I have used AB with my QuoteTracker feed for over a year now. Of course I have some gaps in my data because QT and my source, Fidelity account, will not permit backfills. Suddenly, yesterday, AB is totally bogged down if I select 5 minute data. When I start it up, it automatically comes up in hourly mode and is ok. Switching pole positions for example is almost instantaneous. If I switch to 15 min display, I get a noticeable delay, maybe 3 to 5 seconds for the pole to appear. (I also have the Task Manager open and can watch broker.exe jump to the top of CPU usage and then drop down. If I click on 5 min data, CPU goes to 100%, Broker.exe is pegged at near 92 to 95% and it will take literally 1 to 2 minutes to get the cursor back. Again, the day before yesterday, everything worked fine. What changed? Nothing that I know of. I was experimenting with a rather long formula file (developed in EOD environment), and earlier versions worked ok, but maybe this had something to do with the slowdown. I deleted the formula from the RT database, and rebooted the computer. What else can I try and what other data can I gather to diagnose this problem? Thanks. Running AB 5.19, with XP and plenty of RAM and HD
