Auto Cancel All after position is closed

[GoldBrotha]

If I have an open position of say one contract, and a stop and limit target in place, but decide to exit early via either 'flatten all' or by placing another order on the dom somewhere to get filled asap, it would be good if all pending orders could be automatically cancelled as soon as my position is back at net 0.

Let me know if I'm not explaining this in a clear way.
