###### Securities and Exchange Commission

          - [Release No. 34-73468; File No. SR-EDGX-2014-18]

## I. Introduction

                    On July 16, 2014, EDGX Exchange, Inc. (“Exchange” or “EDGX”) 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 1.5 and Chapter XI of its rule book relating to the operation of order types and order instructions on the Exchange, trading sessions and openings and re-openings. The proposed rule change was published for comment in the                     **Federal Register**                     on July 31, 2014.[3]                                          On September 11, 2014, the Commission extended the time period for Commission action on the proposal to October 29, 2014.[4]                                          The Commission received three comment letters from the same commenter on the proposed rule change,[5]                                          as well as a letter from the Exchange regarding the first comment letter.[6]                                          On October 14, 2014, the Exchange filed Amendment No. 1 to the proposed rule change.[7]                                          On October 17, 2014, the Exchange filed Amendment No. 2 to the proposed rule change, which was later withdrawn.[8]                                          On October 17, 2014, the Exchange filed Amendment No. 3 to the proposed rule change.[9]                                          The Commission is publishing this Notice and Order to solicit comment on Amendment Nos. 1 and 3 and to approve the proposed rule change, as modified by Amendment Nos. 1 and 3, on an accelerated basis.                

## II. Background

                    The proposed rule change, as described in more detail below and in the Notice, amends Rule 1.5 and                           ( print page 65451)                        Chapter XI of the EDGX rule book, relating to: (1) The Exchange's trading sessions and hours of operation; (2) the process for initial opening and re-opening after a trading halt by adding proposed Exchange Rule 11.7, Opening Process; (3) order type, order type instructions and System [10]                                          functionality; (4) the execution priority of orders; and (5) organizational and conforming amendments.[11]                                          According to the Exchange, these changes are designed to update its rule book to reflect current system functionality and to propose four new System functionalities, as described in more detail below.[12] 

## III. Discussion and Commission Findings

                    After careful review of the proposed rule change and the comments received, the Commission finds that the proposed rule change, as modified by Amendment Nos. 1 and 3, is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange.[13]                                          In particular, as described in more detail below, the Commission finds that the proposed rule change, as modified by Amendment Nos. 1 and 3, 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 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, in general, to protect investors and the public interest. This order approves the proposed rule change in its entirety, although only certain more significant aspects of the proposed rules are discussed below.                

### A. Exchange Trading Sessions and Hours of Operation

                    Currently, Exchange Rule 11.1(a) provides that orders may be entered, executed or routed away during Regular Trading Hours, the Pre-Opening Session, and the Post-Closing Session, but does not define those terms. The Exchange proposes to add the term “Session Indicator” to codify the manner that a User [15]                                          may elect the trading sessions for which its orders are eligible for execution. The Exchange also proposes to describe the terms Regular Trading Hours, Pre-Opening Session and Post Closing Session as Session Indicators, and specify the time frames that orders with such indicators would be eligible for execution. Similarly, the Exchange proposes to add and describe the terms “Regular Session” and “All Sessions” as Session Indicators to codify additional options that a User may elect to establish the trading sessions and time frames that an order may be eligible for execution.                

Proposed Exchange Rule 11.1(a)(1), describing the term Session Indicator, specifies that all orders are eligible for execution during the Regular Session, and that orders not designated for a particular session or session would default to the Regular Session. The proposed rule also specifies that orders may be entered from 6:00 a.m. until 8:00 p.m. Eastern Time but are not eligible for execution until the start of the session selected by the User.

                    Proposed Exchange Rule 11.1(a)(1)(A) specifies that orders designated as Pre-Opening Session would be eligible for execution between 8:00 a.m. Eastern Time and 4:00 p.m. Eastern Time. Proposed Exchange Rule 11.1(a)(1)(B) specifies that orders designated as Regular Session would be eligible for execution between the completion of the Opening Process or a Contingent Open,[16]                                          whichever occurs first, and 4:00 p.m. Eastern Time. Proposed Exchange Rule 11.1(a)(1)(C) specifies that orders designated as Post-Closing Session would be eligible for execution between the start of the Regular Session and 8:00 p.m. Eastern Time. Proposed Exchange Rule 11.1(a)(1)(D) specifies that orders designated as All Sessions would be eligible for execution between 8:00 a.m. Eastern Time and 8:00 p.m. Eastern Time.                

                    The Commission believes that the proposed rules relating to the Exchange trading sessions and hours of trading are consistent with the Act. The proposed rule makes the operation of the Exchange more transparent which should benefit Members, Users, and the general investing public. The Commission also notes that the proposed rule is substantially similar to that of other exchanges.[17] 

### B. Process for Initial Opening and Re-Opening

The Exchange's current rules make various references to, but do not describe, an Opening Process. Accordingly, the Exchange proposes Exchange Rule 11.7 to codify and describe its current Opening and Re-Opening processes, with two changes, which are described below.

                    Proposed Exchange Rule 11.7(a) describes the entry and cancellation of orders before the Opening Process. Specifically, prior to the Regular Session, Users may enter orders to participate in the Opening Process. All orders are eligible to participate during the Opening Process, except (1) orders with a Stop Price [18]                                          or Stop Limit instruction,[19]                                          (2) Limit Orders with a Post Only,[20]                                          Fill-or-Kill (“FOK”) or Immediate or Cancel (“IOC”) instruction, (3) Intermarket Sweep Orders (“ISOs”) or (4) orders cancelled before the Opening Process. Orders ineligible to participate in the Opening Process, but designated for the Regular Session, would not be accepted by the System on the EDGX Book [21]                                          until the completion of the Opening Process or the initiation of a Contingent Open as set forth by proposed Exchange Rule 11.7.                

                    Proposed Exchange Rule 11.7(b) describes the execution of orders during the Opening Process. Specifically, during the Opening Process the                           ( print page 65452)                        Exchange would attempt to execute all eligible orders by matching buy and sell orders, in time sequence, at the midpoint of the NBBO, and would continue until either there were no orders to be matched or there was a remaining imbalance of orders. If the Opening Process resulted in no orders being matched, or a remaining imbalance of orders, the unexecuted orders would then be posted on the EDGX Book, canceled, executed, or routed to an away Trading Center pursuant to proposed Exchange Rule 11.11.                

                    Proposed Exchange Rule 11.7(c) describes how the opening price is determined during the Opening Process. Specifically, for securities listed on either the NYSE or NYSE MKT, the Opening Process would set the opening price at the midpoint based on the: (1) First NBBO subsequent to the first reported trade on the listing exchange after 9:30:00 a.m. Eastern Time; or (2) the prevailing NBBO when the first two-sided quotation published by the listing exchange after 9:30:00 a.m. Eastern Time, but before 9:45:00 a.m. Eastern Time if no first trade is reported by the listing exchange within one second of publication of the first two-sided quotation by the listing exchange.[22]                                          For any other listing market, the Opening Process would be priced at the midpoint of the first NBBO disseminated after 9:30:00 a.m. Eastern Time.                

Proposed Exchange Rule 11.7(d) describes the Contingent Open. A Contingent Open would result if the Opening Process did not yield an opening price by 9:45:00 a.m. Eastern Time. In such an instance, the order would either be posted to the EDGX Book, routed, canceled, or executed consistent with its order type instruction, except that a MidPoint Match (“MPM”) Order, would be ineligible for execution until an opening price had been determined pursuant to the Opening Process.

                    Proposed Exchange Rule 11.7(e) describes Re-Openings. A Re-Opening would occur after a trading halt, suspension or pause. The Re-Opening price would be the midpoint of the: (1) First NBBO subsequent to the first reported trade on the listing exchange following the resumption of trading after a halt, suspension, or pause; or (ii) then prevailing NBBO when the first two-sided quotation published by the listing exchange following the resumption of trading after a halt, suspension, or pause if no first trade is reported by the listing exchange within one second of publication of the first two-sided quotation by the listing exchange.[23] 

                    The Commission finds that the proposed rule to codify the Exchange Opening Process, Contingent Open and Re-Openings is consistent with the Act. The Commission believes that the proposed rule is reasonably designed to facilitate an orderly transition between the Pre-Opening Session and Regular Trading Hours, as well as the resumption of trading after a trading halt, suspension or pause. Finally, the Commission notes that the Exchange rule is based on ISE Rule 2106.[24] 

### C. Order Types, Order Type Instructions and System Functionality Under Chapter XI

#### 1. Definitions—Proposed Exchange Rule 11.6

                    As discussed in more detail below, proposed Exchange Rule 11.6 would relocate and reclassify various terms currently defined in the Exchange rulebook, as well as add certain other defined terms. The Exchange proposes to classify certain existing order types as “instructions” to be attached to one or more standalone order types.[25] 

                    The Commission notes that several proposed modifications to existing definitions are substantively similar to the current rule text, with added specificity, including: Attributable, Non-Attributable, Crossing Quotation, Locking Quotation, Minimum Price Variation,[26]                                          Pegged, Permitted Price, Reserve Quantity, certain routing (Destination Specified and Destination-on-Open) and time-in-force (Immediate or Cancel and Fill-or-Kill) instructions.[27]                                          Although the Exchange did not previously define Cancel Back or Displayed, the Commission notes that these terms are consistent with existing rule text.                

