I have never found any bug with Nbarstop
ex below works perfectly
Buy= DayOfWeek()==5;
Sell=0;
BuyPrice= C ;
ApplyStop (stopTypeLoss, stopModePoint,2*ATR(10) ,True) ;
ApplyStop (stopTypeTrailing, stopModePoint, 20*ATR(10) ,True,False) ;
ApplyStop (stopTypeProfit, stopModePoint, 20*ATR(10) ,True,False) ;
ApplyStop(stopTypeNBar,stopModeBars,50);
Plot(Close,"close",colorBlack,64);
Equity(1);
PlotShapes(IIf(Buy,
shapeUpArrow,shapeNone),colorGreen,0,L,-20);
PlotShapes(IIf(Sell,
shapeDownArrow,shapeNone),colorRed,0,H,-20);
// StopLoss
Plot(ValueWhen(Buy,C+2*ATR(10)),"Profit",colorBlue,1);
Plot(ValueWhen(Buy,C-2*ATR(10)),"StopLoss",colorRed,1);
Plot(HighestSince(Buy,H)-ValueWhen(Buy,2*ATR(10)),"Trailing",colorGreen,1);:
