I couldn't agree MORE ...
Rather than having steady monthly income, one is much more likely to
have unending daily headaches ... There are organizations much larger
than that of AmiBroker that have trouble getting this right for one
segment, let alone trying to get it right for stocks, mf's, futures,
currencies etc etc.

FastTrack and QuotesPlus. As I'm sure you've experienced it is a
manpower intensive job with so much opportunities for "oh sh_ts"

Friday night and Sat morning hand fixes; server outages, database
changes, etc. ; and selfishly speaking it would dilute the support in
both existing and new functionality in AB.

TC2K and Wordens are very good about keeping their DB current with
regards to tickers. BTW, Nirvana Systems( OmniTrader ) has just come
out with their new OmniData/OmniScan combo in OT2006, which also uses
Media General sectors/industries like TC2K - maybe TJ should
seriously consider offering "AmiData" 8 - ) I'm sure he would
be just as capable as anyone of buying wholesale data and repackaging
for it for retail. It might be a nice steady monthly income, could be
stored right in AB's native DB for optimal speed, would include
fundamentals for those that like them, etc.

if and when the time comes !

I use QP3. I like it and think that they provide a good product for
the price. However, some of their data is not as clean as I'd like.

expanded it. It does a fair amount (see below) and improves the
quality of my data. Although I use QP3 for data, the script is NOT
specific to a particular data source. Since it operates only on the
AB database, it should work with any data source or vendor.

share it with this group IF three people will step forward and be
willing to test it. (Since it deletes symbols, it has to be
clean.) Note that I do NOT want you to test it on a live AB
database, only a test AB database.

clutering up my database. I am not interested in the thousands of
Mutual Funds, Preferred Stocks, Unit, and some other non-stock
symbols. But, I am interested in a handful of Mutual fund symbols
(about 30-40), stocks, ETFs and some Indexes.

including certain groups. So all Mutual Fund (a Group) symbols are
deleted UNLESS they are in the "Always Keep" list. OTOH, QP contains
some old, unused symbols like the "LE**" symbols which are NOT in
a "Delete" Group but I still want to delete them. These are listed in
the "Always Delete" list.
>
> Before testing it this morning, I downloaded 29,000 symbols
from QP into an AB test database. This included Stocks, Indexes,
Sector/Industry assignments and Mutual Funds. After running the
script, 21,000 were deleted.
