Hi, i'm trying to recreate a EA to delete pending order when it hit the price i input. But kept having error. tried to google up  on the exact word that i should use" (???=My_Price_Target), but not able to. Or maybe the code i do is wrong? anyone could help please? thanks
int start()
{
if (Ask= My_Price_Target)
  if else (Bid=My_Price_Target)
   {
    for(i=OrdersTotal()-1;i>=0;i--)
       {
       OrderSelect(i, SELECT_BY_POS);
       int type   = OrderType();
               
       bool result = false;
              
       switch(type)
          {
            //Close pending orders
          case OP_BUYLIMIT  : result = OrderDelete( OrderTicket() );
