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

Will be removed. There is NO limit on number of watchlists and NO limit in Category* functions.

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.

There you'll find examples. d _____ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of RR Sent: Tuesday, September 11, 2007 10:48 PM To: [email protected] Subject: [amibroker] Creating new watchlists from AFL 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.
