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
