Hello Experts,

I am looking for some help in building a scanner to backtest my trading idea. This code is based on RMI indicator & it has 3 components -

- RMI
- Relative Momentum Index
- Weighted MA of Relative Momentum Index

I need to backtest my results with the following conditions -

Buy - When RMI(3,15) is above 60 AND Relative Momentum Index crosses above 50 along with Weighted MA of Relative Momentum Index

Sell/Exit : Weighted MA of Relative Momentum Index closes below 50

Short - When RMI(3,15) is below 40 AND Relative Momentum Index crosses below 50 along with Weighted MA of Relative Momentum Index

Cover/Exit : Weighted MA of Relative Momentum Index closes above 50

Here is the code I use for your reference. Thanks a ton in advance.

```
Length=Param("Length?",1,2,60,1);//default =14 or 20
mom=Param("Momentum?",1,2,15,1);//default = 4 or 5
xRMI = RMI(Length,mom);
Plot(xRMI, " Relative Momentum Index ("+WriteVal(Length,1.0)+")", colorDarkBlue, 1 + styleThick);
_SECTION_END();
Plot(50,"",colorCustom11,styleLine, styleThick|styleNoLabel);//midline
Buy = Ref(xRMI,-1)<50 AND xRMI > Ref(xRMI,-1);
Sell = Ref(xRMI,-1)>50 AND xRMI < Ref(xRMI,-1);
Buy = ExRem(Buy,Sell);
Sell = ExRem(Sell,Buy);
PlotShapes( shapeUpArrow * Buy + shapeDownArrow * Sell, IIf( Buy, colorGreen, colorRed ) );
/*End Buy and Sell Conditions*/
_SECTION_BEGIN("RMI1");
periods = Param( "Periods", 20, 1, 200, 1 );
momentum = Param( "Momentum", 5, 1, 200, 1 );
Plot( RMI(periods, momentum) , _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
_SECTION_END();
//XXXXXXXXXXXXXXXXXXX EXPLORE XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
_SECTION_BEGIN("Weighted MA Color");
//SetChartBkColor( ColorHSB( 86, 36, 126 ) );
P = ParamField("Field");
Type = ParamList("Type", "Weighted,Lagless-21,Hull-26,Linear Regression-45,Exponential,Double Exponential,Tripple Exponential,Wilders,Simple");
Periods = Param("Periods", 9, 2, 100 );
Displacement = Param("Displacement", 1, -50, 50 );
m = 0;
if( Type == "Weighted" ) m= WMA( P, Periods );
if( Type == "Lagless-21" ) m= 2*EMA(P, Periods)-EMA(EMA(P, Periods), Periods);
if( Type == "Hull-26" ) m= WMA(2*(WMA(P, Periods/2))-WMA(P, Periods) ,4 );
if( Type == "Linear Regression-45" ) m= LinearReg( P, Periods );
if( Type == "Exponential" ) m = EMA( P, Periods );
if( Type == "Double Exponential" ) m = DEMA( P, Periods );
if( Type == "Tripple Exponential" ) m = TEMA( P, Periods );
if( Type == "Wilders" ) m = Wilders( P, Periods );
if( Type == "Simple" ) m = MA( P, Periods );
Linecolor = IIf( m > Ref( m, -1), ParamColor("UPColor", colorGreen), ParamColor("DOWNColor", colorRed) );
Plot( m, _DEFAULT_NAME(),Linecolor , styleThick, 0, 0, Displacement );
_SECTION_END();
```
