Thanks Bruce, I'll give it a shot - I've had issues only with systems that use the rotational trader. What I haven't had a chance to test yet is whether it is caused by my date restrictions or if it is caused by the rotational trading. I have two systems - one trades once per month, the other once per week. These are the ones having the errors - all of my normal systems (using traditional buy and sell signals) work perfectly.

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 -

This doesn't make any sense to me as Batman obviously just opens AB and runs the backtest there. I've saved the settings file for the backtest to make sure the settings are the problem, but I still get different results.
