I'm not talking about Wealth-Lab type software, where you have to specify a portfolio of stocks to backtest a strategy on. I'm referring to software that you define a strategy for picking stocks, and it will look backwards (based on a user-defined timeframe) and test against the entire universe of tickers to determine which stocks would have been chosen by your strategy through time and how those stocks would have performed. The only apps that I found that can do that are Zacks Research Wizard and VectorVest Autotester & Simulator. I've tried both, and they both have pluses and minuses. But, I'm wondering if anyone's tried any other backtesters out there and could make any recommendations. Thanks for your help!
