I've been spending a bit more time with Quotes Plus - pretty good
data feed, but there are issues:
- No lists of the stocks making up S&P500 or other key indices
(they do have Nasdaq and NYSE). This means if you use the S&P, for
instance, for looking % of stocks above a moving average, you're going
to have to manage the lists yourself.
- Has fundamentals - this is useful, and the data feed can be used with
more fundamentally-oriented scanning software such as HGSI.
- Has a ton of indices - gold/silver/oil, etc as well as put/call
indices, etc. Premium may have the put/call as well - I'd have to take
a look.
On Premium Data:
- Fantastic folder breakdown of industries and indices. So, running a
scan over the stocks in the S&P 500 or the S&P 1500 is simple,
and will not require maintenance from you.
- Lacks some basic useful indices out of the box - like those mentioned
above (oil/gold/etc).
- No fundamental data.
- Great ETF breakdowns into different categories.
Telechart:
- Includes access to their online stock tool freestockcharts.com
- Includes fundamentals
- Lots of indices and special, TC-only indices like T2106 etc.
- Major problem - the API to access the data via AB doesn't adjust for
splits or dividends. This basically, from my point of view, makes it
useless for backtesting.
That's what I've got right now - to me it's a toss up between Quotes
Plus and Premium.
