers to prevent an incoming order from executing against a resting order originating from the same market participant.[216] 

                    In addition, 24X will permit firms to register as Market Makers with affirmative and negative market making obligations.[217]                                          In particular, Market Makers will be required to maintain continuous two-sided quotes of at least 100 shares only during Regular Trading Hours.[218]                                          While Market Makers would have no such obligations during the Pre-Market, Post-Market or 24X Market Sessions, 24X's proposed rules relating to Market Makers are similar to the rules of other national securities exchanges, which do not extend Market Maker obligations to extended hours trading sessions.[219] 

                    In its Form 1, 24X stated that it will join and participate in any applicable national market system plan that other national securities exchanges and/or market centers have joined, including, for example, the three Equity Data Plans [220]                                          that currently govern the collection, consolidation, processing, and dissemination of core data.[221]                                          24X further states that it would “likewise join all other applicable Plans as deemed necessary and in the interest of its Users.” [222] 

                    One commenter stated that the Exchange proposal was “somewhat vague” with regard to transaction fees and that 24X “should give a range of where fees will land compared to other exchanges.” [223]                                          24X responded that its approach to fees is “typical for exchange applications” and that Exhibit E states that it “intends to establish a Fee Schedule setting forth all applicable transaction and other fees . . . close to launch of the Exchange” so that the fees reflect the “competitive landscape at that time.” [224] 

                    Form 1 requires an applicant to provide a description of proposed fees.[225]                                          In its Exhibit E, 24X described its proposed fees, including transaction fees, membership fees, regulatory charges, permit application fees, market                           ( print page 97104)                        data fees, co-location fees, connectivity fees, and bandwidth fees.[226]                                          Further, 24X Rule 15.1, which establishes the Exchange's authority to impose fees, dues, assessments and other charges that 24X may prescribe, lists the following fees that 24X will impose: “membership dues, transaction fees, communication and technology fees, regulatory charges, listing fees, and other fees and charges as the Exchange may determine.” [227]                                          24X also stated that it intends to establish a fee schedule that sets forth all fees, and that the actual fee amounts and types will be determined at a time closer to launch.[228] 

                    24X's Form 1 satisfies the requirements of the Form 1 as it describes the fees that 24X may prescribe. However, any fees, dues or other charges that 24X intends to assess must be filed as a proposed rule change pursuant to section 19(b) of the Exchange Act [229]                                          and Rule 19b-4 thereunder.[230]                                          Exchange fees are subject to the requirements of the Exchange Act, including sections 6(b)(4) and 6(b)(5).[231] 

#### 2. 24X Market Session

                    As discussed above, 24X will operate the 24X Market Session, a fourth trading session that will extend the hours of exchange trading for NMS stocks beyond the existing extended hours sessions.[232]                                          In Amendment No. 2, 24X modified its original proposal for the 24X Market Session to include overnight trading only on certain nights of the week—Sunday through Thursday—that precede a U.S. Business Day.[233]                                          As discussed above,[234]                                          while several exchanges offer a pre-market trading session that may start as early as 4 a.m. on each U.S. Business Day, and most exchanges offer a post-close trading session that ends at 8 p.m. on each U.S. Business Day, 24X's model, as amended, will expand exchange trading hours such that trading on 24X will be conducted on a largely continuous basis during the week subject to a daily one hour trading pause.[235]                                          24X will operate the 24X Market Session, as amended, in a manner that is consistent with current extended hours sessions.[236]                                          Further, as discussed below, 24X will require that 24X Members make disclosures to their customers concerning risks associated with trading during Extended Hours Trading, and has included tailored disclosures that 24X Members must provide to their customers to reflect the potential risks associated with the 24X Market Session, as amended.[237] 

                    The Commission received several comment letters about the proposed operation of the 24X Market Session, which, as initially proposed, would have operated 8 p.m. until 4 a.m. during every U.S. Business Day as well as most of the day on weekends and holidays, subject to proposed trading pauses. Some commenters supported the originally proposed expansion of trading hours.[238]                                          For instance, two commenters stated that the originally proposed 24X Market Session would bring the “current practice of trading 24/7 onto a lit exchange” [239]                                          and that the market should be left to decide whether this is a valuable endeavor.[240]                                          One commenter stated that 24-hour trading already occurs and that “it is better that it be on a national securities exchange with higher regulatory protections afforded by an exchange.” [241] 

                    One commenter stated that its recent research “implies that 23/7 trading will likely improve the market's allocative efficiency relative to the traditional 6.5/5 trading schedule.” [242]                                          This commenter stated that their research studied welfare, measured by the allocative efficiency of the market, in equilibria of two market designs: one with a daily closure, and another in which closure is eliminated. According to the commenter, the research showed that “as long as there is a closure for some time, most of the benefits of a market closure are accrued.” [243]                                          Thus, the commenter stated that it is likely that 24X's proposed 23/7 exchange will maintain the welfare benefits of a market closure, reduce the costs of a prolonged closure, and enhance allocative efficiency.[244] 

                    Several commenters raised concerns about the original proposed expansion of trading hours. For instance, two commenters stated that the proposal would harm retail investors due to low volumes and wide spreads during the extended trading hours and a lack of liquidity would result in a wealth transfer from investors to professionals.[245]                                          Another commenter stated that although 24X suggests that retail investors would welcome 24-hour exchange trading, the demand for investors for overnight and weekend trading seems speculative because no information has been provided about the number of such investors or the relevance of the potential benefit.[246]                                          Another commenter stated that investor demand should be considered to assess whether the expansion of trading hours would justify the market-wide costs.[247] 

                    One commenter suggested a “cautious approach to expanding hours” because its research indicated “negative consequences for retail investment.” [248]                                          Another commenter, however, stated that the research cited did not examine overnight trading or expansion of trading hours but instead examined time zone differences.[249]                                          This commenter stated 24-hour trading “is already here on automated trading systems, so rejecting the 24X application would not restrict retail access to overnight trading at all.” [250] 

                    With respect to the commenter's concern about retail investor participation in the 24X Market Session,[251]                                          24X stated that, as discussed below, the Commission has historically allowed retail participation in expanded trading hours with appropriate disclosures.[252]                                          In Amendment No. 1, 24X amended its 24X Rule 3.21 to                           ( print page 97105)                        provide additional disclosures designed to address the potential risks of the 24X Market Session.[253]                                          24X stated, in response to commenters questioning whether additional trading hours would benefit investors, that “there is substantial interest in expanded trading hours” and that the markets should be able to determine whether the 24X proposal will be successful.[254]                                          24X also stated that its amended rules for the 24X Market Session are a more incremental approach that will address the cost concerns raised by some commenters because it eliminates the potential costs related to weekend and holiday trading.[255]                                          24X further stated that it did not believe that “costs related to innovation should be the basis for the Commission to determine that an exchange application does not comply with the Exchange Act.” [256]                                          24X also stated that the markets will determine whether “its innovative proposal” is successful.[257] 

                    As discussed further below, the Commission finds that the 24X rules for the 24X Market Session, as amended, are consistent with the Exchange Act. Specifically, the 24X Market Session rules are modeled on the rules of national securities exchanges that currently operate trading sessions during extended hours and are designed to address the potential differences in trading compared to Regular Trading Hours.[258]                                          For example, during the 24X Market Session, the only order type that may be submitted is a Limit Order, which requires market participants to set the prices at which they are willing to trade. Accepting only Limit Orders during extended hours sessions can help to address the potential risks that there may be wider spreads,[259]                                          or that prices may be affected by new announcements made by issuers.[260]                                          Other exchanges allow the submission of only limit orders during extended hours sessions.[261] 

                    In addition, 24X Members are required to provide disclosures to customers that will provide information about potential risks of trading in extended hours, including the 24X Market Session. These disclosures are consistent with the rules of other SROs, which require customers to be provided with disclosures regarding the potential risks of extended hours trading.[262]                                          While two commenters stated that investors would be harmed by low liquidity, low volumes and wider spreads, these potential risks are included in the disclosures that must be provided to customers by 24X Members.[263]                                          Investors are provided information about these potential risks and are able to decide whether to participate in extended hours sessions, including the 24X Market Session.                

                    Further, the 24X Market Session will overlap with the extended hours trading that currently occurs in the over-the-counter (“OTC”) market.[264]                                          Accordingly, while the 24X Market Session represents a new trading session for exchange trading, market participants, including retail investors, are already able to trade during the times covered by the 24X Market Session. While commenters stated that investor demand should be considered to assess whether the expansion of trading hours would justify market-wide costs, the Commission is required to consider a Form 1 application for consistency with statutory standards.[265]                                          For the reasons discussed herein, the Commission has determined that the 24X Form 1 is consistent with the Exchange Act and the rules thereunder.                

