Welcome to Identifying and Handling Clearly Erroneous Transactions: the narrow set of rules that let FINRA unwind a trade the market never meant to make, and the guidelines that decide whether a bad print is bad enough to qualify.
Exam Weight: about 1 of the 50 scored items (CertFuel planning estimate; FINRA publishes weights only by function, and Function 1, Trading Activities, is 41 items / 82%)
What You'll Learn
In this unit, you'll cover:
- Minimum Criteria Necessary for a Transaction to Qualify as Clearly Erroneous: what an obvious error in a term means, the situations these rules target, and why an admitted entry mistake may not be enough on its own
- Nullifying an Exchange-Listed Transaction: who reviews an off-exchange trade in a listed security, on what two grounds, inside what clock, and what remedy the officer actually holds
- Reviewability and the Two Price Yardsticks: the three gateways that open a review during Normal Market Hours, and when the Percentage Parameters apply instead of the Numerical Guidelines
- Multi-day Events, Trading Halts and Exchange Coordination: the two situations where the officer must act without regard to any guideline, and the transactions no action can reach
- Clearly Erroneous Transactions in OTC Equity Securities: the separate guideline table, the longer clock, and that FINRA expects the parties to settle privately instead
- Appealing a Nullification to the Uniform Practice Code Committee: the thirty-minute written appeal, the three determinations the clearly erroneous appeal rule bars, and what the Committee can do
Why This Matters
A trader who enters the wrong price or the wrong order type owns that print. These rules decide the narrow cases where the trade comes back out, and they are drafted so that the answer is usually no.
The unit moves from the definition through the two markets it covers and out to the appeal:
- What counts as an obvious error, and what FINRA weighs when it decides
- Which price the trade is measured against, and by how much it has to miss
- What happens when the error runs across days, or a halt message never arrives
- How a broken trade gets challenged, how fast, and who decides
Let's start with what makes a transaction clearly erroneous in the first place.
