Set Auto-Cancel

Set a dead man's switch that cancels all your open orders at the chosen time. The time must be at least 5 seconds in the future. Send 0 to clear an active schedule without triggering it; posting a new time replaces the current one.

The switch fires once, then clears itself. It does not cover orders you place after it fires, so re-arm it if you still need protection.

An account can trigger auto-cancel up to 1000 times per UTC day. After that, the API rejects new schedules with the error auto_cancel_daily_limit_reached until the next UTC day. Clearing a schedule is always allowed. To check the active deadline and today's trigger count, call Get Auto-Cancel Status.
