I know you are talking about COM, but for what it is worth, the
following AFL will erase a watch list and then fill it with the
Filtered symbols. It was derived from previous posts and also
with some help from support.
Filter = 1;
WatchListNumber= CategoryFind("Test", categoryWatchlist );
if( s = Status("stocknum") == 0 )
{
List = CategoryGetSymbols (categoryWatchlist,
WatchListNumber);
for(i = 0; (Symbol = StrExtract(List, i)) != ""; i++)
{
CategoryRemoveSymbol (Symbol, categoryWatchlist,
WatchListNumber);
}
}
if( LastValue (Filter))
{
CategoryAddSymbol( "", categoryWatchlist,
WatchListNumber);
}
When used in an Exploration (ie the code it not included in an
indicator afl) it works perfectly, but if the code is included
in an indicator, the running of an Exploration only fills the WL
with the currently selected symbol.
Hope this helps
