Adopted Jan. 22, 2021 (SR-Phlx-2021-04); amended Jun. 27, 2022 (SR-Phlx-2022-28), operative Aug. 10, 2022; amended Nov. 22, 2022 (SR-Phlx-2022-48).

(a) Quotations and quotation sizes may be entered into PSX only by a member organization registered as a PSX Market Maker or other entity approved by the Exchange to function in a market-making capacity. Member organizations seeking to become registered as a PSX Market Maker must comply with the applicable requirements of General 3, Section 1.

(b) A PSX Market Maker may become registered in an issue by entering a registration request via an Exchange approved electronic interface with PSX's systems or by contacting PSX Market Operations. Registration shall become effective on the day the registration request is entered.

(c) A PSX Market Maker's registration in an issue shall be terminated by the Exchange if the market maker fails to enter quotations in the issue within five (5) business days after the market maker's registration in the issue becomes effective.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

A member organization registered as a Market Maker shall engage in a course of dealings for its own account to assist in the maintenance, insofar as reasonably practicable, of fair and orderly markets in accordance with this Rule.
(a) Quotation Requirements and Obligations

(1) Two-Sided Quote Obligation. For each security in which a member organization is registered as a Market Maker, the member organization shall be willing to buy and sell such security for its own account on a continuous basis during regular market hours and shall enter and maintain a two-sided trading interest ("Two-Sided Obligation") that is identified to the Exchange as the interest meeting the obligation and is displayed in PSX's quotation montage at all times. Interest eligible to be considered as part of a Market Maker's Two-Sided Obligation shall have a displayed quotation size of at least one normal unit of trading (or a larger multiple thereof); provided, however, that a Market Maker may augment its Two-Sided Obligation size to display limit orders priced at the same price as the Two-Sided Obligation. Unless otherwise designated, a "normal unit of trading" shall be 100 shares. After an execution against its Two-Sided Obligation, a Market Maker must ensure that additional trading interest exists in PSX to satisfy its Two-Sided Obligation either by immediately entering new interest to comply with this obligation to maintain continuous two-sided quotations or by identifying existing interest on the PSX book that will satisfy this obligation.

(2) Pricing Obligations. For NMS stocks (as defined in Rule 600 under Regulation NMS) a Market Maker shall adhere to the pricing obligations established by this Rule during Regular Trading Hours; provided, however, that such pricing obligations (i) shall not commence during any trading day until after the first regular way transaction on the primary listing market in the security, as reported by the responsible single plan processor, and (ii) shall be suspended during a trading halt, suspension, or pause, and shall not re-commence until after the first regular way transaction on the primary listing market in the security following such halt, suspension, or pause, as reported by the responsible single plan processor.

(A) Bid Quotations. At the time of entry of bid interest satisfying the Two-Sided Obligation, the price of the bid interest shall be not more than the Designated Percentage away from the then current National Best Bid, or if no National Best Bid, not more than the Designated Percentage away from the last reported sale from the responsible single plan processor. In the event that the National Best Bid (or if no National Best Bid, the last reported sale) increases to a level that would cause the bid interest of the Two-Sided Obligation to be more than the Defined Limit away from the National Best Bid (or if no National Best Bid, the last reported sale), or if the bid is executed or cancelled, the Market Maker shall enter new bid interest at a price not more than the Designated Percentage away from the then current National Best Bid (or if no National Best Bid, the last reported sale), or identify to the Exchange current resting interest that satisfies the Two-Sided Obligation.

(B) Offer Quotations. At the time of entry of offer interest satisfying the Two-Sided Obligation, the price of the offer interest shall be not more than the Designated Percentage away from the then current National Best Offer, or if no National Best Offer, not more than the Designated Percentage away from the last reported sale received from the responsible single plan processor. In the event that the National Best Offer (or if no National Best Offer, the last reported sale) decreases to a level that would cause the offer interest of the Two-Sided Obligation to be more than the Defined Limit away from the National Best Offer (or if no National Best Offer, the last reported sale), or if the offer is executed or cancelled, the Market Maker shall enter new offer interest at a price not more than the Designated Percentage away from the then current National Best Offer (or if no National Best Offer, the last reported sale), or identify to the Exchange current resting interest that satisfies the Two-Sided Obligation.