                    Finally, pursuant to this Form 1, as amended, 24X will not commence operation of the 24X Market Session prior to filing a proposed rule change. Specifically, 24X Rule 1.5(c) requires 24X, prior to commencing operations during the 24X Market Session, to file a proposed rule change, pursuant to section 19(b) of the Exchange Act and the rules thereunder, to amend its rules confirming that 24X is able to comply with its obligations under the Exchange Act during the 24X Market Session and that the Equity Data Plans are prepared to collect, consolidate, process and disseminate quotation and transaction information at all times during the 24X Market Session (“24X Market Session Proposed Rule Change”). As discussed below, the 24X Market Session Proposed Rule Change must be filed with the Commission and approved, or otherwise become effective pursuant to Exchange Act section 19(b), before 24X can provide trading during the 24X Market Session.[266]                                          In the 24X Market Session Proposed Rule Change, 24X must confirm that it is able to comply with its obligations under the Exchange Act during the 24X Market Session and that the Equity Data Plans are prepared to collect, consolidate, process and disseminate quotation and transaction information at all times during the 24X Market Session that is equivalent to the mechanism established for Exchange Trading Hours other than the 24X Market Session.[267]                                          The 24X rule requiring the operation of the Equity Data Plans during the 24X Market Session is designed to ensure that consolidated quotation and transaction data are provided in a manner that is consistent with the existing extended hours sessions on exchanges.                    [268]                      Accordingly, 24X rules are designed to prevent fraudulent and manipulative acts and practices, promote just and equitable principles of trade, foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to and facilitating transactions in NMS stocks, and perfect the mechanism of a free and open market and a national market system.[269]                                          24X rules are also designed to protect                           ( print page 97106)                        investors and the public interest.[270]                                          The 24X rules governing the 24X Market Session will expand the hours of trading available on a national securities exchange, and such trading will be transparent because trading will not occur unless the Equity Data Plans are able to collect, consolidate, process and disseminate consolidated quotation and transaction data during the 24X Market Session (                    *i.e.,*                     between 8 p.m. and 4 a.m. Sunday, Monday, Tuesday, Wednesday, and Thursday nights that precede a U.S. Business Day).[271]                                          The 24X rules for the 24X Market Session will foster competition by introducing another trading venue during these trading hours.[272]                                          Finally, the 24X rules for the 24X Market Session are designed to provide additional investor protections.[273] 

#### a. Effect of 24X Market Session on Market Structure

                    Several commenters raised questions about the potential impact of the 24X Market Session, as originally proposed, on current market structure because it would greatly expand exchange trading hours. Several commenters stated that the Commission should consider roundtable discussions about the market structure implications of 24-hour trading.[274]                                          One commenter stated that the 24X proposal “has serious implications for the regulatory, technological, and operational underpinnings of the equity securities markets and will result in significant costs for the industry.” [275]                                          Another commenter stated that the 24X Market Session, as originally proposed, is “incompatible” with current market structure and that a broader Commission engagement, outside of an exchange application, is needed to determine how U.S. equity market structure would be affected.[276]                                          This commenter further stated that the 24X Market Session as originally proposed “could exacerbate a two-tiered system of regulation between core and extended trading hours” because certain Exchange Act rules apply only during Regular Trading Hours [277]                                          and could make compliance with best execution obligations more challenging.[278]                                          Another commenter stated that the 24X Market Session, as originally proposed “[r]aises significant, insufficiently addressed market policy concerns,” [279]                                          while another stated that the proposal represents the “first occurrence of a national securities exchange that utilizes unlisted trading privileges to operate outside the trading hours of the primary listing exchanges.” [280] 

                    24X stated that “in today's market, the regulatory requirements vary depending on the trading session” with greater protections required during Regular Trading Hours.[281]                                          24X stated that the Commission has allowed extended trading hours on other exchanges and the same rationale should be applied in this instance because the 24X rules for the 24X Market Session raise “no new issues.” [282]                                          In response to the comment about trading NMS stocks pursuant to UTP outside of the hours of the primary listing exchanges, 24X stated that it would “coordinate with the primary listing markets with regard to their regulatory roles related to their listed companies (                    *e.g.,*                     trading halts).” [283]                                          Further, 24X stated that 24X Rule 11.15(c)(5) requires 24X to halt trading if the primary listing exchange determines to halt trading.[284]                                          In response to comments about industry roundtables, 24X stated that “its exchange application has been subject to public comment by the industry and others . . . in accordance with the requirements of the Exchange Act.” [285]                                          24X further stated that amending the rules governing the 24X Market Session to eliminate trading on weekends and holidays in response to comments is a “significant adaption.” [286] 

                    The 24X rules for the 24X Market Session have been amended to increase transparency and enhance customer risk disclosures such that it will operate in a manner that is consistent with the regulatory framework of the extended hours sessions of other national securities exchanges.[287]                                          As discussed throughout this order, the 24X Market Session, as amended, will operate with rules that are designed to protect investors consistent with the requirements of the federal securities laws and the rules and regulations thereunder.                

                    Several commenters suggested that a broader study of expanded hours trading should be conducted prior to Commission action on the 24X exchange application.[288]                                          The continuing evolution of the equities market, including increasing investor interest in extended hours trading, may warrant consideration of the existing regulatory scheme that applies to expanded hours trading sessions. The Commission continually monitors the national market system and the operation of the Federal securities laws, and the Commission, consistent with its oversight of the national market system, will continue to monitor the developments of extended hours trading. However, the monitoring of new market developments does not foreclose Commission action on the 24X Form 1, which, for reasons discussed throughout, satisfies the requirements of the Exchange Act.                
      ( print page 97107)    
                    Further, the 24X Form 1 has been subject to the relevant notice and comment requirements. Public comment on the application has been solicited four separate times—with the publication of the Notice, the OIP, Amendment No. 1, and Amendment No. 2. The public, including market participants, have been afforded adequate opportunity for comment, and interested persons have taken the opportunity to provide written data, views, and arguments concerning this application which has yielded a robust analysis of the relevant issues.[289]                                          24X has responded, by amending its Form 1, in part, to address the various concerns raised by certain commenters. Notably, 24X has narrowed its hours of operation, added rules to increase operational transparency and relevant customer risk disclosures, and amended certain proposed rules to conform with the existing regulatory framework for extended hours trading of other national securities exchanges. In addition, as has been discussed throughout this order, the expansion of trading hours initially proposed by 24X is not entirely novel as off-exchange trading currently occurs during those hours. Accordingly, issues related to the 24X Market Session have been raised, analyzed, and addressed, and Commission action on the 24X Form 1 should not be delayed by, and is not dependent on, a broader study of equity market structure.                

                    While there will be costs to the industry related to implementing the expansion of exchange trading hours, the record does not support a denial of the 24X Form 1 application as inconsistent with the Exchange Act. The operation of the 24X Market Session will not commence until the conditions outlined in this order have been met.[290] 

#### i. Equity Data Plans

                    The Equity Data Plans do not operate during the time period that will cover the 24X Market Session, as amended. Several commenters raised concerns about the lack of consolidated data during the 24X Market Session, as originally proposed.[291]                                          One commenter stated that the 24X trading sessions should align with the operational hours of the Equity Data Plans.[292]                                          Another commenter stated that if 24X was approved without extending the exclusive SIP hours, quotes and trades would not be publicly disseminated in real time and that the delay would be inconsistent with the national market system and significantly reduce market transparency.[293]                                          One commenter stated, in response to the 24X Market Session as originally proposed, that moving to 24-hour on-exchange trading requires deliberate consideration of the market-wide implications of such a move, including the cost and complexity of overhauling the market-wide infrastructure to allow for the publication of quote and trade data by the exclusive SIPs during the proposed overnight and weekend sessions, as measured against its potential benefits.[294]                                          The commenter stated that changing exclusive SIP operations to accommodate the original proposal would amount to a huge undertaking, and that the costs and timeline associated with these changes have not been determined.[295]                                          Moreover, the commenter stated that 24X has neither acknowledged responsibility for funding these changes, nor provided information on its ability to do so.[296]                                          The commenter further stated that the exclusive SIPs would likely incur substantial increased ongoing costs to maintain the originally proposed extended hours, and that neither these costs, which the commenter stated would likely be borne by all exclusive SIP subscribers regardless of whether they participate in overnight or weekend trading, nor their potential benefits, have been determined.[297] 

                    In Amendment No. 2, in response to commenters' concerns about the operation of the 24X Market Session during time periods when the Equity Data Plans are not in operation,[298]                                          24X modified its Rule 1.5(c) and Rule 11.16 to require the concurrent operation of the Equity Data Plans before the operation of the 24X Market Session commences, and that 24X file the 24X Market Session Proposed Rule Change that would serve to provide notice to the Commission and the public of 24X's intention to commence operation of the 24X Market Session. Specifically, 24X Rule 1.5(c) states that 24X will not start operating the 24X Market Session unless the Equity Data Plans “(1) have established a mechanism to collect, consolidate, process and disseminate quotation and transaction information at all times during the 24X Market Session that is equivalent to the mechanism established for Exchange Trading Hours other than the 24X Market Session,” and (2) the Equity Data Plans have notified 24X of their readiness.[299] 

                    24X Rule 1.5(c) requires 24X, prior to commencing the 24X Market Session, to file the 24X Market Session Proposed Rule Change, pursuant to section 19(b) of the Exchange Act and the rules thereunder. The 24X Market Session Proposed Rule Change must be filed with the SEC within 18 months of the SEC's approval of 24X's application for registration as a national securities exchange. If the 24X Market Session Proposed Rule Change is not filed within 18 months of the SEC's approval of 24X's application for registration as a national securities exchange, the Exchange will promptly file a proposed rule change to remove the rules that apply to the 24X Market Session. In addition, 24X Rule 11.16 states that, “24X will not commence operations of the 24X Market Session until a proposed rule change as required under 24X Rule 1.5(c) has been approved, or has otherwise become effective, under section 19(b) of the Exchange Act and the rules thereunder.” [300] 

                    24X responded to commenters' concerns about costs by stating that it recognized that innovations, such as the introduction of the 24X Market Session, “may involve additional costs” but that increased costs should not “be the basis for the Commission to determine that an exchange application does not comply with the Exchange Act.” [301]                                          24X stated that market participants “are already trading overnight on ATSs or                           ( print page 97108)                        otherwise” and that new costs for exchange trading would be “incremental.” [302]                                          24X also stated that broker-dealers can decide whether to participate in the 24X Market Session.[303]                                          Finally, 24X stated with regard to the expansion of the exclusive SIPs' hours that the Equity Data Plans have a process for determining the cost for new participants and for changes.[304] 

                    The Commission agrees with commenters regarding consolidated quotation and transaction information during the 24X Market Session. Pursuant to its amended Form 1, 24X will not operate during the 24X Market Session until the Equity Data Plans are able to collect, consolidate, process and disseminate quotation and transaction information at all times during the session. The 24X rules for the 24X Market Session, as amended, are consistent with sections 6(b)(5) and 11A of the Exchange Act.[305] 

24X Rules 1.5(c) and 11.16 provide that 24X will submit a proposed rule change within 18 months of the Commission's approval of 24X's application to operate as a national securities exchange with regard to the operation of the 24X Market Session. These provisions relating to the force and effect of the 24X Market Session rules set forth in 24X Rule 11.16 help to balance the interest in providing the time needed for 24X to be able to comply with 24X Rule 1.5(c) with the interest in ensuring that the rules of an Exchange are effective and can be enforced by the Exchange.

                    The requirement contained in its rules that the 24X Market Session will not begin operation until the 24X Market Session Proposed Rule Change is approved or otherwise has become effective will enhance transparency during the 24X Market Session and promote the goals of the national market system. Specifically, the Commission finds that the 24X rules for the 24X Market Session, as amended, are consistent with section 11A(a)(1)(C) of the Exchange Act, in which Congress found that it is in the public interest and appropriate for the protection of investors and the maintenance of fair and orderly markets to assure the availability to brokers, dealers, and investors of information with respect to quotations for and transactions in securities, and to assure the practicability of brokers executing investors' orders in the best market.[306]                                          The requirement ensuring that 24X will not commence operation of its 24X Market Session until the availability of the concurrent operation of the Equity Data Plans accomplishes Exchange Act objectives by ensuring that there is transparency during these new, extended trading hours through the communication of quotations and transactions to market participants and investors.                

                    Finally, one commenter stated that the Market Data Infrastructure (“MDI”) Rules [307]                                          should be implemented because competing consolidators would not be “time-bound” and would collect, consolidate and disseminate data “in real-time 24/7.” [308]                                          The MDI Rules continue to be implemented, however, the MDI Rules will not be implemented before action is required on the 24X Form 1.[309] 

#### b. Volatility Moderators in the 24X Market Session

                    24X initially proposed to implement unique “24X Price Bands” to moderate risk and volatility during the 24X Market Session.[310]                                          Several commenters questioned the use of the proposed volatility moderators.[311]                                          In particular, one commenter asked why the proposed 24X Price Bands differed from the existing Limit up-Limit down bands and stated that the proposed 24X Price Bands were “different from price bands used by ATSs that operate outside of core trading hours,” [312]                                          while another commenter stated there was no basis to justify the 24X Price Bands.[313]                                          Another commenter, however, stated that the proposed 24X Price Bands “should be sufficient to prevent erroneous trades.” [314] 

                    24X proposed in Amendment No. 1 to remove proposed 24X Rule 11.15(a) from its rules, which removed all references to the proposed 24X Price Bands.[315]                                          In its letter responding to comments on the OIP, 24X stated that it “would rely upon its clearly erroneous rule, [p]roposed 24X Rule 11.14, to address volatility and risk during the 24X Market Session.” [316]                                          24X stated that it would also “provide other additional protections to investors to address potential volatility and risk during the 24X Market Session. For example, under Proposed 24X Rule 11.7(a)(4), 24X would not allow the use of market orders during the 24X Market Session.” [317]                                          As a result, 24X stated that its rules designed “to address potential volatility in both regular and extended hours trading” are the same as those previously approved by the Commission for other exchanges.[318] 

                    One commenter stated that given the significance of displayed quotations and transaction prices to stock valuations, many trading firms and other participants will need to monitor the prices published during overnight and weekend hours, regardless of whether they trade during those hours and that “SIP subscribers” would experience “costs.” [319]                                          This commenter also stated that “[t]his is particularly the case” because 24X does not include volatility limits other than those that exist under its clearly erroneous execution rule.[320]                                          Another commenter opposed 24X's plan to rely on its clearly erroneous execution rules instead of price bands, as initially proposed.[321]                                          This commenter stated that the Commission should consider “whether the regulatory framework and market functionality are in place to support 24x7 trading (including, for example, whether extending the LULD plan to cover non-core hours is appropriate).” [322] 
      ( print page 97109)    
                    24X's proposed use of its clearly erroneous execution rule during the 24X Market Session addresses commenters' concerns about its initially proposed 24X Price Bands. The use of clearly erroneous execution rules in the 24X Market Session, instead of the unique, market-specific 24X Price Bands, will help to ensure there is a consistent, market-wide regulatory approach across the extended hours trading sessions of all national securities exchanges.[323]                                          Accordingly, 24X Rule 11.14 is designed to facilitate transactions in securities and remove impediments to and perfect the mechanism of a free and open market and a national market system, consistent with section 6(b)(5) of the Exchange Act.                

                    While one commenter suggested that “SIP subscribers” may experience increased costs due to the need to monitor prices during the 24X Market Session, the commenter did not provide information as to how this differs from other extended hour trading sessions and the commenter was commenting on the 24X Market Session as originally proposed. As amended by Amendment No. 2, the 24X Market Session would cover hours that are currently available for OTC trading and 24X may not begin operating its 24X Market Session at least until the Equity Data Plans are able to collect, process, consolidate and disseminate quotation and transaction data during the 24X Market Session,[324]                                          which will help to facilitate monitoring of price valuations. Further, as stated above, the use of clearly erroneous execution rules in extended hours sessions is consistent with the regulatory framework applied to other national securities exchanges.[325] 

#### c. Trading Halts and Pauses

                    24X proposed rules governing trading halts and pauses for technology updates and regulatory purposes. As originally proposed, 24X Rules 11.15(c)(1), (c)(2), (c)(3), (c)(4) and (c)(5) would have paused trading for: (i) three hours each Saturday morning, from 8 a.m. until 11 a.m.; (ii) an hour at 7 p.m. daily; (iii) industry-wide testing; (iv) technological or other purposes; and (v) material corporate actions with respect to a particular security during the 24X Market Session, respectively. In Amendment No. 2, 24X deleted 24X Rules 11.15(c)(1) and 11.15(c)(3) and amended 24X Rule 11.15(c)(2), all to reflect the amended hours for the 24X Market Session. Pursuant to 24X Rule 11.15(c), 24X will pause trading on Monday, Tuesday, Wednesday and Thursday at 7 p.m.,[326]                                          during the 24X Market Session at such other times that the Exchange determines is necessary for technological or other purposes,[327]                                          and if the primary listing exchange determines to halt trading or delay the start of trading in one of its listed securities.[328] 

                    With respect to regulatory halts, several commenters questioned how market surveillance and trading halts, including regulatory trading halts, would be handled in the 24X Market Session.[329]                                          Specifically, one commenter stated that 24X's proposal raised a series of surveillance questions, including (i) how 24X will manage real-time surveillance during the 24X Market Session, (ii) how the existing surveillance, trading halt, and trade review infrastructure—one in which primary listing markets perform real-time surveillance of securities listed on their markets and implement trading halts and pauses for those securities during their hours of operation—will intersect with the proposed 24X Market Session, including how 24X would coordinate with other exchanges, and (iii) the impact that such trading will have on investors, listed companies, and other market participants.[330]                                          Similarly, other commenters expressed concerns about regulatory halts, including possible unanticipated or unintended effects on primary listing markets and issuers.[331]                                          One of these commenters stated that the expanded trading hours would interfere with exclusive SIPs' “periodic testing and maintenance, which currently occur at times when the exchanges are closed.” [332]                                          Another commenter generally supported the proposed trading halts but recommended that 24X “revisit trading halts around key disclosures from companies” if “they find they can adequately secure the markets around the key disclosure periods.” [333] 

                    In response to commenters' concerns about regulatory halts,[334]                                          24X stated that it intends to surveil all of its trading sessions, including the 24X Market Session, in the same manner.[335]                                          24X stated that it will coordinate with the primary listing markets to halt trading in a security when the primary listing market halts trading in the security.[336]                                          In addition, in Amendment No. 1, 24X proposed to revise its trading halt rules related to the primary listing market to clarify that Rule 11.15(c)(5) will apply during all of its trading sessions.[337]                                          Specifically, 24X proposed to add language to 24X Rule 11.15(c)(5) that if trading in a security is halted by the primary listing market before the 24X Market Session and continuing into the 24X Market Session, or during the 24X Market Session, the Exchange will halt trading in the security until trading resumes on the primary listing market for the security.[338] 

                    24X's rules, as amended, governing trading halts related to corporate news and announcements will track the trading halts imposed by the primary listing markets. To the extent that material corporate news is released during the 24X Market Session and the primary listing market does not impose trading halts, the requirements of 24X Rule 3.21(e) [339]                                          and 24X Rule 3.21(i) [340]                                          that disclosures be provided to investors relating to the risks associated with news announcements and the additional risks of trading in the 24X Market Session, respectively, will help to ensure that market participants, including investors, are informed about the potential risks associated with trading during that time period. 24X's rules governing trading pauses, coupled with its Rule 3.21,[341]                                          are consistent with the Exchange Act and, in particular, the section 6(b)(5) requirement that an exchange's rules be designed to promote                           ( print page 97110)                        just and equitable principles of trade, remove impediments to and perfect the mechanisms of a free and open market and a national market system, and protect investors and the public interest.                

