Hello,
Most possible reason is you did NOT download all history at once today,
but downloaded
some months/years ago, then downloaded some later, then later then later.
Since then Yahoo may have added adjustments (for dividiends for example)
and this has changed HISTORICAL data on Yahoo.
AmiBroker data stored in local database remained the same (because you did not re-download
entire history again).
Suggestion: from time to time run FULL download to get adjustments.
Once you do you will get perfect match.
Best regards,
Tomasz Janeczko
