March 18, 2019.
On November 30, 2018, the Investors Exchange, LLC (“IEX” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
and Rule 19b-4 thereunder,
a proposed rule change to modify the resting price of Discretionary Peg orders. The proposed rule change was published for comment in the Federal Register on December 19, 2018.
The Commission received two comments on the proposed rule change,
and one response letter from the Exchange.
On March 13, 2018, the Exchange filed Amendment No. 1 to the proposed rule change.
The Commission is publishing this notice to solicit comments on Amendment No. 1 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
The Exchange offers a Discretionary Peg order type that is an entirely non-displayed, pegged order.
Upon entry, the order is priced by the IEX system to be equal to the less aggressive of the midpoint of the NBBO or the order's limit price, if any. Currently, any unexecuted portion of the order is posted and ranked non-displayed on the IEX order book at the near-side primary quote (i.e., the NBB for buy orders, the NBO for sell orders). Thereafter, the resting price of the order is automatically adjusted by the IEX system in response to changes in the NBB (NBO) for buy (sell) orders so that its non-displayed resting price remains pegged at the near-side primary quote, up (down) to the order's limit price, if any.
Once posted to the IEX order book, a Discretionary Peg order, in response to incoming active orders, will exercise the least amount of price discretion necessary from its resting price to its discretionary price, and thus may trade more aggressively up to (for buy orders) or down to (for sell orders) the midpoint of the NBBO,
but will only do so when the IEX system determines the quote in the subject security to be “stable.” 
When IEX determines the quote to be “unstable” for the subject security and activates the crumbling quote indicator (“CQI”) for up to 2 milliseconds, as specified in IEX Rule 11.190(g), Discretionary Peg orders do not exercise price discretion to trade at prices to the midpoint of the NBBO. However, Discretionary Peg orders remain eligible for execution at their resting price (i.e., at the NBB (NBO) for buy (sell) orders) when the CQI is on. Therefore, when IEX determines the quote to be unstable, Discretionary Peg orders are protected Start Printed Page 10872from trading more aggressively to a reference price that IEX determines may become stale imminently.
In its proposal, the Exchange now proposes to modify the resting price of Discretionary Peg orders to be equal to the less aggressive of 1 MPV less aggressive than the primary quote (rather than the primary quote itself) or the order's limit price. The Exchange notes that the proposed resting price for Discretionary Peg orders will be the same as the resting price of primary peg orders pursuant to IEX Rule 11.190(b)(8).
In its filing, the Exchange stated that one of the purposes for its proposed rule change was to “further protect resting Discretionary Peg orders from execution at a stale price” and noted that Discretionary Peg orders currently “remain susceptible to trading at the primary quote” when the CQI is on.
The Exchange further noted that, in its experience, while Discretionary Peg orders do not often execute at the primary quote, a considerable portion of such executions at the primary quote occur when the CQI is on.
Finally, the Exchange also proposes conforming changes to the description of the resting price of Discretionary Peg orders for purposes of ranking and priority in the Regular Market Session Opening Process for Non-IEX-Listed Securities and IEX Auctions.
III. Comment Letter and Exchange Response
The Commission received two comments from one commenter that opposed the proposal rule change.
The commenter expressed concern that IEX's proposal would allow a Discretionary Peg order to “jump over” other orders to price more aggressively up to the midpoint when the CQI signal indicates it is “safe” to do so, but IEX will “reprice” the order back below the near-side primary quote “to avoid execution” (emphasis in original) when the CQI signal indicates a potential unstable quote.
The commenter stated that, as a result of IEX's proposed rule change, “the Discretionary Peg [o]rder can avoid being executed at all whenever the CQI signal is active” 
and noted that current Discretionary Peg functionality to price more aggressively when the CQI is off “is partly counterbalanced by the fact that even when the CQI signal is active, Discretionary Peg [o]rders will still be executed.” 
The commenter argued that the proposal “would be eliminating this counterbalance” as a Discretionary Peg order would “never” execute when the CQI “predicted an imminent price change in the NBBO.” 
In turn, the commenter believed that the proposal presents a “conflict between the proposed change and the promotion of price discovery through the display of protected quotes.” 
In its second letter, the commenter noted that a Discretionary Peg order is “much more likely to be exercising discretion than not” as they are “eligible to trade more aggressively throughout the entire day with the exception of the 1.24 seconds when IEX has determined the market is unstable” (emphasis in original).
The commenter also noted that the merits of the proposal are subjective and “depend on the perspective from which the order is viewed.” 
For example, while IEX views the proposal as providing an additional measure of protection to Discretionary Peg orders when the CQI is on, “[f]rom the point of view of the seller, the [Discretionary Peg order] appears to have faded its interest in response to preferential access to market data.” 
The commenter further criticized the Exchange's lack of data or analysis on the impact that its proposal might have on the provision of displayed liquidity on IEX.
In its response, the Exchange stated its belief that the commenter described aspects of the Discretionary Peg order inaccurately.
In particular, the Exchange disagreed that Discretionary Peg orders “fall back” or reprice passively when the CQI is on, but rather characterized them as resting passively when the CQI is active.
Thus, the Exchange characterized the proposal as “rather than repricing when the CQI is active, IEX is simply proposing that [Discretionary Peg orders] rest more passively” than they do currently (emphasis in original).
The Exchange also argued that the commenter mischaracterized the operation of the Discretionary Peg order by suggesting it could “jump over” resting displayed orders.
The Exchange explained that a Discretionary Peg order “exercise[s] the least amount of price discretion necessary from [its] resting price to its discretionary price,” except during periods of quote instability, and “is prioritized behind any displayed or non-displayed interest resting at the discretionary price.” 
