###### Securities and Exchange Commission

          - [Release No. 34-92135; File No. SR-MIAX-2021-23]

Pursuant Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”),[1]            and Rule 19b-4 thereunder,[2]            notice is hereby given that on May 28, 2021, Miami International Securities Exchange LLC (“MIAX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) a proposed rule change as described in Items I, II, and III below, which Items have been prepared by the Exchange. The Commission is publishing this notice to solicit comments on the proposed rule change from interested persons.

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

The Exchange is filing a proposal to amend the MIAX Options Fee Schedule (the “Fee Schedule”) to adopt fees for a new data product to be known as the Open-Close Report.

The text of the proposed rule change is available on the Exchange's website at *http://www.miaxoptions.com/​rule-filings,* at MIAX's principal office, and at the Commission's Public Reference Room.

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

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

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

#### 1. Purpose

The Exchange recently adopted a new data product known as the Open-Close Report, which will be available for purchase to Exchange Members [3]            and non-Members.[4]            The Exchange now proposes to adopt fees for the Open-Close Report. The Open-Close Report is described under Exchange Rule 531(b)(1).

By way of background, the Exchange will offer two versions of the Open-Close Report, an end of day summary and intra-day report. The end-of-day version is a volume summary of trading activity on the Exchange at the option level by origin (Priority Customer, Non-Priority Customer, Firm, Broker-Dealer, and Market Maker [5]           ), side of the market (buy or sell), contract volume, and transaction type (opening or closing). The customer and professional customer volume is further broken down into trade size buckets (less than 100 contracts, 100-199 contracts, greater than 199 contracts). The Open-Close Data is proprietary Exchange trade data and does not include trade data from any other exchange. It is also a historical data product and not a real-time data feed.

The intraday Open-Close Report will provide similar information to that of Open-Close Data but will be produced and updated every 10 minutes during the trading day. Data is captured in “snapshots” taken every 10 minutes throughout the trading day and is available to subscribers within five minutes of the conclusion of each 10-minute period. For example, subscribers to the intraday product will receive the first calculation of intraday data by no later than 9:45 a.m. ET, which represents data captured from 9:30 a.m. to 9:40 a.m. Subscribers will receive the next update by 9:55 a.m., representing the data previously provided together with data captured from 9:40 a.m. through 9:50 a.m., and so forth. Each update will represent the aggregate data captured from the current “snapshot” and all previous “snapshots.” The intraday Open-Close Data will provide a volume summary of trading activity on the Exchange at the option level by origin (Priority Customer, Non-Priority Customer, Firm, Broker-Dealer, and Market Maker), side of the market (buy or sell), and transaction type (opening or closing). All volume will be further broken down into trade size buckets (less than 100 contracts, 100-199 contracts, greater than 199 contracts).

The Exchange anticipates a wide variety of market participants to purchase the Open-Close Report, including, but not limited to, individual customers, buy-side investors, and investment banks. The Exchange believes the Open-Close Report product may also provide helpful trading information regarding investor sentiment that may allow market       ( print page 31752)    participants to make better trading decisions throughout the day and may be used to create and test trading models and analytical strategies and provides comprehensive insight into trading on the Exchange. For example, intraday open data may allow a market participant to identify new interest or possible risks throughout the trading day, while intraday closing data may allow a market participant to identify fading interests in a security. The product is a completely voluntary product, in that the Exchange is not required by any rule or regulation to make this data available and that potential subscribers may purchase it only if they voluntarily choose to do so. The Exchange notes that other exchanges offer a similar data product.[6] 

The Exchange proposes to provide in its Fee Schedule that Members and non-Members may purchase the Open-Close Report on a monthly basis. The Exchange proposes to assess a monthly fee of $600 per month for subscribing to the end-of-day summary Open-Close Report and $2,000 per month for subscribing to the intra-day Open-Close Report. The Exchange also proposes to specify that for mid-month subscriptions, new subscribers will be charged for the full calendar month for which they subscribe and will be provided Open-Close Report data for each trading day of the calendar month from the day on which they subscribed. The proposed monthly fees will apply both to Members or non-Members. The Exchange notes that other exchanges provide similar data products that may be purchased on a monthly basis and are similarly priced.[7] 

The Exchange intends to begin to offer the Open-Close Report and charge the proposed fees on June 1, 2021.

