Set Auto-Cancel

Set a dead man switch that will cancel all open orders at the specified time. Time must be at least 5 seconds in the future, or 0 to clear an active schedule without triggering it. Posting a new auto-cancel replaces the previous one.

The switch is one-shot: once the deadline elapses and your open orders are cancelled, the schedule clears automatically. Orders you place after the fire are not affected by the expired deadline — re-arm to extend protection.

Each account may trigger auto-cancel at most 10 times per UTC day. Once that limit is reached, further attempts to arm a schedule are rejected with auto_cancel_daily_limit_reached until the next UTC day; clearing an existing schedule (time: 0) is always allowed.

Use GET /v1/account/auto-cancel to check the current deadline, today’s trigger count, and when the daily counter resets.
