Series 24 Trading Supervision Practice Questions

Correct answer: B. Information barriers (Chinese wall) between research and trading

Trading ahead of an imminent, market-moving research report using knowledge gained from within the firm is precisely what information barriers are designed to prevent, since research analysis of this kind is treated as material nonpublic information until published. A supervisory failure allowing the trading desk to access and act on it before release is an information-barrier breakdown, not a Reg M, Reg SHO, or trade-reporting issue.

• AA. Regulation M governs trading restrictions during securities distributions and is unrelated to the misuse of internal research information by a trading desk.
• BB. Using undisclosed knowledge of an impending research report to trade ahead of it is exactly the scenario information barriers are designed to prevent, so a breakdown here points directly to a Chinese wall failure between research and trading.
• CC. Regulation SHO locate procedures concern the ability to borrow and deliver shares for short sales, not the misuse of material non-public research content.
• DD. Trade reporting timeliness concerns how quickly executed trades are reported to the tape, which has nothing to do with trading ahead of an internal research report.

Correct answer: B. This is a prohibited trade-through unless a specific Rule 611 exception applies (e.g., the order was flagged as an intermarket sweep order, or another enumerated exception is met)

Rule 611 generally prohibits a trading center from executing an order at a price inferior to a protected quotation displayed at another trading center. The rule is not strict liability, though. It lists defined exceptions, such as intermarket sweep orders (the sender also routes to take out the protected quotes), benchmark trades, and system-problem or self-help situations. A trade-through is therefore a violation unless one of those exceptions applies. The rule covers NMS stocks, not just options, which have their own linkage rules. The executing venue's speed is not an exception.

• AA. Rule 611 isn't a strict-liability, no-exceptions rule. It explicitly carves out enumerated exceptions (like intermarket sweep orders) under which an execution at an inferior price is permitted.
• BB. Correct. Executing through a protected quotation is a prohibited trade-through under Rule 611 unless one of the rule's enumerated exceptions applies, such as the order being flagged as an intermarket sweep order.
• CC. Rule 611's order protection framework applies to NMS stocks (equities), not options. This describes the wrong asset class.
• DD. Being faster than the other venue isn't an exception under Rule 611. The rule turns on whether an enumerated exception applies, not on relative execution speed.

Correct answer: A. Marking the close

Marking the close is the manipulative practice of executing trades near the close specifically to affect the reported closing price, often to benefit a related position (e.g., options, futures, or a mark-to-market valuation). It is prohibited manipulative conduct under the Exchange Act's antifraud/antimanipulation provisions and FINRA Rule 2020. Painting the tape instead refers to a broader series of transactions meant to create a false impression of active trading, without the specific closing-price focus.

• AA. Executing trades late in the session specifically to push the closing price to benefit a related position is the classic definition of marking the close.
• BB. Painting the tape refers more broadly to creating a false appearance of active trading through a series of transactions; this scenario's specific focus on manipulating the closing price is more precisely marking the close.
• CC. Wash trading involves offsetting trades with no genuine change in beneficial ownership, which is not what's described here.
• DD. Front running involves trading ahead of a known, pending customer order, which is unrelated to manipulating a closing price.

Correct answer: A. Within 15 minutes of the time of execution, the current standard reporting timeframe

The TRACE outer limit for most corporate bond transactions remains 15 minutes: Rule 6730(a) requires reporting as soon as practicable, and no later than 15 minutes after the time of execution. FINRA proposed shortening that limit to 1 minute and the SEC approved the amendment, but it never took effect, and in Regulatory Notice 25-17 (December 2025) FINRA stated that it is not moving forward with the proposal and is keeping the 15-minute standard. Candidates should not treat the 1-minute figure as current law. It should also not be confused with the 10-second window for equity trade reporting, and end-of-day reporting is not permitted for these transactions. Different time frames apply to certain products, so limited exceptions exist.

• AA. Correct. 15 minutes remains the current TRACE reporting standard for most corporate bond transactions under Rule 6730(a). The SEC approved a FINRA amendment to shorten this to 1 minute, but it never took effect, and in Regulatory Notice 25-17 (December 2025) FINRA stated that it is not moving forward with the proposal and is keeping the 15-minute standard.
• BB. Incorrect. This describes a rule change that was approved by the SEC but never took effect. In Regulatory Notice 25-17 (December 2025) FINRA stated that it is not moving forward with the 1-minute proposal; 15 minutes remains the current standard under Rule 6730(a).
• CC. End-of-day reporting is far looser than the current TRACE requirement, which operates on a near-real-time basis.
• DD. 10 seconds is the equity trade reporting standard, not the TRACE corporate bond standard, which remains 15 minutes.

