In whom does FINRA Rule 11892 vest the authority to review an over-the-counter transaction in an exchange-listed security?

The Uniform Practice Code Committee, sitting as a panel of at least three of its members

An Executive Vice President of Market Regulation or Transparency Services, or an officer they designate

The primary listing market for the security, acting through its own regulatory staff

Any FINRA staff member of the department that received the trade report in question

On what grounds may a FINRA officer declare an over-the-counter transaction in an exchange-listed security null and void?

Only that the transaction is clearly erroneous within the meaning the general provision gives that term

That either party to the transaction has requested nullification of it in writing within the period the rule permits

That it is clearly erroneous, or that nullification is necessary for a fair and orderly market and investor protection

That the transaction was executed outside the security's applicable Price Bands

Within what time must a FINRA officer act on a transaction under review?

Generally within thirty minutes of becoming aware, and in extraordinary circumstances by the start of trading the next day

Before the transaction under review reaches its settlement date, with a further extension where the parties agree to one

Within one business day of the officer becoming aware of the transaction, in all circumstances whatever

Within thirty minutes of execution, regardless of when the officer became aware

A transaction in an exchange-listed security is executed during Normal Market Hours. What is its position as regards clearly erroneous review?

It is reviewable on the same basis as a transaction executed outside those hours

Review is generally unavailable unless it falls within one of three enumerated categories

It is reviewable only where the primary listing market has itself broken a related trade

It is not reviewable at all, the framework applying outside Normal Market Hours only

One category of reviewable transaction covers securities where the Price Bands were unavailable, where a member's systems issue put a trade outside them, or where a halt had been declared. What do those three circumstances have in common?

Each requires the member to have certified the cause before review may proceed

Each involves a transaction that was executed away from the security's own primary listing market

In each the Price Band machinery was absent, defeated or suspended when the trade occurred

Each arises only in securities that the LULD Plan does not cover at all

The Numerical Guidelines set percentage thresholds by reference to a security's price level. How do the thresholds vary with that level?

They rise with the price, higher-priced securities being permitted wider deviations

They vary by trading volume rather than by price, thinly traded issues being allowed more

They are the same at every price level, varying only inside and outside market hours

They fall as the price rises, higher-priced securities being allowed narrower deviations

A transaction is reviewed in a two-times leveraged exchange-traded product. How is the applicable Numerical Guideline determined?

By multiplying the otherwise applicable guideline by the product's leverage multiplier

By halving the otherwise applicable guideline, the product being twice as volatile

By the guideline for the underlying index, applied without adjustment

By the guideline for the price tier the product's own share price falls into, unadjusted

A Multi-Stock Event involves twenty or more securities. What does FINRA do?

Reviews each affected transaction individually against its own separately determined Reference Price and the Numerical Guideline for its tier

Sets a Reference Price and review period in coordination with other regulators, and nullifies everything thirty per cent or more away

Refers the whole of the event to the Uniform Practice Code Committee, which then determines every affected transaction in the first instance

Declines to act, the event being one for the primary listing markets to resolve

A FINRA officer may consider a list of additional factors — system malfunctions, volatility, news releases, corporate actions and others. When are those factors NOT available?

Where the security is covered by the LULD Plan's Price Bands

Where the transaction was executed outside Normal Market Hours

Where the member has certified a technological or systems issue

What is the default Reference Price against which a transaction's deviation is measured?

The security's closing price on the previous trading day

The volume-weighted average price over the trading session to that point

The midpoint of the national best bid and offer at the time of execution

On what basis may a series of transactions across one or more trading days be treated as a single Event?

That they together represent a substantial proportion of the security's volume

That they were all executed by the same member within a single defined period of time

That they all occurred while the security's Price Bands were unavailable

Two categories of transaction lie outside the multi-day Event power however severe the valuation error. Which?

