There's no processing of individual symnbols needed ...
Simply running AFL like what's below will clear a WL ...
TargetWL = 11;
List = CategoryGetSymbols(categoryWatchlist, TargetWL);
for(i = 0; (Symbol = StrExtract(List, i)) != ""; i++)
{
CategoryRemoveSymbol(Symbol, categoryWatchlist, TargetWL);
}
Buy = Sell = Short = Cover = 0;
If you want to see that it's cleared after the fact ehn you can
add ...
AB = CreateObject("Broker.Application");
AB.RefreshAll();
