I'll answer my own question. I was missing two things. First, I was using "MarketID" in my filter to set different minimum prices for NASDAQ and NYSE stocks. This data is normally available with QP3 but the data from IB has very little system information so the filter failed.
The second problem was simpler. QP3 volume data is in ones and IB data is in hundreds so the volume filter failed as well.
It turns out there was a third problem of a practical nature. Sometimes I have to enter up to 50 new stocks into IB each night. I need about 20 days of RT data to make the charts for the next day. IB backfill is such a pain that it can take me up to 1 1/2 hours of manual tinkering to get the data past IB's historical and pacing restrictions. Man, I hate IB backfills.......
Anyway, problems solved and now getting explorations and AA system tests to run on IB data as well as QP3
data.
Cheers

I have a system and exploration developed in EOD AmiBroker using QP3 data. It runs just fine.
If I switch from QP3 EOD to IB data and run the code there is just a quick flash of the screen and no results are generated.
OK I thought, it probably is too much to expect the code to run on RT data so I switched AB to display daily bars but still fed with RT 1m data from IB.
Still nothing, just the quick screen flash and no results. What am I overlooking that causes no results from the system ot exploration?
In AB fed with IB I just have a few stocks that I entered manually and there is not much system info associated with them, if that makes a difference.