Transactions executed outside Normal Market Hours, and transactions in leveraged products

Transactions that have reached settlement date, and transactions resulting from an initial public offering

Transactions carried out between two members, and transactions that were reported through a Trade Reporting Facility

Transactions in securities covered by the LULD Plan, and transactions during a trading halt

A disruption in a regulatory communication facility means trades continue after the primary listing market has declared a halt. What happens to them?

They are reviewed individually against the Numerical Guidelines for the security's price tier

They stand, since the halt binds only the market that declared it until notice of it reaches other venues

They are declared null and void, as are trades before the official end of a halt lifted in error

They stand unless a member requests review within thirty minutes of the halt ending

An exchange breaks a trade in a security at a particular price and time, and a related over-the-counter trade in that security was reported to a FINRA system. What is FINRA's general policy?

To review the reported trade quite independently, the exchange's own determination having no bearing on it

To refer the matter to the Uniform Practice Code Committee for a consistent ruling

To break the reported trade only where the member that reported it consents

To follow the exchange's determination, and likewise to leave a trade unbroken where the exchange did

A member asks for review of a transaction that fell outside the applicable Price Bands, saying its own systems caused it. What must the member provide?

A certification, in the prescribed manner and form, that a bona fide technological issue caused it

Evidence that the counterparty was aware the price lay outside the Price Bands

An independent auditor's report on the systems failure that is said to have produced the transaction

A written undertaking to remediate the systems issue within a specified period

FINRA Rule 11892 carries one of the most extensively amended histories in the 11000 Uniform Practice Code, its effective dates spanning three decades. What does that reflect?

A provision repeatedly found defective and rewritten from scratch each time

Repeated adjustment as market structure changed around the framework

The transfer of the rule between three predecessor rulebooks in succession

A rule extended in stages to security types it did not originally cover

During Normal Market Hours, trades in which securities are measured for clearly erroneous status against the Numerical Guidelines table?

Securities in which a member's own systems issue caused a trade to print outside the Price Bands

NMS Stocks that are subject to the LULD Plan, whenever their Price Bands were operating normally

NMS Stocks that are not subject to the LULD Plan, and so trade without Price Bands

Securities whose Reference Price is above $50.00, whichever trading plan happens to cover them

A trade executed during Normal Market Hours is reviewed under the Percentage Parameter test. In which direction must its price have departed from the Reference Price for the trade to be clearly erroneous?

Above it for a buy or a sell alike, an overpayment being the only error the test looks for

Below it for a buy and above it for a sell, by at least the applicable Percentage Parameter

In either direction for a buy and a sell alike, by at least the applicable Percentage Parameter

Above it for a buy and below it for a sell, by at least the applicable Percentage Parameter

The Numerical Guidelines table sets its percentage figures, each a deviation from the Reference Price, by Reference Price tier and by whether a trade fell during or outside Normal Market Hours. Tier for tier, how does the figure for trades outside those hours compare with the figure for eligible trades during them?

The figure outside Normal Market Hours is double the in-hours figure, at every Reference Price tier

The figure outside Normal Market Hours is half the in-hours figure at every tier, fewer participants trading then

The figure outside Normal Market Hours is five percentage points higher, at every Reference Price tier

The figure outside Normal Market Hours is ten percentage points higher, at every Reference Price tier

Trades in twelve different securities are executed within the same five minutes, forming a Multi-Stock Event. What Numerical Guideline applies to those trades?

A flat 20 per cent from each trade's Reference Price, whether inside or outside Normal Market Hours

A flat 10 per cent from each trade's Reference Price, whether inside or outside Normal Market Hours

A flat 5 per cent from each trade's Reference Price, whether inside or outside Normal Market Hours

Each security's own single-stock guideline for its Reference Price tier and session, applied unchanged

A Multi-Stock Event involving twenty or more securities is triggered by trades executed within a five-minute window. How does the review period used to nullify trades in such an event relate to that window?

