TJ:
Thanks for the trick. I am trying it out now.
I need generally quotes for 100-110 tickers, but I can afford some delay upto a couple minutes.

Hello,
Real-time data are generally delivered on demand.
Getting data needs subscription to given symbol, only then
you can get current price.
If you call GetRTDataForeign for more than 100 symbols in
IB (their limit) it will
subscribe new / unsubscribe old but this is not
"immediate" as it takes time (upto few seconds)
for IB/TWS to process subscription/unsubscription request
for given symbol.
If you don't want backfills to be triggered automatically,
simply
uncheck "Automatic backfill on first data access" check
box in the File->Database Settings->Configure
as described here:

Subject: Re[2]: [amibroker] Is "price on
demand only" possible in Amibroker?
No Mark, I have no solution. afaik, Backfill cannot be
disabled.

This is an old post but I do have exactly the same
question.
I don't need streaming and backfills, just the open
prices by getRTDataForeign() from IB data plugin.
Have you figured it out? or heard anything from TJ
himself?
Thanks,

For better real-time execution speed and to
eliminate IB backfill problems (IB lock-out and DB-corruption), I
want to work without any historical data, arrays, or
backfill.
I just want to be able to get a, using
getRTDataForeign(), a specific price when I need it. For
efficiency prices may be "sampled" at different rates depending on
my system needs.
1) Is it possible to limit data collection
through the IB data plug-in to getRTData() functions
ONLY?
2) Would I even need a database for such a
setup?
Is this possible?
thanks,
herman
