<FONT face=Arial color=#0000ff

from the exchanges that way and is out of their control. The
difference between vendors (IMO) comes from the effort they put into
cleaning up the data. CSI sends out thousands of data
corrections every day, some going back 10, 15 even 20 years. I
report data errors to CSI and they get fixed and distributed the next
day. Many other serious users do the same. Whether
any of those changes are processed by Yahoo... who
knows?

It
appears that corrections do find their way into Yahoo (one day it is wrong
and the next it is right). The main differences, as far as I can tell,
between Yahoo and being a CSI subscriber (as I was once) is (1) Yahoo's
historical servers appear to lag by 2-3 hours vis-a-vis CSI's, (2) if
something is wrong there is essentially nobody to talk to, (3) CSI's servers
might have somewhat better "up time" statistics, but I have had very little
problem with Yahoo. As for the lag in historical data, I download
current (supplied by Reuters which Futures rated 2nd only to CSI) shortly
after the market closes and then overwrite with historical on the
weekend. There is rarely any difference between the two. Have
been off CSI for about 3 years, downloading from Yahoo directly into
Metastock format without any real problems. No speculation, just
my experience.

I have been reading that Yahoo's historical data
comes from CSI and Chuck Rademacher has said that CSI is his main source
of data. Does CSI
have several different groups of historical data, some of which is not
back adjusted and dirty, that they sell to Yahoo? Below, I have
copied on of Chuck's comments about CSI data.
CSI has the advantage of having backadjusted
and actual prices. IMO, their data is also much
cleaner.
Rik, perhaps you mean that the Yahoo servers
are not the most reliable when you say that
Yahoo certainly is not the best source of data. Ron D
