Dave,

Thanks for your reply.  I had forgotten that you could only assign a stock
to only one membership category.  What I would prefer to see is a new
category added and then the AB plug-in support to automatically convert any
TC2000 watch lists or QP lists available for direct use within AB.    

I prefer to stay out of the data maintenance (watch list name maintenance)
game as much as feasible.  Having a new category type similar to watchlists
would go a long ways towards reducing the need for hundreds of watch lists
especially when many of these watch lists may be relatively static like the
Component Watchlists, ETF component watchlists maintained by TC2000.

I see watch lists as providing different functionality than the component
lists as they are more dynamic while the component lists are more static in
nature.  Also, having a separate category would help novices like myself to
prevent overwriting results they want to keep. (Did I already use that
watchlist number???)

If I recall correctly, increasing the number of watch lists above 64
requires an internal AmiBroker database change so this would break backward
compatibility.

Thanks,


RR

Not sure why you want to use groups but did you know that any stock
can only be assigned to one group?

Per the help file:
-----------------------------------------------------------------
There are two types of categories:

with mutualy exclusive membership: groups, markets, sectors/industries
- it means that symbol must belong to single group, single market and
single sector/industry at a time. You can move the symbol from one
group/market/sector/industry to another but you can not remove this
assignment - you should create "Unassigned"
group/market/sector/industry instead and move 'unassigned' symbols there.

with free membership: watch lists/favorites/indexes- it means that a
symbol may belong to ANY number (including zero) of watch lists (and
to favorite/index category too). In this case you can remove this
assignment by Watch List->Remove

Watch lists are covered in detail in the User's Guide: Tutorial:
Working with Watch Lists. 

-----------------------------------------------------------

That is why I personally have made a request to increase the number of
watchlists from 64 to a higher number (256?).

You can comment on this (add your support) and make other suggestions
at:    http://www.amibroker.com/feedback/index.php

I would ask that in order to reduce duplicate requests that you do a
search prior to posting your suggestion.  It is better to comment on a
particular suggestion or bug.
