Agree these functions would be useful, I use similar functions I've
written in AFL already. I have these and many other functions I've
written all in one AFL called AP_Functions.AFL. I just include -
#include "afl/AP_Functions.afl";
at the beginning of all my AFLs and then have easy access to all my
personal functions. Currently I use the free ABtool to fill in the
gaps. I will add Tomasz's script to my AP_Functions.AFL, if someone
has a script to clear a watchlist, could they share it. That would
enable pure AFL solutions to handle all my AFL based Watchlist
manipulations

function WL_Count(WatchListNum)

i=-1;
List = GetCategorySymbols( categoryWatchlist, WatchlistNum);
for (j=0; (sTicker = StrExtract (List , j)) !=""; j++ )

i = i+1;
}
return i;

{
if( Ticker == sTicker) {result = 1;}
}
return result;
}