It ends at the close of the session in which the event began, however long that session runs

It is confined to the five-minute window, so trades printed after it must be reviewed one at a time

It may run beyond the five-minute window, so trades printed after the window can still be reached

It is limited to the minute in which the heaviest trading occurred, the other trades standing

What reason does the rule give for subjecting Multi-Stock Events that involve twenty or more securities to special procedures?

Trades across that many securities are each too small to justify being reviewed one at a time

Events of that size are presumed to result from fraud, which ordinary review is not built to handle

The primary listing markets cannot break trades across that many securities on their own authority

The number of affected trades may be so great that immediate finality becomes necessary

A security resumes trading after a Trading Pause without an auction, and trades printed on resumption are put up for review. The ordinary Reference Price is found to be erroneous. What does the rule make the Reference Price instead?

The security's official closing price on the trading day before the Pause occurred, adjusted for any intervening corporate action

The first trade printed once trading resumed, the Pause being treated as having reset the market's price

The midpoint of the best quotations displayed at the moment trading resumed

A security that traded over the counter up-lists to a national securities exchange, and its Reference Price on the first day is found to be erroneous. What does the rule name as a source FINRA may consider in setting a substitute Reference Price?

The average of the security's over-the-counter closing prices across the preceding twenty trading days

The prior day's final closing report from FINRA's Trade Dissemination Service

The best bid displayed for the security on an interdealer quotation system at the prior close

The opening quotation the listing exchange disseminated for the security that first morning

A FINRA officer is treating a run of trades in one security, spread over several trading days, as a single multi-day Event. By when must the officer declare the Event's trades null and void?

By the close of the fifth trading day after the Event's first trade, so that other regulators can be consulted

By the start of trading on the day after the Event's first trade, the later trades being swept into that declaration

By the start of trading the day after the Event's last trade, or before resumption if trading is halted before correction

At no fixed time, since the Event may still be running and the power carries no deadline of its own

A malfunction in transmitting a regulatory halt lets trades continue after the primary listing market has declared the halt. One such trade printed half of one per cent away from its Reference Price of $60.00. Does the small size of that deviation affect how the trade is treated?

No — trades during a halt stand whatever their price, the halt binding only the market that declared it

Yes — only trades beyond the applicable Numerical Guideline are voided, so this one is left standing

Yes — the trade is instead weighed against the additional factors, its deviation being too small for the guideline

No — trades during the halt are dealt with without regard to the Numerical Guidelines or Percentage Parameters

A national securities exchange breaks a trade in an exchange-listed security. Is FINRA bound to break the corresponding over-the-counter trade reported to its system?

No — it generally follows the exchange, but where that is consistent with market integrity and investor protection

Yes — it must break every corresponding trade the exchange's determination covers, however its own review would come out

Yes, where the exchange is the security's primary listing market; with any other exchange it reviews the trade afresh

No — it reviews the reported trade afresh, the exchange's determination carrying no weight in its decision

An exchange breaks trades in a security that printed around $41.00 at 10:02 a.m. Over the counter, reported to a FINRA system, the security also printed at $41.05 at 10:02 a.m. and at $38.10 at 2:40 p.m. To which of those trades does FINRA's coordination policy generally extend?

Both trades, the policy reaching every over-the-counter trade in that security made on the same day

The $41.05 trade at 10:02 a.m., it being at or near the relevant price and time

The $38.10 trade at 2:40 p.m., the policy reaching trades printed after the exchange announced its break

Neither trade, the policy reaching only trades that were themselves executed on the exchange

A member seeking review of a trade that its own systems issue pushed outside the Price Bands must certify that the issue was a bona fide technological or systems one. What use of this review pathway is the certification requirement meant to prevent?

Using it for trades that the member had already reported late to a FINRA trade reporting facility

Using it to reverse trades that FINRA's own facilities, rather than the member's systems, had mispriced

Using it to unwind executions that were merely unfavourable rather than caused by a genuine malfunction

Using it to shift a loss onto a counterparty that was never notified that a review was under way

Most of FINRA Rule 11892's amendments fall between 2010 and 2022. What development do they trace?

