Quote from Thunderdog:
Having studied statistics in both my undergraduate and graduate studies several years ago, I have a nodding acquaintance with that discipline. I think you will find statistics to be a better post-dictive tool than a predictive one as it relates to the markets. The problem with the markets is that there is no known and constant probability distribution for what has not yet occurred as compared to what has already happened. Therefore, you are dealing more with uncertainty than you are with probability. As a result, I think you will find pinpoint accuracy even more elusive than when dealing with known probabilities. But why quibble? I look forward to your report of actual trading performance in due course. And I really do hope you knock everyone's socks off, but I suggest that you play a defensive game, at least at the outset. Going for 1% or more per day is far from defensive. Either way, good luck.
