Droskill -

There are just too many "moving parts" in a batch backtest to hone in on 
probable issues, but I will try to offer a suggestion.  I'll also relate that I 
run 50+ batch explores and backtests nightly via Batman, and cross-check the 
results occasionally and have not seen problems.

BUT, long ago I wrote the AFL on the AmibrokerU site called BoilerPlate.afl and 
have referred people to it in order to debug similar issues.  Experience has 
show that it can prevent a number of problems, and that is why it is one of the 
first things that I put on the site.  BTW, it is included in all of those 
backtests that I mentioned that I run for a couple of reasons -

1. It makes me think about all of the settings and which ones to override.
2. Some settings can not be set via the Settings file and not having a default 
is akin to having an uninitialized variable (or one that may be initialized 
from the UI, but differently from COM).

My suggestion would be to first include that AFL and set the appropriate 
options to get a baseline, and then see if you still have the issue that you 
mentioned.
