Unauthorized 500-Lot Fill Versus a 50-Lot Client Order
At 10:02 a broker-dealer's order desk receives a client instruction to buy 50 lots of a PMEX wheat futures contract at market. The dealer enters 500 lots. At 10:42, before the exchange's trade-capture cutoff, the desk notices. The market has risen 1.8%; closing the extra 450 lots would lock a loss of PKR 14 million. The firm's error-account policy permits error positions only up to PKR 2 million and requires compliance approval for any client allocation. The client, when told only that 'there is a quantity issue,' says 'keep the extra 450 lots; I like the direction.' The salesperson wants to confirm the client's instruction in writing as a new order and book the profit/loss to the client. The firm's trade-error procedure requires immediate escalation, evidence retention, and exchange notification of errors above a threshold.
1. What are the desk's immediate obligations after discovering the 500-lot fill?
Read the worked answer
The desk must immediately escalate to risk and compliance, stop further trading in the contract unless authorized, and preserve the order ticket, recorded instructions, timestamps and communications. It should identify the unauthorized 450 lots separately from the client's authorized 50 lots and calculate the exposure and loss at current prices. It must not conceal the error, book it silently to the client, or wait for the market to reverse. The firm should decide whether to hedge or offset the excess within approved authority, taking care not to create further unauthorized risk. Because the potential loss of PKR 14 million exceeds the PKR 2 million error-account limit, senior approval is required. If the error exceeds the exchange threshold, the firm must notify the exchange within the required timeframe. The client should not be told a misleading partial story; the full quantity and loss must be disclosed before any request for consent.
2. Can the client's 'keep the extra 450 lots' statement ratify the unauthorized fill? Explain the conditions.
Read the worked answer
Not on the facts. The client was told only that there was a 'quantity issue,' not that the firm had entered 500 lots instead of 50, that the extra 450 lots represented a PKR 14 million loss, or that the client was not obliged to accept them. Effective ratification requires full disclosure of the error, the quantity, the price, the current loss and the risks, followed by a clear and voluntary instruction. If, after full disclosure, the client independently decides to buy the extra 450 lots, the firm should treat that as a new order with a written confirmation, suitability assessment and recorded consent. The firm should not retroactively allocate the unauthorized fill to the client or use the client's initial vague statement to avoid the error-account process. If the client refuses, the excess must be handled under the error-account policy with compliance approval and any required reporting.
3. What reporting and remediation should follow once the position is controlled?
Read the worked answer
After controlling the position, compliance should document the root cause, the timeline, the persons involved, the client communications and the final profit or loss. The firm should assess whether the error is reportable to the exchange and make the notification within the applicable deadline; internal risk and senior management should also be informed. The client's account should be corrected so that only authorized trades remain, and any loss charged to the client must be supported by clear consent or contractual rights. The firm should review order-entry controls, such as quantity limits, dual checks and pre-trade validation, and retrain or discipline staff as appropriate. It should also test whether the error-account limit was breached and whether escalation was timely. The remediation should focus on preventing recurrence, not just on closing the position.
