# Automatic Order Cancellation

#### /sapi/v1/trade/cancel-after 

Request type: POST

Signature verification: Yes

Interface permission: Trade

Rate Limit: 144 requests per UID per 3 seconds. This limit is shared across all trading interfaces (72 requests/3 seconds) and query interfaces (72 requests/3 seconds) for all symbols and contracts with different expiry dates for a given UID.

Interface description: SunX Futures launches the automatic order cancellation interface to prevent API users from incurring unexpected losses in the event of network failures or client system failures that result in a loss of communication with the SunX system. When users experience an unexpected disconnection from SunX's system, this interface automatically cancels all pending orders (including both opening and closing orders) to mitigate potential losses through its Dead Man's Switch functionality. If the interface is not called again within the specified period, all of the user's pending futures orders will be canceled.
