Hello Wilco.
Yes, AQ uses the most recent date for lists of over 50 symbols.
There is no system to verify data as such except to watch the
download for time outs and errors.
Any time out and errors can lead to holes in the data at later
downloads.
You can use explore to find the last dates of data in your symbol
lists and then manually set the download to start (from date) for
the biggest gap.
With overwrite selected in AQ settings this will backfill all data
to your from date for all symbols.
You can post your suggestions for AQ improvements to the feedback
centre forum at the Ami website.
Also refer to posts on /amiQuote at the EOD topic.
The read me file for AQ and the AB help>tutorial>updating
quotes>AmiBroker is also useful.
Brian.
