I am reconstituting the best I can the end-of-year Nasdaq100 membership from 2007 forward. Initially I am going to backtest using AI on each of those annual universes from then forward. Then I am going to try to create the changing Nasdaq100 universe including during each calendar year and backtest against those. I am trying to avoid paying Norgate but may end of doing that. If someone has a specific test that they want that only uses price and volume let me know. Once I do the above I may try this "WarrenAI" to add what data it has. So at least we can duplicate some of Robbie's backtester assuming he is not going to support it going forward. I am doing so well using the Nasdaq100 as the sub-universe this seems a good place to start and will involve less downloading of historical data than larger universes.
