EA multiple chart other pair interference

New comment
 

Hi,


What is the best method to stop interference when running EA on multiple pair? I'm getting wrong indicator from the wrong pair on my chart. Would something like below do the trick by using _Symbol == _Symbol ??

  if(BuySignal>=NumberOfSignal && _Symbol == _Symbol)
     {
      SellBuy(BuyAmount,AskPrice,AskStopLoss,AskTakeProfit,MaxPair,RandomSignal);
     
     }

   if(SellSignal>=NumberOfSignal && _Symbol == _Symbol)
     {
      SellBuy(BuyAmount,BidPrice,BidStopLoss,BidTakeProfit,MaxPair,RandomSignal);

     }
 

No that won't work.

Use a Magic Number.

Using OrdersTotal directly and/or no Magic number filtering on your OrderSelect loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

Thank you. What are we using instead of OrderMagicNumber() in mql5 ?