                    Regarding technology halts, one commenter on the 24X Market Session, as originally proposed, stated that testing for the exclusive SIP of the UTP Plan currently occurs at times which would overlap “with a portion of the 24X Market Session, and 24X has not explained how it will operate during the overlapping time.” [342]                                          In Amendment No. 2, 24X has amended the 24X rules for the 24X Market Session to exclude trading on weekends. This amendment addresses concerns about conflicts with industry-wide testing, “which currently occur[s] at times when the exchanges are closed.” The trading pauses provided in 24X Rule 11.15(c), as amended [343]                                          should be sufficient to permit 24X to address the technical implications of a 23-hour trading day and will facilitate industry-wide testing, and internal market testing and systems updates and improvements.                

#### d. Securities Eligible for Trading During the 24X Market Session

                    In its initial Form 1, 24X proposed to limit the securities that would be available for trading during the 24X Market Session. Specifically, proposed 24X Rule 11.2 specified that any class of securities listed or admitted to unlisted trading privileges on the Exchange would be eligible to be traded during the Pre-Market Session, Core Market Session and Post-Market Session, while in the 24X Market Session, trading would be limited to any security in the Nasdaq-100 Index, S&P 500 Index, Russell 2000 Index and the top 50 exchange-traded funds by average daily volume during a given month, as determined by the Exchange. Proposed 24X Rule 11.2 also included a notice provision for securities that might be added to, or removed from, being eligible to trade during the 24X Market Session. Finally, proposed 24X Rule 11.2 initially would have allowed Exchange members to request that securities be made eligible for trading during the 24X Market Session.[344] 

                    One commenter stated that the proposal was “wise in limiting the trading to certain well-known NMS stocks.” [345]                                          Another commenter stated that 24X did not adequately justify its proposal to limit the securities eligible for trading in the 24X Market Session.[346]                                          Another commenter stated that 24X should provide more transparency about the proposed notice of securities that would be available to trade because the commenter stated that a “lack of timely information” about the securities available to trade “runs the risk of material trading risks, including higher volatility and lower liquidity.” [347] 

                    In Amendment No. 1, 24X amended 24X Rule 11.2 to remove the limit on the securities eligible for trading during the 24X Market Session. As amended, 24X Rule 11.2 will allow any securities listed or admitted to trading pursuant to UTP to be eligible to trade on 24X. In other words, 24X Rule 11.2 was amended to make the eligibility requirements for the trading of securities during the 24X Market Session the same as the other three market sessions (                    *i.e.,*                     Pre-Market Session, Core Market Session and Post-Market Session). According to 24X, expanding the securities eligible to trade during the 24X Market Session will allow 24X Members and their customers to manage their security lists, and ensure continuity of eligible securities across trading sessions, which will reduce potential trading complexities and investor inquiries about eligible securities.[348]                                          24X also stated that expanding the securities eligible to trade will allow it to compete with ATSs and other markets that operate in the overnight hours.[349]                                          Finally, 24X stated that the amended rule will prevent the exclusion of securities that may be appropriate for trading in the 24X Market Session, such as international ETFs.[350] 

                    24X Rule 11.2 as amended, is consistent with section 6(b)(5) of the Exchange Act in that it will promote just and equitable principles of trade, facilitate transactions in NMS stocks, remove impediments to, and facilitate transactions in NMS stocks and remove impediments to and prefect the mechanism of a free and open market and a national market system. While one commenter supported limiting the securities eligible for trading in the 24X Market Session,[351]                                          24X's market structure choice not to limit the securities eligible for trading in the 24X Market Session will reduce the complexity of the 24X market structure, compared to the original proposal, by allowing securities to be eligible continuously throughout the four 24X trading sessions. In addition, 24X Members and their customers will have control over the trading strategies they may choose to implement. Finally, expanding the number of securities that are eligible to be traded during the 24X Market Session should help to promote competition between trading venues that may be operating during the times covered by the 24X Market Session, which will ultimately benefit investors.                

#### e. Customer Disclosures Pertaining to Extended Hours Trading, Including the 24X Market Session

                    24X proposed to require that 24X Members make certain disclosures to investors concerning risks associated with trading during Extended Hours Trading.[352]                                          In 24X Rule 3.21, 24X proposed to require the same disclosures as those required by other SROs relating to extended hours trading.[353]                                          Specifically, SRO rules require firms to provide disclosures to customers that extended hours trading “involves material trading risks, including the possibility of lower liquidity, high volatility, changing prices, unlinked markets, an exaggerated effect from news announcements, wider spreads.” [354] 

                    While one commenter stated, in response to a question posed by the Commission in the OIP, that the proposed disclosures would be                           ( print page 97111)                        sufficient to highlight the unique risks posed to investors during the 24X Market Session, as originally proposed,[355]                                          others disagreed.[356]                                          One of these commenters stated that existing customer disclosures would not provide the necessary protection for investors given the heightened risks associated with the 24X Market Session.[357]                                          Similarly, another commenter stated that it cannot “comprehend how any disclosure that would be sufficiently short and clear to be comprehensible would adequately capture the sheer volume of potential new risks or regulatory gaps in which such trading would occur.” [358] 

                    In response, 24X stated that it agreed with commenters that it is appropriate to require customer disclosures relating to the “heightened” risks inherent in Extended Hours Trading.[359]                                          In Amendment No. 1, 24X proposed “expanded” investor disclosures relating to additional potential risks of its 24X Market Session.[360]                                          Specifically, the new paragraph (i) added to 24X Rule 3.21 will highlight the following additional potential risks related to trading during the 24X Market Session, including the risks that: (1) the primary listing markets may not be open; (2) consolidated market data may not be available; (3) there may be limited or different regulatory protections during the 24X Market Session; (4) there may be limited trading alternatives during the 24X Market Session; (5) with near continuous trading, there may be greater risk related to system maintenance, testing and pauses and resumption in trading; and (6) the 24X Market Session is novel and may present additional unforeseen risks in addition to those discussed above.[361]                                          In Amendment No. 2, 24X amended 24X Rule 3.21 to remove the disclosure related to the risk that consolidated data may not be available because pursuant to amended 24X Rule 1.5(c), 24X will not begin operation of its 24X Market Session unless the exclusive SIPs are able to concurrently collect, consolidate, process and disseminate consolidated data.[362]                                          Thus, the proposed disclosure stating the risk that there might not be information disseminated by the exclusive SIPs during the 24X Market Session is no longer necessary.                

The expanded proposed customer disclosures set forth in 24X Rule 3.21, as amended, should address commenters' concerns because these disclosures will provide investors with important information that should help to inform their decisions as to whether trading during extended hours, including the 24X Market Session, is suitable for them. In addition, the expanded customer disclosures set forth in 24X Rule 3.21, as amended, are consistent with the Exchange Act and, in particular, the section 6(b)(5) requirement that an exchange's rules be designed to promote just and equitable principles of trade, remove impediments to and perfect the mechanisms of a free and open market and a national market system, and protect investors and the public interest. The disclosures will help provide notice to market participants, including investors, about the specific risks associated with Extended Hours Trading.

#### f. Other Comments

24X proposed 24X Rule 11.12 related to the clearance and settlement of trades. Under this rule, 24X will require that all transactions through the facilities of the Exchange be automatically cleared and settled through a registered clearing agency using a continuous net settlement system when the continuous net settlement system is open. When the continuous net settlement system is closed, 24X will require trades to be processed for clearing and settlement as soon as the relevant clearing agency reopens the continuous net settlement system.

                    One commenter questioned the settlement cycle of trades in the context of the 24X Market Session, as originally proposed.[363]                                          The commenter stated that a trade executed at 11:59 p.m. would settle the next day and a trade that executed just two minutes later, at 12:01 a.m., would not settle until the following day (assuming consecutive settlement dates).[364]                                          The commenter also stated that the 24X Market Session, as originally proposed, raises additional operational and risk management questions related to the clearance and settlement processes for trades that occur overnight and on non-business days operated by registered clearing agencies, including the National Securities Clearing Corporation (“NSCC”).[365]                                          In its second letter, the commenter stated that all default risks and related clearance, settlement, payment and delivery risks would be borne by broker-dealers until trades were transferred to DTCC for novation, which would impose significant counterparty risk on broker-dealers.[366]                                          The commenter stated that retail investors “would be unaware” that trades executed during the 24X Market Session would be excluded from the NSCC and DTCC's real-time guarantee model.[367]                                          The commenter stated that delays in reporting overnight trades to NSCC also impact margin requirements, including margin calculations.[368] 

                    24X responded that the commenter's concerns related to the clearance and settlement of trades “have long existed and are contemplated within existing NSCC/DTCC rules.” [369]                                          24X also stated that it understood, from the DTCC, that the operational and clearance and settlement risks related to its proposed overnight and weekend trading are manageable using existing risk management rules and protocols,[370]                                          and that “DTCC plans to implement additional changes to its processes going forward to further narrow the risks presented by extended trading hours.” [371]                                          Further, 24X stated that trades occurring within a matter of                           ( print page 97112)                        minutes that could settle on different days is a “natural outgrowth” of the T+1 settlement process because there must be a time that delineates the end of a trading day.[372]                                          Finally, 24X stated that, “as with overnight trading on ATSs today, broker-dealers concerned about potential operational and clearance and settlement risks related to such trading are not required to trade in the 24X Market Session.” [373] 

                    The 24X rules related to clearance and settlement of transactions on 24X are consistent with the requirements of section 6(b)(5) of the Exchange Act that provides, among other things, that the rules of an exchange must foster cooperation and coordination with persons engaged in regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities.[374]                                          Further, the Commission concludes that while risk cannot be eliminated, it can be appropriately managed as it relates to: (1) the proposed operation of the 24X Market Session and (2) the ability of the relevant clearing agencies for equities, NSCC and the DTC, to address any potential credit, market, and liquidity risks associated with trades submitted by the Exchange. While one commenter submitted several interpretative questions related to how clearance and settlement of trades will occur during the 24X Market Session, the commenter did not explain how the clearance and settlement of 24X Market Session trades would be different from trades that occur in the overnight sessions in the OTC market.[375]                                          Further, the commenter stated that broker-dealers will carry all default risks and related clearance, settlement, payment and delivery risks until trades are reported. Broker-dealers may assess the risks and benefits of participating in the 24X Market Session. Although a commenter stated that investors would be unaware of the risks held by broker-dealers, 24X Rule 3.21(g) requires disclosure of the risk that certain financial market infrastructure, including “the relevant clearing agency” and “certain other providers of settlement services,” may be closed for business during the Extended Hours Trading sessions. Finally, the concerns of certain commenters about weekend trading are no longer relevant because 24X has amended its rules to eliminate weekend trading.                

