I'm happy with Quotes Plus and prior to
switching I had been a Telechart user. I went to QP3
for price/performance reasons(get both mutual funds
and stocks at same price point)
and the market breadth data,
something our group uses in signal generation.
Telechart has a bastardized system of
representing breadth data , where QP3 will provide the standard high/low, adv/decl
and up/down vol for each market. NYSE,
NASDAQ and ASX
I have to gen it as
composites for the Russell, NDX and NYSE operating companies, but not for
the main markets, .
Note the GetExtraData gets you only 2
arrays, the other GetExtraData elements are not historical but single bar
data.
I use it in my displays for fundamental and technical data, in a manner like
IBD does. For example in one chart display, I'll show the
technical
data - Price, RS, slope of
regression line, standard error of RS, UPI, StdDev of Price, then
from QP3 EPS Rank, QRS percentile,
Return on Equity, EPS Growth, and EPS
projected for 1 year.
QP3 is favored by TJ and the DLL
is significantly faster. There were a few welll written
comparisons last year and
you might hit on them if you search
Purebytes.com for this topic.
Adjusting the data, well that's a different
story for end of year distribution in the mutual fund area. They will adjust and
have
handled ticker symbol changes when called to
their attention. In the mutual fund ticker name change they handled it
better than one of
their competitors, kept the old name as
an alias.
Best regards
JOE

Subject: [amibroker] Quotes Plus Data in
AmiBroker
Hi,
I currently use Telechart Data. The good news is that the
data seems pretty clean, it is managed historically and it seems to have a
good Sector/Industry hierarchy with Sector and Industry composite
symbols. The bad news is that the Telechart database is supposed to
be slower and only two fields are exposed to AB in the Telechart API.
So, I'm considering switching to Quotes Plus. I'm seeking
feedback...
- Generally, how has your experience been? Happy?
Unhappy? Would you choose them again?
- Is the EOD data managed historically? I.e., when a split occurs,
is it handled correctly? Do you have to manage the data
yourself?
- Regarding Sector and Industry hierarchies, from the website, it looks
like they have sector and industry data. But...
--- Are all symbols in QP3 mapped to an Industry?
--- Are all Industries mapped to a Sector?
--- Does QP3 provide composite Sector Industry symbols that can be
scanned and charted like any other symbol?
--- In AB, can you scan for all symbols for a chosen Sector or
Industry?
--- Are there any QP3 Sector/Industry limitations compared to
Telechart?
- On the QP website, it says that they provide 200 data elements besides
price and volume (EPS, PEG, % Institutional ownership, etc.). However,
on the AB "GETEXTRADATA" function page, it only lists about 25 data elements
that can be retrieved. Does the "GETEXTRADATA" page not reflect
the changes in QP3? Are there QP data elements not exposed in the
API?
Thanks in advance for your feedback.
Best regards,
Dan.
