Auto breakeven to trailing stop loss

convert an auto-breakeven on a bracket to a trailing stop

I might have find a workaround: I create an entry order ticket with 2 brackets. In the first bracket the Stop Type is Stop, and I configure it with breakeven, for the second bracket, the Stop Type is Trail.Stop, and I set the QTY of each bracket the same as the main order ticket. But I am not sure if this is correct or not. If one bracket gets triggered and the specified QTY of position is closed, will the other bracket be cancelled by the system? If not, the other bracket might create a short position. I tried this in a trial account, and it seems to be working, if one bracket gets triggered, the other will be cancelled. I have a ongoing discussion with support on this.

interesting. what did you ultimately conclude on this with support? does your idea work?
