This is a cross-platform МТ45 Expert Advisor – EA MetaTrader 5

Trading Strategy

After a losing trade, the МТ45 EA opens the next trade with a higher lot.

The first deal is always a Buy operation, after that positions alternate, i.e. buying-selling-buying.

The EA opens positions at the candlestick opening.

After a Stop Loss, the EA increases the lot by KL coefficient until it reaches the maximum value of ML. Then the lot is reset to the initial one, LТ.

EURUSD, the Н1 timeframe. The EA is optimized at an interval of 11.01.2014-09.09.2017

Features

The cross-platform mode is implemented using preprocessor directives. An example of the Martingale function:

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
double Lot()
  {
   double lot=LT;
//---  MQL4
#ifdef __MQL4__
   if(OrderSelect(OrdersHistoryTotal()-1,SELECT_BY_POS,MODE_HISTORY))
     {
      if(OrderProfit()>0) lot=LT;
      if(OrderProfit()<0) lot=OrderLots()*KL;
     }
#endif

//---  MQL5
#ifdef __MQL5__
   if(HistorySelect(0,TimeCurrent()))
     {
      double profit=HistoryDealGetDouble(HistoryDealGetTicket(HistoryDealsTotal()-1),DEAL_PROFIT);
      double LastLot=HHistoryDealGetDouble(HistoryDealGetTicket(HistoryDealsTotal()-1),DEAL_VOLUME);
      if(profit>0) lot=LT;
      if(profit<0) lot=LastLot*KL;
     }
#endif

   if(lot>ML)lot=LT;
   return(lot);
  }
