SPM works, it all depends on your understanding of a working pattern. Which pattern is it? Usually the best one is the one that creates 2 to 3 declining peaks or 2-3 rising lows prior to hitting the 0 line. I would only trade those set-ups using SPM, ie 2-3 failure crosses & only then I would enter. It's like in Blackjack in a way, who has a more favourable odds of getting a better hand after you have 4-5 consecutive losses, you or a dealer? You, of course. Are you always gonna have a winning hand after 4-5 consecutive losses - NO. Is SPM The Holy Grail - NO. What is SPM? It is a fantastic easy to understand pattern that works most times when right conditions are present. Why do you need 2-3 failure crosses? Because that way longer term charts are getting prepped for a larger move & that is all that is important.
