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.

Hi
I have just done some checking on my afls. 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?