Thus, the Exchange explained that Discretionary Peg orders can only trade at prices more aggressive than resting displayed orders (i.e., at the midpoint) only when the active incoming order is priced less aggressive than the NBBO (i.e., active sell orders priced higher than the NBB or active buy orders priced lower than the NBO) (emphasis in original).
Further, the Exchange countered the commenter's assertion that, unlike displayed orders, Discretionary Peg orders would never be eligible to execute when the CQI is active. The Exchange explained that a Discretionary Peg order would remain eligible to trade at its proposed resting price when the active order is priced more aggressive than the NBBO.
Finally, the Exchange stated its belief that its proposed change did not present a novel application of discretionary pricing.
IV. Discussion and Commission Findings
After careful review of the proposal and the comments received thereon 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.
In particular, the Commission finds that the proposed rule change is consistent Start Printed Page 10873with Section 6(b)(5) of the Act,
which requires that the rules of an 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 regulating, clearing, settling, processing information with respect to, and 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 the proposed rule change is consistent with the protection of investors and the public interest because it is reasonably designed to protect non-displayed resting Discretionary Peg orders from unfavorable executions when IEX's precise rules-based mathematical quote instability formula suggests the possibility that the market may soon move against them in the next two milliseconds. If the market does move, the Discretionary Peg orders are re-ranked at a new resting price and permitted to once again exercise discretion to meet the limit price of active orders.
In general, the core design of a Discretionary Peg order, when resting, is to provide liquidity at a price as aggressive as the midpoint of the NBBO. While such orders currently rest at the near-side quote, these orders are non-displayed (i.e., not reflected in the near-side quote) and thus market participants do not know in advance whether or to what extent they may be present on IEX. Further, such orders are ranked behind other interest, and they exercise the least amount of price discretion necessary in response to an incoming active order. As the Exchange continuously updates the NBBO and calculates the midpoint thereof, it also applies its CQI functionality in an attempt to predict an in-process market move that could result imminently in a new midpoint price. In ranking a Discretionary Peg order at its resting price during this time, investors may be better able to achieve their goals of passively trading up to the most up-to-date midpoint while minimizing the adverse selection of their non-displayed interest.
The proposed change will result in Discretionary Peg orders resting at the less aggressive of one MPV less aggressive than the primary quote (or the order's limit price), rather than the primary quote itself. As these order types are non-displayed, the Commission disagrees with the commenter's assertion that, from the perspective of a seller, a Discretionary Peg order can appear to have faded its interest. As such orders are non-displayed, they cannot so appear.
Rather, resting a Discretionary Peg order at one MVP less aggressive than it currently rests is reasonably designed to further protect such orders from execution at potentially stale prices, and therefore may help users of such orders avoid subjecting them to “latency arbitrage” by those market participants using very sophisticated latency-sensitive technology who can rapidly aggregate market data feeds and react fast to changing market conditions.
As IEX notes, Discretionary Peg orders will remain subject to execution at their new, only slightly less aggressive, resting prices, which, because they are only one MPV less aggressive, still will be eligible to trade against incoming orders that are aggressively seeking liquidity slightly through the best displayed price. At the same time, their protection from algorithms that may be seeking to trade at a potentially soon-to-be stale price will be enhanced.
To the extent this enhancement incentivizes the entry of additional Discretionary Peg orders on the Exchange by better protecting them from adverse selection, it could increase overall liquidity available on the Exchange to the benefit of all market participants and provide additional opportunities for price improvement to market participants removing liquidity on the Exchange during periods of quote stability.
The Commission agrees with the commenter that the impact on displayed liquidity is an important consideration, and the Commission agrees with IEX's response that the design of the Discretionary Peg order achieves a reasonable balance in that regard. Specifically, because Discretionary Peg orders exercise the least amount of price discretion, they may trade at prices more aggressive than resting displayed orders only when the active order is priced less aggressive then the NBBO (i.e., active sell orders priced higher than the NBB or active buy orders priced lower than the NBO). As such, Discretionary Peg orders are not “jumping over” resting displayed interest on IEX because those types of incoming orders are priced such that they are not marketable against the displayed orders.
Finally, the Commission believes that the conforming changes to the description of the resting price of Discretionary Peg orders for purposes of ranking and priority in the Regular Market Session Opening Process for Non-IEX-Listed Securities is consistent with the protection of investors and the public interest because as it conforms those provisions to the change being made to the resting price of Discretionary Peg orders, which change the Commission addresses above.
Accordingly, the Commission finds that this proposed rule change, as modified by Amendment No. 1, is designed 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, in general, to protect investors and the public interest.

VI. 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 the notice of Amendment No. 1 in the Federal Register. As noted above, in Amendment No. 1, the Exchange specified that, if the Commission were to approve its proposed rule change, the Exchange would implement it within ninety (90) days of Commission approval and would provide market participants with at least 10 days of notice via a Trading Alert once a specific implementation date is determined. Because Amendment No. 1 relates to the implementation of the proposed rule change and does not make any substantive changes to the proposal, the Commission believes that good cause exists for accelerated approval of the proposed rule change, as modified by Amendment No. 1. The Commission further notes that the original proposal was subject to a 21 day comment period; and three comments were received, and considered, on the proposal. Accordingly, the Commission finds good cause, pursuant to Section 19(b)(2) of the Act,
to approve the proposed rule change prior to the 30th day after the date of publication of the notice of Amendment No. 1 in the Federal Register.
It is therefore ordered, pursuant to Section 19(b)(2) of the Act,
that the proposed rule change (SR-IEX-2018-23), as modified by Amendment No. 1, hereby is approved on an accelerated basis.
For the Commission, by the Division of Trading and Markets, pursuant to delegated authority.