(C) The National Best Bid and Offer shall be determined by the Exchange in accordance with its procedures for determining protected quotations under Rule 600 under Regulation NMS.

(D) For purposes of this Rule, the "Designated Percentage" shall be:

(i) 8% for all Tier 1 NMS Stocks under the LULD Plan;

(ii) 28% for all Tier 2 NMS Stocks under the LULD Plan with a price equal to or greater than $1;

(iii) 30% for all Tier 2 NMS Stocks with a price less than $1, 

except that prior to 9:45 a.m. and between 3:35 p.m. and the close of trading, the Designated Percentage shall be 20% for Tier 1 NMS Stocks under the LULD Plan, 28% for Tier 2 NMS Stocks under the LULD Plan with a price equal to or greater than $1, and 30% for Tier 2 NMS Stocks under the LULD Plan with a price less than $1. The Designated Percentage for rights and warrants shall be 30%.

(E) For purposes of this Rule, the "Defined Limit" shall be 9.5% for Tier 1 NMS Stocks under the LULD Plan, 29.5% for all Tier 2 NMS Stocks under the LULD Plan with a price equal to or greater than $1, and 31.5% for all Tier 2 NMS Stocks under the LULD Plan with a price less than $1, except that prior to 9:45 a.m. and between 3:35 p.m. and the close of trading, the Defined Limit shall be 21.5% for all Tier 1 NMS Stocks under the LULD Plan, 29.5% for all Tier 2 NMS Stocks under the LULD Plan with a price equal to or greater than $1, and 31.5% for all Tier 2 NMS Stocks under the LULD Plan with a price less than $1. The Defined Limit for rights and warrants shall be 31.5%. 

(F) Nothing in this Rule shall preclude a Market Marker from quoting at price levels that are closer to the National Best Bid and Offer than the levels required by this Rule.

(G) The minimum quotation increment for quotations of $1.00 or above in all System Securities shall be $0.01. The minimum quotation increment in the System for quotations below $1.00 in System Securities shall be $0.0001.

(H) The individual Market Participant Identifier ("MPID") assigned to a member organization to meet its Two-Sided Obligation pursuant to subparagraph (a)(1) of this Rule, or Equity 2, Section 14, shall be referred to as the member organization's "Primary MPID." Market Makers and ECNs may request the use of additional MPIDs that shall be referred to as "Supplemental MPIDs." A Market Maker may request the use of Supplemental MPIDs for displaying Attributable Quotes/Orders in the PSX quotation montage for any security in which it is registered and meets the obligations set forth in subparagraph (1) of this rule. An ECN may request the use of Supplemental MPIDs for displaying Attributable Quotes/Orders in the PSX quotation montage for any security in which it meets the obligations set forth in Equity 2, Section 14. A Market Maker or ECN that ceases to meet the obligations appurtenant to its Primary MPID in any security shall not be permitted to use a Supplemental MPID for any purpose in that security.

(I) Market Makers and ECNs that are permitted the use of Supplemental MPIDs for displaying Attributable Quotes/Orders pursuant to subparagraph (2) of this rule are subject to the same rules applicable to their first quotation, with two exceptions: (a) the continuous two-sided quote requirement and excused withdrawal procedures described in subparagraph (1) above do not apply to Market Makers' Supplemental MPIDs; and (b) Supplemental MPIDs may not be used by Market Makers to enter stabilizing bids pursuant to Equity 2, Section 6.

(b) Firm Orders and Quotations. All quotations and orders to buy and sell entered into the System by PSX Participants are firm and automatically executable for their displayed and non-displayed size in the System.