24X proposed several rules that are reasonably designed to ensure compliance with Regulation SHO. 24X Rule 11.9(a)(1) requires the execution price of an order with short sale instruction to be above the current national best bid if a short sale price test restriction under Rule 201 is in effect, unless the order is marked short exempt; and 24X Rule 11.9(a)(5) requires all orders to sell short to include a short sale instruction. 24X Rule 11.23 relates to Short Sale Circuit Breakers and sets forth that once a Short Sale Circuit Breaker pursuant to Rule 201 of Regulation SHO has been triggered during Regular Trading Hours, the price test restriction of Rule 201 will be in place for the applicable covered security for the remainder of the trading day on which the Short Sale Circuit Breaker is triggered, through the next U.S. Business Day after the trading day on which the Short Sale Circuit Breaker is triggered, and until 4 a.m. on the U.S. Business Day after the next U.S. Business Day after the trading day on which the Short Sale Circuit Breaker is triggered, unless the listing market for the covered security provides a notification via the exclusive SIPs indicating that the price test restriction is no longer in effect at a time earlier than 4 a.m. on the U.S. Business Day after the next U.S. Business Day after the trading day on which the Short Sale Circuit Breaker is triggered. 24X Rule 13.2 requires borrowing and deliveries to be effected in accordance with Rule 203 of Regulation SHO and provides that the 24X incorporates by reference Rules 200 and 203 of Regulation SHO.

                    One commenter questioned how would compliance with the circuit breaker requirements set forth in Rule 201(b)(1)(ii) of Regulation SHO be achieved if the exclusive SIPs were not in operation during the 24X Market Session.[376]                                          The commenter also stated that the close-out requirement for the failure to deliver, set forth in Rule 204 of Regulation SHO, could be delayed due to the extension of trading hours to non-business days.[377]                                          24X responded that it would comply with Rule 201 of Regulation SHO whenever it is deemed to apply.[378] 

                    The 24X rules are consistent with the Exchange Act as they incorporate Regulation SHO requirements. Accordingly, 24X rules are consistent with section 6(b)(5) of the Exchange Act because they are designed to prevent fraudulent and manipulative acts and practices and promote just and equitable principles of trade. Further, in response to commenter's concerns about potential delays in the close out requirement due to the initially proposed 24X Market Session operating during non-business days,[379]                                          the 24X Market Session, as amended, will not provide for trading on non-U.S. Business Days. In response to the question raised by the commenter about compliance with the circuit breaker requirements if the exclusive SIPs were not in operation, in Amendment No. 2, 24X amended the rules governing the 24X Market Session so that 24X will not commence operations of the 24X Market Session until the Equity Data Plans are able to collect, consolidate, process and disseminate consolidated data during the 24X Market Session designated hours.[380] 

                    24X proposed 24X Rule 11.13 governing 24X's limitation of liability arising from use of Exchange systems or facilities.[381]                                          Two commenters commented on 24X's rule.[382]                                          One commenter stated that 24X failed to appropriately justify its proposed limitation of liability.[383]                                          This commenter stated that 24X's limitation of liability provision is modeled on a similar provision adopted in 2005 and that subsequent significant equity market structure changes have rendered the proposed provision inadequate, particularly given the 24X Market Session, as originally proposed.[384]                                          One of these commenters further stated that 24X provides no support for the Commission to find the limitation of liability provisions consistent with the Exchange Act or the public interest, and that “[a]n even greater level of scrutiny regarding the proposed 24X limitation of liability is warranted due to the additional operational risks associated with operating a near 24x7 market center.” [385]                                          The other commenter stated that “[n]otably, 24X intends to operate for significantly more trading hours and trading days than other national securities exchanges, and it has not explained why the liability caps                           ( print page 97113)                        included in its proposed rule are reasonable or appropriately tailored to address the risk of system errors or malfunctions on its market across these longer periods.” [386] 

                    In response to the commenter's concerns, 24X stated that it believes that the 24X rule complies with the Exchange Act.[387]                                          24X continued that other exchanges operate pursuant to the “same rule” and that “there is no basis for reaching a different conclusion in the context of 24X's Form 1 application.” [388]                                          24X also stated that “the liability caps were not established based on the number of trading hours on the exchange.” [389] 

                    The limitation of liability provisions of 24X Rule 11.13 are consistent with the Exchange Act requirement that the rules of an exchange be designed to promote just and equitable principles of trade and not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act.[390]                                          24X Rule 11.13 is substantively similar to other exchanges' limitation of liability provisions previously approved by the Commission and applicable to other exchanges that have extended hours trading sessions.[391]                                          In addition, with respect to the commenters' statements that greater exchange liability would be appropriate given the “additional operational risks associated with operating a near 24x7 market center,” 24X will be required to comply with its obligations under the Exchange Act during all hours that it is operating. While 24X has more hours of operations as compared to other exchanges, 24X will have SRO obligations during the 24X Market Session as it does during its other trading sessions. Further, as discussed below, 24X will be an SCI entity that must comply with Regulation SCI.[392]                                          While commenters submitted comments on the 24X Form 1, both commenters stated that the limitation of liability caps on all exchanges should be reevaluated. As stated above, the Commission, consistent with its oversight of the national market system, will continue to monitor the national market system. However, the monitoring of market developments does not foreclose Commission action on the 24X Form 1, which for reasons discussed throughout, satisfies the requirements of the Exchange Act.                

                    One commenter requested interpretative guidance on the application of Commission Rule 605 and Rule 610(d) and FINRA Rule 5320.08 to the proposed 24X trading sessions (                    *i.e.,*                     Pre-Market Session, Post-Market Session, 24X Market Session and Core Market Session).[393]                                          These rules are clear as to their application during different sessions and the commenter did not state why the 24X Form 1 raised unique interpretative questions compared to the extended hours sessions on other national securities exchanges that have operated for several years.                

### E. Technology Agreement With MEMX Technology

#### 1. Delivery, Licenses and Services Agreement (“DLSA”)

                    The Exchange will utilize trading technology and systems (collectively, the “Technology and System”) developed by MEMX Technologies, LLC (“MEMX Technologies”),[394]                                          a subsidiary of MEMX Holdings LLC, and provided to the Exchange pursuant to a DLSA between MEMX Technologies and the Exchange.[395]                                          Specifically, pursuant to the DLSA, MEMX Technologies will provide technology support services to 24X, which will include “(1) the development and testing of software and hardware necessary to operate the matching engine and connectivity to other exchanges via a third-party routing broker(s) and third party-developed functions (including clearing, custody, and client connectivity), (2) the provision of technical support in order for the Exchange to operate and monitor the Exchange; and (3) the provision of ongoing system availability commitments, updates, fixes, and technology support.” [396]                                          MEMX Technologies will support intra-day compliance monitoring by 24X and provide timely reporting to 24X of any potential Regulation SCI events or other operational issues with the System.[397] 

                    All services provided to the Exchange by MEMX Technologies will be based upon requirements and instructions determined by the Exchange.[398]                                          Although MEMX Technologies would provide the technology support services, 24X will be responsible for operating and monitoring its Exchange-related Technology and System and administering the rules of the Exchange and other rules and regulations applicable to the Exchange.[399]                                          To ensure logical and physical separation from MEMX Technologies and its affiliates, the Technology and System will operate a separate instance of MEMX Technologies' core matching engine technology and software, utilizing separate servers from the MEMX Exchange system and separate connections for 24X Members to connect to 24X.[400]                                          Under the terms of the DLSA, 24X may request MEMX Technologies to develop and implement (for a fee to be determined by the parties) technology changes that change the operation of the 24X Technology and System. 24X is not obligated to agree to, accept, or adopt changes to the Technology and System that are not essential to the operation of its instance of the Technology and System.[401]                                          Additionally, 24X stated that the “trading platforms operated by MEMX Technologies (including 24X National Exchange, LLC, MEMX Exchange, and any other exchanges or trading platforms operated by MEMX Technologies) currently are and will be segregated to ensure that 24X is not deemed to be a facility of MEMX Exchange.” [402]                                          MEMX Technologies will not use or disclose information or data (i) about or originating with 24X in its dealings with MEMX Exchange or any other platform or (ii) about or originating with MEMX Exchange or any other platform in its dealing with 24X.[403] 
      ( print page 97114)    
                    One commenter stated that the proposal by 24X to outsource its technology needs, along with the maintenance and remediation of technology issues, to MEMX Technologies “is distinct from the existing common practice of exchanges and other venues to outsource discrete technology elements to individual vendors based on the expertise provide by each vendor, subject to oversight of the vendors by the exchange as required by Regulation SCI.” [404]                                          The commenter further stated that other “existing examples do not involve exclusive reliance on a single technology provider (affiliated with one exchange) for multiple U.S. registered exchange[s].” [405] 

