AW: Yahoo, data, etc.

["VK" <volker@xxxxxxxxxxxxxx>]

Yaroll.
Actually I am quite happy with the quality of the Yahoo data (US). On
top of that I can key in the symbol from nearly any exchange in the
world and get the historical data. Or I download the whole history of a
full portfolio at once and get it updated every day. No other data
vendor offers that!
With Yahoo you can also get RT price update for free. This is quite
handy if you have 50 stops to follow and want to know which one is
closest to your stop.

||Betreff: Yahoo, data, etc.
||
||Hello,
||
||Is there a free and more-or-less reliable source of EOD data on US
stocks?
||Nothing fancy, just Dow 30, Nasdaq 100.
||
||I downloaded the Yahoo data and converted to Metastock format, then
||checked
||it for consistency. I had hoped at least blue chips would be fine, but
the
||fact is, there's not one stock without errors. Most frequent is Error
1091
||(Large change in close, that's when the stock closes 20% or more off
the
||previous close). I guess most of this is due to splits, but surely not
||all.
||Information on splits probably is there somewhere, but it's still a
pain
||to
||go back in some cases 30 years back to adjust it all for +100 stocks.
||
||What do you think? I concluded Yahoo is a total mess. Maybe someone
would
||help out? I feel I'm the last Mohican to be interested in plain old
stocks
||:-))  Or please advise where to find EOD, split-adjusted data on
stocks.
||No
||need for updates, or recent data, for it's needed for historical
||backtesting
||only. Maybe even without Nasdaq 100, for I think just about all of
these
||had
||gone through this "startup company" phase relatively recently (in
years)
||while the Dow 30 had been around for a while (well, established
something
||like a decade or two, etc.) I'm not at all sure if startup companies
can
||be
||tested in the same category as blue chips (these latter shouldnt have
||these
||jumps in for example ATR or StDev).
||
||Thanks. Best regards
||
||Yarroll
