I think you will get new insight after these experience,I got the error "Not enough money" (screenshot). After that, the adviser forgot about the open orders for GBPUSD. The profit was almost $ 100, but the advisor does nothing. EA stopped trading GBPUSD after an error, do not close old ones and do not open new ones. EURUSD without such error, works well

not enough money to open trades because margin level not allow to open new order
might because using too high lot size or using low leverage