                    This commenter's statements were disputed by another commenter, who stated that “having a common technology platform underlying multiple registered exchanges is hardly a new phenomenon. Of the sixteen currently licensed U.S. equities exchanges, twelve are operated by just three exchange groups that each operate several independently-registered exchanges using a common technology platform.” [406]                                          The commenter further stated that use of vendors “allows competitors of all sorts to focus on their core business, whether that's facilitating the move to a 24-hour trading model, . . . or in attracting listings from corporate issuers.” [407]                                          24X responded that “the use of a common technology platform for multiple registered exchanges is a common practice. 24X understands that three existing exchange groups operate several independently-registered national securities exchanges using a common technology platform.” [408]                                          The Commission agrees that the outsourcing of an exchange's technology platform to another entity is not novel.[409] 

                    Two commenters stated that there should be greater clarification on the relationship between 24X and MEMX Technologies.[410]                                          A third commenter expressed concerns about the proposed agreement between 24X and MEMX Technologies.[411]                                          One of these commenters stated that the Exchange would be heavily dependent on MEMX Technologies, and asked whether MEMX Technologies would be more properly viewed as an owner or control person for its technology needs.[412]                                          As the Commission stated above, MEMX Technologies is a vendor that will provide technology support services to 24X, to meet requirements established by 24X; MEMX Technologies has no ownership interest in 24X.[413]                                          The ultimate responsibility for regulatory compliance with the Exchange Act and rules thereunder falls on 24X as the SRO. Nor will MEMX Technologies be able to assert control over 24X regarding operation of the Technology and System. Under the terms of the DLSA, as described in the Form 1, 24X is not obligated to agree to, accept, or adopt changes to the Technology and System that are not essential to the operation of its instance of the Technology and System.[414] 

                    Another commenter stated that the “exclusive reliance on a single vendor raises questions about the availability of resources by [MEMX Technologies] to fill that role.” [415]                                          Similarly, one commenter asked for clarification as to whether MEMX Technologies “has the staff and infrastructure to facilitate 23-hour continuous trading” [416]                                          and stated that there should be “a detailed reassurance that the technology underlying the exchange will not breakdown due to a high user rate and further if the technology does fail, what the procedures will be to protect the exchange while also safeguarding investors information and portfolios.” [417]                                          24X in response stated that the technology it will utilize “has a proven track record for resiliency, a track record that should give the SEC and market participants comfort regarding the reliability of 24X's market offering.” [418] 

                    Another of the commenters stated that 24X's potential use of MEMX Technologies for operational support raises conflicts concerns and that the Form 1 “contains little if any information about management of conflicts more generally.” [419]                                          This commenter stated that there are no statements or information about the “nature and extent” of the segregation between 24X and MEMX Technologies or the “financial terms of 24X's agreement with [MEMX Technologies] and about what type of separation may exist between [MEMX Technologies] and MEMX.” [420]                                          The commenter further stated that its concerns “may be magnified to the extent that other exchanges propose to make use of this same exclusive `white label' technology solution by the same vendor to meet their technology needs, as has been widely reported. Under that construction, [MEMX Technologies] would appear to be performing in effect a technology utility function for multiple regulated exchanges, but it                           ( print page 97115)                        would not be a regulated entity itself, and the Commission would have limited ability to evaluate, and no ability to control, how it performs that critical function.” [421] 

                    24X, not MEMX Technologies, has regulatory responsibility over the 24X System, and therefore 24X as a SRO is fully responsible for discharging its obligations as a registered national securities exchange. The Commission disagrees with the commenter that the Form 1 contains little information about these matters.[422]                                          24X has provided sufficient detail in the Form 1 regarding the relationship between 24X and MEMX Technologies.[423]                                          MEMX Technologies will not use or disclose information or data (i) about or originating with 24X in its dealings with MEMX Exchange or any other platform or (ii) about or originating with the MEMX Exchange or any other platform in its dealings with 24X.[424]                                          Also, the DLSA, among other things, enforces logical and physical separation from MEMX Technologies and its affiliates in that the Technology and System will operate a separate instance of MEMX Technologies' core matching engine technology and software, utilizing separate servers from MEMX Exchange system and separate connections for Members to connect to 24X.[425]                                          Further, 24X will interact with the MEMX Exchange, including MEMX Exchange's routing broker-dealer, on the same arms-length commercial terms as 24X interacts with other registered national securities exchanges and their routing broker-dealers.[426]                                          Membership in the MEMX Exchange will not confer any advantages when trading on 24X (or vice versa), such as faster connections, lower fees, or preferential treatment of orders on the 24X System.[427]                                          Membership in the MEMX Exchange will also not be a requirement for membership in or connection to 24X (or vice versa).[428] 

                    After consideration of the disclosures 24X made in its Form 1 application and review of the comments, the Commission finds that 24X's proposal to utilize technology provided and maintained by MEMX Technologies is consistent with the Exchange Act, in particular with section 6(b)(1) of the Exchange Act,[429]                                          which requires an exchange to be so organized and have the capacity to carry out the purposes of the Exchange Act and to comply and enforce compliance by its members and persons associated with its members with the Exchange Act and the rules thereunder. The arrangement between 24X and MEMX Technologies, as described in the 24X Form 1, will enable the Exchange to utilize trading platform technology that is already in use with an experienced operator.[430]                                          However, the terms of the DLSA between 24X and MEMX Technologies, as described in the Form 1, are reasonably designed not to confer upon either MEMX Exchange or 24X Members any advantages when trading on 24X, or vice versa, such as faster connections, lower fees, or preferential treatment of orders on the 24X System.[431]                                          Further, as described in the Form 1, the DLSA will not include the technology or systems to route orders to the MEMX Exchange or any other exchange.[432]                                          24X will retain responsibility for overseeing the daily market operations of its trading system; MEMX Technologies will be responsible for performing all necessary maintenance and remediation of problems relating to the logical and physical infrastructure, in accordance with the DLSA.[433]                                          Therefore, 24X will be capable of exercising sufficient control over the operation of its Technology and System, and will be sufficiently independent from MEMX Technologies, to enable 24X to comply with the requirements under the Exchange Act and the rules thereunder.                

                    The provisions of the DLSA described above demonstrate that the support services provided by MEMX Technology are adequate to enable 24X to meet its self-regulatory obligations. In order for 24X to perform its regulatory obligations, the DLSA provides 24X with enumerated audit rights to review books and records of MEMX Technologies related to the provision of services under the DLSA, and the ability either to produce itself, or direct MEMX Technologies to produce, MEMX Technologies documents and information related to the operation of the Technology and System to the Commission or other regulators or parties upon request, subject to appropriate due process.[434] 

                    Finally, 24X will have regulatory responsibility for its trading Technology and System and will be responsible to fully discharge its obligations as a national securities exchange. 24X will also be responsible for its market and cross-market surveillance through the RSA, described above,[435]                                          and maintain its independent regulatory function to oversee the RSA and will not rely on or utilize MEMX Exchange or its personnel to fulfill any aspect of those obligations on 24X's behalf.                

#### 2. Regulation SCI

                    As a registered national securities exchange, 24X will be an “SCI entity” responsible for compliance with the requirements of Regulation Systems Compliance and Integrity (“Regulation SCI”).[436]                                          Regulation SCI requires SCI entities to establish written policies and procedures reasonably designed to ensure that their applicable systems have levels of capacity, integrity, resiliency, availability, and security adequate to maintain their operational capability and promote the maintenance of fair and orderly markets, and that they operate in a manner that complies with the Exchange Act.[437]                                          In addition, Regulation SCI requires SCI entities to take corrective action with respect to SCI events (defined to include systems disruptions, systems compliance issues, and systems intrusions), notify the Commission of such events, and disseminate information about certain SCI events to affected members or participants (and, for certain major SCI events, to all members or participants of the SCI entity).[438]                                          Moreover, Regulation SCI requires SCI entities to conduct a review of their systems by objective personnel at least annually, submit quarterly reports regarding completed, ongoing, and planned material changes to their SCI systems to the Commission,[439]                                          and maintain certain books and records.[440]                                          It also requires SCI entities to mandate participation by designated members or participants in scheduled testing of the operation of their business continuity and disaster recovery plans, including backup systems, and to coordinate such testing                           ( print page 97116)                        on an industry- or sector-wide basis with other SCI entities.[441] 

                    Regulation SCI applies to an SCI entity's “SCI systems,” which are systems that directly support any one of six key securities market functions—trading, clearance and settlement, order routing, market data, market regulation, and market surveillance (“SCI systems”). Regulation SCI also applies to “indirect SCI systems,” which are any systems that, if breached, are likely to pose a security threat to SCI systems. Further, certain SCI systems that are “critical SCI systems” are held to certain heightened requirements under Regulation SCI.[442] 

