How to Audit an AI Trading Agent’s Decisions

Auditing an AI trading agent’s decisions begins with a clear, documented process that checks data quality, model output, risk‑limit enforcement, and execution results. By tracing each step from market feed to final position, you can identify gaps, confirm compliance with owner‑signed limits, and understand where uncertainty remains. For related context, see How to give an AI agent a trading account.

What data should be verified before the agent trades?

The first line of defense is the market data feed. Every price, volume, or order‑book snapshot must include a source identifier, timestamp, and any freshness warnings. Missing or unverified data should never be treated as zero, because that can lead to unintended orders.

• ·Confirm the data source is authorized and matches the normalized interface used by the agent.
• ·Check timestamps against a reliable clock and flag any stale updates.
• ·Record any warnings about coverage gaps or anomalies for later review.

How can you trace the agent’s decision logic?

A robust audit log records the exact inputs the model received, the model’s output (e.g., suggested order size and price), and the risk limits applied at that moment. This creates a durable mutation identity that can be reconciled later.

1. 01Log raw market inputs and any preprocessing steps.
2. 02Capture the model’s raw recommendation before any limits are applied.
3. 03Record the final order parameters after owner‑signed limits (size, notional, loss caps) are enforced.

What risk limits must be checked?

Owner‑signed limits define the maximum order size, daily notional exposure, daily loss tolerance, and expiry for each agent key. Auditors should verify that the agent key’s scope matches these limits for every order. For related context, see When Should an AI Trading Agent Pause After Repeated Errors?. For related context, see How to Set a Maximum Order Size for Your AI Trading Agent.

• ·Order size does not exceed the maximum set by the owner.
• ·Daily notional exposure stays within the owner‑approved ceiling.
• ·Any loss incurred in a day respects the owner‑defined loss cap.
• ·Orders are rejected or paused when limits are breached.

How do you verify execution and reconciliation?

Execution data must be compared against the intended order parameters. Because a timeout does not prove failure, auditors need explicit success or error states from the venue.

1. 01Match the order ID in the audit log to the venue’s fill report.
2. 02Confirm the filled quantity, price, and any partial fills.
3. 03Reconcile the resulting position change with the account state reported by the normalized interface.
4. 04Document any discrepancies for further investigation.

When should an emergency stop be used?

An emergency stop revokes the calling agent key, halting further managed activity. It does not automatically close open positions or cancel token allowances, which must be reviewed and acted upon by the owner.

• ·Trigger the stop when risk limits are repeatedly breached or when data integrity cannot be assured.
• ·Perform a separate owner‑authorized review to unwind or adjust existing positions.
• ·Document the stop event and the subsequent owner actions.

“An audit is only as strong as the data it trusts; always verify source, timestamp, and freshness before trusting any decision.”
