You CAN do something like this: (Psuedo code)
Watchlistnbr = param(...);
// retrieve comma-separated list of symbols in watch list
list = GetCategorySymbols( categoryWatchlist, Watchlistnbr );
// get one symbol at a time and process using your "system"
for( i = 0; ( sym = StrExtract( list, i ) ) != ""; i++ )
{
SetForeign(Sym..)
Your formula here
}
you would run this against a single ticker but it would process your
watchlist.
