["John" <jea55129@xxxxxxxxx>]

George,

I changed the formula around so you can adjust the parameters

Length= Param("Length",10,2,30,2);
StdDevUp= Param("Stdev",2,1,20,0.5);
UpBand=BBandTop(H,Length,StdDevUp);

//StdDevDn= 2;
DnBand=BBandBot(L,Length,StdDevUp);


Buy=C>UpBand;
Sell=Close < MA(Close,Length);
Short=Close < DnBand;
Cover=Close > MA(Close,Length);
Buy=ExRem(Buy,Sell);
Sell=ExRem(Sell,Buy);
Short=ExRem(Short,Cover);
Cover=ExRem(Cover,Short);
Plot(C,"",1,64);
Plot(UpBand,"",2,1);
Plot(DnBand,"",3,1); 
PlotShapes(IIf(Buy,shapeUpArrow,shapeNone) ,colorBrightGreen,0);
PlotShapes(IIf(Sell,shapeDownArrow,shapeNone),colorRed,0);
PlotShapes(IIf(Short,shapeDownArrow,shapeNone),colorOrange,0);
PlotShapes(IIf(Cover,shapeUpArrow,shapeNone) ,colorBlue,0);


I don't do BB's. Not sure what you are asking about with the %b?

Happy Holidays!

John
