# Cancel on Disconnect

> Dead Man's Switch mechanism to cancel all orders after a timeout

UWS
uws.kraken.com/v2/private
cancel\_all\_orders\_after

`cancel_all_orders_after` provides a "Dead Man's Switch" mechanism to protect from network malfunction, extreme latency or unexpected matching engine downtime.

* The client sends request with a timeout (in seconds), that will start a countdown timer in the trading engine which will cancel all client orders when the timer expires.
* The client must keep sending new requests to reset the trigger time, or deactivate the mechanism by specifying a timeout of 0.
* If the timer expires, all orders in the account are cancelled and the feature is disabled until the next `cancel_all_orders_after` request.
* The recommended use is to make a call every 15 to 30 seconds, providing a timeout of 60 seconds. This allows the client to keep the orders in place in case of a brief disconnection or transient delay, while keeping them safe in case of a network breakdown.

> [!NOTE]
>
> It is recommended to disable the timer ahead of scheduled trading engine maintenance (if the timer is enabled, all orders will be cancelled when the trading engine comes back from downtime).
