Hi guys!

I'm having a hard time with MAXLOTSIZE..

My broker does not allow Lots greater than 50.00. So, when my MM calculates a greater lot than 50 would give me error 131. I could "cheat it " assuming that if the lot is greater than 50 assume 50 as default as shown bellow.

What i Really would appreciate a help is to split the order about to be sent in as many as my margin and risk factor allows. Ex. 7 orders of 50 and 1 of 48 with a total of 8 orders.. instead of the static orders bellow..

Thanks a lot to you guys and may the pips be with you!

Thanks a lot! I couldn´t make it on my code.. here it goes.. thanks for the help..



double LotSize() {
   double Lot;
   double LotOptimized;
   double lotstep;
   double marginrequired;
  
   if (RiskPercent > 0 && UseMM) {
   
      lotstep = MarketInfo(Symbol(), MODE_LOTSTEP);
      marginrequired = MarketInfo(Symbol(), MODE_MARGINREQUIRED);
      Lot = AccountBalance() * RiskPercent / 100.0 / marginrequired;
      
      LotOptimized = MathMod(Lot, lotstep);
      if (LotOptimized != 0.0) Lot -= LotOptimized;
   } else Lot = Lots;
   double minlot = MarketInfo(Symbol(), MODE_MINLOT);
   double maxlot = MarketInfo(Symbol(), MODE_MAXLOT);
   if (Lot < minlot) Lot = minlot;
   if (Lot > maxlot) Lot = maxlot;
   return (Lot);
