OrderProfit() result value abnormality.

[woohaeng heo]

This is a phenomenon that occurs occasionally.

The profit in the results window is -12.02, but when printed from the source, it comes out as -8.84.

[Code]

     for (int i = OrdersHistoryTotal() - 1; i >= 0; i--) {

         if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY) == false) continue;

         if (OrderSymbol() == Symbol() && (OrderMagicNumber() == MAGIC_NUMBER || OrderMagicNumber() == MAGIC_NUMBER + 1)) {

            trade.totalLoss += OrderProfit();

            Print(OrdersHistoryTotal(), "-", i, " ", OrderProfit(), " ", trade.totalLoss);

         }

      }

trade.totalLoss += OrderProfit() + OrderCommission() + OrderSwap();

Why do you call this a loss ("totalLoss")? It can also be a profit😄

[Vladislav Boyko]

Let's call it a little differently:

double orderProfit = OrderProfit() + OrderCommission() + OrderSwap();

Then you can add it to whatever you want😄:

double orderProfit = OrderProfit() + OrderCommission() + OrderSwap();
trade.totalLoss += orderProfit;

Although, you probably mean something like this:

double orderProfit = OrderProfit() + OrderCommission() + OrderSwap();
if(orderProfit < 0.0)
   trade.totalLoss += orderProfit;
else trade.totalWin += orderProfit;

Well, you get the idea: you do not take into account commission and swap

It comes out right after adding the fee and swap.

Thank you for your detailed answer.

The actual usage source is as follows:

      for (int i = OrdersHistoryTotal() - 1; i >= 0; i--) {
         if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY) == false) continue;
         if (OrderSymbol() == Symbol() && (OrderMagicNumber() == MAGIC_NUMBER || OrderMagicNumber() == MAGIC_NUMBER + 1)) {
            trade.totalLoss += OrderProfit();

            Print(OrdersHistoryTotal(), "-", i, " ", OrderProfit(), " ", trade.totalLoss);

            if (OrderMagicNumber() == MAGIC_NUMBER) break;
         }
      }

I removed the code to print the log.

This is to calculate the previous loss when applying martingale.
