How to cancel buy limit if target fills

[MakesTrades23]

Often I find myself wanting to leave a buy limit order to add to a position but then I would also like that limit order (adding to position) to cancel if my original target fills. Is there a way I can do this?

Thanks for your time.

Hello, thanks for writing in. The best way to do this would be through the use of Exit orders for your stop and target rather than using SetStopLoss/SetProfitTarget. The Exit methods can be canceled where the Set methods can not be directly canceled unless ExitLong()/ExitShort() is called. While using Exit orders, you will be able to keep track of each order using OnExecutionUpdate/OnOrderUpdate and cancel the pending entry order if the stop or target of the original position closes. See the related example here:
