Set Disconnection Protect (Deadman Switch). Through this interface, call this interface to automatically cancel all orders of the set trading pair after the specified time. If this interface is not called again for renewal or cancellation before the set time, the system will help the user to cancel the order of the corresponding trading pair. Otherwise it will not.
The order cancellation delay is between 0 and 10 seconds, and the order will not be canceled in real time. When the system cancels the order, if the transaction pair status is no longer operable to cancel the order, it will not cancel the order