                    Certain other proposed modifications to existing Exchange definitions are consistent with the rules of other exchanges, including: Discretionary Range,[28]                                          Non-Displayed,[29]                                          certain routing instructions (Book Only and Post Only),[30]                                          and units of trading (Round Lot, Odd Lot and Mixed Lot).[31]                                          Similarly, a number of proposed new definitions/terms are consistent with the rules of exchanges, including: Locking Price,[32]                                          Minimum Execution Quantity,[33]                                          pegging instructions (Market Peg and Primary Peg),[34]                                          Replenishment Amount,[35]                                          time-in-force instruction of Good-'til-Time.[36]                                          Finally, several proposed new definitions/terms are consistent with the definitions contained in Commission rules Regulation SHO and Regulation NMS, including: Short Sale, Short Exempt and Trading Center. Accordingly, the Commission believes that the proposed rule changes related to these definitions/terms are consistent with the Act.                

#### a. Attributable and Non-Attributable

                    The Exchange currently defines the terms “Attributable Order” and “Non-Attributable Order” in Exchange Rules 11.5(c)(18) and (19). The Exchange proposes to reclassify these terms as order type instructions and relocate them to proposed Exchange Rule 11.6(a). In addition, the Exchange proposes to amend the terms to provide that: (1) Unless the User elects                           ( print page 65453)                        otherwise, all orders will be automatically defaulted by the System to Non-Attributable; and (2) a User may elect an order to be Attributable on an order-by-order basis or instruct the Exchange to default all its orders as Attributable on a port-by-port basis, except if a User instructs the Exchange to default all its orders as Attributable on a particular port, such User would not be able to designate any order from that port as Non-Attributable. The Exchange also proposes to provide that a User's MPID will be visible via the Exchange's Book Feed if an Attributable instruction is attached to an order and not visible if an order Non-Attributable is attached to an order.                

#### b. Cancel Back

                    The Exchange proposes to add the defined term “Cancel Back” to codify the existing function where a User may opt to have the System cancel the order at the time of receipt, in lieu of a re-pricing instruction [37]                                          to comply with Regulation NMS, Regulation SHO, or the National Market System Plan to address extraordinary market volatility (the “LULD Plan”).[38] 

#### c. Discretionary Range

                    The Exchange currently defines a “Discretionary Order” in Exchange Rule 11.5(c)(13). The Exchange proposes to reclassify this function as an order type instruction and relocate the term “Discretionary Range” to proposed Exchange Rule 11.6(d). In addition, the Exchange proposes to modify the definition of Discretionary Range to specify which order types[39]                                          may include a Discretionary Range instruction, and how the Discretionary Range operates. Specifically, the term Discretionary Range would be defined as an instruction that may accompany an order to buy (sell) a stated amount of a security at a specified, displayed price with discretion to execute up (down) to a specified, non-displayed price.[40]                                          The proposal also codifies that the Discretionary Range of an order to buy (sell) cannot be more than $0.99 higher (lower) than the order's displayed price, and that a resting order with a Discretionary Range instruction would execute at its least aggressive price when matched for execution against an incoming order with a Discretionary Range instruction, as permitted by the terms of both the incoming and resting order.                

#### d. Display Options

The Exchange proposes to include definitions of “Displayed” and “Non-Displayed” in proposed Exchange Rule 11.6(e). Currently the term Displayed is not defined within the Exchange rules. The Exchange would codify that Displayed is the default instruction for all display-eligible orders on the EDGX Book.

                    Currently, the term Non-Displayed Order is defined in Exchange Rule 11.5(c)(8). The Exchange proposes to reclassify this term as an order type instruction, and relocate the amended term to proposed Exchange Rule 11.6(e). In order to reflect its current operation, the Exchange proposes to delete the current rule language stating that the System will not accept Non-Displayed Orders that are priced better than the midpoint of the NBBO, and codify that the Exchange currently accepts orders with a Non-Displayed instruction that are priced better than the midpoint of the NBBO. The proposed rule change also codifies that an order with a Non-Displayed instruction may include a Cancel Back instruction under proposed Exchange Rule 11.6(b), or a re-pricing instruction pursuant to proposed Exchange Rule 11.6(l)(3) described below.[41]                                          The proposed definition of Non-Displayed also differs from the current definition in that it deletes rule text regarding the priority and ranking of Non-Displayed Orders because proposed Exchange Rule 11.9 sets forth the priority and ranking of all orders.                

#### e. Locking Price

                    Under current Exchange Rule 11.5(c)(4), a re-pricing instruction to comply with Regulation NMS may be triggered if an incoming order, if displayed at its limit price, would be a Locking Quotation.[42]                                          In order to specify the price that triggers a Regulation NMS re-pricing instruction the Exchange proposes to define the term, “Locking Price,” as the “price of an order to buy (sell) that, if, upon entry into the System, or upon return to the System after being routed away, and displayed by the System on the EDGX Book, it would be a Locking Quotation.” [43] 

#### f. Locking Quotation and Crossing Quotations

                    Currently, Exchange Rule 11.16 defines the terms “Locking Quotation” [44]                                          and “Crossing Quotation.” [45]                                          The Exchange proposes to relocate the amended terms, respectively, to proposed Exchange Rule 11.6(c) and (g). The amended definitions specify that the display of either a Locking or Crossing Quotation would violate Rule 610(d) of Regulation NMS and that Regulation NMS re-pricing instructions are applicable outside of Regular Trading Hours.                

#### g. Minimum Execution Quantity

                    The Exchange proposes to define the term “Minimum Execution Quantity” as an order type instruction.[46]                                          Although it is currently available, the Minimum Execution Quantity function is not currently defined by Exchange rules. The Minimum Execution Quantity would be an order type instruction, combined with a Non-Displayed instruction, which would only execute the order to the extent that a minimum quantity could be satisfied by an execution against a single order or multiple aggregated orders simultaneously. An order with a Minimum Execution Quantity instruction could partially execute if the execution size equaled or exceeded the quantity provided in the instruction. The Exchange also proposes that any shares remaining after a partial execution would continue to be executed at a size equal to or exceeding the quantity provided with the instruction, unless the User elects otherwise. The Minimum Execution                           ( print page 65454)                        Quantity instruction would not be applicable if after a partial execution the remaining shares were less than the quantity provided in the instruction.                

#### h. Minimum Price Variation

                    Exchange Rule 11.7, Price Variation, currently defines the term “Price Variation.” [47]                                          The Exchange proposes to relocate the term “Minimum Price Variation” to proposed Exchange Rule 11.6(i) and amend the term to remove the obsolete term, “indications of interest.” [48] 

#### i. Pegged

Currently the term “Pegged Order” is defined under Exchange Rule 11.5(c)(6). The Exchange proposes to reclassify the term as an instruction and relocate the term to proposed Exchange Rule 11.6(j). The amended definition of a Pegged instruction would continue to indicate that: (1) A User may specify that the order's price will peg to a price a certain amount away from the NBB or NBO (offset); (2) if an order with a Pegged instruction displayed on the Exchange would lock the market, the price of the order will be automatically adjusted by the System to one Minimum Price Variation below the current NBO (for bids) or to one Minimum Price Variation above the current NBB (for offers); (3) a new time stamp is created for the order each time it is automatically adjusted; and (4) orders with a Pegged instruction are not eligible for routing pursuant to proposed Exchange Rule 11.11.