(c) Impaired Ability to Enter or Update Quotations
In the event that a PSX Market Maker's ability to enter or update quotations is impaired, the market maker shall immediately contact PSX Market Operations to request the withdrawal of its quotations.
In the event that a PSX Market Maker's ability to enter or update quotations is impaired and the market maker elects to remain in PSX, the PSX Market Maker shall execute an offer to buy or sell received from another member organization at its quotations as disseminated through PSX.

(d) Locked and Crossed Markets.

(1) Locked and Cross Markets within the System. Any orders that are entered into the System that would lock or cross another order in the System will be executed by the System. This processing, set forth in Equity 4, Rule 3307, ensures that no locked or crossed markets can exist within the System and that price improvement is allocated fairly.

(2) Inter-market Locked and Crossed Markets. The provisions of this subsection (d)(2) apply to the trading of securities governed by Regulation NMS.

(A) Definitions. For purposes of this Rule, the following definitions shall apply:

(i) The terms automated quotation, effective national market system plan, intermarket sweep order, manual quotation, NMS stock, protected quotation, regular trading hours, and trading center shall have the meanings set forth in rule 600(b) of Regulation NMS under the Securities Exchange Act of 1934.

(ii) The term crossing quotation shall mean the display of a bid for an NMS stock during regular trading hours at a price that is higher than the price of an offer for such NMS stock previously disseminated pursuant to an effective national market system plan, or the display of an offer for an NMS stock during regular trading hours at a price that is lower than the price of a bid for such NMS stock previously disseminated pursuant to an effective national market system plan.

(iii) The term locking quotation shall mean the display of a bid for an NMS stock during regular trading hours at a price that equals the price of an offer for such NMS stock previously disseminated pursuant to an effective national market system plan, or the display of an offer for an NMS stock during regular trading hours at a price that equals the price of a bid for such NMS stock previously disseminated pursuant to an effective national market system plan.

(B) Prohibition. Except for quotations that fall within the provisions of paragraph (D) of this Rule, Exchange member organizations shall reasonably avoid displaying, and shall not engage in a pattern or practice of displaying any quotations that lock or cross a protected quotation, and any manual quotations that lock or cross a quotation previously disseminated pursuant to an effective national market system plan.

(C) Manual quotations. If an Exchange member organization displays a manual quotation that locks or crosses a quotation previously disseminated pursuant to an effective national market system plan, such member organization shall promptly either withdraw the manual quotation or route an intermarket sweep order to execute against the full displayed size of the locked or crossed quotation.

(D) Exceptions.

(i) The locking or crossing quotation was displayed at a time when the trading center displaying the locked or crossed quotation was experiencing a failure, material delay, or malfunction of its systems or equipment.

(ii) The locking or crossing quotation was displayed at a time when a protected bid was higher than a protected offer in the NMS stock.

(iii) The locking or crossing quotation was an automated quotation, and the Exchange member organization displaying such automated quotation simultaneously routed an intermarket sweep order to execute against the full displayed size of any locked or crossed protected quotation.

(iv) The locking or crossing quotation was a manual quotation that locked or crossed another manual quotation, and the Exchange member organization displaying the locking or crossing manual quotation simultaneously routed an intermarket sweep order to execute against the full displayed size of the locked or crossed manual quotation.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) PSX Market Maker Obligation/Identifier
A PSX Market Maker that intends to stabilize the price of a security that is a subject or reference security under SEC Rule 101 shall submit a request to the Exchange's MarketWatch Department for the entry of a one-sided bid that is identified on the Exchange as a stabilizing bid in compliance with the standards set forth in this Rule and SEC Rules 101 and 104.

(b) Eligibility
Only one PSX Market Maker in a security may enter a stabilizing bid.

(c) Limitations on Stabilizing Bids

(1) A stabilizing bid shall not be entered in PSX unless at least one other PSX Market Maker in addition to the market maker entering the stabilizing bid is registered as a PSX Market Maker in the security and entering quotations that are considered an independent bid under SEC Rule 104.

