Cancel All Orders

Description

Cancel every open or partially-filled order belonging to the caller, optionally scoped to a single market. Only the caller's own orders are affected — other users' resting orders on the same market are untouched.

HTTP Request

DELETE /spot/orders (JWT or API Key)

Weight

0 — order endpoints are not subject to per-IP weight limits. A per-engine mpsc backlog is enforced; on overflow the response is 503 ENGINE_BUSY.

Request Parameters

Name	Type	Required	Description
symbol	STRING	NO	Market id (e.g. DFUSDT). Omit to cancel across all markets the caller has open orders on. Case-sensitive.

Response Example

200 OK

Field	Notes
canceled	Array of every order that was transitioned to canceled by this request. Orders already in a terminal state (filled / canceled / rejected) are silently skipped and not included.
status	Always canceled for every item in the array. See Order Status.
filled_qty	Amount filled before the cancel; may be non-zero for partially-filled orders.
created_at, updated_at	Unix seconds. updated_at reflects the cancellation time.

Note: An empty canceled array ({"canceled": []}) is a valid successful response if the caller has no open or partially-filled orders (or none matching the given symbol).

Error Responses

HTTP	error	When
503	ENGINE_BUSY, ENGINE_RESTARTING, spot trading disabled	Transient; retry with backoff.
