1. I am using proprietary blackbox I-Ching (Chinese book of Change) methodology to predict the future.
It's based on a proprietary autoregressive polymorphic hexogramm recombination technique, which utilizes the heteroskedasticity scaling effect in financial time series.
This is a highly sophisticated gamma-technique, which I am prepared to disclose to a select group of dedicated followers, for a special fee of only $17.
2. I use the Hoadley Probability calculator to try predict the future, with varying degrees of success:

(you can get volatility estimates, an input for the calculator, from ivolatility.com, a free resource). The problem is this assumes you have an equal 50/50 chance of the price going up or down, so you can't predict direction, but you can predict price range, with some precision (assuming your volatility estimate is right).
It is a good tool.
3. I'm also trying to get Forecast Pro, a forecast software tool, to predict stock prices, but it's not very good at that. Although I have to say this: the confidence intervals, i.e. price range estimate, do catch the price range fairly well.
