Hi all,
To contribute to this topic I have to say that "my AB" is working fine with IB: I have 55 IB symbols in my database (futures, cash, stocks and index), time frame set to 1 minute and backfill set to 30 days and, although I have from time to time the "throttling" message from IB, it works just fine.
I observed however that even if having 55 symbols is ok, you need to make sure to not have more than 6 to 10 symbols charted at the same time, precisely to prevent this "throttling message" to pop up and slowdown the entire process.
So due to this IB (and not AB) limitation I would suggest you create layout with no more than 10 symbols, ideally 5 or 6, and you will see it will work fine.
Hope this helps,
Carl

Actually, I assumed that the plugin would use my database setting to limit this value. Why should the plugin download 180 days of data when my database is only configured to store 5 days?
