Tomasz,
This helps. Two additional questions:
1) How are the symbols categorized into AB Groups such as ETFs,
ADRs, etc? Using the Issue Type?
2) It looks like IssueType is useful for me, but it is an integer.
Can you provide a mapping list of IssueType Integers to IssueType
Descriptions? Maybe a pointer to the AB or QP website that has this
mapping?
Thanks and regards,
Dan.

I still got Mutual Funds symbols. Why are they retrieved?
Shouldn't they be excluded?

TeleChart had some advantages. The TC charting had a few, minor

compared to Quotes Plus - Media General Industry Group and Sector
Indexes, intraday data updates, and clean data (minimal dead
tickers).

Hemscott's Media General industry/sector hierarchy doesn't work well
for me. TC stripped off the Hemscott macroeconomic Sector Level (8
Sectors) of the hierarchy and uses the bottom two levels of the
Hemscott hierarchy - Business Segment and Industry Group.
Unfortunately, TC refers to the "Business Segment" level as
the "Sector" level. IMO, the 31 TC "Sectors" provide too much
granularity and are not useful as macroeconomic indicators.

Using "AddToComposite" I can create custom indexes that meet my
needs and do not have to depend on the TC definition.

little additional data to AB other than price and volume. Quotes
Plus has a wide variety of fundamental data and "other" data. For
example, it provides market cap data and the percent shares held by
institutions - which I use in my system.

Accessing TC's data from AB is slower than accessing QP data. I
haven't quantified how fast the scans run, but scans running against
QP data appear to run 50 to 100% faster.

trainers seem like pretty good folks, asking a basic question to TC
management get a marketing hype response. In some cases, the
answers are quite insulting. At one point, I posted a question on
forum about the Worden Studio product (a web-based product) and how
it related to Telechart. Instead of a clear answer, I got
marketing hype. When I complained that I couldn't see any value
with Worden Studio, they condescendingly stated that I just didn't
know how to use it!

explain away their products' deficiencies by telling me that I just
don't know how to use it is extremely insulting! What's worse is
that it displays a lack of sensitivity for customer needs and
requirements.
