# 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.
|
|
|
|
Requires proxy signature, see [proxy signing](/http/signing#2-proxy-signing).

Error identifier. For domain rejections and transport errors
|
|
(`401`/`404`/`429`/`500`) this is a stable, machine-readable snake_case
|
|
identifier that is part of the API contract and safe to branch on, e.g.
|
|
`insufficient_margin`, `insufficient_balance`, `order_not_found`,
|
|
`reduce_only_invalid`, `unauthorized`, `not_found`. For `400` it is a
|
|
human-readable validation detail whose wording may change. See the Error
|
|
handling guide for the domain identifiers. (Post-only / Fill-or-Kill
|
|
outcomes are order statuses such as `post_only_rejected`, not
|
|
rejections.)

Bad request — the request was malformed or failed validation (bad query