(2) A stabilizing bid must be available for all freely tradable outstanding securities of the same class being offered.

(d) Submission of Request to the Exchange

(1) A PSX Market Maker that wishes to enter a stabilizing bid shall submit a request to the Exchange's MarketWatch Department for entry in PSX of a one-sided bid identified as a stabilizing bid. The PSX Market Maker shall confirm its request in writing no later than the close of business the day the stabilizing bid is entered by submitting an Underwriting Activity Report to the Exchange's MarketWatch Department that includes the information required by subparagraph (d)(2).

(2) In lieu of submitting the Underwriting Activity Report as set forth in subparagraph (d)(1), the market maker may provide written confirmation to MarketWatch that shall include:

(A) the identity of the security and its symbol;

(B) the contemplated effective date of the offering and the date when the offering will be priced;

(C) the date and time that an identifier should be included on the Exchange; and

(D) a copy of the cover page of the preliminary or final prospectus or similar offering document, unless the Exchange determines otherwise.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

A PSX Participant shall make such reports to the Exchange as may be prescribed from time to time by the Exchange.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

The System operates from 8:00 a.m. to 5:00 p.m. Eastern Time on each business day, unless modified by the Exchange. A PSX Market Maker shall be open for business as of 9:30 a.m. Eastern Time and shall close no earlier than 4:00 p.m. Eastern Time. A PSX Market Maker may voluntarily open for business prior to 9:30 a.m. and remain open for business later than 4:00 p.m. Eastern Time. PSX Market Makers whose quotes are open prior to 9:30 a.m. Eastern Time or after 4:00 p.m. Eastern Time shall be obligated to comply, while their quotes are open, with all Equity Rules that are not by their express terms, or by an official interpretation of the Exchange, inapplicable to any part of the 8:00 a.m. to 9:30 a.m. or 4:00 p.m. to 5:00 p.m. Eastern Time period.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) All transactions through the facilities of PSX shall be cleared and settled through a registered clearing agency using a continuous net settlement system. This requirement may be satisfied by direct participation, use of direct clearing services, by entry into a correspondent clearing arrangement with another member organization that clears trades through such a clearing agency, or by use of the services of CDS Clearing and Depository Services, Inc. in its capacity as a member of such a clearing agency.

(b) Notwithstanding paragraph (a), transactions may be settled "ex-clearing" provided that both parties to the transaction agree.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) Except as provided in paragraph (b) of this Rule, a market maker that wishes to withdraw quotations in a security shall contact the Exchange's MarketWatch Department to obtain excused withdrawal status prior to withdrawing its quotations. Withdrawals of quotations shall be granted by MarketWatch only upon satisfying one of the conditions specified in this Rule.

(b) A PSX Market Maker that wishes to obtain excused withdrawal status based on a market maker's systemic equipment problems, such as defects in a PSX Market Maker's software or hardware systems or connectivity problems associated with the circuits connecting PSX systems with the PSX Market Maker's systems, shall contact Exchange Market Operations. Exchange Market Operations may grant excused withdrawal status based on systemic equipment problems for up to five (5) business days, unless extended by Exchange Market Operations.

(c) A PSX Market Maker that wishes to withdraw quotations shall contact the Exchange's MarketWatch Department to obtain excused withdrawal status prior to withdrawing its quotations. Excused withdrawal status based on illness, vacations or physical circumstances beyond the PSX Market Maker's control may be granted for up to five (5) business days, unless extended by MarketWatch. Excused withdrawal status based on investment activity or advice of legal counsel, accompanied by a representation that the condition necessitating the withdrawal of quotations is not permanent in nature, may, upon written request, be granted for not more than sixty (60) days. The withdrawal of quotations because of pending news, a sudden influx of orders or price changes, or to effect transactions with competitors shall not normally constitute acceptable reasons for granting excused withdrawal status, unless the Exchange has initiated a trading halt for market makers in the security, pursuant to Equity 4, Rule 3100.

(d) Excused withdrawal status may be granted to a PSX Market Maker that fails to maintain a clearing arrangement with a registered clearing agency or with a member of such an agency and is withdrawn from participation in the trade reporting service of PSX, thereby terminating its registration as a PSX Market Maker; provided, however, that if the Exchange finds that the PSX Market Maker's failure to maintain a clearing arrangement is voluntary, the withdrawal of quotations will be considered voluntary and unexcused pursuant to Equity 2, Section 11 and Equity 4 governing PSX. PSX Market Makers that fail to maintain a clearing relationship will have their PSX system status set to "suspend" and be thereby prevented from entering, or executing against, any quotes/orders in the system.

(e) Excused withdrawal status may be granted to a PSX Market Maker that is a distribution participant (or, in the case of excused withdrawal status, an affiliated purchaser) in order to comply with SEC Rule 101 or 104 under the Act on the following conditions:

(1) A member organization acting as a manager (or in a similar capacity) of a distribution of a security that is a subject security or reference security under SEC Rule 101 and any member organization that is a distribution participant or an affiliated purchaser in such a distribution that does not have a manager shall provide written notice to the Exchange's MarketWatch Department and the Market Regulation Department of FINRA no later than the business day prior to the first entire trading session of the one-day or five-day restricted period under SEC Rule 101, unless later notification is necessary under the specific circumstances.

(A) The notice required by subparagraph (e)(1) of this Rule shall be provided by submitting a completed Underwriting Activity Report that includes a request on behalf of each PSX Market Maker that is a distribution participant or an affiliated purchaser to withdraw the PSX Market Maker's quotations and includes the contemplated date and time of the commencement of the restricted period.

(B) The managing underwriter shall advise each PSX Market Maker that it has been identified as a distribution participant or an affiliated purchaser to MarketWatch and that its quotations will be automatically withdrawn, unless a market maker that is a distribution participant (or an affiliated purchaser of a distribution participant) notifies MarketWatch as required by subparagraph (e)(2), below.

(2) A PSX Market Maker that has been identified to MarketWatch as a distribution participant (or an affiliated purchaser of a distribution participant) shall promptly notify MarketWatch and the manager of its intention not to participate in the prospective distribution in order to avoid having its quotations withdrawn.

(3) If a PSX Market Maker that is a distribution participant withdraws its quotations in order to comply with any provision of SEC Regulation M and promptly notifies MarketWatch of its action, the withdrawal shall be deemed an excused withdrawal. Nothing in this subparagraph shall prohibit the Exchange from taking such action as is necessary under the circumstances against a member organization and its associated persons for failure to contact MarketWatch to obtain an excused withdrawal as required by subparagraphs (a) and (e) of this Rule.

(4) A member organization acting as a manager (or in a similar capacity of a distribution subject to subparagraph (e)(1)) of this Rule shall submit a request to MarketWatch and the Market Regulation Department of FINRA to rescind the excused withdrawal status of distribution participants and affiliated purchasers, which request shall include the date and time of the pricing of the offering, the offering price, and the time the offering terminated, and, if not in writing, shall be confirmed in writing no later than the close of business the day the offering terminates. The request by this subparagraph may be submitted on the Underwriting Activity Report

(f) The Exchange Review Council shall have jurisdiction over proceedings brought by PSX Market Makers seeking review of the denial of an excused withdrawal pursuant to this Equity 2, Section 10, or the conditions imposed on their reentry.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) A market maker may voluntarily terminate its registration in a security by withdrawing its two-sided quotation from PSX. A PSX Market Maker that voluntarily terminates its registration in a security may not re-register as a market maker for one (1) business day. Withdrawal from participation as a PSX Market Maker shall constitute termination of registration as a market maker in that security for purposes of this Rule; provided, however, that a PSX Market Maker that fails to maintain a clearing arrangement with a registered clearing agency or with a member of such an agency and is withdrawn from participation in the PSX and thereby terminates its registration as a PSX Market Maker may register as a market maker at any time after a clearing arrangement has been reestablished unless the Exchange finds that the PSX Market Maker's failure to maintain a clearing arrangement is voluntary, in which case the withdrawal of quotations will be considered voluntary and unexcused.

