RE: [amibroker] Script to manipulate WatchLists?

["Bob Jagow" <bjagow@xxxxxxxxxxxxxxx>]

Anthony,
This particular problem involved removing stale [old] entries from a Buy
list, which was initially populated manually from a tip service. I would
add dated comments to the symbol's notepad, and the list increased to >
80 symbols over a period of some months.
On perusing the list, some aging choices became of little interest over
time, so I added them manually to the 'stale' watchlist.
With eSignal, I need to reduce the # of symbols scanned and excluding
the 'stale' list will do, but I wanted to remove those symbols from the
buy list for aesthetic reasons.

The same sort of problem  arises in eSignal if you import a large list
and generate a desired subset via an exploration;  you can't exclude the
original list and my solution would require exporting the subset,
deleting the large list, then importing the subset.

My favorite program, TechnifilterPlus [now Aussie based], allows the
required Boolean comparisons between lists; might make sense to export
such lists and manipulate them in TF+.


Regards,
Bob

Bob,

I use the CategoryAddSymbols() ..etc functions....

How are you selecting symbols to be moved from one watchlist to another
?

  In my esignal DB, I want to move selected symbols from active
watchlists
  into a potentially large stale wList that can be excluded in AA.
  I'm currently doing it by a 4-step process** which is fast enuf, but
the
  downer is that the stale list won't auto backfill.

  Anyone tried moving symbols via CategoryGetSymbols(),
  CategoryRemoveSymbols(), CategoryAddSymbol(), inWatchList?

  Regards,
  Bob
  **-------
  1- Form the stale list via AA or manually [wList add symbol].
  2- Symbol=>Watchlist=>Export
  3- Symbol=>Cat Assign=> stale delete
  4-- Symbol=>Watchlist=>Import