The growth of alternative trading systems and the rules adopted to register them as exchanges

The shortening of the standard settlement cycle, first from three business days to two

The move from fractional to decimal pricing and the narrower quoted spreads that followed it

The phased implementation and refinement of the Limit Up-Limit Down Plan and its Price Bands

FINRA Rule 11892: Clearly Erroneous Exchange-Listed Trades

What Does FINRA Rule 11892 Require for Clearly Erroneous Transactions in Exchange-Listed Securities?

FINRA Rule 11892 establishes the detailed procedural and substantive framework for FINRA's review of over-the-counter transactions in exchange-listed securities for clearly erroneous status — among the most extensively and continuously amended provisions in the 11000 Uniform Practice Code, reflecting its deep integration with the post-2010 market-structure infrastructure built around the Limit Up-Limit Down (LULD) Plan adopted under Regulation NMS.

The rule operates through five lettered paragraphs. Paragraph (a) establishes the FINRA officer's authority to review transactions on his or her own motion, the grounds for declaring a transaction null and void, the timing standards (generally 30 minutes, or by the start of trading the following day in extraordinary circumstances), and the appeal framework under FINRA Rule 11894. Paragraph (b) establishes the clearly erroneous review standards — for transactions during Normal Market Hours, three categories tied to NMS Stock status, LULD Price Band availability, and corporate-action/Trading-Pause Reference Price issues; and for transactions outside Normal Market Hours (or eligible under paragraph (b)(1)(A)), a Numerical Guidelines table varying by price tier, Multi-Stock Event size, and leveraged ETF/ETN status, plus a list of additional discretionary factors.

Paragraph (c) defines the Reference Price — generally the consolidated last sale immediately prior to the transaction under review, with three categories of exceptions. Paragraph (d) addresses Multi-day Events involving severe valuation errors from grossly misinterpreted issuance information. Paragraph (e) addresses transactions occurring during regulatory trading halts, suspensions, or pauses. Supplementary Material .01 addresses FINRA's coordination with national securities exchange trade-break determinations, and Supplementary Material .02 addresses transactions occurring outside LULD Price Bands due to a member's technology or systems issue. FINRA Rule 11892 was most recently amended by SR-FINRA-2022-027 effective October 1, 2022, with 36 prior amendments extending back to its original adoption effective April 2, 1990.

FINRA Rule 11892 sits within the 11890 Clearly Erroneous Transactions cluster of the 11000 Uniform Practice Code as its second rule, immediately following FINRA Rule 11891's general definitional framework and immediately preceding FINRA Rule 11893's OTC equity securities framework.

FINRA Rule 11892(a): FINRA Officer Authority, Timing, and the Appeal Framework

FINRA Rule 11892(a)(1) vests review authority in a defined official — an Executive Vice President of FINRA's Market Regulation Department or Transparency Services Department, or any officer designated by such Executive Vice President (a "FINRA officer"), may, on his or her own motion, review any over-the-counter transaction involving an exchange-listed security occurring outside of Normal Market Hours (9:30 a.m. ET to 4:00 p.m. ET) or eligible for review pursuant to paragraph (b)(1), arising out of or reported through a FINRA-owned-or-operated, Commission-authorized trade reporting system.

The FINRA officer may declare such a transaction null and void upon determining either (A) the transaction is clearly erroneous (invoking FINRA Rule 11891's core definition), or (B) such action is necessary for the maintenance of a fair and orderly market or the protection of investors and the public interest (language that parallels the standard stated in FINRA Rule 11891 Supplementary Material .02). The timing standard — absent extraordinary circumstances, generally within 30 minutes after becoming aware of the transaction; in extraordinary circumstances, no later than the start of trading on the day following the date of execution — closely parallels the similar 30-minute/next-day-start framework of FINRA Rule 11892(e) and Supplementary Material .02, establishing this dual timing standard as a consistent baseline across the rule.

