orderSend（）时是否可以显示实际的滑点

Question

对于MT4，MQL

当sendOrder()时，

有时成功或失败有时主要是由于打滑。

我想在sendOrder()时获得真实的滑点。

有可能吗？

我现在的源代码如下。

     Ticket = OrderSend(_Symbol,OP_SELL, Lot,Bid,2, // '2' is slippage alloable limit.
     SL,TP,comment,Magic);

     if (Ticket > 0){
       // if slippage is under 2 it works.
       // want to check the real slippage
     }
     else {
        int err = GetLastError();
        if(err == ERR_NO_ERROR || 
           err == ERR_COMMON_ERROR ||
           err == ERR_SERVER_BUSY ||
           err == ERR_NO_CONNECTION ||
           err == ERR_TRADE_TIMEOUT ||
           err == ERR_INVALID_PRICE ||
           err == ERR_PRICE_CHANGED ||
           err == ERR_OFF_QUOTES ||
           err == ERR_BROKER_BUSY ||
           err == ERR_REQUOTE ||
           err == ERR_TRADE_CONTEXT_BUSY){
             //want to check the slippage here!!!
        }

     }

您必须通过与订单一起发送的价格减去OrderOpenPrice来自行计算滑点。

示例：

   double price = Bid;
   double slippage = 0.0;
   int ticket = OrderSend(_Symbol, OP_SELL, Lot, price, 2, SL, TP, comment, Magic);
   if(OrderSelect(ticket, SELECT_BY_TICKET))
      slippage = int(NormalizeDouble(fabs(price - OrderOpenPrice()) / _Point, 0));
