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. Cheers Sid