#### 2. Statutory Basis

The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Act,[8]            in general, and furthers the objectives of Section 6(b)(5) of the Act,[9]            in particular, in that it is designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and to protect investors and the public interest, and that it is not designed to permit unfair discrimination among customers, brokers, or dealers. The Exchange also believes that its proposal to adopt fees for the Open-Close Report is consistent with Section 6(b) of the Act [10]            in general, and furthers the objectives of Section 6(b)(4) of the Act [11]            in particular, in that it is an equitable allocation of dues, fees and other charges among its members and other recipients of Exchange data.

In adopting Regulation NMS, the Commission granted self-regulatory organizations (“SROs”) and broker-dealers increased authority and flexibility to offer new and unique market data to the public. It was believed that this authority would expand the amount of data available to consumers, and also spur innovation and competition for the provision of market data. Particularly, the Open-Close Report further broadens the availability of U.S. option market data to investors consistent with the principles of Regulation NMS. The data product also promotes increased transparency through the dissemination of the Open-Close Report. Particularly, information regarding opening and closing activity across different option series during the trading day may indicate investor sentiment, which may allow market participants to make better informed trading decisions throughout the day. Subscribers to the data may also be able to enhance their ability to analyze option trade and volume data and create and test trading models and analytical strategies. The Exchange believes the Open-Close Report provides a valuable tool that subscribers can use to gain comprehensive insight into the trading activity in a particular series, but also emphasizes such data is not necessary for trading. Moreover, other exchanges offer a similar data product.[12] 

The Exchange operates in a highly competitive environment. Indeed, there are currently 16 registered options exchanges that trade options. Based on publicly available information, no single options exchange has more than 15% of the market share and currently the Exchange represents only approximately 6.74% of the market share.[13]            The Commission has repeatedly expressed its preference for competition over regulatory intervention in determining prices, products, and services in the securities markets. Particularly, in Regulation NMS, the Commission highlighted the importance of market forces in determining prices and SRO revenues and, also, recognized that current regulation of the market system “has been remarkably successful in promoting market competition in its broader forms that are most important to investors and listed companies.” [14]            Making similar data products available to market participants fosters competition in the marketplace, and constrains the ability of exchanges to charge supra-competitive fees. In the event that a market participant views one exchange's data product as more or less attractive than the competition they can and do switch between similar products. The proposed fees are a result of the competitive environment, as the Exchange seeks to adopt fees to attract purchasers of the recently introduced Open-Close Data product.
      ( print page 31753)    
The Exchange believes the proposed fees are reasonable as the proposed fees are both modest and similar to, or even lower than, the fees assessed by other exchanges that provide similar data products.[15]            Indeed, proposing fees that are excessively higher than established fees for similar data products would simply serve to reduce demand for the Exchange's data product, which as noted, is entirely optional. Like the Exchange's Open-Close Report, other exchanges offer similar data products that each provide insight into trading on those markets and may likewise aid in assessing investor sentiment. Although each of these similar Open-Close data products provide only proprietary trade data and not trade data from other exchanges, it is possible investors are still able to gauge overall investor sentiment across different option series based on open and closing interest on any one exchange.[16]            Similarly, market participants may be able to analyze option trade and volume data, and create and test trading models and analytical strategies using only Open-Close data relating to trading activity on one or more of the other markets that provide similar data products. As such, if a market participant views another exchange's Open-Close data as more attractive than its proposed Open-Close Report, then such market participant can merely choose not to purchase the Exchange's Open-Close Report and instead purchase another exchange's Open-Close data product, which offer similar data points, albeit based on that other market's trading activity.

