Tomasz,
My remark was a comment to Yahoo's statement ("Currently, our provider
supplies the data to two decimal places".)
I mean Yahoo financial site provides historical data for many markets. CSI
is their supplier for a few, not for all of them. But the 2 decimal places
precision problem is present everywhere. There is no difference between
Japan, EuroNext, USA ou Argentina.
So ? Do you think the Yahoo ASCII 2 decimal places price record format (O H
L C AdjV AdjC) is inherited from these different suppliers or so by Yahoo's
design ? Why the hell would all data suppliers bother providing Yahoo data
in this strange format ?
Either it was a Yahoo requirement.... or the raw data were transformed by
Yahoo to this format.
Cordially
Alain