Paragraph (a)(2) establishes the notification-and-appeal framework — each party shall be notified as soon as practicable, and the aggrieved party may appeal in accordance with Rule 11894 — with two carve-outs from appealability: decisions made under Supplementary Material .02 regarding transactions outside LULD Price Bands, and rulings made by FINRA in conjunction with one or more other self-regulatory organizations.

FINRA Rule 11892(b)(1): Clearly Erroneous Review During Normal Market Hours — The LULD Plan Framework

FINRA Rule 11892(b)(1) establishes that, for transactions executed during Normal Market Hours, review for clearly erroneous status is generally unavailable — unless the transaction falls within one of three categories.

Category (A) addresses NMS Stocks not subject to the LULD Plan — for such stocks, the Numerical Guidelines of paragraph (b)(2) apply. This confirms that the LULD Plan — the Regulation NMS-based framework establishing Price Bands (upper and lower price limits within which a security must trade) for most NMS Stocks following the 2010 "Flash Crash" — has become the primary clearly-erroneous-review mechanism during Normal Market Hours for LULD-covered securities, with the older Numerical Guidelines framework serving as the residual mechanism for the (now presumably small) category of NMS Stocks the LULD Plan does not cover.

Category (B) addresses LULD-Plan-covered securities where Price Bands were unavailable, where a member's technology or systems issue caused a transaction outside applicable Price Bands (per Supplementary Material .02), or where the primary listing market has declared a regulatory trading halt, suspension, or pause under paragraph (e). For this category, a transaction is clearly erroneous if its price exceeds the Reference Price (for a buy) or falls below it (for a sell) by an amount equal to or exceeding the applicable Percentage Parameter defined in Appendix A to the LULD Plan.

Category (C) addresses corporate actions, new issues, or securities resuming trading after a Trading Pause without an auction, where the Reference Price itself is determined to be erroneous because it clearly deviated from the security's theoretical value — in which case FINRA may substitute a different Reference Price under paragraph (c)(2), with clearly-erroneous status then determined by reference to that substituted price using either the Numerical Guidelines or Percentage Parameters as applicable.

FINRA Rule 11892(b)(2): The Numerical Guidelines Table

FINRA Rule 11892(b)(2)(A) establishes the Numerical Guidelines table for transactions outside Normal Market Hours, or eligible for review under paragraph (b)(1)(A) — a transaction is clearly erroneous if its price deviates from the Reference Price by an amount equal to or exceeding the applicable percentage. The table establishes price-tiered thresholds: for reference prices up to twenty-five dollars, 10% during the Normal-Market-Hours-eligible category and 20% outside Normal Market Hours; for reference prices between twenty-five dollars and fifty dollars, 5% and 10% respectively; and for reference prices above fifty dollars, 3% and 6% respectively — confirming an inverse relationship between a security's price level and the percentage deviation tolerated, consistent with the general market-structure principle that higher-priced securities exhibit proportionally smaller typical price movements.

The table also establishes two Multi-Stock Event categories — events involving five or more but fewer than twenty securities executed within five minutes or less use a flat 10% threshold (both inside and outside Normal Market Hours), while events involving twenty or more such securities use a 30% threshold subject to paragraph (b)(2)(B)'s additional procedures. A final row addresses leveraged ETF/ETN securities — for these, the otherwise-applicable Normal Market Hours Numerical Guideline is multiplied by the leverage multiplier (e.g., 2x for a 2x leveraged product), reflecting that a 2x leveraged ETF's price movements are mechanically amplified relative to its underlying index, such that a given percentage deviation that would be clearly erroneous for an unleveraged security might represent entirely ordinary movement for its 2x-leveraged counterpart.

