RE: [amibroker] When does AFL execute?

["Herman van den Bergen" <psytek@xxxxxxxx>]

1) afl executes each time a new quote arrives, for IB data a quote is a snapshot, for eSignal it tries to be for each and every trade. The are also some refreshes that occur when no data is coming in, these happen at abou 1-2 second interval.

2) Status() is sample at each afl execution

5) this depends on your SetBarsRequired(), AB uses a smart refresh (Quick-afl) that will only refresh the number of elements needed to create the visible display.

Subject: [amibroker] When does AFL execute?

Hi all,

I am having a hard time grasping some of AmiBrokers concepts and can't
find a the answer in the manual. Could someone be so kind as to explain:

1. How often during a Real Time intraday time bar do the AFLs execute?
2. ...During an RT tick bar (every tick)?
3. How many passes through the AFL get executed?
4. Is there one pass for each STATUS?
5. In real time do the arrarys get completely recalculated for
everybar on each pass?

Thanks for helping a new transplantee understand!

Jerry L.