                    The Exchange also proposes to codify that orders with Pegged instructions would not be used to calculate the NBBO, and buy/sell orders with a Pegged instruction would be cancelled when the NBB/NBO is unavailable. In addition, the Exchange would codify the terms “Primary Peg” and “Market Peg.” [49]                                          Proposed Exchange Rule 11.6(j) would specify that a Pegged instruction may be a Market Peg, which would track NBB, for a sell order, or the NBO, for a buy order; or a Primary Peg, which would track the NBB, for a buy order, or the NBO, for a sell order. The Exchange would also sets forth that a buy (sell) order with a Market Peg instruction and a Displayed instruction must have an offset that is equal to or greater than one Minimum Price Variation below (above) the NBO (NBB) that the order is pegged to.[50]                                          The amended term would also specify that if a User does not select an offset, the System would automatically include an offset that is equal to one Minimum Price Variation below (above) the NBO (NBB) that the order is pegged to. For an order with a Non-Displayed instruction, a User could, but would not be required to, select an offset for an order to buy (sell) that is equal to or greater than one Minimum Price Variation below (above) the NBO (NBB) to which the order is pegged.                

                    Proposed Exchange Rule 11.6(j) also sets forth that a buy (sell) order with a Primary Peg instruction could, but would not be required to, select an offset equal to or greater than one Minimum Price Variation [51]                                          above or below the NBB or NBO that the order is pegged to. As proposed, an order with a Primary Peg instruction would be eligible to join the Exchange's BBO if the EDGX Book was locked or crossed by another market, but if an order with a Primary Peg instruction would create a Locking Quotation or Crossing Quotation, the price of the order would be automatically adjusted by the System to one Minimum Price Variation below/above the current NBO/NBB. The Exchange also codifies that, under proposed Exchange Rule 11.6(l)(3), discussed below, an order with a Pegged and Non-Displayed instruction that is priced more aggressively than the midpoint of the NBBO, would be ranked at the midpoint with discretion to execute to the price established by the offset, or the NBB (NBO) where the offset for an order to sell (buy) is equal to or more aggressive than the NBB (NBO).[52] 

#### j. Permitted Price

                    The Exchange currently defines the term “Permitted Price” in Exchange Rule 11.5(c)(4)(B).[53]                                          The Exchange proposes to relocate the term, without amendment, to proposed Exchange Rule 11.6(k)                

#### k. Re-Pricing Instructions

                    The terms “displayed price sliding” [54]                                          and “short sale price sliding process” [55]                                          are currently defined in Exchange Rule 11.5(c)(4)(A) and (B), respectively. However, the Exchange currently offers multiple re-pricing instructions designed to permit Users to comply, separately and respectively, with Rule 610(d) of Regulation NMS or Rule 201 of Regulation SHO. The Exchange proposes to replace the definitions for displayed price sliding process and the short sale price sliding process with proposed Exchange Rule 11.6(l), which would codify three re-pricing options for Regulation NMS (Price Adjust, Hide Not Slide, and Routed and Returned Re-Pricing) and the two re-pricing options for Regulation SHO (Short Sale Price Adjust and Short Sale Price Sliding), all of which are currently available on the                           ( print page 65455)                        System.[56]                                          The Exchange also proposes to codify the re-pricing instruction for orders with a Non-Displayed instruction, which also is currently available on the System but not reflected in the current rules.                

#### i. Re-Pricing Instructions To Comply With Rule 610(d) of Regulation NMS

                    Proposed Exchange Rule 11.6(l)(1)(A) would codify the Price Adjust instruction. Specifically, under the proposed rule, a User may select, or be defaulted by the System,[57]                                          to the Price Adjust instruction where an incoming order that would be a Locking Quotation or Crossing Quotation would be displayed and ranked [58]                                          at a price that is one Minimum Price Variation lower (higher) than the Locking Price.[59]                                          Subsequently, the order would be displayed and ranked by the System on the EDGX Book at the Locking Price if the NBBO changed such that the order, if displayed at the Locking Price, would not be a Locking Quotation or Crossing Quotation, including where an ISO with a time-in-force (“TIF”) instruction of Day is entered into the System and displayed on the EDGX Book on the same side of the market as the order at a price that is equal to or more aggressive than the Locking Price.[60]                                          The order would not be subject to further re-ranking and would be displayed by the System on the EDGX Book at the Locking Price until executed or cancelled by the User. The order would receive a new time stamp at the time an order is re-ranked.[61]                                          Pursuant to proposed Exchange Rule 11.9, all orders that are re-ranked and re-displayed pursuant to the Price Adjust instruction would retain their comparative priority based on the time of initial receipt by the System.[62] 

                    Proposed Exchange Rule 11.6(l)(1)(B) would codify the Hide Not Slide instruction. Specifically, under the proposed rule, if a User selects the Hide Not Slide instruction, an incoming order that would be a Locking Quotation or Crossing Quotation would be displayed at a price that is one Minimum Price Variation lower (higher) than the Locking Price and ranked at the midpoint of the NBBO with discretion to execute at the Locking Price; provided, however, that if at the time of entry a contra-side order equal to the Locking Price is displayed by the System, the order would be ranked at the midpoint of the NBBO with its discretion to execute to the Locking Price suspended. Discretion to execute to the Locking Price would remain suspended until the contra-side displayed order equal to the Locking Price is cleared. Where the NBBO changes such that the order, if displayed at the Locking Price would not be a Locking Quotation, the System would rank and display the order at the Locking Price. Thereafter, the order would not be subject to further re-ranking and would be displayed by the System at the Locking Price until it is executed or cancelled by the User. The order would receive a new time stamp when it is ranked at the Locking Price. Pursuant to proposed Exchange Rule 11.9, all orders that are re-ranked and re-displayed by the System pursuant to the Hide Not Slide instruction would retain its comparative priority based upon the time of initial receipt by the System.[63] 

                    Proposed Exchange Rule 11.6(l)(1)(B)(i) would codify the Routed and Returned Re-Pricing instruction. Specifically, under the proposed rule, if a Limit Order was routed away but not fully executed, the returning remainder of the order, if it would be a Locking Quotation or Crossing Quotation of a quotation displayed by another Trading Center upon re-entry to the System, would default to a Routed and Returned Re-Pricing instruction, unless the User selected either the Cancel Back, Price Adjust or Hide Not Slide instruction.[64]                                          The Routed and Returned Re-Pricing instruction would cause the returning order, that would otherwise be a Locking Quotation or Crossing Quotation based on an away market, to re-price one Minimum Price Variation away from the Locking Price, be ranked at the midpoint of the NBBO, with discretion to execute at the Locking Price. If a contra-side order with a Post Only instruction that equals the Locking Price is subsequently entered and displayed by the System, the order subject to the Routed and Returned Re-Pricing instruction would be ranked at the midpoint of the NBBO with its discretion to execute at the Locking Price suspended until there is no contra-side order displayed by the System equals the Locking Price.[65]                                          Thereafter, in response to changes in the NBBO, an order subject to the Routed and Returned Re-Pricing instruction would be adjusted and displayed by the System at one Minimum Price Variation below (above) the NBO (NBB) and ranked at the updated midpoint of the NBBO with discretion to execute at the Locking Price until the price of such order reached its limit price; at which point the order would be displayed at the limit price by the System without further adjustment. Upon return to the EDGX Book after being routed away, the order will execute against any marketable contra-side liquidity on the EDGX Book and any remainder will be subject to the Routed and Returned Re-Pricing instruction.[66]                                          The order would receive a new time stamp upon returning to the EDGX Book and upon each subsequently re-ranking. Pursuant to proposed Exchange Rule 11.9, all orders that are re-ranked and re-displayed pursuant to the Routed and Returned Re-Pricing instruction would retain their comparative time priority at a price level based upon the time of initial re-entry to the System.[67] 

                    The Commission finds that the proposed rules related to Regulation NMS re-pricing are consistent with                           ( print page 65456)                        Section 6(b)(5) of the Act,[68]                                          and the rules and regulation thereunder, including Rule 610 of Regulation NMS.” [69]                                          The operation of Price Adjust, Hide Not Slide and Routed and Returned Re-Pricing are consistent with Rule 610(d) of Regulation NMS as they should prevent members from displaying orders that lock or cross any protected quotation in an NMS stock.[70]                                          In addition, the Commission notes that other exchanges offer price-sliding functionality to comply with Regulation NMS.[71] 

#### ii. Re-Pricing Instructions To Comply With Rule 201 of Regulation SHO

                    Proposed Exchange Rule 11.6(l)(2) sets forth the following re-pricing instructions for an order with a Short Sale instruction to comply with Rule 201 of Regulation SHO: (1) Short Sale Price Adjust and (2) Short Sale Price Sliding. Under the proposal, a Limit Order to sell with a Short Sale instruction that cannot display or execute at its limit price at the time of entry because of a short sale price restriction pursuant to Rule 201 of Regulation SHO (“Short Sale Circuit Breaker”),[72]                                          would automatically default to the Short Sale Price Adjust instruction, unless the User affirmatively elects: (1) The Cancel Back instruction; or (2) the Short Sale Price Sliding instruction. Like current Exchange Rule 11.5(c)(4)(E), orders to sell with both a Short Sale and a Short Exempt instruction would not be eligible for any of the Regulation SHO re-pricing instructions and instead would execute, display and/or route without regard to whether the order is at a Permitted Price or if a Short Sale Circuit Breaker in effect. In addition, when a Short Sale Circuit Breaker is in effect and the incoming order has a Short Sale instruction, Regulation SHO re-pricing instructions would supersede Regulation NMS re-pricing instructions.                