                    The Exchange has obtained commitments from MEMX Technologies in connection with the Exchange's engagement of MEMX Technologies to develop, license, and operate the Technology and System on behalf of the Exchange to, among other things, address how this arrangement is consistent with the requirements of Regulation SCI.[443]                                          The Exchange acknowledges that as the SCI entity contracting with MEMX Technologies to provide software and hardware to operate both SCI systems and indirect SCI systems, 24X will have full responsibility for ensuring that it is in compliance with all aspects of Regulation SCI, including the requirements for its backup and recovery capabilities.[444]                                          In addition, the DLSA includes commitments from MEMX Technologies as developer, licensor, and operator of the Technology and System to cooperate with the Exchange and provide the Exchange with the information and access that the Exchange reasonably believes will allow the Exchange to satisfy its obligations under Regulation SCI.[445] 

                    One commenter stated that it does “not see how 24X would be able to comply with Regulation SCI when it would not be in control of its own systems. . . . The introduction of another essential business partner creates previously unprecedented conflicts of interest for a registered exchange and complications for ownership and governance.” [446]                                          Contrary to the commenter's statements, Regulation SCI contemplates the possibility of an SCI entity's SCI systems and indirect SCI systems being operated on its behalf by another entity.[447]                                          In fact, because SCI entities engage in outsourcing to varying degrees, the Commission stated when it adopted Regulation SCI, “if an SCI entity determines to utilize a third party for an applicable system, it is responsible for having in place processes and requirements to ensure that it is able to satisfy the requirements of Regulation SCI for systems operated on behalf of the SCI entity by a third party.” [448] 

                    Another commenter questioned how exchanges that are operating Regulation SCI systems “in production mode at all hours” would be able to comply with Regulation SCI, including requirements for systems testing.[449]                                          In its response, 24X set forth a description of how its policies and procedures comply with the requirements of Regulation SCI.[450]                                          The periodic capacity stress testing, testing of system changes and testing in conjunction with the annual SCI review will be coordinated by 24X technology operations with MEMX Technologies personnel, and that vulnerability and threat testing will be coordinated by 24X with an outside vendor who will perform the tests, and with MEMX Technologies personnel as necessary.[451]                                          Finally, as discussed above, in Amendment No. 2, 24X has modified the 24X Market System so that trading will not occur on weekends. Accordingly, the concerns raised about systems testing when Regulation SCI systems would be “in production mode at all hours” are no longer germane. Based on the statements 24X has made in the Form 1, as amended, and 24X's response to commenters with respect to its obligations under Regulation SCI, as well as the provisions in the DLSA as described by 24X in the Form 1, 24X's proposal regarding the engagement of a third party to develop, license, and operate the Technology and System is designed to support the Exchange's ability to comply with its regulatory obligations under Regulation SCI.                

###                     F.                     *Discipline and Oversight of Members*

                    As stated above, one prerequisite for the Commission's grant of an exchange's application for registration is that a proposed exchange must be so organized and have the capacity to be able to carry out the purposes of the Exchange Act.[452]                                          Specifically, an exchange must be able to enforce compliance by its members and persons associated with its members with the federal securities laws and rules thereunder and the rules of the exchange.[453]                                          Pursuant to an RSA with FINRA, FINRA will perform many of the initial disciplinary processes on behalf of 24X.[454]                                          For example, FINRA will investigate potential securities laws violations, issue complaints, and conduct hearings pursuant to 24X rules. Appeals from disciplinary decisions will be heard by the 24X Appeals Committee,[455]                                          and the 24X Appeals Committee's decision shall be final.[456]                                          In addition, the 24X Board on its own initiative may order review of a disciplinary decision.[457] 

                    The 24X LLC Agreement and 24X rules provide that the Exchange has disciplinary jurisdiction over its Members [458]                                          so that it can enforce its Members' compliance with its rules and the federal securities laws and rules.[459]                                          The Exchange's rules also permit 24X to sanction Members for violations of its rules and violations of the federal securities laws and rules by, among other things, expelling or suspending Members, limiting Members' activities, functions, or operations, fining or censuring Members, or suspending or barring a person from being associated                           ( print page 97117)                        with a Member, or any other fitting sanction.[460]                                          24X's rules also provide for the imposition of fines for certain minor rule violations in lieu of commencing disciplinary proceedings.[461]                                          Accordingly, as a condition to the operation of 24X, a Minor Rule Violation Plan (“MRVP”) filed by 24X under Exchange Act Rule 19d-1(c)(2) must be declared effective by the Commission.[462] 

                    The Commission finds that the 24X LLC Agreement and 24X rules concerning its disciplinary and oversight programs are consistent with the requirements of sections 6(b)(6) and 6(b)(7) of the Exchange Act [463]                                          in that they provide fair procedures for the disciplining of members and persons associated with members. The Commission further finds that the rules of 24X provide it with the ability to comply, and with the ability to enforce compliance by its Members and persons associated with its Members, with the provisions of the Exchange Act, the rules and regulations thereunder, and the rules of 24X.[464] 

###                     G.                     *Trading on 24X Pursuant to Unlisted Trading Privileges*

                    24X does not intend to be a primary listing market for securities.[465]                                          Accordingly, 24X has not proposed rules that would allow it to primarily list any securities at this time. Instead, 24X has proposed to trade securities pursuant to UTP. 24X Rule 14.1 establishes the Exchange's authority to trade securities on a UTP basis. 24X Rule 14.1(a) provides that 24X may extend UTP to any security that is an NMS stock that is listed on another national securities exchange or with respect to which UTP may otherwise be extended in accordance with section 12(f) of the Exchange Act.[466]                                          24X Rule 14.1(a) further provides that any such security would be subject to all 24X rules applicable to trading on 24X, unless otherwise noted.                

                    24X Rule 14.1(b) establishes additional rules for trading of UTP Exchange Traded Products, which are defined in 24X Rule 1.5(nn).[467]                                          24X Rule 14.1(b) provides that 24X will distribute an information circular prior to the commencement of trading in a UTP Exchange Traded Product that generally would include the same information as the information circular provided by the listing exchange, including (a) the special risks of trading the Exchange Traded Product, (b) the Exchange's rules that would apply to the Exchange Traded Product, and (c) information about the dissemination of value of the underlying assets or indices. 24X Rule 14.1(b)(2) establishes certain requirements for Members that have customers that trade UTP Exchange Traded Products.[468]                                          24X Rule 14.1(b)(4) also establishes certain requirements for any Member registered as a Market Maker in a UTP Exchange Traded Product that derives its value from one or more currencies, commodities, or derivatives based on one or more currencies or commodities, or is based on a basket or index composed of currencies or commodities. 24X Rule 14.1(b)(5) provides that the Exchange's surveillance procedures for Exchange Traded Products traded on the Exchange pursuant to UTP would be similar to the procedures used for equity securities traded on the Exchange and would incorporate and rely upon existing Exchange surveillance systems.                

                    The Commission finds that the Exchange's proposed approach to the trading of securities on a UTP basis, as set forth in 24X Rule 14.1, is consistent with section 12(f) of the Exchange Act and Rule 12f-5 thereunder.[469]                                          Rule 12f-5 under the Exchange Act requires an exchange that extends unlisted trading privileges to securities to have in effect a rule or rules providing for transactions in the class or type of security to which the exchange extends unlisted trading privileges.[470]                                          24X Rule 14.1 includes a provision that any security traded UTP on the Exchange “shall be subject to all Exchange rules applicable to trading on the Exchange, unless otherwise noted.” [471]                                          The provisions in 24X Rule 14.1 are substantively the same as the existing rules of the MEMX Exchange.[472]                                          Accordingly, pursuant to section 12(f) of the Exchange Act and Rule 12f-5 thereunder, 24X will be permitted to extend unlisted trading privileges to securities of the same class, subject to the trading rules of the Exchange.                

###                     H.                     *Section 11(a) of the Exchange Act*

                    Section 11(a)(1) of the Exchange Act [473]                                          prohibits a member of a national securities exchange from effecting transactions on that exchange for its own account, the account of an associated person, or an account over which it or its associated person exercises investment discretion (collectively, “covered accounts”) unless an exception applies. Rule 11a2-2(T) under the Exchange Act,[474]                                          known as the “effect versus execute” rule, provides exchange members with an exemption from the section 11(a)(1) prohibition. Rule 11a2-2(T) permits an exchange member, subject to certain conditions, to effect transactions for covered accounts by arranging for an unaffiliated member to execute transactions on the exchange. To comply with Rule 11a2-2(T)'s conditions, a member: (i) must transmit the order from off the exchange floor; (ii) may not participate in the execution of the transaction once it has been transmitted to the member performing the execution; [475]                                          (iii) may not be affiliated with the executing member; and (iv) with respect to an account over which the member or an associated person has investment discretion, neither the member nor its associated person may retain any compensation in connection with effecting the transaction except as provided in the Rule.                

                    In a letter to the Commission, 24X requested that the Commission concur with 24X's conclusion that 24X                           ( print page 97118)                        Members that enter orders into the 24X trading system satisfy the conditions of Rule 11a2-2(T).[476]                                          For the reasons set forth below, 24X Members entering orders into the 24X trading system could satisfy the requirements of Rule 11a2-2(T).                

                    Rule 11a2-2(T)'s first condition is that orders for covered accounts be transmitted from off the exchange floor. In the context of automated trading systems, the Commission has found that the off-floor transmission condition is met if a covered account order is transmitted from a remote location directly to an exchange's floor by electronic means.[477]                                          24X represents that 24X does not have a physical trading floor, and the 24X trading system will receive orders from members electronically through remote terminals or computer-to-computer interfaces.[478]                                          The 24X trading system satisfies this off-floor transmission condition.                

