EA multiple chart other pair interference

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);

     }