                    Proposed Exchange Rule 11.6(l)(2)(A) would codify the Short Sale Price Adjust instruction. If selected by a User and a Short Sale Circuit Breaker was in effect, the sell order with a Short Sale instruction would be ranked and displayed at the Permitted Price.[73]                                          Following the initial ranking, the order, to the extent the NBB declines, would continue to be re-ranked and displayed at the Permitted Price down to the order's limit price. The order would receive a new time stamp each time it is re-ranked. All orders with Short Sale Price Adjust instructions that are re-ranked and re-displayed by the System would retain their comparative time priority based on their initial receipt by the System.[74] 

                    Proposed Exchange Rule 11.6(l)(2)(B) would codify the Short Sale Price Sliding instruction. If selected by a User and a Short Sale Circuit Breaker was in effect, the sell order with a Short Sale instruction would be displayed at the Permitted Price and ranked at the midpoint of the NBBO. Following the initial ranking, the order would, to the extent the NBB declined, be re-ranked and re-displayed with a new time stamp one additional time at a price equal to the NBB at the time of the order's original entry.[75] 

                    The Commission finds that the proposed rules related to Regulation SHO re-pricing are consistent with Section 6(b)(5) of the Act,[76]                                          as well as Rule 201 of Regulation SHO.[77]                                          Rule 201 of Regulation SHO requires trading centers to establish, maintain, and enforce written policies and procedures reasonably designed to prevent the execution or display of a short sale order at a price at or below the current NBB when a Short Sale Circuit Breaker is in effect, subject to certain exceptions.[78]                                          Pursuant to the Exchange's rules relating to Short Sale Price Adjust and Short Sale Price Sliding, sell orders with a Short Sale instruction that cannot be executed or displayed in compliance with Rule 201 of Regulation SHO would be displayed at the Permitted Price (                    *i.e.,*                     above the current NBB). In addition, the Commission notes that Short Sale Price Adjust [79]                                          and Short Sale Price Sliding [80]                                          operate in a manner that is substantially similar to other exchanges.                

                    The Commission notes that Short Sale Price Sliding permits sell orders with a Short Sale instruction to be ranked at the midpoint of the NBBO and displayed at the Permitted Price. The Commission finds that Regulation SHO re-pricing to permit an order with a Short Sale instruction to be executed at the midpoint of the NBBO, and displayed above the NBB, is consistent with Rule 201 of Regulation SHO.[81] 

#### iii. Re-Pricing of Orders With a Non-Displayed Instruction

                    Proposed Exchange Rule 11.6(l)(3) would codify the re-pricing of orders with a Non-Displayed instruction to specify that an order with a Non-Displayed instruction that is priced better than the midpoint of the NBBO, would be ranked at the midpoint of the NBBO with discretion to execute to its limit price.[82]                                          In response to changes in the NBBO, an order with a Non-Displayed instruction would be automatically re-ranked, with a new time stamp, until the midpoint of the NBBO reached the order's limit price. A User may elect the Cancel Back instruction for a buy (sell) order with a Non-Displayed instruction where the limit price is greater (less) than the NBO (NBB). Pursuant to proposed Exchange Rule 11.9, all orders with a Non-Displayed instruction that are re-ranked at the midpoint of the NBBO would retain their comparative time priority based upon their initial ranking at the midpoint of the NBBO.[83] 
      ( print page 65457)    

#### l. Reserve Quantity and Replenishment Amounts

                    Exchange Rule 11.5(c)(1) currently defines a “Reserve Order” as “[a] limit order with a portion of the quantity displayed (`display quantity') and with a reserve portion of the quantity (`reserve quantity') that is not displayed.” The Exchange proposes to reclassify this function as an order type instruction and relocate the term “Reserve Quantity” to proposed Exchange Rule 11.6(m). The term Reserve Quantity would be defined to mean the portion of an order with a Non-Displayed instruction in which a portion of that order is also displayed on the EDGX Book. The Exchange also would specify that both the portion of the order with a Displayed instruction and the Reserve Quantity of the order are available for execution against incoming orders. The Exchange also specifies that where the displayed quantity of an order is reduced to less than a Round Lot, the System, in accordance with the replenishment instruction selected by the User, would replenish the displayed quantity from the Reserve Quantity by at least a single Round Lot. A new time stamp would be created for the displayed portion of the order each time it is replenished from the Reserve Quantity, and the Reserve Quantity would retains its original time stamp of its original entry.[84]                                          In addition, the Exchange states that where the combined amount of the displayed quantity and Reserve Quantity of an order is less than one Round Lot, the order would be treated as an order with a Displayed instruction for purposes of execution priority under proposed Exchange Rule 11.9.                

                    Proposed Exchange Rule 11.6(m) also codifies the two replenishment instructions [85]                                          currently offered by the Exchange: (1) Fixed Replenishment; and (2) Random Replenishment. The Fixed Replenishment instruction sets forth that the displayed quantity of an order would be replenished by a fixed quantity designated by the User. The Fixed Replenishment quantity for the order would equal the initial displayed quantity designated by the User. The displayed replenishment quantity selected by the System could not be less than a single Round Lot or greater than the remaining Reserve Quantity. Under proposed Exchange Rule 11.8(b)(5), the System would automatically default the order to the Fixed Replenishment instruction with a replenishment value equal to the displayed quantity of the order.                

                    Under the Random Replenishment instruction, the displayed quantity, both initial and replenished, would be randomly determined by the System within a replenishment range and replenishment value established by the User. The System would randomly select random display in Round Lots based on: (1) The quantity around which the replenishment range is established minus the replenishment value; and (2) the quantity around which the replenishment range is established plus the replenishment value. The displayed replenishment quantity could not: (1) Exceed the remaining Reserve Quantity of the order; (2) be less than a single Round Lot; or (3) greater than the remaining Reserve Quantity.[86] 

#### m. Routing/Posting Instructions

In proposed Exchange Rule 11.6(n), the Exchange proposes to define the following routing and posting instructions that a User may select, depending on the order type: (1) Aggressive or Super Aggressive; (2) Book Only; (3) Post Only; (4) Destination Specified; and (5) Destination-on-Open.

The Exchange proposes to codify the terms Aggressive and Super Aggressive. Aggressive is an order instruction that directs the System to route such order if an away Trading Center crosses the limit price of the order resting on the EDGX Book. Super Aggressive is an order instruction that directs the System to route such order if an away Trading Center locks or crosses the limit price of the order resting on the EDGX Book.

                    Current Exchange Rule 11.5(c)(4) defines the term EDGX Only Order.[87]                                          The Exchange proposes to reclassify this function as an order type instruction and relocate the amended definition and term “Book Only” to proposed Exchange Rule 11.6(n)(3). The proposed definition of Book Only would specify that it is: “[a]n order instruction stating that an order will be matched against an order on the EDGX Book or posted to the EDGX Book, but will not route to an away Trading Center.” [88]                                          References to the Exchange's “display price sliding process and short sale price sliding process” would be removed from the amended Book Only definition because, as noted above, proposed Exchange Rule 11.6(l) is proposed to now describe re-pricing instructions for Regulation NMS and Regulation SHO compliance.                

