  Subject: [amibroker] RT AB Sluggish at 
  Small Time Settings
  
  Can someone suggest what 
  I may check or diagnosis to get a handle on and fix for this 
  problem.
   
  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.
