you have to define the SAR function, see code
below, regards, Ed
accel = Param("Acceleration", 0.02, 0, 1, 0.001);
mx = Param("Max.
acceleration", 0.2, 0, 1, 0.001);
f_sar = SAR(accel,mx);
colordots = IIf(f_sar < L,colorBrightGreen,IIf(f_sar > H,colorRed,colorWhite));
Buy = Cross(C,f_sar); Buy = Ref(Buy,-1); BuyPrice = O;
Sell = Cross(f_sar,C); Sell = Ref(Sell,-1); SellPrice = O;
SetBarsRequired(-2,-2);
SetChartOptions(0,
chartShowDates);
Plot(C,"\nClose",colorWhite,64);
Plot(f_sar,"\nf_sar",colordots,styleDots|styleNoLine);
PlotShapes(IIf(Buy,shapeUpArrow,shapeNone),colorGreen,0,L,-15);
PlotShapes(IIf(Buy,shapeHollowUpArrow,shapeNone),colorWhite,0,L,-15);
PlotShapes(IIf(Buy,shapeHollowSmallCircle,shapeNone),colorWhite,0,BuyPrice,0);
PlotShapes(IIf(Sell,shapeDownArrow,shapeNone),colorRed,0,H,-15);
PlotShapes(IIf(Sell,shapeHollowDownArrow,shapeNone),colorWhite,0,H,-15);
PlotShapes(IIf(Sell,shapeHollowSmallCircle,shapeNone),colorWhite,0,SellPrice,0);