(b) Notwithstanding the above, a PSX Market Maker that accidentally withdraws as a PSX Market Maker may be reinstated if:

(1) the PSX Market Maker notified the Exchange's MarketWatch Department of the accidental withdrawal as soon as practicable under the circumstances, but within at least one hour of such withdrawal, and immediately thereafter provided written notification of the withdrawal and reinstatement request;

(2) it is clear that the withdrawal was inadvertent and the market maker was not attempting to avoid its market making obligations; and

(3) the PSX Market Maker's firm would not exceed the following reinstatement limitations:

(A) for firms that simultaneously made markets in less than 250 stocks during the previous calendar year, the firm can receive no more than two (2) reinstatements per year;

(B) for firms that simultaneously made markets in 250 or more but less than 500 stocks during the previous calendar year, the firm can receive no more than three (3) reinstatements per year; and

(C) for firms that simultaneously made markets in 500 or more stocks during the previous calendar year, the firm can receive no more than six (6) reinstatements per year.

(c) Factors that the Exchange will consider in granting a reinstatement under paragraph (b) of this rule include, but are not limited to:

(1) the number of accidental withdrawals by the PSX Market Maker in the past, as compared with PSX Market Makers making markets in a comparable number of stocks;

(2) the similarity between the symbol of the stock that the PSX Market Maker intended to withdraw from and the symbol of the stock that the PSX Market Maker actually withdrew from;

(3) market conditions at the time of the withdrawal;

(4) whether, given the market conditions at the time of the withdrawal, the withdrawal served to reduce the exposure of the PSX Market Maker's position in the security at the time of the withdrawal to market risk; and

(5) the timeliness with which the PSX Market Maker notified MarketWatch of the error.

(d) For purposes of paragraph (a) of this Rule, a market maker shall not be deemed to have voluntarily terminated its registration in a security by voluntarily withdrawing its two-sided quotation from PSX if the PSX Market Maker's two-sided quotation in the subject security is withdrawn by the Exchange's systems due to issuer corporate action related to a dividend, payment or distribution, or due to a trading halt, and one of the following conditions is satisfied:

(1) the PSX Market Maker enters a new two-sided quotation prior to the close of the regular market session on the same day when the Exchange's systems withdrew such a quotation;

(2) the PSX Market Maker enters a new two-sided quotation on the day when trading resumes following a trading halt, or, if the resumption of trading occurs when the market is not in regular session, the PSX Market Maker enters a new two-sided quotation prior to the opening of the next regular market session; or

(3) upon request from the market maker, MarketWatch authorizes the market maker to enter a new two-sided quotation, provided that MarketWatch receives the market maker's request prior to the close of the regular market session on the next regular trading day after the day on which the market maker became eligible to re-enter a quotation pursuant to subparagraph (d)(1) or (d)(2) hereof and determines that the market maker was not attempting to avoid its market making obligations by failing to re-enter such a quotation earlier.

(e) The Exchange Review Council shall have jurisdiction over proceedings brought by market makers seeking review of their denial of a reinstatement pursuant to paragraphs (b) or (d) of this Rule.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

The Exchange may, pursuant to the procedures set forth in Disciplinary Rules of the Exchange (Rules 960.1 through 960.12), suspend, condition, limit, prohibit or terminate the authority of an PSX Participant to enter quotations or orders in one or more authorized securities for violations of applicable requirements or prohibitions.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

The Exchange may, upon notice, terminate PSX service in the event that a PSX Participant fails to qualify under specified standards of eligibility or fails to pay promptly for services rendered by PSX.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) The Exchange may provide a means to permit alternative trading systems ("ATSs"), as such term is defined in Regulation ATS, and electronic communications networks ("ECNs"), as such term is defined in SEC rule 600,

(1) to comply with SEC rule 301(b)(3);

(2) to comply with the terms of the ECN display alternatives provided for in SEC rule 602(b)(5)(ii)(A) and (B) ("ECN display alternatives"); or

(3) to provide orders to PSX voluntarily.