                    Current Exchange Rule 11.5(c)(5) defines the term “Post Only Order.” [89]                                          The Exchange proposes to reclassify this function as an order type instruction and relocate the amended definition and term “Post Only” to proposed Exchange Rule 11.6(n)(4). Currently, the Post Only definition specifies that order would not remove liquidity from the EDGX Book unless “the User enters an instruction to the contrary.” The Exchange proposes amend the definition to specify that an order with a Post Only instruction may remove contra-side liquidity from the EDGX Book when combined with a Hide Not Slide or a Price Adjust instruction if the order is for a security priced below $1.00 or the value of such execution, including any fees charged or rebates provided, equals or exceeds the value of such execution if the order instead posted and provided liquidity.[90]                                          In addition, the Exchange proposes to remove references to Exchange's “display price sliding process and short sale price sliding process” from the amended Post Only definition because, as noted above, proposed Exchange Rule 11.6(l) is proposed to describe re-pricing instructions for Regulation NMS and Regulation SHO compliance.                

                    Exchange Rule 11.5(c)(9) currently defines the term “Destination Specific                           ( print page 65458)                        Order.” [91]                                          The Exchange proposes to reclassify this function as an order type instruction and relocate the amended definition and term “Destination Specified” to proposed Exchange Rule 11.6(n)(4). The amended definition would provide that an order with a Destination Specified instruction may be processed as described in proposed Exchange Rule 11.10(a)(4), returned to the User, or posted to the EDGX Book, unless the User instructs that the order reside on the book of the relevant away Trading Center.                

Exchange Rule 11.5(c)(10) currently defines the term “Destination-on-Open Order.” The Exchange proposes to reclassify this function as an order type instruction and relocate the amended definition and term “Destination-on-Open” to proposed Exchange Rule 11.6(n)(6). The amended definition would state that a Destination-on-Open instruction may be appended to a Market or a Limit Order and that an unfilled portion of an order with a Destination-on-Open instruction may be cancelled or re-routed.

#### n. Short Sale and Short Exempt

                    Currently, certain current Exchange rules refer to the terms “short sale order” and “short exempt,” [92]                                          but neither term is specifically defined. Proposed Exchange Rules 11.6(o) and 11.6(p) would respectively provide definition for the terms “Short Sale” and “Short Exempt.” The proposed definitions for Short Sale instruction and Short Exempt instruction would be consistent with Rules 200(a) and 201 of Regulation SHO.[93] 

#### o. Time-In-Force

                    Current Exchange Rule 11.5(b)(1)-(3) defines the terms “IOC Order,” “Day Order” and “Fill-or-Kill Order.” [94]                                          The Exchange proposes to reclassify these terms as time-in-force order type instructions and relocate the definitions, IOC, Day, FOK and Good-`til Time (“GTT”), to proposed Exchange Rule 11.6(n)(4). The proposed rule specifies that an order with a TIF instruction of Day entered into the System before the start of the specified trading session would be placed by the System in a pending state and activated for potential execution upon the start of that trading session.                

                    The Exchange proposes to include a new TIF instruction, GTT, which could be appended to an order in any trading session with instructions to cancel at a specified time of day. The proposed rule also sets forth that an order with a GTT instruction would not be eligible for execution over multiples days [95]                                          and that any unexecuted portion of such order with a GTT would be cancelled at: (1) The expiration of the User's specified time; (2) at the end of the User's specified trading session(s); or (3) the end of the trading day, as instructed by the User. As proposed, order with a GTT instruction would not be eligible for execution over multiple trading days.                

#### p. Trading Center

                    The Exchange proposes to add the term “Trading Center” to proposed Exchange Rule 11.6(r) to be defined as “[o]ther securities exchanges, facilities of securities exchanges, automated trading systems, electronic communications networks or other brokers or dealers.” [96]                                          The term would be consistent with the Trading Center definition of in Rule 600(a)(78) of Regulation NMS.[97] 

#### q. Units of Trading

Current Exchange Rule 11.6 provides that “[o]ne hundred (100) shares shall constitute a `round lot,' any amount less than 100 shares shall constitute an `odd lot,' and any amount greater than 100 shares that is not a multiple of a round lot shall constitute a `mixed lot.'” The Exchange proposes to relocate the definition of “Units of Trading” to proposed Exchange Rule 11.6(s). The relocated and amended definition would provide that a Round Lot is 100 shares, unless an alternative number of shares is established as a Round Lot by the listing exchange for the security. Similarly, in proposed Exchange Rule 11.9(a)(6)), the Exchange proposes a conforming change to replace the term “99 shares or fewer” with “less than a Round Lot.” Proposed Exchange Rule 11.6(s) would also state that Round Lots are eligible to be Protected Quotations.

Current Exchange Rule 11.5(c)(2) defines the term an “Odd Lot Order” as “[a]n order to buy or sell an odd lot.” The Exchange proposes to revise and relocate the term to proposed Exchange Rule 11.6(s)(2). The definition would be amended to indicate that an Odd Lot is “[a]ny amount less than a Round Lot,” and that orders of Odd Lot size are only eligible to be Protected Quotations if aggregated to form a Round Lot.

                    Current Exchange Rule 11.5(c)(3) defines the term a “Mixed Lot Order.” The Exchange proposes to revise and relocate the term to proposed Exchange Rule 11.6(s)(3). The definition would be amended to indicate that “[a]ny amount greater than a Round Lot that is not an integer multiple of a Round Lot,” and that the Odd Lot portions of an order of Mixed Lot size are only eligible to be Protected Quotations if aggregated to form a Round Lot.[98] 

#### 2. Order Types—Proposed Exchange Rule 11.8

                    The Exchange has determined that the majority of the existing individual order types should be reclassified as order type instructions to be attached to specific, standalone order types.[99]                                          Accordingly, the Exchange proposes to delete and replace current Exchange Rule 11.5 with proposed Exchange Rule 11.8, Order Types,[100]                                          which would outline the characteristics of the six order types that would be accepted by the System: (1) Market Orders, (2) Limit Orders, (3) ISOs, (4) MidPoint Match Orders, (5) NBBO Offset Peg Orders, and (6) Route Peg Orders.                

                    The Commission finds that the proposed rules relating to the definitions and descriptions of order types are consistent with the Act. The Commission notes that the definitions and operations of Market Order, Limit Order, ISO, and MPM Order are substantively similar to the current rule text, with added specificity related to the operation of the standalone order type and the order type instructions that may be attached thereto. The NBBO Offset Peg Order and Route Peg Order are currently offered by the Exchange, and the related rule text has been relocated and reformatted to conform to                           ( print page 65459)                        the reorganization of the Exchange rule book without substantive amendment. Accordingly, the Commission believes that these proposed rule changes are consistent with the Act.                

#### a. Market Order

Current Exchange Rule 11.5(a)(2) defines the term “Market Order.” The Exchange proposed to relocate the term to proposed Exchange Rule 11.8(a), and revise it to include additional language describing the operation of the order type and the order type instructions that may be attached thereto.

                    Specifically, proposed Exchange Rule 11.8(a) would define a Market Order as “[a]n order to buy or sell a stated amount of a security that is to be executed at the NBBO or better when the order reaches the Exchange.” The proposed rule also specifies that Market Orders are eligible to execute during the Regular Session; ineligible to execute during the Pre-Opening or the Post-Closing Trading Sessions; may be an Odd Lot, Round Lot, or Mixed Lot; and may include a Stop Price instruction. Proposed Exchange Rule 11.8(a)(2) would specify that a Market Order would default to a TIF instruction of Day, unless otherwise instructed by the User; and that in addition to Day, a User could append a Market Order with an IOC or FOK instruction. The proposed rule also sets forth that a Market Order with a FOK instruction would cancel if not executed in full portion immediately after entry [101]                                          and that a Market Order with an IOC instruction would cancel any unexecuted portion of the order after checking the System for available shares, and, if applicable, upon return to the System after being routed to an away Trading Center. The proposed rule also specifies that a Market Order that does not include a Book Only, IOC or FOK instruction and cannot be executed in accordance with proposed Exchange Rule 11.10(a)(4) would be eligible for routing pursuant to proposed Exchange Rule 11.11.[102] 

                    Under the proposed rules, a Market Order would post to the book in certain instances. Under proposed Exchange Rule 11.10(a)(3)(A), where the NBO/NBB is greater/lesser than the Upper/Lower Price Band, an incoming non-routable buy/sell Market Order would post to the EDGX Book at a price equal to the Upper (Lower) Price Band, unless appended with a TIF instruction of IOC or FOK or a Cancel Back instruction.[103]                                          Under Proposed Exchange Rule 11.8(a)(4), a Market Order appended with both a Day and a Short Sale instruction that could not execute because of a Short Sale Restriction, would display pursuant to the Short Sale Price Sliding instruction.[104] 

Under the proposed rules, there are also certain instances when a Market Order would cancel instead of execute. The proposed rule specifies that if a Market Order with a Book Only instruction is re-priced when the NBO/NBB is greater/less than the Upper/Lower Price Band, the order would be cancelled pursuant to proposed Exchange Rule 11.10(a)(4). The Exchange also specifies that, except for a Market Order that include a Destination-on-Open instruction, any portion of a Market Order that would execute at a price more than the greater of $0.50 or five percent worse than the consolidated last sale as published by the responsible single plan processor at the time the order is entered into the System, would be cancelled.