                    The second condition requires that the member and any associated person not participate in the execution of its order after the order has been transmitted. 24X represents that at no time following the submission of an order is a member or an associated person of the member able to acquire control or influence over the result or timing of the order's execution.[479]                                          According to 24X, the execution of a member's order is determined solely by what quotes and orders are present in the system at the time the member submits the order, and the order priority based on the 24X rules.[480]                                          Accordingly, a 24X member and its associated persons do not participate in the execution of an order submitted to the 24X trading system.[481] 

                    The third condition states that the order be executed by an exchange member who is unaffiliated with the member initiating the order. The Commission has stated that this condition is satisfied when automated exchange facilities, such as the 24X trading system, are used, as long as the design of these systems ensures that members do not possess any special or unique trading advantages in handling their orders after transmitting them to the exchange.[482]                                          24X represents that the design of the 24X trading system ensures that no member has any special or unique trading advantage in the handling of its orders after transmitting its orders to 24X.[483]                                          Based on 24X's representation, the 24X trading system satisfies this condition.                

                    Fourth, in the case of a transaction effected for an account with respect to which the initiating member or an associated person thereof exercises investment discretion, neither the initiating member nor any associated person thereof may retain any compensation in connection with effecting the transaction, unless the person authorized to transact business for the account has expressly provided otherwise by written contract that refers to section 11(a) of the Exchange Act and Rule 11a2-2(T) thereunder.[484]                                          24X members trading for covered accounts over which they exercise investment discretion must comply with this condition in order to rely on the rule's exemption.[485] 

## IV. Exemption from Section 19(b) of the Exchange Act With Regard to FINRA Rules Incorporated by Reference

                    24X proposes to incorporate by reference certain FINRA rules as 24X rules.[486]                                          Thus, for those 24X rules, Exchange Members will comply with the 24X rule by complying with the FINRA rule referenced therein. In connection with its proposal to incorporate FINRA rules by reference, 24X requests, pursuant to Rule 240.0-12,[487]                                          an exemption under Section 36 of the Exchange Act from the rule filing requirements of section 19(b) of the Exchange Act for changes to those 24X rules that are effected solely by virtue of a change to a cross-referenced FINRA rule.[488]                                          24X represents in its letter that, as a condition to the exemption, it will provide written notice to its Members whenever a proposed rule change to a FINRA rule that is incorporated by reference is proposed and whenever any such proposed change is approved by the Commission or otherwise becomes effective.[489] 
      ( print page 97119)    
                    Using its authority under section 36 of the Exchange Act,[490]                                          the Commission is hereby granting 24X's request for an exemption, pursuant to section 36 of the Exchange Act, from the rule filing requirements of section 19(b) of the Exchange Act with respect to the rules that 24X proposes to incorporate by reference.[491]                                          This exemption is conditioned upon 24X providing written notice to its Members whenever FINRA proposes to change a rule that 24X has incorporated by reference. This exemption is appropriate, in the public interest and consistent with the protection of investors because it will promote more efficient use of Commission and SRO resources by avoiding duplicative rule filings based on simultaneous changes to identical rules of more than one SRO.                

## V. Conclusion

*It is ordered*                     that the application of 24X for registration as a national securities exchange be, and it hereby is, granted.                

*It is furthered ordered*                     that operation of 24X is conditioned on the satisfaction of the requirements below:

From and after the redemption date (unless 24X Bermuda defaults in providing funds for the payment of the redemption price), the redeemed Units or Unit Equivalents that have been redeemed will become treasury shares, and all rights of the holder of the redeemed Units or Unit Equivalents in 24X Bermuda (except the right to receive from 24X Bermuda the redemption price against delivery to 24X Bermuda of evidence of ownership of the shares) will cease.                         *See id.*                         In addition, in the event that any redemption has resulted in any person owning such number of Units or Unit Equivalents that is in violation of the ownership limits, 24X Bermuda will be required to redeem those Units or Unit Equivalents pursuant to the limitation provisions.                         *See id.*

243.

Moreover, the commenters state that the cost of a closure, that a traders' positions may deviate far from their desired positions, is, according to the commenter, outweighed by its benefits.                         *See*                         Blonien and Ober Letter at 1.

This commenter also stated that the Commission must consider how the 24X Form 1 would interact with “outstanding equity market structure proposals.”                         *See*                         SIFMA Letter at 6-7.

After submission of the comment letter, the Commission adopted amendments to Regulation NMS on Sept. 18, 2024.                         *See*                         Securities Exchange Act Release No. 101070 (Sept. 18, 2024), 89 FR 81620 (Oct. 8, 2024) (“2024 Regulation NMS Adopting Release”). The commenter also asked questions about proposed Regulation Best Execution, Securities Exchange Act Release No. 96496 (Dec. 14, 2022), 88 FR 5540 (Jan. 27, 2023); and the proposed Order Competition Rule, Securities Exchange Act Release No. 96495 (Dec. 14, 2022), 88 FR 128 (Jan. 3, 2023). 24X stated that “addressing how such proposals may relate to 24X's exchange application are outside of the scope of consideration of whether 24X's exchange application complies with the requirements of the Exchange Act.”                         *See*                         24X Letter II at 19. Proposed Regulation Best Execution and the proposed Order Competition Rule remain proposals. The commenter submitted a second letter requesting confirmation about the application of aspects of the 2024 Regulation NMS Adopting Release during the 24X Market Session.                         *See*                         SIFMA Letter II at 13. The questions posed by the commenter are addressed within the 2024 Regulation NMS Adopting Release and existing rules and regulations. The 2024 Regulation NMS Adopting Release, as well as the definitions included in Rule 600 of Regulation NMS and the specific rules under Regulation NMS, define the application of the rules during different trading sessions.

For example, the commenter stated that certain aspects of Regulation NMS only apply during Regular Trading Hours, such as Rule 611 of Regulation NMS, and that certain definitions in Rule 600 of Regulation NMS specify Regular Trading Hours, such as “covered order.”                         *See*                         SIFMA Letter I at 4.

As a matter of course, the Commission will consider any future amendments to the Equity Data Plans and any proposed rule changes filed by 24X upon filing, pursuant to the applicable statutory provisions and rules.

Under Rule 11.15(a)(1) as initially proposed, this figure (rounded to the nearest $0.01) would then be added to the Reference Price to calculate the “Upper 24X Price Band” and subtracted from the Reference Price to calculate the “Lower 24X Price Band” and no trades would be allowed outside the 24X Price Bands.

As discussed above, 24X will not be a listing market.                         *See*                         24X Rule 14.1.

In response, 24X stated, and the Commission agrees, that “the determination of how and when pricing decisions for mutual funds would be made by the mutual funds in accordance with relevant legal requirements, not by 24X.” 24X Letter II at 19. 24X further stated, and the Commission agrees, that the “24X Market Session does not present new issues regarding the timing of the pricing of mutual funds” because “trading already takes place on exchange today during pre-market sessions and post-market sessions (including overnight in the OTC market)” and “mutual funds have already faced such timing decisions.”                         *Id.*

Specifically, the commenter stated that for certain transactions on Fridays, Saturdays, Sundays, and holidays, the day after the trade might not be a business day and thus the settlement periods would be longer than T+1. As noted above, in Amendment No. 2, 24X amended the 24X rules for the 24X Market Session so that 24X will not offer trading on weekends and holidays. The commenter submitted a second comment that raised questions about clearance and settlement of trades in the amended 24X Market Session, as well as the 24X Market Session as originally proposed.                         *See*                         SIFMA Letter II.

The commenter further questioned whether the NSCC (1) would require an additional deposit to support overnight activity; (2) would process trades that occur on Saturday on the following Monday or Tuesday; (3) require Monday morning stock loan delivery or margin calls for weekend trades. The commenter also questioned whether clearing firms would be able to opt-out of clearing extended hours (pre-, post-, and overnight) activity.                         *Id.*                         These interpretative questions about NSCC rules should be directed to the NSCC, an SRO. As discussed throughout, trading of NMS stocks occurs overnight in the OTC market on ATSs. The commenter did not detail how the 24X proposal, as amended, raises new or novel concerns as compared to existing overnight trading sessions.

This commenter posed a number of questions that were interpretive in nature or technical and related to implementation of extended hours trading. As discussed throughout, there are existing extended hours trading sessions on other exchanges and the rules that are applicable during extended hours sessions are clear. The commenter stated that a broader consideration of extended hours trading in the national market system should be conducted.                         *See supra*                         section III.D.2.a (discussing comments requesting a roundtable or broader consideration of extended hours trading).

However, the Commission believes that these methods may not be sufficient in all cases to ensure that the requirements of Regulation SCI are met for SCI systems operated by third parties. . . . . Instead, if an SCI entity determines to utilize a third party for an applicable system, it is responsible for having in place processes and requirements to ensure that it is able to satisfy the requirements of Regulation SCI for systems operated on behalf of the SCI entity by a third party. The Commission believes that it would be appropriate for an SCI entity to evaluate the challenges associated with oversight of third-party vendors that provide or support its applicable systems subject to Regulation SCI. If an SCI entity is uncertain of its ability to manage a third-party relationship (whether through due diligence, contract terms, monitoring, or other methods) to satisfy the requirements of Regulation SCI, then it would need to reassess its decision to outsource the applicable system to such third party.”).

In considering the operation of automated execution systems operated by an exchange, the Commission stated that, while there is not an independent executing exchange member, the execution of an order is automatic once it has been transmitted into the system. Because the design of these systems ensures that members do not possess any special or unique trading advantages in handling their orders after transmitting them to the exchange, the Commission has stated that executions obtained through these systems satisfy the independent execution condition of Rule 11a2-2(T).                         *See*                         1979 Release,                         *supra*                         note 477.
