Dingo did you read the new ReadMe ? Should be possible. Or am I missing
something in this conversation ...
Version 5.00 brings hundreds of improvements including
a.. New Watchlist system featuring:
a.. unlimited number of watch lists
b.. lists keep original order in which symbols were added (still can be
sorted alphabetically on-demand)
c.. new AFL function to refer to watch lists by name
Regards, Ton.

Yes but how about his question on how to create a watchlist using AFL for >
64 watchlists?

Hello,
This statement from the AB guide is obsolete. Will be removed.
There is NO limit on number of watchlists and NO limit in Category*
functions.
Best regards,

Subject: RE: [amibroker] Creating new watchlists from AFL
Dingo,
Suppose I want to create a new style watchlist titled
"GuppyCountBackLine".
The CategoryAddSymbol appears to be limited to a range of 0..63 for
watchlists. (page 398 of 5.0 user's guide).
All of the watchlists I want to create fall outside of the default range
of 0..63.
The only way I see to create these watchlists is to manually create these
with the Symbol menu from the main toolbar. How do I create these new style
watchlists with just AFL? How do I delete the new style watchlists using just
AFL?
I do have code for the default case of 1..63. For example:
// ClearWatchList
function ClearWatchlist(wl)
{
if (Status("stocknum") == 0)
{
// remove all existing symbols from the market list
_TRACE("Removing Tickers from watchlist number " +
NumToStr(wl, 1.0)+":");
List = CategoryGetSymbols(categoryWatchlist, wl);
for( i = 0; ( sym = StrExtract( List, i ) ) != ""; i++ )
{
_TRACE(sym);
CategoryRemoveSymbol(sym, categoryWatchlist, wl);
}
_TRACE("Removing Tickers from Watchlist completed.");
};
}
This works great for 1..63 but it still appears that manually using
SYMBOL..WATCHLIST..New Watchlist must be used to create the new style
watchlist. I do not see how to do the logical equivalent of
SYMBOL..WATCHLIST..New Watchlist strictly using AFL for the new style
watchlist. For distribution purposes, I would prefer to not have a client
have to manually enter potentially hundreds of watchlist names using the Symbol
menu.
If you try using the wl = CategoryFind
("GuppyCountBackLine",categoryWatchlist) you get a -1 return code according to
debugview instead of the next available ordinal index number. Obviously, the
CategoryFind function is used to retrieve the ordinal number of the watchlist
for parameter entry into the other Category... functions in AFL.
Thanks in advance :^))

All of the old methods of creating watchlists remain - Check
CategoryAddSymbol/ ..removesymbol in the help file and then do a search of this
forum on them. There you'll find examples.

I do not see a way to create new watchlists using AFL. Is this
do-able? I have heard that you can code a workaround using FSO (file system
object) and something about maintaining the index yourself. Unfortunately, I
did not see any code posted. It seems this would be best done by TJ so the
implementation of watchlists would not be broken in case additional
enhancements were made. Also, the ability to delete a watchlist is needed from
AFL so that you do not have to predict ahead of time which watchlists need to
be created.
