I. Introduction

On February 23, 2018, Nasdaq ISE, LLC (“ISE” or “Exchange”) 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 Exchange Rule 714 regarding the Acceptable Trade Range (“ATR”) functionality for orders that are routed to away markets. The proposed rule change was published for comment in the Federal Register on March 14, 2018.^[3] On April 20, 2018, the Exchange submitted Amendment No. 1 to the proposed rule change, which replaced and superseded the original filing in its entirety.^[4] On April 26, 2018, the Commission extended the time period within which to approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether to disapprove the proposed rule change to June 22, 2018.^[5] The Commission received no comments on the proposed rule change. The Commission is publishing this notice to solicit comment on Amendment No. 1 to the proposed rule change from interested persons and is approving the proposed rule change, as modified by Amendment No. 1, on an accelerated basis.

II. Description of the Proposed Rule Change, as Modified by Amendment No. 1 ^[6]

The ATR is a functionality designed to prevent the Exchange's System ^[7] from experiencing dramatic price swings by preventing the execution of orders beyond set thresholds.^[8] Pursuant to Exchange Rule 714(b)(1), the System calculates an ATR to limit the range of prices at which an order or quote will be allowed to execute.^[9] Upon receipt of a new order or quote, the ATR is calculated by taking the reference price, plus or minus a value to be determined by the Exchange, where the reference price is the NBB for sell orders/quotes and the NBO for buy orders/quotes.^[10] Accordingly, the ATR is: The reference price−(x) for sell orders/quotes; and the reference price + (x) for buy orders.^[11] If an order or quote reaches the outer limit of the ATR without being fully executed, then any unexecuted balance will be cancelled.^[12]

The Exchange states that, currently, the System calculates a reference price for an incoming order or quote only when that order or quote rests or trades on the regular order book.^[13] Accordingly, orders that route to away exchanges do not always receive the ATR. Orders that first trade on the Exchange prior to being routed away receive the ATR, but orders that are routed away upon entry (or otherwise do not rest or trade on the regular order book) are not currently subject to the ATR.^[14]

The Exchange now proposes to amend the ATR to modify how it applies to orders that are routed by the Exchange. First, the Exchange proposes to apply the ATR to orders that are routed to away markets without first trading on the Exchange.^[15] This means that, unlike today, the System will calculate an ATR for orders even if the order does not rest or trade on the regular order book prior to being routed.^[16]

In addition, the Exchange proposes that, for orders routed to away markets pursuant to the Supplementary Material to Exchange Rule 1901,^[17] if the applicable NBB or NBO price is improved at the time the order is routed, a new ATR would be calculated based on the reference price at that time.^[18] The Exchange notes that the NBB or NBO price for a security may change during the “Flash” auction process described in Supplementary Material .02 to Rule 1901, and the proposed rule change would provide additional protection if the reference price was improved at the time the order is routed.^[19] Similarly, the Exchange represents that other routable orders not subject to the “Flash” auction process must still be processed by the System prior to routing, and during this processing time the market may have moved.^[20] Under the proposed rule change, if the NBB or NBO price has not improved at the time an order is routed, the ATR that was applied to the order upon entry into the System would apply.^[21]

The Exchange states that it intends to implement the ATR functionality described in the proposed rule change no later than October 31, 2018.^[22]

III. Discussion and Commission Findings

After careful review, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.^[23] In particular, the Commission finds that the proposed rule change, as modified by Amendment No. 1, is consistent with Section 6(b)(5) of the Act,^[24] which requires, among other things, that the rules of a national securities exchange be designed to prevent fraudulent and manipulative acts and practices, to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in facilitating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system, and, in general, to protect investors and the public interest.

The Commission believes that the ATR is reasonably designed to prevent executions of orders and quotes at prices that are significantly worse than the NBBO at the time of an order's submission and may reduce the potential negative impacts of unanticipated volatility in individual options.^[25] The Commission notes that the proposed rule change extends the application of the ATR to orders that route away immediately upon entry, thus offering these orders the same protections that the ATR provides to orders that first trade on the Exchange before being routed. The Commission also believes that recalculating the ATR for orders routed to away markets pursuant to the Supplementary Material to Rule 1901, if the applicable NBB or NBO price is improved at the time the order is routed, should help provide such orders with a price protection that better reflects the NBB or NBO. The Commission further believes that the proposed rule change will provide transparency and enhance investors' understanding of the operation of the ATR. The Commission notes that the Exchange will continue to use the NBB or NBO as the reference price for the ATR. For these reasons, the Commission believes that the proposed rule change, as modified by Amendment No. 1, is consistent with the Act.

III. Solicitation of Comments on Amendment No. 1

Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether Amendment No. 1 to the proposed rule change is consistent with the Exchange Act. Comments may be submitted by any of the following methods:

V. Accelerated Approval of Proposed Rule Change, as Modified by Amendment No. 1

The Commission finds good cause to approve the proposed rule change, as modified by Amendment No. 1, prior to the 30th day after the date of publication of notice of Amendment No. 1 in the Federal Register . As discussed above, Amendment No. 1 adds detail to the proposal and the proposed rule text regarding the operation of the ATR. Amendment No. 1 revises the proposed rule text to specify that for orders routed to away markets pursuant to the Supplementary Material to Rule 1901, if the applicable NBB or NBO price is improved at the time the order is routed, a new ATR will be calculated based on the reference price at that time. Amendment No. 1 also sets forth additional justification for the proposed rule change. The Commission believes that these revisions provide greater clarity with respect to the current and proposed application of the ATR for routed away orders. Accordingly, the Commission finds good cause, pursuant to Section 19(b)(2) of the Exchange Act,^[26] to approve the proposed rule change, as modified by Amendment No. 1 on an accelerated basis.

VI. Conclusion

It is therefore ordered, pursuant to Section 19(b)(2) of the Exchange Act,^[27] that the proposed rule change (SR-ISE-2018-16), as modified by Amendment No. 1 thereto, be, and it hereby is, approved on an accelerated basis.
