I use to lose data with IB. The non-problem is that sometimes when you save
the database, the collected data for that day or day(s) for a symbol(s) does
not get saved.
A while back there was a post that said before you save your database at the
end of the day, run a simple scan across all of yor symvols in the database.
Then save the database and exit. Ever since I added the scan I no longer
lose data. So, here is what I do:
1: Open AB in the morining along with TWS.
2. bacfill all RT symbols ( backfill set to 1 day).
3. Prior to shu down for the day, run a simple scan across all symbols in
the database.
4. Now save the database
5. exit AB and shut down TWS.

Subject: RE: [amibroker] IB Feed - AB does not collect and save data for
symbols only in the RTQ list.
Guys, it is really pretty simple to get this RT quote thing from IB
working.
1. A chart needs to be opened to collect RT quotes.
2. How to do that. If you have only a few symbols it is easy to select
the first symbol in the drop down box in the toolbar and then just hold down
the down arrow key to run through all the symbols. Then click on the RTQ
box (lower right) and click on backfill all selected symbols.
3. The alternative is to run a scan, any scan, for all symbols. That
opens them up for updating. Then click the backfill all in the RTQ box.
Sometimes you will have to wait for the current symbol to fill and then
the backfill all choice will become active and you can click it.
If you start the process before normal trading hours it will run quickly.
If you start it later in the day the data flow is slower and you might want
to go read your e-mail and when you return all the RT charts should have
updated. The charts will stay updated all day and if you save all before
exiting or disconnecting from IB everything will be filled, current and
saved.
I have my default set to 5 days because I sometimes do not use AB RT every
day.
It is really a very simple process once you do it a couple times.

Hi Wes,
Yes have had this problem since day one, have submitted bug report with
photos, and have given up. Strange to have symbols in the RTQ window
showing
quotes but at the end of the day no graphs are available. As you state
one
must have a symbol graphed and maybe even displayed for the quotes to be
saved. Every 30 days back fill the symbols manually.

only in the RTQ list.
I'm using the IB Feed and have all my symbols in the RTQ window. There's
only about 40 or so of them.
My understanding was that AB would collect data for any symbol in the
RTQ
list.
It collects data for symbols open in a chart window, But it does not do
this for symbols that are only in the RTQ window.
For these, I have to force a backfill at the end of the day.
The Database is set for Local Data Storage, 500000 quotes, 1 minute
data.
Does anyone else have this problem? I probably have some setting wrong
and
would appreciate any advice .
Using 490.3, but had this in the prior versions too.
