Try this afl.........!

Hellow.....guys! i have found this indicator by searching any wabsit.
here is afl,try this.
_SECTION_BEGIN("Asish_indicator_01");

a = Param("Angle",30,15,45,1);
pd = Param("Period",5,4,6,1);
P = ParamField("Price field",3);

a= (22/7)*(a/180);
Num = 0;
Den = 0;

for(i=1; i<=pd; i++)
{
if(pd%2==0 AND i > pd/2) X = sin((i-1)*a);
else X = sin(i*a);

Num = Num + X*Ref(P,1-i);
Den = Den + X;
}

if (den!=0) j1 = Num / Den;

Plot(j1,"j1",IIf(j1 > Ref(j1,-1),colorGreen,colorRed),styleThick);

Buy = Close > j1;
Sell = Close < j1;
Buy=ExRem(Buy,Sell); Sell=ExRem(Sell,Buy);
PlotShapes( shapeHollowUpArrow* Buy , colorGreen ,0);
PlotShapes( shapeHollowDownArrow* Sell, colorRed ,0);
//Plot(0,"",colorDarkBlue,styleLine);

Filter = Buy OR Sell;
Buy=ExRem(Buy,Sell); Sell=ExRem(Sell,Buy);
AddTextColumn(FullName(),"Name");
AddColumn( Buy, "BUY" );
AddColumn( Sell, "SELL" );


_SECTION_END();

_SECTION_BEGIN("Price1");
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
_SECTION_END();
SetChartBkGradientFill( ParamColor("BgTop", ColorRGB( 172,172,172 )),

ParamColor("BgBottom", ColorRGB( 172,172,172 )),ParamColor("titleblock",ColorRGB( 172,172,172 )));

Have you convinced yourself that this is a good system? If so, what market and setting are you using? Checking several markets the best profit that I see (with and without stops and varying the angle and period) is minimal at best.

Plenty of BUY/SELL signals within 1 Rs for Quotes like HDFC, HEROHONDA,
