/* QStick from Tushar Chande. This indicator measures intraday momentum by
using the distance between the open and close of price over "n periods".
It is set at the default ( 8 ) periods that Chande suggest. */

MaxGraph=3;

Graph0=MA( C-O,8);

// The '0' line.
Graph1=0;
Graph1Style=5;
Graph1Style=styleNoLabel;
_SECTION_END();

_SECTION_BEGIN("EMA");
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 200, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );

Plz help.. Thanx.

Hi Mansukh
Don't know much about the indicator...but can suggest you how to code that in Ami.
You first need to specify Buy and Sell variables based on crossovers....
Just include these few lines at the last of your code:

Buy=Cross(Graph0, Graph1);
Sell=Cross(Graph1, Graph0);

shape = Buy * shapeUpArrow + Sell * shapeDownArrow;
PlotShapes( shape, IIf( Buy, colorGreen, colorRed ), 0, IIf( Buy, Low, High ) );

GraphXSpace = 5;

Should work. Hope this helps.
Cheers
