Hello Triangle702000,
Possibly due to default behaviour of AutoUpdate (I think sometimes
programmers have to choose between the devil and the deep blue sea).
To get the max out of AQ we are better off to dig in a bit - Tomasz
always leaves us an escape hatch.
In this case Tomasz chose to use the end date of the first symbol as
the default start date for auto download i.e. it is an updater and
assumes we start with clean data, have an index as the first symbol
(indexes will always trade) and that we constantly update (keep
building the database).
Try this (for specific range downloads_:
a)open AQ
b) get ticker list from AB (use the AQ menus)
c) set date range in AQ
d) download with auto import to AB
(this downloads the range and forces the data to AB).
In Database Management at the UKB my first two posts seem rather
boring and mundane but they actually point to all, or most, of the
significant nuances found in AmiQuote basic use.
>From memory, this one, and maybe the one before it, make the
distinction between autoupdate and range downloading via AQ.
hope that solves it for you.

(for backtesting I recommend one range download in one day - deep
history - don't add to it after that - quarantine it.
For live or paper trading - keep a shorter database - start it as a
range download and auto upadate thereafter - dump it every month and
start again (Yahoo history will change due to updates and also
updating increases the risk of messing up the data).
hope that solves it for you.