The Exchange also believes the proposed fees are reasonable as they would support the introduction of a new market data product that is designed to aid investors by providing insight into trading on the Exchange. The recently adopted Open-Close Report would provide options market participants with valuable information about opening and closing transactions executed on the Exchange throughout the trading day, similar to other trade data products offered by competing options exchanges. In turn, this data would assist market participants in gauging investor sentiment and trading activity, resulting in potentially better informed trading decisions. As noted above, users may also use such data to create and test trading models and analytical strategies.

Selling market data, such as the Open-Close Report, is also a means by which exchanges compete to attract business. To the extent that the Exchange is successful in attracting subscribers for the Open-Close Report, it may earn trading revenues and further enhance the value of its data products. If the market deems the proposed fees to be unfair or inequitable, firms can diminish or discontinue their use of the data and/or avail themselves of similar products offered by other exchanges.[17]            The Exchange therefore believes that the proposed fees for the Open-Close Report reflect the competitive environment and would be properly assessed on Member or non-Member users. The Exchange also believes the proposed fees are equitable and not unfairly discriminatory as the fees would apply equally to all users who choose to purchase such data. The Exchange's proposed fees would not differentiate between subscribers that purchase the Open-Close Report and are set at a modest level that would allow any interested Member or non-Member to purchase such data based on their business needs.

As noted above, the Exchange anticipates a wide variety of market participants to purchase the Open-Close Report, including but not limited to individual customers, buy-side investors and investment banks. The Exchange reiterates that the decision as to whether or not to purchase the Open-Close Report is entirely optional for all potential subscribers. Indeed, no market participant is required to purchase the Open-Close Report, and the Exchange is not required to make the Open-Close Report available to all investors. Rather, the Exchange is voluntarily making the Open-Close Report available, as requested by customers, and market participants may choose to receive (and pay for) this data based on their own business needs. Potential purchasers may request the data at any time if they believe it to be valuable or may decline to purchase such data.

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

The Exchange does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. Rather, the Exchange believes that the proposal will promote competition by permitting the Exchange to sell a data product similar to those offered by other competitor options exchanges.[18]            The Exchange made Open-Close Data available in order to keep pace with changes in the industry and evolving customer needs, and believes the data product will contribute to robust competition among national securities exchanges. At least eight other U.S. options exchanges offer a market data product that is substantially similar to the Open-Close Report. As a result, the Exchange believes this proposed rule change permits fair competition among national securities exchanges.

Furthermore, the Exchange operates in a highly competitive environment, and its ability to price the Open-Close Report is constrained by competition among exchanges that offer similar data products to their customers. As discussed, there are currently a number of similar products available to market participants and investors. At least eight other U.S. options exchanges offer a market data product that is substantially similar to the Open-Close Report, which the Exchange must consider in its pricing discipline in order to compete for the market data.[19]            For example, proposing fees that are excessively higher than established fees for similar data products would simply serve to reduce demand for the Exchange's data product, which as discussed, market participants are under no obligation to utilize. In this competitive environment, potential purchasers are free to choose which, if any, similar product to purchase to satisfy their need for market information. As a result, the Exchange believes this proposed rule change permits fair competition among national securities exchanges.

The Exchange also does not believe the proposed fees would cause any unnecessary or in appropriate burden on intermarket competition as other exchanges are free to introduce their own comparable data product and lower their prices to better compete with the Exchange's offering. The Exchange does not believe the proposed rule change would cause any unnecessary or inappropriate burden on intramarket competition. Particularly, the proposed product and fees apply uniformly to any purchaser, in that it does not differentiate between subscribers that purchase the Open-Close Report. The proposed fees are set at a modest level that would allow any interested Member or non-Member to purchase such data based on their business needs.      ( print page 31754)    

### 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 foregoing rule change has become effective pursuant to Section 19(b)(3)(A)(ii) of the Act,[20]            and Rule 19b-4(f)(2) [21]            thereunder. At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
