How to implement order cancel order function

[Playdc]

I am wondering if there is a built in function to implement order cancel order function. For example, one order for profit target, the other order for loss protection. Once one order is executed, the other order would be automatically cancelled.

Hello,

Thank you for your post.

Set methods, like SetStopLoss and SetProfitTarget, are submitted as OCO when submitted together.

If you don't want to use set methods, for true OCO you would need to use the Unmanaged Approach to tie orders together using OCO IDs.

Hi Gaby, thank you for the clarification. I checked the link you provided for unmanaged order. I have one question. If I use SetStopLoss and SetProfitTarget, I need to use them for curreevery bar. It seems if they are not filled on current bar, they would be cancelled. You need to use them on next bar. While for unmanaged order method, the order will truly live until using cancelorder method. This is what you mean a true OCO. Am I correct?

By true OCO, I mean that they are actually tied via OCO (meaning one will cancel when the other fills).
