Speaking of which, and a problem I run into frequently, and again this evening - sometimes the backtesting tool works well and other times it fails to give a result.
For instance, I was using it to backtest a mean revision program I'm writing yesterday. It was returning the results without problem. Today I sign on and want to run a set of results without a single change in the program so that I can view my previous results as a baseline for today's adjustments to the equation, and of course - today it fails to return any results, even though nothing at all has changed on my end. VERY FRUSTRATING.
