One easy way to see if the CPU hog is AB or not, minimize AB. If CPU usage drops significantly, it is AB.

Thanks Tomasz. I have no no loops. No complex indicators. Just a lot of timeframe expands. I will try the AFL timing and see. If I am unable to find out I will send it to support. I have no doubt that AFL is the fastest out there. I have been using amibroker since 2004 and I love each and each every day of my experience with it. Its just that I am perplexed why the CPU would get bogged down like this. Thanks again. Will try the AFL timing you and Herman put together.

That's simple: one of your formulas is very badly coded - and it eats the CPU. Under normal circumstances the CPU floats in 8..20% use. You need to use Tools->Preferences->Miscellaneous and check "Display chart timing" then watch the timings each chart is showing. All built-in formulas execute well below 0.1 second and this should be your target. If any formula needs more than 0.5 sec to execute it is badly written and it should not be used. You must either rewrite it or send it to us and we will tell you what is wrong. But again: any formula that executes in more than 0.5 sec is NOT to be used in real-time and requires either rewrite or removal.

Folks: Attached is the task manager output when Amibroker 4.90.5 is runnning. It always spikes back and forth and stays very high near 90-100% . process shows broker.exe spiking. I have only 6 charts attached. I have noticed this in the past when I had indicators attached to more than 8 charts. Now I have only 6 six. Other than 1 , all other indicators are all fairly simple...no looping etc..But uses timeframe expands from daily etc. I have intel p4 2GHz cpu with 768MB ram. anyone else seeing this?. Thanks,Padhu
