Hi,
I my experience it depends on the market. The US data (NASDAQ, Amex,
NYSE) is very good, but the European market seems not to be. For
example, the German markets have sometimes holes in the historical
data, OHLC looks really strange, or the last day is delayed. I don't
know about the Asian area ...
Best regards,
Markus