#### b. Limit Order

                    Current Exchange Rule 11.5(a)(1) defines a Limit Order as, “[a]n order to buy or sell a stated amount of a security at a specified price or better” and a “marketable” Limit Order as a “limit order to buy (sell) at or above (below) the lowest (highest) Protected Offer (Bid) for the security.” The term would be relocated to proposed Exchange Rule 11.8(b), and be amended to include additional language describing the operation of the order type and the order type instructions that may be attached thereto. The proposed rule specifies that a Limit Order is eligible for execution during the Pre-Opening Session, Regular Session, and the Post-Closing Session, and could be an Odd Lot, Round Lot or Mixed Lot. A Limit Order could also be appended with the applicable combination of the following order type instructions: [105]                                          IOC, FOK, Day, GTT, Displayed, Non-Displayed, Attributable, Non-Attributable, Post Only, Book Only, Discretionary Range, Reserve Quantity, Pegged, Minimum Execution Quantity, Stop Limit, Destination Specified, Destination-on-Open instruction, Aggressive or Super Aggressive.                

                    Proposed Exchange Rule 11.8(b)(7) specifies that a marketable Limit Order would be eligible to be routed pursuant to proposed Exchange Rule 11.11, unless it was appended with a Post Only, Book Only or Pegged instruction.[106] 

#### c. Intermarket Sweep Order

                    Current Exchange Rule 11.5(d)(1), specifies that the System accepts incoming ISOs (as such term is defined in Regulation NMS) and that to be eligible for treatment as an ISO, the order must be: (1) A Limit Order; (2) marked ISO; and (3) the User entering the order must simultaneously route one or more additional Limit Orders marked ISO, if necessary, to away markets to execute against the full displayed size of any Protected Quotation for the security with a price that is superior to the limit price of the ISO entered in the System. Such orders, if they meet the requirements of the foregoing sentence, may be executed at one or multiple price levels in the System without regard to Protected Quotations at away Trading Centers consistent with Regulation NMS (                    *i.e.,*                     may trade through such quotations). The term would be relocated to proposed Exchange Rule 11.8(c), and amended to include additional language describing the operation of the order type and the order type instructions that may be attached thereto. Proposed Exchange Rule 11.8(c) would continue to instruct Members that the Exchange relies on, and it is the Member's responsibility, to properly mark ISOs, to satisfy the compliance requirements of Regulation NMS.[107]                                          The proposed Rule also specifies that a User entering an ISO with a Day instruction is representing that it has simultaneously routed one or more additional ISOs, if necessary, to away Trading Centers to execute against the full displayed size of any Protected Quotation for the security with a price that is superior or equal to the limit price of the ISO entered in the System.[108] 
      ( print page 65460)    
Proposed Exchange Rule 11.8(c)(4) would also specify that incoming ISOs may be submitted during the Pre-Opening Session, Regular Session, and Post-Closing Session. Proposed Exchange Rule 11.8(c)(1)-(4) would also state that an incoming ISO will have a default TIF instruction of Day, unless the User selects a TIF instruction of GTT or IOC. Incoming ISOs cannot include a TIF instruction of FOK. The proposed Rule also sets forth that an incoming ISO with a Post Only and TIF instruction of GTT or Day, but without a Price Adjust or Hide Not Slide instruction, would be rejected if, marketable against a resting order with a Displayed instruction. Any unfilled portion of an ISO with a TIF instruction of GTT or Day would be posted at the ISO's limit price on the EDGX Book.

Proposed Exchange Rule 11.8(c) would specify that an ISO with a Post Only instruction and TIF instruction of GTT or Day may also be appended with Regulation NMS or Regulation SHO re-pricing instructions.

                    Proposed Exchange Rule 11.8(c)(7) would permit a User to attach an instruction to an outbound ISO in order to permit that ISO to be immediately routed to an away Trading Center.[109]                                          However, pursuant to proposed Exchange Rule 11.11, inbound ISOs would not be eligible for routing under any circumstances.                

#### d. MidPoint Match Order

                    Exchange Rule 11.5(c)(7) currently defines an MPM Order as “[a]n order with an instruction to execute it at the midpoint of the NBBO.” The term would be relocated to proposed Exchange Rule 11.8(d), and amended to include additional language describing the operation of the order type and the order type instructions that may be attached thereto. The MPM Order definition would be amended to specify that it could be a Market Order or a Limit Order, as well as to indicate that the limit price of an MPM order would represent the highest/lowest price at which order may buy/sell.[110]                                          The proposed rule would also set forth that notwithstanding the co-designation as a Market or Limit Order, the operation of the MPM Order would be governed by proposed Exchange Rule 11.8(d).                

Proposed Exchange Rule 11.8(d)(1) specifies that an MPM Order could be appended with a TIF instruction of Day, FOK, IOC, or GTT. Proposed Exchange Rule 11.8(d)(2) specifies that an MPM Order could include a Minimum Execution Quantity instruction. Proposed Exchange Rule 11.8(d)(3) specifies that MPM Orders would default to a Non-Displayed instruction and are not eligible to include a Displayed instruction. Proposed Exchange Rule 11.8(d)(5) specifies that, pursuant to proposed Exchange Rule 11.11, MPM Orders are ineligible for routing.

Pursuant to the proposed rule, MPM Orders may only be executed during the Regular Session, and any unexecuted portion of a resting MPM Order with a Day or GTT instruction would receive a new time stamp each time it is re-priced in response to changes to the midpoint of the NBBO. However, an incoming or resting MPM Order would be ineligible for execution if there was a Locking Quotation or Crossing Quotation. The ability of the resting or incoming MPM Order to execute would resume, and the order would receive a new time stamp, when the locked/crossed condition was resolved and a new midpoint relative to the NBBO was established, the MPM Order would receive a new time stamp. Similarly, MPM Orders would be ineligible to execute if the midpoint of the NBBO was below the Lower Price Band or above the Upper Price Band. Pursuant to proposed Exchange Rule 11.9, all MPM Orders would retain their comparative priority based upon order's initial receipt and ranking at the midpoint of the NBBO.

The proposed rule would also specify that MPM Orders are eligible to participate in the Opening Process; but ineligible to participate in the Pre-Opening Session, Post-Closing Session, or the Contingent Open pursuant to proposed Exchange Rule 11.7(d). Pursuant to proposed Exchange Rule 11.7(d), if there is a Contingent Open an MPM Order would remain ineligible to trade during the Regular Session until a price for an Open Transaction has been determined pursuant to proposed Exchange Rule 11.7(c).

#### e. NBBO Offset Peg Order

                    Exchange Rule 11.5(c)(15) currently defines the NBBO Offset Peg Order. The term would be relocated to proposed Exchange Rule 11.8(e) and reformatted, without substantive amendment. The NBBO Offset Peg Order would continue to be defined as a Limit Order that, upon entry, is automatically priced by the System at the Designated Percentage [111]                                          away from the current NBB/NBO for a buy/sell order, or if there is no NBB/NBO, at the Designated Percentage away from the last reported sale from the responsible single plan processor. The proposed rule would specify that notwithstanding its co-designation as a Limit Order, the operation of an NBBO Offset Peg Order would be governed by proposed Exchange Rule 11.8(e).                

