Never trust stories about how to make money in the stock markets, unless said stories are told entirely in the past tense. If someone really does have a successful trading strategy, the only way it makes economic sense to publish it is if they believe they can make more money by publishing it now (i.e. selling books, pageviews, whatever) than by using it to trade. Either that, or the algorithm is being described in sufficiently general terms that you're not actually given enough information to use it effectively.