FINRA Rule 11892(b)(2)(B) and (C): Large Multi-Stock Events and Additional Discretionary Factors

FINRA Rule 11892(b)(2)(B) addresses Multi-Stock Events involving twenty or more securities — recognizing that during such events, the number of affected transactions may be such that immediate finality is necessary to maintain a fair and orderly market and protect investors and the public interest. For such events, FINRA may use a Reference Price other than the consolidated last sale, will coordinate with other self-regulatory organizations to determine an appropriate review period (which may exceed the triggering five-minute window) and select reference points in time, and will nullify as clearly erroneous all transactions at prices 30% or more away from the selected Reference Price during that review period.

Paragraph (b)(2)(C) establishes an extensive list of additional factors a FINRA officer may consider for transactions outside Normal Market Hours or eligible under paragraph (b)(1)(A) (except in Multi-Stock Events involving five or more securities) — including but not limited to system malfunctions or disruptions; volume and volatility; leveraged-derivative products tracking more than 100% of an index's movement; news releases; recent trading halts/resumptions; IPO status; stock splits, reorganizations, or other corporate actions; overall market conditions; Opening and Late Session executions; consolidated tape validity; primary market indications; and executions inconsistent with the security's trading pattern — each considered with a view toward maintaining a fair and orderly market and protecting investors and the public interest, the same standard this dictionary has now encountered repeatedly throughout paragraphs (a) and (b).

FINRA Rule 11892(c): The Reference Price and Its Exceptions

FINRA Rule 11892(c) establishes the default Reference Price — the consolidated last sale immediately prior to the execution(s) under review — with three categories of exception. The first exception (paragraph (c)(1)) is the Multi-Stock Event framework of paragraph (b)(2)(B). The second exception (paragraph (c)(2)) addresses the erroneous-Reference-Price scenario of paragraph (b)(1)(C) — for corporate actions or new issues, FINRA considers factors including the new issue's offering price, the stock-split ratio applied to the prior closing price, theoretical prices derived from exchange ratios or spin-off terms, and (for an OTC up-listing) the prior day's FINRA Trade Dissemination Service final closing report; for securities resuming trading after a Trading Pause without an auction, the Reference Price becomes the last effective Price Band that was in a limit state before the Pause.

The third exception (paragraph (c)(3)) is a catch-all — other circumstances, such as relevant news, extreme market volatility, sustained illiquidity, or widespread system issues, where a different Reference Price is necessary for the maintenance of a fair and orderly market and the protection of investors and the public interest, provided the circumstances occurred outside Normal Market Hours or are eligible for review under paragraph (b)(1)(A).

FINRA Rule 11892(d): Multi-day Events and the "Severe Valuation Error" Standard

FINRA Rule 11892(d) addresses a category distinct from the single-execution or short-window Multi-Stock Event scenarios paragraphs (b) and (c) address — a series of transactions in a particular security on one or more trading days may be viewed as one event (an "Event") if all such transactions were effected based on the same fundamentally incorrect or grossly misinterpreted issuance information resulting in a severe valuation error for all such transactions.

For such an Event, a FINRA officer must declare all transactions occurring during the Event null and void not later than the start of trading on the day following the last transaction in the Event — or, if trading is halted before the valuation error is corrected, prior to the resumption of trading. Two important limitations apply — no action under paragraph (d) may address transactions that have reached settlement date (connecting directly to the settlement-finality concerns this dictionary has traced throughout its coverage, from FINRA Rule 11100(c)'s non-cancellation principle onward) or transactions resulting from an initial public offering. Cross-SRO coordination is required where practicable, and any paragraph (d) action operates without regard to the Percentage Parameters or Numerical Guidelines otherwise applicable — reflecting that a severe valuation error spanning multiple days and based on fundamentally incorrect issuance information represents a category of problem the ordinary percentage-deviation framework was not designed to address.

