How to calculate total PnL in mql5

[yomadestephens]

Hi there, any one can help with a well detailed code to calculate total profit and loss including swap and commission. Help will be much appreciated.

//+------------------------------------------------------------------+
//| Calculate proftis and losses of the day                          |
//+------------------------------------------------------------------+
double PnL()
   {
    HistorySelect(TimeCurrent() - PERIOD_D1, TimeCurrent());

    double PnL = 0;

    for(int i = 0; i < HistoryDealsTotal(); i++)
       {
        if(HistoryDealGetTicket(i) > 0)
           {
            if(HistoryDealGetInteger(HistoryDealGetTicket(i), DEAL_ENTRY) == DEAL_ENTRY_OUT)
               {
                PnL += HistoryDealGetDouble(HistoryDealGetTicket(i), DEAL_PROFIT);
               }
           }
       }
    return (PnL);
   }

Current time minus a few seconds is nonsense.

1. If you want the last twenty-four (24) hours, you need:

   HistorySelect(TimeCurrent() - PeriodSeconds(PERIOD_D1), TimeCurrent());
   

2. If you want the current day, you need:

   HistorySelect(date(), TimeCurrent());

Oh yeah, right! My bad, thanks for pointing that out. Wrote it in a jif.

How about just:

HistorySelect(iTime(Symbol(), PERIOD_D1, 0), TimeCurrent());

Would return the actual current date PnL.
