haha fair enough - thinking about it there's all kinds of nefarious ways you could use the data. Looking at your product a bit more, this might be complicating things a little and it's going to hammer your database but I'd love the ability to fit variables to a strategy - eg I want a strategy like "IF X day moving sample average for GOOG is better than Y day moving sample average for GOOG buy ELSE sell" But I don't really know the best X and Y, so I'd like to leave those as variables and have the software find the optimum values based on historical data.