FINRA Rule 11892(e): Transactions During Trading Halts

FINRA Rule 11892(e) addresses transactions executed during a regulatory trading halt, suspension, or pause — specifically in the scenario of any disruption or malfunction in the electronic communications and trading facilities of a self-regulatory organization or responsible single plan processor in connection with transmittal or receipt of such a halt, suspension, or pause. In this scenario, a FINRA officer must declare null and void any transaction occurring after the primary listing market declares the halt and before it officially ends — and, where a halt is prematurely lifted in error and then re-instituted, transactions occurring before the official final end are likewise nullified. The timing standard closely parallels paragraph (a)(1) — generally within 30 minutes, and in no circumstances later than the start of normal market hours the following trading day — and, like paragraph (d), operates without regard to the Percentage Parameters or Numerical Guidelines.

Supplementary Material .01: Coordination with National Securities Exchange Trade-Break Determinations

Supplementary Material .01 establishes FINRA's general policy of coordinating with other self-regulatory organizations regarding OTC transactions in exchange-listed securities reported to a FINRA system (such as a Trade Reporting Facility or Alternative Display Facility) — FINRA will generally follow a national securities exchange's determination to break a trade at or near the relevant price and time where doing so would be consistent with market integrity and investor protection, and conversely will leave a trade unbroken where any relevant exchange has left a related trade unbroken at or near the relevant price and time where breaking it would be inconsistent with those goals. This coordination policy reflects the broader theme this dictionary has observed of cross-SRO consistency — paragraphs (b)(2)(B) and (d)'s cross-SRO coordination requirements operate alongside this Supplementary Material's general coordination policy for the specific context of corresponding exchange-listed-security transactions.

Supplementary Material .02: The Member Technology/Systems Issue Framework

Supplementary Material .02 establishes the framework this dictionary encountered referenced in paragraph (b)(1)(B) — where a member's technology or systems issue causes a transaction reported to a FINRA system to occur outside applicable LULD Price Bands, a FINRA officer (on his or her own motion or at a member's request) shall review and deem such transaction clearly erroneous, subject to a certification requirement. A similar 30-minute/next-day-start timing standard applies, with notification and FINRA Rule 11894 appeal rights for members — though, per paragraph (a)(2), decisions under this Supplementary Material specifically are not appealable in the sense paragraph (a)(2) otherwise contemplates (a point this dictionary notes as a textual tension between paragraph (a)(2)'s carve-out and Supplementary Material .02(a)'s own appeal-rights language, without resolving it further absent additional guidance).

The certification requirement (paragraph (b) of this Supplementary Material) requires a member requesting review to certify, in FINRA-prescribed manner and form, that the transaction's occurrence outside the applicable Price Bands resulted from the member's bona fide technological or systems issue — a self-certification mechanism ensuring this specific review pathway is invoked only for genuine technology malfunctions, not as a general mechanism for unwinding unfavorable executions.

The Amendment History: 38 Dates Spanning Three Decades and the LULD Plan's Integration

FINRA Rule 11892's amendment history — 38 effective dates from its original adoption effective April 2, 1990 through SR-FINRA-2022-027 effective October 1, 2022 — represents one of the most extensively amended provisions in the 11000 Uniform Practice Code, well above, for example, FINRA Rule 11870's fourteen effective dates. The clustering of amendments in 2010-2022 — SR-FINRA-2010-032, SR-FINRA-2010-065, SR-FINRA-2011-014, SR-FINRA-2011-037, SR-FINRA-2011-039, SR-FINRA-2012-005, SR-FINRA-2012-038, SR-FINRA-2013-012, SR-FINRA-2013-041, SR-FINRA-2014-013, SR-FINRA-2014-021, SR-FINRA-2015-034, SR-FINRA-2019-011, SR-FINRA-2019-025, SR-FINRA-2020-008, SR-FINRA-2020-036, SR-FINRA-2021-004, SR-FINRA-2021-026, SR-FINRA-2022-008, SR-FINRA-2022-020, and SR-FINRA-2022-027 — reflects the market-structure reforms that followed the May 2010 "Flash Crash," including the LULD Plan's implementation and refinement, with Regulatory Notice 10-43 ("Amendments to FINRA Rules on Trading Pauses Due to Extraordinary Market Volatility and Clearly Erroneous Transactions in Exchange-Listed Securities," September 22, 2010) marking an early post-Flash-Crash amendment.

