[amibroker] When are indicators for symbols calculated in RT?

Perhaps this was mentioned before - but I can't recall/retrieve the 
answer.  During RT-intraday mode, I have a 1min,2min,5min,15min and 
daily chart on screen, all symbol linked (with only 1 symbol 
displayed and updating).  By display chart timing the total time (sum 
for all charts and panes visible)= 0.4 sec (by eyeball, when I change 
a symbol it takes about 3-4 sec for the new symbol to be displayed).  
If I run an AAexplore over the entire db (100 symbols) in 5min 
periodicity using an afl that is equivalent to the 5min chart + a 
portion of the 15min chart, I get results in 2 seconds.  

It seems AB had the results before I started the AA (otherwise why 
wouldn't it take at least 0.4sec/symbol * 100 symbols). What I'd like 
to know is if/what afl's does AB run in the background.  Does it just 
continue updating the last AA afl that was run - anticipating that it 
will be run again (even though the run every box is unchecked).  Is 
there a way to control the frequency &/or symbols this AA is run (if 
it is)?  

Are the CHART afl's run on all sym in the db (or the last X symbols 
displayed on these charts or the last X symbols reported in an AA run 
or the last X symbols viewed in RTQ window) being run while I just 
have 1 symbol displayed?  Is there a way to control this? - ie, run 
over fewer symbols?

Thanks for any consideration of this issue,
Dan
