[amibroker] Exploration hangs

["cyclicaltrader" <trading@xxxxxxxxxxxxxxxxxx>]

Hi,

I have a realtime database (IQFeed) with about 1200 symbols.  At the
end of the day I want to update the database with the latest quotes,
so I created a very simple exploration, with a filter= C > 100.

I have the "Wait for backfill" option checked. During the process, the
backfill operation stops. It doesn't freezes the program, it just
stops at a symbol and it doesn't pull any data.  I have no clue why
this is happening.

I can cancel the exploration and start again and it will stop again

I didn't manage to finish an exploration yet

Any ideas?

Thanks

Costas
