[amibroker] relative strenght of a list of shares against index

["rijnaars" <rijnaa@xxxxxxx>]

I need help on producing the outcome of this formula to a list.

I want to compare several shares against Dow Jones.

With this formula i am able to see the relative strenght of each 
individual share. This is indicated buy a number. I would like to be 
able to put this outcome in a list when i do a scan. 
I need some help to do that.

the formula is as follows:
 
_SECTION_BEGIN("Relative Performance");
_N( TickerList = ParamStr("Tickers", "^DJI,$INDU,") );
NumBars = 20;
fvb = Status("firstvisiblebar");
Plot( 100 * ( C - C[ fvb ] ) / C[ fvb ], Name(), colorBlue );
for( i = 0; ( symbol = StrExtract( TickerList, i ) ) != ""; i++ )
{
 fc = Foreign( symbol, "C" );

 if( ! IsNull( fc[ 0 ] ) )
 {
   Plot( 100 * ( fc - fc[ fvb ] )/ fc[ fvb ], symbol, 
colorLightOrange + ( (2*i) % 15 ), styleLine );
 }
}
PlotGrid( 0, colorYellow );
_N( Title = "{{NAME}} - Relative Performance [%]: {{VALUES}}" );
_SECTION_END();
