Can I suggest changing the subject line when the subject changes? It is really hard to keep track of what the messages are about when they ALL have same subject while spanning the globe with contents I have noticed that the excution times reported by this tool are not always consisitent. When repeating the test multiple times, once in a while the result changes dramatically. But it is still helpful.

I have been custom cuting databases for a few years now to speed up run time. So I know from experience how much data these afls need before the start date. In looking at Code Check & profile, One of the AFLs state I need 4342 past bars before the start date, which is approx 20 years of daily data. I only have approx 18 years. So using QuickAFL wouldnt make any difference to the execution time. But from experimenting with various starting date in my custom database, I know that this afl only needs 400 bars (1 & 1/2 years) of data before the start date. Obviously, 400 bars back would make a marked difference in speed (thats why I started this years ago). I do not know why there is a difference between what AB calculates and what it actually uses. I also notice that setting the bars required manually to something less than what Code and Profile says makes no difference to either the results (which I would expect to ) or runtime. Is that correct that setbarsrequired cannot be set to less than What AB calculates?
