# Cancel on Disconnect

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

</div>

`cancelAllOrdersAfter` provides a "Dead Man's Switch" mechanism to protect the client from network malfunction, extreme latency or unexpected matching engine downtime. The client can send a request with a timeout (in seconds), that will start a countdown timer which will cancel *all* client orders when the timer expires.

The recommended use is to make a call every 15 to 30 seconds, providing a timeout of 60 seconds.
