Erroneous Reports, Errors, Cancels, and Rebills

Quick Answer

A trade error is an incorrect order execution (wrong security, quantity, price, account, or side) that the firm fixes with a cancel and rebill, absorbing any loss itself. An erroneous report is different: on options exchanges, a misreported price does not void the trade, and the actual execution price stays binding.

When a registered representative makes a mistake executing an order, the firm must fix it quickly and fairly. Understanding how trade errors are handled is foundational to the rest of this unit.


What Counts as a Trade Error?

A trade error occurs when an order is executed incorrectly. Common examples include:

  • Wrong security: buying stock in Company ABC instead of Company ABX
  • Wrong quantity: executing 500 shares instead of 50
  • Wrong price: entering a limit at $25 instead of $35
  • Wrong account: placing the trade in the wrong customer's account
  • Buy/sell reversal: buying when the customer wanted to sell (or vice versa)
  • Wrong customer allocation: assigning an executed trade to the wrong customer
  • Failure to follow instructions: not executing the order the customer actually gave

Who Bears the Loss?

The core principle is simple: the customer must not be disadvantaged by any trade error.

  • The firm absorbs the loss from correcting the error, not the customer, and not the representative personally
  • If the error accidentally produces a profit, that profit belongs to the firm (not the rep), unless the firm's written policy states otherwise
  • The registered representative and firm are responsible for correcting errors promptly

Exam Tip: Gotchas

If a question describes a rep who mistakenly buys 500 shares instead of 50, the firm bears the loss on the extra 450 shares. The customer gets the 50 shares at the correct price. The rep cannot keep any profit from the error; it belongs to the firm.

A correction must be supported by objective facts and documented; the trading center records it in an error account and must maintain written procedures and surveillance for error corrections. A change to an account designation, including an error account, requires written approval by a qualified registered principal who has been informed of, and documents, the essential facts.


How Are Trade Errors Corrected?

The standard procedure for correcting a trade error involves two steps:

  1. Cancel the original erroneous transaction (removes the incorrect trade)
  2. Rebill the corrected transaction (replaces it with the right trade)

Key Requirements

  • Cancel/rebill must be processed through the firm's operations department (not handled informally by the rep)
  • Requires supervisory approval before processing
  • Both the cancel and the rebill appear on the firm's blotter (daily record of transactions)
  • Both entries are subject to regulatory review
  • A cancellation removes a trade report on the date it was submitted; a cancellation after that point is generally reported as a reversal instead, and the exact process depends on the applicable FINRA reporting facility
  • A corrected report may be accepted without cancelling the original only where that facility's procedures permit it; do not treat "cancel and rebill" as one universal process across every facility

Red Flags

  • Frequent cancels and rebills may trigger supervisory review or regulatory investigation
  • Patterns of cancel/rebill activity can indicate:
    • Unauthorized trading (rep trading without customer permission, then reversing unfavorable trades)
    • Allocation fraud (placing trades, then allocating winners to favored accounts and moving losers elsewhere)

What Is an Erroneous Report?

An erroneous report is different from a trade error. This applies specifically to options exchanges:

  • An erroneous report of an execution does not make the trade void
  • The actual execution price is binding, regardless of what was reported
  • If a floor broker reports an incorrect price to a customer, the actual execution price controls

Think of it this way: The trade itself happened correctly on the exchange floor. The mistake was only in the communication about what price was achieved. The real price governs.

Exam Tip: Gotchas

A common mix-up is trade error vs. erroneous report. A trade error means the wrong execution happened (corrected with cancel/rebill). An erroneous report means the execution was correct, but the reported price was wrong. An erroneous report does NOT void the trade; the actual execution price is binding under the exchange's erroneous-report rules.


What Should You Check on Exam Day?

  • Who absorbs the loss on a trade error: the firm, never the customer or the rep, and any accidental profit also belongs to the firm.
  • The correction path: cancel the wrong trade, rebill the correct one, through operations with supervisory approval, both on the blotter.
  • Trade error (wrong execution, fixed with cancel/rebill) vs. erroneous report (correct execution, wrong reported price, trade stays valid).
  • Frequent cancels/rebills as a red flag for unauthorized trading or allocation fraud.