In providing any such means, the Exchange shall establish a mechanism that permits the ATS or ECN to display the best prices and sizes of orders entered into the ATS or ECN by subscribers of the ATS or ECN, if the ECN or ATS so chooses or is required by SEC rule 301(b)(3) to display a subscriber's order in PSX, and allows any Exchange member organization the electronic ability to effect a transaction with such priced orders that is equivalent to the ability to effect a transaction with other orders displayed by PSX. Orders displayed by ECNs or ATSs shall be displayed without attribution.

(b) An ATS or ECN that seeks to utilize PSX to comply with SEC rule 301(b)(3) or the ECN display alternatives, or to provide orders to the Exchange voluntarily shall:

(1) demonstrate to the Exchange that it is in compliance with Regulation ATS or that it qualifies as an ECN meeting the definition in the SEC rule 600;

(2) be registered as a member organization;

(3) enter into and comply with the terms of applicable agreements with the Exchange;

(4) agree to provide for the Exchange's dissemination in the data made available to vendors the prices and sizes of subscriber orders of the ATS or ECN, if the ATS or ECN so chooses or is required by SEC rule 301(b)(3) to display a subscriber's order in PSX, at the highest buy price and the lowest sell price for each security entered in and widely disseminated by the ATS or ECN; and prior to entering such prices and sizes, register with the Exchange as an ATS or ECN; and

(5) provide an automatic execution of any quote or order entered into the System by the ATS or ECN.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

A PSX Market Maker that intends to impose a penalty bid on syndicate members may request that its quotation be identified as a penalty bid on the Exchange pursuant to paragraph (c) below.

(b) The notice required by paragraph (a) shall include:

(1) the identity of the security and its symbol; 

(2) the date the PSX Market Maker is intending to impose the penalty bid and/or conduct syndicate covering transactions.

(c) Notwithstanding paragraph (a), a PSX Market Maker may request that its quotation be identified as a penalty bid on the Exchange by providing notice to the Exchange's MarketWatch Department, which notice shall include the date and time that the penalty bid identifier should be entered on the Exchange and, if not in writing, shall be confirmed in writing no later than the close of business the day the penalty bid identifier is entered on the Exchange.

(d) The written notice required by this Rule may be submitted on the Underwriting Activity Report.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) An Exchange member organization operating in or participating in PSX shall provide information orally, in writing, or electronically (if such information is, or is required to be, maintained in electronic form) to Exchange staff when staff makes an oral, written, or electronically communicated request for information relating to a specific Exchange Rule, SEC rule, or provision of a joint industry plan (e.g., UTP, CTA, and CQA) (as promulgated and amended from time-to-time) that the Exchange is responsible for administering or to other duties and/or obligations imposed on the Exchange; this shall include, but not be limited to, information relating to:

(A) a locked or crossed market; or

(B) trading activity, rumors, or information that a member or member organization may possess that may assist in determining whether there is a basis to initiate a trading halt, pursuant to Equity 4, Rule 3100; or

(b) A failure to comply in a timely, truthful, and/or complete manner with a request for information made pursuant to this rule may be deemed conduct inconsistent with just and equitable principles of trade.

Adopted Jan. 22, 2021 (SR-Phlx-2021-04).

(a) Except as provided for in paragraph (b) below, the Exchange and its affiliates shall not be liable for any losses, damages, or other claims arising out of PSX or its use. Any losses, damages, or other claims, related to a failure of PSX to deliver, transmit, execute, compare, submit for clearance and settlement, adjust, retain priority for, or otherwise correctly process an order, Quote/Order, message, or other data entered into, or created by, PSX shall be absorbed by the member organization, or the member organization sponsoring the customer, that entered the order, Quote/Order, message, or other data into PSX.

