      ( print page 97126)    

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

                    Pursuant to the provisions of Section 19(b)(1) under the Act,[4]                                          and Rule 19b-4 thereunder,[5]                                          the Exchange is filing with the Commission a proposed rule change to provide that DEEP+ data will be included in its HIST [6]                                          Data Product. The Exchange has designated this rule change as “non-controversial” under Section 19(b)(3)(A) of the Act [7]                                          and provided the Commission with the notice required by Rule 19b-4(f)(6) thereunder.[8] 

                    The text of the proposed rule change is available at the Exchange's website at                     *www.iextrading.com,*                     at the principal office of the Exchange, and at the Commission's Public Reference Room.                

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

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

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

#### 1. Purpose

The Exchange is making this filing to provide that DEEP+ data will be included in its HIST Data Product.

                    IEX introduced HIST in 2017.[9]                                          HIST is “a data product that offers historical data.” [10]                                          At the time IEX introduced HIST, the Exchange offered two real-time data products: TOPS,[11]                                          an uncompressed data feed that offers aggregated top of book quotations for all displayed orders resting on the Order Book; and DEEP,[12]                                          an uncompressed data feed that provides aggregated depth of book quotations for all displayed orders resting on the Order Book at each price level.[13]                                          Thus, in the 2017 filing to adopt HIST, IEX described HIST as including “the same substantive data that is provided in real time via TOPS and DEEP on a T+1 basis via the Exchange's public website, free of charge.” [14] 

                    IEX recently filed an immediately effective rule change proposal to introduce a new data product, DEEP+, which will disseminate, on a real-time basis, order-by-order information for all displayed orders resting on the Order Book for securities traded on IEX and execution information (                    *i.e.,*                     last sale information) for executions on the Exchange.[15]                                          While DEEP+ and DEEP will both provide information about all displayed orders resting on the IEX Order Book (and last sale information), DEEP+ will provide information about each displayed resting order, while DEEP will continue to provide information about the total volume of displayed interest resting at any price.[16]                                          IEX plans to introduce DEEP+ on December 9, 2024.[17] 

                    While IEX Rule 11.330(a)(5), which describes HIST, is not specific as to which historical data is included therein, IEX's 2017 rule filing adopting HIST provided that TOPS and DEEP data would be included, as noted above. Accordingly, the Exchange is making this rule filing to provide that HIST will also include DEEP+ data. IEX is not proposing to modify the language in Rule 11.330(a)(5) which will continue to state: “HIST. Historical Data is a data product that offers historical data.” IEX notes that other exchanges that offer an historical data product do not provide specificity on which of their market data products are included in their historical data products.[18] 

####                     2. Statutory Basis                

                    The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act,[19]                                          in general, and furthers the objectives of Section 6(b)(5),[20]                                          in particular, in that it would remove impediments to and perfect the mechanism of a free and open market and a national market system because it is designed to add the same substantive data that IEX will provide in real-time via the new DEEP+ data product to HIST, thereby providing additional transparency regarding historical IEX displayed orders to Members [21]                                          and other users of IEX data products.                

                    As discussed in the Purpose section, IEX publishes the HIST file, which contains the same substantive data that is provided in real-time via TOPS and DEEP, to its website after the close of trading, where it is offered free of charge. Adding DEEP+ data to HIST is fully consistent with this approach. Further, other exchanges offer depth of book data in their historical data products in a comparable manner.[22]                                          Therefore, the Exchange does not believe that this proposed rule change raises any new or novel issues not already considered by the Commission.                

IEX also believes that the proposed rule change is nondiscriminatory since all Members and other market participants will be able to access DEEP+ data through HIST.

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

The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. As described in the Purpose and Statutory Basis sections, this rule filing merely proposes to add to its HIST data product the substantive data that will be provided in real-time via the new DEEP+ market data product, which will provide enhanced transparency to Members and other users of IEX data products regarding historical displayed orders on IEX.

With regard to intra-market competition, the proposed rule change will apply equally to all Members and other market participants on a fair, impartial and nondiscriminatory basis without imposing any new burdens. Access to HIST is optional and will be available to all Members and market participants in the same manner.

                    With regard to inter-market competition, other exchanges are free to adopt similar data products subject to                           ( print page 97127)                        the SEC rule filing process, and others have done so.[23] 

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

Written comments were neither solicited nor received.

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

                    The Exchange has designated this rule filing as non-controversial under Section 19(b)(3)(A) [24]                                          of the Act and Rule 19b-4(f)(6) [25]                                          thereunder. Because the proposed rule change does not (i) significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [26]                                          and Rule 19b-4(f)(6) thereunder.[27] 

                    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the Act [28]                                          normally does not become operative for 30 days after the date of its filing. However, Rule 19b-4(f)(6)(iii) [29]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that the proposal may be operative concurrent with IEX's planned implementation of DEEP+ on December 9, 2024. The Commission believes that the proposed rule change raises no novel issues and that waiver of the operative delay is consistent with the protection of investors and the public interest. Therefore, the Commission hereby waives the operative delay and designates the proposal operative upon filing.[30] 

                    At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings under Section 19(b)(2)(B) [31]                                          of the Act to determine whether the proposed rule change should be approved or disapproved.
