###### Securities and Exchange Commission

          - [Release No. 34-82498; File No. SR-NYSEAMER-2017-26]

## I. Introduction

                    On November 17, 2017, NYSE American LLC (“Exchange” or “NYSE American”) filed with the Securities and Exchange Commission (“Commission”) pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) [1]                                          and Rule 19b-4 thereunder,[2]                                          a proposed rule change to amend Rule 971.1NY (Electronic Cross Transactions) to modify the parameters for the duration of a Customer Best Execution (“CUBE”) Auction. The proposed rule change was published for comment in the                     **Federal Register**                     on December 4, 2017.[3]                                          The Commission received no comment letters on the proposed rule change. This order approves the proposed rule change.                

## II. Description of the Proposed Rule Change

                    CUBE is a process by which an ATP Holder may electronically submit for execution an order it represents as agent (“CUBE Order”) against principal interest or against any other order it represents as agent.[4]                                          When the Exchange receives a valid CUBE Order for auction processing, a Request for Responses (“RFR”) detailing the series, the side of the market, the size of the CUBE Order, and the limit price of the CUBE Order is sent to all ATP Holders that subscribe to receive RFR messages. Currently, the amount of time given to ATP Holders to respond with competing interest to trade against the CUBE Order (“Response Time Interval”) is randomly set by the CUBE mechanism for each auction but cannot be shorter than 500 milliseconds or longer than 750 milliseconds, unless the auction is concluded early.[5]                                          The Exchange proposes to revise the Response Time Interval to provide that the duration of a CUBE Auction shall be a random period of time within parameters                           ( print page 2824)                        designated by the Exchange, which parameters shall be no less than 100 milliseconds and no more than one second.[6]                                          The proposal would require the Exchange to announce in advance, by Trader Update, any changes to the parameters.[7] 

                    The Exchange states that the proposed rule change, among other things, would provide investors with more timely execution of their option orders while ensuring that there is an adequate exposure of orders in the CUBE mechanism; could provide more CUBE Orders an opportunity for price improvement by reducing market risk for ATP Holders that participate in CUBE Auctions; would give the Exchange flexibility in establishing the optimal duration of CUBE Auctions; and would encourage competition and thereby enhance the potential for price improvement.[8] 

                    To substantiate that its members can receive, process, and communicate a response back to the Exchange within 100 milliseconds (the shortest possible duration of the Response Time Interval), the Exchange states that it surveyed all ATP Holders that responded to a CUBE Auction broadcast in the three months prior to the filing of this proposed rule change.[9]                                          According to the Exchange, each ATP Holder it surveyed indicated that it can receive, process, and communicate a response back to the Exchange within 100 milliseconds.[10]                                          The Exchange further states that it has analyzed its capacity and represents that it has the necessary systems capacity to handle the potential additional traffic associated with the additional transactions that may occur with the implementation of the proposed reduction of the Response Time Interval to no less than 100 milliseconds.[11]                                          The Exchange further represents that its system will be able to sufficiently maintain an audit trail for order and trade information with the reduction in the Response Time Interval.[12] 

## III. Discussion and Commission's Findings

                    After careful review, the Commission finds that the proposed rule change is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.[13]                                          In particular, the Commission finds that the proposed rule change is consistent with Section 6(b)(5) of the Act,[14]                                          which requires, among other things, that the rules of a national securities exchange be designed to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system and, in general, to protect investors and the public interest, and not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers. The Commission also finds that the proposed rule change is consistent with Section 6(b)(8) of the Act,[15]                                          which requires that the rules of an exchange not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.                

                    The Commission believes that, as NYSE American maintains, permitting the Exchange to designate an exposure time period of as short as100 milliseconds in the CUBE Auction is consistent with the Commission's past approval of rules of options exchanges that govern the duration of their electronic auctions. These rules provide for a period of as short as 100 milliseconds for market participants to submit responses to an auction announcement before the auction ends.[16]                                          Similarly, the Commission has approved rules allowing options exchanges to set an exposure period of up to one second.[17] 

                    The Commission notes that the fact that, in CUBE, a Response Time Interval is separately and randomly set by the auction mechanism for each individual auction (provided that no auction can be longer or shorter than specified limits) is not unique with respect to the instant proposal.[18]                                          The feature of CUBE that randomly sets a Response Time Interval for each auction—which is unique in contrast to electronic auction mechanisms at other options exchanges—has been a component of CUBE since approval of the Exchange's Rule governing the CUBE [19]                                          and is consistent with the mechanism's current functionality.                

The Exchange's proposal revises how the minimum and maximum time lengths for the randomly-set Response Time Interval for each CUBE Auction would be established. Currently, Exchange Rule 971.1NY sets the minimum and maximum: no less than 500 milliseconds and no more than 750 milliseconds. Under the proposal, the Exchange is granted the discretion to establish the minimum and maximum possible durations of an auction and change them from time to time (with adequate notice to market participants). However, that discretion itself is restricted under the proposal. The Exchange would not be permitted to establish the limits in a way that would allow even a randomly-set Response Time Interval to be shorter than 100 milliseconds or longer than one second. The Commission thus notes that, under the proposed parameters, the exposure period for an order submitted to a CUBE Auction could never be shorter than the exposure period of any other options exchange's electronic auction.

Accordingly, for the reasons discussed above, the Commission believes that the Exchange's proposal is consistent with the Act.

## IV. Conclusion

*It is therefore ordered,*                     pursuant to Section 19(b)(2) of the Act,[20]                                          that the                           ( print page 2825)                        proposed rule change (SR-NYSEAMER-2017-26) be, and hereby is, approved.                                    

                        For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.21
