extern int RiskFactor = 2.0; //Percent
extern double Lots = 0.1; //Manual Lots if Risk Factor=0

double lot_size() {
double lots;
double LotSize = MarketInfo(Symbol(), MODE_LOTSIZE);
double MinLot = MarketInfo(Symbol(), MODE_MINLOT);
double LotStep = MarketInfo(Symbol(), MODE_LOTSTEP);
if (RiskFactor==0) return (Lots);
lots = (AccountFreeMargin()* AccountLeverage() / LotSize) * RiskFactor/100.0;
if (lots < MinLot) lots = MinLot;
lots /= LotStep;
lots = NormalizeDouble(lots, 0);
lots *= LotStep;
return(lots);
}
