}Cancel all orders after a timeout
Cancel all orders after a timeout.
Arm, refresh or disarm a dead man’s switch. If the timer is not refreshed before it runs out, the exchange cancels your resting orders with terminalReason CANCEL_ALL_AFTER: GTC and other resting limit orders, triggered TP/SL legs resting on the book, and TWAP parents that are not reduce-only. Untriggered TP/SL and other conditional orders on a position, reduce-only TWAPs and RFQ quotes stay; legs still pending on a cancelled entry order end with it, as on any cancel. Call it again before the deadline to push the deadline out; send timeoutMs 0 to disarm. One timer covers the whole account, or one trading pair when tradingPairId is set; the two scopes are separate timers. A timer that fires is spent, so arm it again to keep the switch on. Works during a maintenance pause, like cancels.

Ed25519 session-key request signing. Every authenticated request carries three headers: X-Monaco-PublicKey (64-char lowercase-hex session public key), X-Monaco-Timestamp (Unix milliseconds, within 30s of server time), and X-Monaco-Signature (hex ed25519 signature). The signature is over METHOD\npath?query\ntimestamp_ms\nSHA256_hex(body), where the body hash is the SHA-256 of the empty byte string when there is no body. Obtain the session keypair from POST /api/v1/auth/challenge followed by POST /api/v1/auth/verify.
Body
Milliseconds from now until your resting orders are cancelled: 0 disarms, otherwise 5000 to 900000 (5 seconds to 15 minutes). Each call replaces the previous deadline.
x <= 90000030000
Scope the timer to one trading pair. Omitted, the timer covers every market. Required for a delegated session.

Response
OK
The timeout that was set, echoed back; 0 when disarmed
30000
When the exchange cancels your resting orders unless you call again first (ISO 8601). Absent when the timer was disarmed.
"2026-06-01T00:00:30Z"
The trading pair the timer covers; absent for the account-wide timer