                    The proposed rule also sets forth that the price of an NBBO Offset Peg Order bid or offer would automatically adjust to the Designated Percentage away from the current NBB/NBO; or if there is no current NBB/NBO, to the Designated Percentage away from the last reported sale from the responsible single plan processor, upon reaching the Defined Limit.[112]                                          The proposed rule also sets forth that if an NBBO Offset Peg Order moves a specified number of percentage points away from the Designated Percentage toward the current NBB/NBO, the price of such bid/offer would automatically adjust the Designated Percentage away from the current NBB/NBO; or if there is no current NBB/NBO, the order would automatically adjust to the Designated Percentage away from the last reported sale from the responsible single plan processor. Pursuant to the proposed rule, cancellation or rejection would result if the order exceeded its limit price due to an NBBO Offset Peg Order being priced at the Designated Percentage away from the current NBB/NBO; or, if there is no current NBB/NBO, to the Designated Percentage away from the last reported sale from the responsible single plan processor. As proposed, the absence of a current NBB/NBO and last sale reported by the responsible single plan processor would also cause the order to be cancelled or rejected.                

                    Under the proposed rule, if a resident NBBO Offset Peg Order was priced based on the last sale reported by the responsible single plan processor and such NBBO Offset Peg Order is established as the NBB/NBO, the NBBO Offset Peg Order would not adjust until either new last sale reported by the                           ( print page 65461)                        responsible single plan processor, or a new NBB/NBO was established by a national securities exchange. However, if a Crossing Quotation existed, the NBBO Peg Offset Order would automatically price at the Designated Percentage [113]                                          (away from the current NBO/NBB for a buy/sell order).                

The proposed rule sets forth that NBBO Offset Peg Orders may only include a TIF instruction of Day; may only be Round Lots or Mixed Lots; are defaulted by the System to a Displayed instruction and are not eligible to include a Non-Displayed instruction; and may be submitted at the beginning of the Pre-Opening Session, but are not executable or automatically priced until after the first regular way last sale on the relevant listing exchange for the security, as reported by the responsible single plan processor. In addition the rule sets forth that NBBO Offset Peg Orders would receive a new time stamp each time it re-prices in response to changes in the NBB, NBO, or last reported sale; would be ineligible for routing pursuant to proposed Exchange Rule 11.11; and would expire at the end of the Regular Session. Finally, pursuant to Exchange Rule 11.20(d), irrespective of the NBBO Offset Peg Order, and consistent with its obligations, Market Makers would continue to be responsible for entering, monitoring, and re-submitting, as applicable, quotations.

#### f. Route Peg Order

Exchange Rule 11.5(c)(17) currently defines the term Route Peg Order. The term would be relocated to proposed Exchange Rule 11.8(f) and reformatted to conform to other rule changes, without substantive amendment. The Route Peg Order is a passive, resting order that does not remove liquidity or execute at a price inferior to a Protected Quotation. The Route Peg Order would be defined as a non-displayed Limit Order that is eligible for execution at the NBB for a buy order and NBO for a sell order against an order that is in the process of being routed to away Trading Centers with an order size equal to or less than the aggregate size of the Route Peg Order interest available at that price. The proposed rule would specify that notwithstanding its co-designation as a Limit Order, the operation of a Route Offset Peg Order would be governed by proposed Exchange Rule 11.8(f).

The proposed rule would also set forth that Route Peg Orders may only have a TIF instruction of GTT or Day and would be ineligible to include a TIF instruction of IOC or FOK; may only be Round Lots or Mixed Lots; would default to, and could be appended with a Non-Displayed instruction; but not with the Displayed instruction. In addition, the proposed rule sets forth that the Route Peg Order could include a Minimum Execution Quantity but is ineligible for routing pursuant to proposed Exchange Rule 11.11.

The proposed rule also set forth that Route Peg Orders may be entered, cancelled, and cancelled/replaced prior to and during the Regular Session and all unexecuted portions thereof are cancelled at the end of the Regular Session. Route Peg Orders would only be eligible for execution in a given security during the Regular Session, except during the Opening Session and until orders in a given security can be posted on the EDGX Book during the Regular Session. Route Peg Orders would also be ineligible for execution if a Locking Quotation or Crossing Quotation existed; however the ability of the Route Peg Order to execute would resume once the locked/crossed condition was cleared.

### D. Execution Priority of Orders

#### 1. Priority—Proposed Exchange Rule 11.9

Current Exchange Rule 11.8 sets forth the priority of order executions. The Exchange proposes to relocate the provision to proposed Exchange Rule 11.9 and to amend it to codify and state the following: (1) The priority of orders at certain price points; (2) the priority of Limit Orders with a Reserve Quantity; and (3) certain other conforming and clarifying changes. The Exchange states that its proposed amendments outline current System functionality in the Exchange's Rules.

                    Under Exchange Rule 11.9(a), orders of Users are first ranked and maintained by the System on the EDGX Book according to their price. Orders at the same price and of the same type are then ranked by the System depending on the time they were entered into the System. The Exchange proposes to amend Exchange Rule 11.9 to specify how orders with certain order type instructions are ranked by the System: [114]                                          (1) At a price other than the midpoint of the NBBO; (2) at the midpoint of the NBBO; and (3) where buy (sell) orders utilize instructions that cause them to be ranked by the System upon clearance of a Locking Quotation.[115]                                          The Exchange also proposes to provide that, for purposes of priority under Exchange Rule 11.9(a)(2)(A) and (B): (1) An ISO [116]                                          and NBBO Offset Peg Order [117]                                          are to be treated as Limit Orders; [118]                                          and (2) orders subject to a re-pricing instruction to comply with Rule 201 of Regulation SHO under proposed Exchange Rule 11.6(l)(2), including Market Orders that are displayed on the EDGX Book pursuant to proposed Exchange Rule 11.8(a)(4) and proposed Exchange Rule 11.10(a)(3)(A), maintain the same priority as Limit Orders at that price.                

#### 2. Prices Other Than the Midpoint of the NBBO

                    Current Exchange Rule 11.8(a)(2) states, in sum, that the System shall execute equally priced trading interest in time priority in the following order: (1) Displayed size of limit orders; (2) MidPoint Match Orders; (3) Non-displayed limit orders and reserve orders; (4) Discretionary range of Discretionary Orders as set forth in current Exchange Rule 11.5(c)(13); and (5) Route Peg Orders as set forth in current Exchange Rule 11.5(c)(17). The Exchange proposes to amend the above priority to state that it applies to equally priced trading interest at prices other than at the midpoint of the NBBO or where orders are re-ranked at the Locking Price after a Locking Quotation clears.[119]                                          As amended, proposed Exchange Rule 11.9(a)(2)(A) would state that the System will execute equally priced trading interest within the System at prices, other than at the midpoint of the NBBO or where orders are re-ranked at the Locking Price after a Locking Quotation clears, in time priority in the following order: (1) The portion of a Limit Order with a Displayed instruction; (2) Limit Orders with a Non-Displayed instruction and the Reserve Quantity of Limit Orders; (3) Limit Orders executed within their Discretionary Range; and (4) Route Peg Orders.[120] 
      ( print page 65462)    

#### 3. At the Midpoint of the NBBO

                    The Exchange also proposes to outline a separate priority for orders ranked at the midpoint of the NBBO under proposed Exchange Rule 11.9(a)(2)(B). Where orders are priced at the midpoint of the NBBO, the first order priced at the midpoint of the NBBO within each of the categories set forth in paragraphs (i) through (iv) of proposed Exchange Rule 11.9(a)(2)(B) shall have precedence at the midpoint of the NBBO, up to the number of shares of stock specified in the order. The System shall execute trading interest priced at the midpoint of the NBBO within the System in time priority in the following order: (1) Limit Orders to which the Hide Not Slide or Routed and Returned Re-Pricing instruction has been applied; (2) MidPoint Match Orders; (3) Limit Orders with a Non-Displayed instruction; and (4) Limit Orders executed within their Discretionary Range.[121] 

#### 4. Orders Re-Ranked Upon Clearance of a Locking Quotation

                    The Exchange also proposes to outline a priority of orders for orders that utilize instructions that result in their being re-ranked upon clearance of a Locking Quotation. In such case, the System re-ranks and displays such orders at the Locking Price. The Exchange proposes to include proposed Exchange Rule 11.9(a)(2)(C), which would state that, where an order is re-ranked to the Locking Price after a Locking Quotation clears, the System will re-rank and display such orders at the Locking Price in time priority in the following order: (1) ISO with a TIF instruction of Day that establishes a new NBBO at the Locked Price; (2) Limit Orders to which the Hide Not Slide or Routed and Returned Re-Pricing instruction has been applied; (3) Limit Orders to which the Price Adjust instruction has been applied; and (4) orders with a Pegged instruction.[122]                                          Orders not executed and remaining on the EDGX Book after being re-ranked upon clearance of the Locking Quotation will be executed in time priority under proposed Exchange Rule 11.9(a)(2)(A) described above.                

