Edit an EA

Hello,
I would like to delete or disable an expression in my EA.
When my price "Level" is touching my EA opens an order, what I would like is that the order opens once
and then act as if the following expression "red box" is deactivated or deleted

      if(t>16384 && Ask ==Level && Level !=0)
        {
         ticet=OrderSend(Symbol(),OP_BUY,lots,Ask,3,Bid-StopLoss*Point,Ask+TakeProfit*Point,"a",magic,0,clrGreen);
        } 
      if(t<16384 && Bid ==Level && Level !=0)
        {
         ticet=OrderSend(Symbol(),OP_SELL,lots,Bid,3,Ask+StopLoss*Point,Bid-TakeProfit*Point,"a",magic,0,clrRed);
