New comment
 
I want to delete a pending order at specified time, but always getting error in MetaEditor5

void DeletePendingOrders()
  {
   for (int i = OrdersTotal() - 1; i >= 0; i--)
     {
      if (OrderSelect(i,SELECT_BY_POS))
        {
         int orderType = (int)OrderGetInteger(ORDER_TYPE);
         if (orderType == ORDER_TYPE_BUY_STOP || orderType == ORDER_TYPE_SELL_STOP)
           {
            ulong ticket = OrderGetTicket();
            if (!trade.OrderDelete(ticket))
              {
               Print("Error deleting pending order: ", GetLastError());
              }
            else
              {
               Print("Pending order deleted: ", ticket);
              }
           }
        }
     }
  }

Error: 
'SELECT_BY_POS' - undeclared identifier
'OrderSelect' - wrong parameters count
'OrderGetTicket' - wrong parameters count

  2. You know what the problem is, now read the documentation and learn MT5. Your posted code is mostly MT4.

  3. There is no need to create pending orders in code.

    1. The pending has the slight advantage, A) you are closer to the top of the queue (filled quicker), B) there's no round trip network delay (filled quicker.)

      Don't worry about it unless you're scalping M1 or trading news.

    2. Humans can't watch the screen 24/7, so they use pending orders; EAs can, so no need for pending orders, have it wait until the market reaches the trigger price and just open an order.
