Ajay,
I have been playing around with the
formula, and I have it working in so far as I understand what you want. Take a
look at the AFL, and try it. Let me know if this is what you want, if not tell
me what it is not doing correctly.

Code Begins:
_SECTION_BEGIN("Colored
Bolinger Bands");
pr=Param( "Period",20,0,100,1);
P = ParamField("Price field",-1);
Style = ParamStyle("Style") | styleNoRescale | styleNoLabel
|styleDashed;
BBT=BBandTop(P,pr,2);
BBB=BBandBot(P,pr,2);
topcond = (Cross(BBT,C)OR
C>BBT)AND Ref(C, -1)> BBT;
botcond = ( Cross(C,BBB))AND
Ref(C, -1 <
BBB);
bbtcolor = IIf( BBT>
Ref (BBT, -1), colorGreen,colorRed );
bbbcolor = IIf( BBB
> Ref (BBB, -1), colorGreen,colorRed );
Plot( BBT, "BBTop" + _PARAM_VALUES(), bbtcolor, styleLine|styleThick
);
Plot( BBB, "BBBot" + _PARAM_VALUES(), bbbcolor, styleLine|styleThick
);
Buy=botcond;
Sell=topcond ;
//Buy=ExRem(Buy,Sell);
//Sell=ExRem(Sell,Buy);
PlotShapes(shapeUpArrow * Buy, colorGreen,
0, L, - 10);
PlotShapes(shapeDownArrow * Sell, colorRed,
0, H, - 10);
_SECTION_END();
Code Ends:
