Hello,
It was discussed dozen of times and all. The fact that you
have given symbol
in RT quote list does not mean you have historical data. RT
quote displays
only current quotes (no history).
If you want to have history saved in local database you need
to
a) setup IQFeed as shown in the
video:
b) access every symbol you want to have history by
either
displaying its chart, or running
scan/exploration/backtest.
No matter how given symbol data is accessed it will trigger
backfill
and get history from IQFeed.
Once data are obtained from IQFeed, it will be saved in local
database
provided that "Local data storage" is set to "ENABLED" as in
the video.
If you are using AA to access data, make sure to run at least
one scan
with "wait for backfill" turned ON. This is essential as
it guarantees that AmiBroker waits
for IQFeed to respond with backfill data. It usually takes few
seconds for IQFeed to
respond for every backfill request.
Otherwise AB will scan orders of
magnitude faster than IQFeed is able to respond and you won't get data for
all symbols.
The backfill procedure does NOT differ, it is the same for
QCollector and AB
(request -> wait -> IQFeed responds - transfer the data
- save).
Best
regards,
Tomasz Janeczko

They told me the same thing. Try to contact their support
and tell them exactly what is the problem and be sure you installed everything
fine with AB.

Here is DTN's response:
Hello Tim, with saving data onto your
computer it is actually up to AB
or any other 3rd party software to do so
not IQFeed. With IQFeed we
provide the raw data from our quote servers
and the historical data
which is saved on our end then when you request
the data, it will sent
to you. I believe that there is a way to save the
data within AB but
not 100% sure how, so your best bet would be to
contact AB Support to
know for sure.
Thanks.