#### 5. Reserve Quantity Priority

The Exchange proposes to amend Exchange Rule 11.9(a)(6) to modify the description of the priority of an order with a Reserve Quantity and to amend certain terms to be consistent with the order type rules under proposed Exchange Rules 11.6 and 11.8.

                    For both the Fixed Replenishment and Random Replenishment instruction, the displayed quantity receives a new time stamp each time it is replenished from the Reserve Quantity. The Reserve Quantity retains the time stamp of its original entry. Current Exchange Rule 11.8(a)(6) discusses the priority of the Reserve Quantity of an order and states that “[a] new time stamp is created both for the refreshed and reserved portion of the order each time it is refreshed from reserve.” The Exchange proposes to amend this description to state that a new time stamp is created only for the displayed quantity of the order each time it is replenished from Reserve Quantity. In addition, as discussed above in Section III.C.1.l, proposed Exchange Rule 11.8(m)(1) states that a new time stamp is created for the portion of the order with a Displayed instruction each time it is replenished from the Reserve Quantity, while the Reserve Quantity retains the time-stamp of its original entry.[123] 

                    The Commission finds that proposed Exchange Rule 11.9 relating to priority is consistent with Section 6(b)(5) of the Act,[124]                                          in that it 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. The proposed rule change codifies the order handling and execution priority of orders on the EDGX Book which in turn provides greater transparency for, and thereby benefit, Members, Users, and the general investing public.                

## IV. Accelerated Approval

                    The Commission finds goods cause, pursuant to Section 19(b)(2) of the Exchange Act,[125]                                          for approving the proposed rule change, as modified by Amendment Nos. 1 and 3 thereto, prior to the 30th day after publication of notice of the filing of Amendment Nos. 1 and 3 in the                     **Federal Register**                    . Amendment No. 1 removes proposed rule text relating to the Single Re-Price and Short Sale Single Re-Price pricing instructions to indicate that the Exchange will no longer offer such functionality, adds language to the Post Only instruction definition to provide that the highest possible rebate paid and the highest possible fee will be used to determine whether the order with a Post Only instruction will execute against orders on the EDGX Book upon arrival, adds rationale to the statutory basis section for suspending the discretion of an order with a Hide Not Slide instruction to execute at the Locking Price when a contra-side order that equals the Locking Price is displayed by the System on the EDGX Book in order to avoid an apparent violation of that contra-side displayed order's priority, and makes a series of non-substantive, corrective changes to the Notice. According to the Exchange, Amendment No. 1 reflects the Exchange's efforts to simplify its proposal and streamline System functionality, thereby benefiting Members, Users and the investing public by making the rules and functionality easier to understand. According to the Exchange, Amendment No. 3 clarifies the operation of the Routed and Returned Re-Pricing instruction, thereby making the rules and functionality easier to understand. Accordingly, the Commission does not believe that Amendments No. 1 and 3 raise any novel regulatory issues and therefore finds that good cause exists to approve the proposal, as modified by Amendment Nos. 1 and 3, on an accelerated basis.

7.                             In Amendment No. 1, the Exchange: (1) Removed the proposed rule text related to Single Re-Price and Short Sale Single Re-Price instructions to indicate that the Exchange will no longer offer such functionality; (2) added language to the Post Only instruction definition to provide that the highest possible rebate paid and the highest possible fee will be used to determine whether an order with a Post Only instruction will execute against orders on the EDGX Book; (3) added rationale to the statutory basis section for suspending the discretion of an order with a Hide Not Slide instruction to execute at the Locking Price when a contra-side order that equals the Locking Price is displayed by the System on the EDGX Book in order to avoid an apparent violation of that contra-side displayed order's priority; and (4) made a series of non-substantive, corrective changes to the Notice. Amendment No. 1 has been placed in the public comment file for SR-EDGX-2014-18 at                         *http://www.sec.gov/​comments/​sr-edgx-2014-18/​edgx201418.shtml*                         (                        *see*                         letter from Christopher Solgan, Regulatory Counsel, DirectEdge, to Secretary, Commission, dated October 15, 2014) and also is available on the Exchange's Web site.

9.                             In Amendment No. 3, the Exchange specified that upon return to the Exchange, an order with the Routed and Returned Re-Pricing instruction will execute against marketable contra-side liquidity displayed on the EDGX Book. If there is no marketable contra-side liquidity displayed on the EDGX book upon return but such Routed and Returned Order would be displayed at a price that would be a Locking or Crossing Quotation, then such order will be displayed at a price that is one Minimum Price Variation lower (higher) than the Locking Price for orders to buy (sell), will be ranked at the mid-point of the NBBO with discretion to execute at the Locking Price. A subsequently arriving contra-side order could suspend the Routed and Returned Order's discretion to execute at the Locking Price. Amendment No. 3 has been placed in the public comment file for SR-EDGX-2014-18 at                         *http://www.sec.gov/​comments/​sr-edgx-2014-18/​edgx201418.shtml*                         (                        *see*                         letter from Christopher Solgan, Regulatory Counsel, DirectEdge, to Secretary, Commission, dated October 17, 2014) and also is available on the Exchange's Web site.

Alternatively set the price of a re-opening at the midpoint of the then prevailing NBBO when the first two-sided quotation is published by the listing exchange following the resumption of trading after a halt, suspension, or pause if no first trade is reported within one second of publication of the first two-sided quotation by the listing exchange; (3) Proposed Rule 11.6(j)(1). Require that an order with a Market Peg instruction that is to be displayed by the System on the EDGX Book include an offset equal to or greater than one Minimum Price Variation; and (4) Proposed Rule 11.6(n)(4). Permit an order with a Post Only instruction to execute against an order resting on the EDGX Book where it is eligible to receive price improvement as described under the proposed rule.

54.                             The “displayed price sliding process” is currently described under Exchange Rule 11.5(c)(4)(A) as follows: “An EDGX Only Order that, at the time of entry, would cross a Protected Quotation will be re-priced to the locking price and ranked at such price in the EDGX Book. An EDGX Only Order that, if at the time of entry, would create a violation of Rule 610(d) of Regulation NMS by locking or crossing a Protected Quotation will be displayed by the System at one minimum price variation (“MPV”) below the current NBO (for bids) or to one MPV above the current NBB (for offers) (collectively, the “displayed price sliding process”). In the event the NBBO changes such that the EDGX Only Order at the original locking price would not lock or cross a Protected Quotation, the order will receive a new timestamp, and will be displayed at the original locking price.”                    
        Back to Citation      

55.                             The “short sale price sliding process” is currently described under Exchange Rule 11.5(c)(4)(B)-(C) as follows: “An EDGX Only Order that, at the time of entry, could not be executed or displayed pursuant to Rule 201 of Regulation SHO will be re-priced by the System to prevent execution or display at or below the current NBB (such entire process called the “short sale price sliding process”). Any EDGX Only order subject to such re-pricing by the System will be re-priced to display at one MPV above the current NBB (“Permitted Price”). Following the initial adjustment provided for in this paragraph (B), the EDGX Only Order will, to reflect declines in the NBB, continue to be re-priced at the lowest Permitted Price down to the order's original limit price, or if a market order, until the order is filled. The order will receive a new timestamp each time it is re-priced. Alternatively, following the initial adjustment provided for in paragraph (B), the EDGX Only Order may, in accordance with the User's instructions, provided that in all cases the display or execution of such lower prices does not violate Rule 201 of Regulation SHO: (i) Be re-priced one additional time to a price that is above the current NBB but equal to the NBB at the time the EDGX Only Order was received and receive a new timestamp; or (ii) not be adjusted further. In the event the NBB changes such that the price of a Non-Displayed Order subject to short sale price sliding would lock or cross the NBB, the Non-Displayed Order will receive a new timestamp, and will be re-priced by the System to a Permitted Price. EDGX Only Orders marked “short exempt” shall not be subject to the short sale price sliding process.”