(b) The Exchange, subject to the express limits set forth below, may compensate users of PSX for losses directly resulting from the System's actual failure to correctly process an order, Quote/Order, message, or other data, provided PSX has acknowledged receipt of the order, Quote/Order, message, or data.

(1) For the aggregate of all claims made by all market participants related to the use of PSX during a single calendar month, the Exchange's liability shall not exceed the larger of $500,000, or the amount of the recovery obtained by the Exchange under any applicable insurance policy.

(2) In the event all of the claims arising out of the use of PSX cannot be fully satisfied because in the aggregate they exceed the maximum amount of liability provided for in this Rule, then the maximum amount will be proportionally allocated among all such claims arising during a single calendar month.

(3) All claims for compensation pursuant to this Rule shall be in writing and must be submitted no later than 12:00 p.m. ET on the next business day following the day on which the use of PSX gave rise to such claims. Nothing in this rule shall obligate the Exchange to seek recovery under any applicable insurance policy.

No member organization may accept an order from a customer for execution in the Pre-Market Session or Post-Market Session without disclosing to such customer that extended hours trading involves material trading risks, including the possibility of lower liquidity, high volatility, changing prices, unlinked markets, an exaggerated effect from news announcements, wider spreads and any other relevant risk. The absence of an updated underlying index value or intraday indicative value is an additional trading risk in extended hours for Derivative Securities Products.

The disclosures required pursuant to this Rule may take the following form or such other form as provides substantially similar information:

(1) Risk of Lower Liquidity. Liquidity refers to the ability of market participants to buy and sell securities. Generally, the more orders that are available in a market, the greater the liquidity. Liquidity is important because with greater liquidity it is easier for investors to buy or sell securities, and as a result, investors are more likely to pay or receive a competitive price for securities purchased or sold. There may be lower liquidity in extended hours trading as compared to regular market hours. As a result, your order may only be partially executed, or not at all.

(2) Risk of Higher Volatility. Volatility refers to the changes in price that securities undergo when trading. Generally, the higher the volatility of a security, the greater its price swings. There may be greater volatility in extended hours trading than in regular market hours. As a result, your order may only be partially executed, or not at all, or you may receive an inferior price in extended hours trading than you would during regular market hours.

(3) Risk of Changing Prices. The prices of securities traded in extended hours trading may not reflect the prices either at the end of regular market hours, or upon the opening of the next morning. As a result, you may receive an inferior price in extended hours trading than you would during regular market hours.

(4) Risk of Unlinked Markets. Depending on the extended hours trading system or the time of day, the prices displayed on a particular extended hours system may not reflect the prices in other concurrently operating extended hours trading systems dealing in the same securities. Accordingly, you may receive an inferior price in one extended hours trading system than you would in another extended hours trading system.

(5) Risk of News Announcements. Normally, issuers make news announcements that may affect the price of their securities after regular market hours. Similarly, important financial information is frequently announced outside of regular market hours. In extended hours trading, these announcements may occur during trading, and if combined with lower liquidity and higher volatility, may cause an exaggerated and unsustainable effect on the price of a security.

(6) Risk of Wider Spreads. The spread refers to the difference in price between what you can buy a security for and what you can sell it for. Lower liquidity and higher volatility in extended hours trading may result in wider than normal spreads for a particular security.

(7) Risk of Lack of Calculation or Dissemination of Underlying Index Value or Intraday Indicative Value ("IIV"). For certain Derivative Securities Products, an updated underlying index value or IIV may not be calculated or publicly disseminated in extended trading hours. Since the underlying index value and IIV are not calculated or widely disseminated during the pre-market and post-market sessions an investor who is unable to calculate implied values for certain Derivative Securities Products in those sessions may be at a disadvantage to market professionals.
