S/L and T/P settings automatically change to new trade settings

 

I am using MT4 with both an EA and a Signal. When there is a new trade the S/L and T/P settings for existing trades automatically change to new trade settings. This means if the price has changed that the trade can close at a loss. Is there anything I can do to prevent this. At the moment I have to manually keep monitoring and changing the settings and I have made a few big losses because of this.

 
check your strategy code, if you have something like this "extern bool ReplaceExistingOrders = true" and this is add to open position, it can be reason your problem. Greg
 

I would not recommend signal and EA running together.

You need to be very sure your EA does not interfere with the signal trades