Connection to FINRA Rules 11110, 11810, 11890, 11891, 11893, and 11894

FINRA Rule 11892 connects directly to FINRA Rule 11891 — whose core "obvious error" definition underlies the clearly erroneous standard applied in FINRA Rule 11892(a)(1)(A), and whose Supplementary Material .02 fair-and-orderly-market/investor-protection standard is paralleled in FINRA Rule 11892(a)(1)(B), and whose absence of a 2010 SR-FINRA-2010-030 amendment FINRA Rule 11892 shares. It connects to FINRA Rule 11110 — the UPC Committee framework that FINRA Rule 11894's review process (which this dictionary anticipates examining next) operates within. It connects to FINRA Rule 11810(d)(1)(D) — whose requirement that members be prepared to defend the price at which a buy-in is executed relative to the current market at the time of the buy-in is another price-versus-market standard in the Uniform Practice Code. It connects to FINRA Rule 11890 — sharing Notice 10-04 as a selected notice. And it connects directly to FINRA Rule 11893 — the OTC equity securities counterpart this dictionary anticipates will parallel much of FINRA Rule 11892's framework for the non-exchange-listed context, and FINRA Rule 11894 — the UPC Committee review mechanism FINRA Rule 11892(a)(2), (d), and Supplementary Material .02 all reference for appeals.

Examination Relevance and Key Takeaways

FINRA Rule 11892 is the clearly erroneous transaction framework for exchange-listed securities — among the most technically dense and continuously amended provisions in the Uniform Practice Code, built around the post-Flash-Crash LULD Plan and Regulation NMS infrastructure.

The key points to retain are these:

FINRA Rule 11892(a) vests review authority in a designated FINRA officer, who may declare a transaction null and void if clearly erroneous or necessary for fair-and-orderly-market/investor-protection purposes, generally within 30 minutes (or by the start of the next trading day in extraordinary circumstances), with FINRA Rule 11894 appeal rights subject to carve-outs for LULD-Price-Band-related and joint-SRO determinations; FINRA Rule 11892(b)(1) limits Normal-Market-Hours review to three categories — non-LULD NMS Stocks (Numerical Guidelines apply), LULD-covered securities with unavailable Price Bands, member-tech-issue-caused out-of-band trades, or post-halt trades (Percentage Parameters apply), and corporate-action/Trading-Pause scenarios with an erroneous Reference Price; FINRA Rule 11892(b)(2) establishes price-tiered Numerical Guidelines (10%/20%, 5%/10%, 3%/6% for increasing price tiers, inside/outside Normal Market Hours respectively), Multi-Stock Event thresholds (10% for 5-19 securities, 30% with special procedures for 20+), a leverage-multiplier adjustment for leveraged ETF/ETN products, and an extensive list of additional discretionary factors; FINRA Rule 11892(c) defines the Reference Price as generally the consolidated last sale immediately prior, with exceptions for large Multi-Stock Events, erroneous reference prices (using new-issue offering prices, split ratios, exchange ratios, or post-Pause limit-state Price Bands), and other fair-and-orderly-market circumstances; FINRA Rule 11892(d) addresses Multi-day "Events" involving severe valuation errors from misinterpreted issuance information, excluding settled transactions and IPOs, without regard to the usual percentage thresholds; FINRA Rule 11892(e) addresses trading-halt-period transactions under a similar without-regard-to-thresholds and 30-minute/next-day framework; Supplementary Material .01 establishes FINRA's general deference to coordinated exchange trade-break determinations; and Supplementary Material .02 establishes the certified-technology-issue pathway for transactions outside LULD Price Bands. The rule was most recently amended effective October 1, 2022 through SR-FINRA-2022-027, with 36 prior amendments extending to its 1990 adoption, and seven selected notices — 98-21, 99-29, 00-10, 03-11, 10-04, 10-43, and 16-04.