Correct answer: A. As soon as practicable, but no later than 10 seconds after execution

Equity trade reporting rules require members to report transactions in NMS stocks as soon as practicable, and in any event no later than 10 seconds after execution. This is a distinct, longer-standing standard from TRACE corporate bond reporting (currently 1 minute for most trades), and candidates should not merge the two timeframes even though both were recently the subject of speed-up discussions.

• AA. Correct. Trades in NMS stocks must generally be reported to the applicable trade reporting facility as soon as practicable, but no later than 10 seconds after execution.
• BB. 1 minute is the TRACE corporate bond reporting standard, not the equity trade reporting timeframe, which is much shorter (10 seconds).
• CC. 15 minutes was an older TRACE bond standard and isn't the reporting timeframe for equity trades, which must be reported within 10 seconds.
• DD. End-of-day reporting is far looser than the near-real-time (10-second) standard that applies to equity trade reporting.

Correct answer: A. $0.0030 per share

Rule 610(c) caps access fees at $0.0030 (30 mils, or 0.3 cents) per share for NMS stocks priced at $1.00 or more, intended to prevent excessive fees from undermining the reliability of quoted prices used in the trade-through and locked/crossed-market provisions. Choice B is off by a factor of ten, C confuses a per-share cap with a percentage-of-notional cap, and D ignores that Reg NMS imposes a binding cap regardless of an exchange's own schedule.

• AA. Correct. Rule 610 caps access fees at $0.0030 (30 mils) per share for protected quotations in NMS stocks priced at $1.00 or more.
• BB. This is off by a factor of 10. $0.03 per share is far above the actual $0.0030 cap Rule 610 imposes for stocks priced $1 or more.
• CC. The percentage-of-notional-value cap (0.30%) applies to the separate sub-$1.00 stock pricing tier under Rule 610, not to stocks priced at $1.00 or more, which use a flat per-share cap.
• DD. Rule 610 does impose a binding cap on access fees. Trading centers cannot set fees unilaterally without regard to this ceiling.

Correct answer: C. The firm must evaluate and address execution quality for customer orders; routing incentives do not replace the duty.

Best execution requires regular, diligent review of execution quality for customer orders. Rebates and affiliate relationships create conflicts but do not replace that duty, and worse realized quality calls for documented corrective action.

• AA. Disclosure and rebates do not excuse the duty to seek the most favorable reasonably available terms.
• BB. The duty applies to retail customer orders; disclosure alone does not satisfy it.
• CC. The firm must review execution quality and act on poor results despite routing incentives.
• DD. Affiliated routing and rebates are permitted if conflicts are managed and execution quality is reviewed; they are not banned outright.

Correct answer: A. No later than the beginning of regular trading hours on the settlement day following the 13th consecutive settlement day the fail has persisted

Rule 203(b)(3) requires a participant to close out a fail-to-deliver position in a threshold security no later than the beginning of regular trading hours on the settlement day following the thirteenth consecutive settlement day the fail has persisted. Until the position is closed out, the participant and any broker-dealer it clears for may not accept short sale orders in that security without first borrowing the security or arranging to borrow it (pre-borrow). The other choices invent deadlines or wrongly describe the rule as only a disclosure obligation.

• AA. Correct. Under Reg SHO Rule 203(b)(3), once a fail-to-deliver in a threshold security has persisted for 13 consecutive settlement days, the participant must close out the position no later than the beginning of regular trading hours on the following settlement day.
• BB. There's no fixed 3-day, then-open-ended deadline. Reg SHO ties the mandatory close-out to the number of consecutive settlement days (13) the fail has persisted, with ongoing monitoring, not a one-time window.
• CC. The close-out deadline is tied to the 13-consecutive-settlement-day fail threshold, not to a calendar-month cutoff.
• DD. Reg SHO Rule 203(b)(3) imposes a mandatory close-out obligation, not merely a disclosure requirement, once the persistent fail threshold is reached.
