What I am saying is there is no correlation between what happens over the next X hours (days, weeks, months) with what happened over the past Y hours (days, weeks, months).
What about market patterns that repeat? I'm thinking about seasonality plays, presidential cycles, or (even simpler) end-of-month index plays. These are independent events. They repeat. Would it not be more profitable to take advantage of these patterns then to pick a "buy" date at random?
