Glenn,
You could create a function and place it in Indicator builder and see it on
the fly...without creating the composites....
This gives the same percent :
adv=C > Ref(C,-1);
decl=C <= Ref(C,-1);
AddToComposite(adv,"~adv","x");
AddToComposite(decl,"~decl","x");
Buy=0;
perc_Adv = Foreign("~Adv", "x") / ( Foreign("~Adv", "x") + Foreign
("~Decl", "x") ) * 100;
Filter=1;
AddColumn(perc_adv,"%Adv",1);
AS THIS, in Indicator Builder:
//Function
//% of stocks Advancing
Wlist=Param("WatchListNum",0,0,63,1);
function CreatePercentofStocksAdvancing( listnum )
{
// retrive comma-separated list of symbols in watch list
list = GetCategorySymbols( categoryWatchlist, listnum );
Advancers = 0; // just in case there are no watch list members
for( i = 0; ( sym = StrExtract( list, i ) ) != ""; i++ )
{
f = Foreign( sym, "c" ) > Ref(Foreign( sym, "c" ),-1) ;
if( i == 0 ) Advancers = f;
else Advancers = Advancers + f;
}
return (Advancers / i)*100; // divide by number of components
}
Plot( CreatePercentofStocksAdvancing( Wlist ), "% of Stocks Advancing",
colorGreen );
