Post subject:  Martingale 1.1.2.4, 1.1.3.3
Anyone have any idea how to do this?

Rather than multiply by 2 or 3, 1.2.4.8 or 1.3.6.12

1,1,2,4 or 1,1,3,3, works only when you have a better R:R than 1:1.

Lets say you have a R:R of 1:2, and your first order is 1 lot. If you lost, your second order could be 1 too, and if you win, you would make profit even covering the 1st loss.

And I'm doing backtesting in White Box Slope using tick data of 99% truefx modeling.

So far backtesting 4 pairs in all they gave between 70-80% hit rate and it looks like 1.1.2.4 or 1.1.3.3 would very sure

I expect a code to add this function I only consequi and martingale default 1.2.4.8.

Code: Select all

double CalculateLotSize()
{
   //Calculate Martingale lot size

   if (!UseMartingale) return(Lot);
   
   
   //Find most recent trade
   if (OrdersHistoryTotal() == 0) return(Lot);
   double SendLots = Lot;
   
   for (int cc = OrdersHistoryTotal() - 1; cc >= 0; cc--)
   {
      if (!OrderSelect(cc, SELECT_BY_POS, MODE_HISTORY) ) continue;
      if (OrderSymbol() != Symbol() ) continue;
      if (OrderMagicNumber() != MagicNumber) continue;
      if (OrderProfit() < 0)
      {
         double LotStep = MarketInfo(Symbol(),MODE_LOTSTEP);
         double digit = 0;
         if (LotStep == 0.1) digit = 1;
         if (LotStep == 0.01) digit = 2;
         SendLots = NormalizeDouble(OrderLots() * MartingaleLotMultiplier, digit);         
      }//if (OrderProfit() < 0)
      break;
   
   }//for (int cc = OrdersHistoryTotal() - 1; cc >= 0; cc--)
   
   //Check maximum lots allowed filter in the Martingale section
   if (SendLots > MaxLotsAllowed) SendLots = Lot;
   
   return(SendLots);

}//double CalculateLotSize(double price1, double price1)
