Well the only thing I can think of then is that the TC2005 database plug-in
retrieves all available bars for each symbol. The code below only needs 1
bar. And I can't think of any other parameters or settings to change.
Anyone else using TC2005 and experiencing their explorations running slow?

I have a CSI database, but I ran your test file anyway.
If I pick N last quotes = 1 it takes 54 seconds to run on 14,400 stocks.
If I pick all quotes (in this case, 500 bars and 14,400 stocks) it takes
~15 minutes to run.
Hope this helps.

Hi Duke,
Here is a sample AFL scan that takes 7 minutes.
PRF = ParamToggle("Check for Price in range?", "No|Yes");
HCV = Param("High close value ", 50, 5, 300, 0.5);
LCV = Param("Low close value " , 5, 1, 10, 0.25);
PR = (Close >= LCV AND Close <= HCV);
My_Conditions = IIf(PRF,PR,1);
Filter = My_Conditions;
Buy = Filter;
AddColumn(C, "Close", 2.2, colorDarkGreen, colorLightGrey);
This is simplified down and still takes a while to run. It would be
nice to
know where the problem is (if there is one).

Dave,
That scan time does seems awfully long. I ran a simple scan of
C>=(Ref(C,-1)*1.20) and it took only about 2 minutes on an older Dell
Computer.
I am not sure how to keep all the data from loading as I have the same
issue with QP but there might be some other issues that are also
affecting your scan times.
You might check out Dan Clark's batch scripts or Fred's Batman to help
automate the task as well which might also save you some run time.
Regards,
Duke Jones, CMT
