Survivorship bias, as your mentor might say... No we don't know each other, apols for using your name.
He focuses on price behavior. He's studied and characterized his instruments and his market. He's prepared. It's nothing secret; it's just that so few people take the trouble.
Apparantly, it's mainly: Cup and Handle patterns, Falling Wedges, Ascending Triangles, Bull and Bear Flags
Yeah, but when I made that kind of money, I thought I was King of the world and I could never lose my Million+ dollars in commission back, but I did (like a fool) and I suspect Dan lost his own back too!
I suspect he focuses on the behavior that creates the pattern rather than the pattern itself. If the "secret" were nothing more than trading patterns, then anyone who traded patterns would be making his living thru trading. But it's not so simple, largely because those who focus on patterns ignore the behaviors that are creating the patterns. They therefore don't know when to press and when to hold back.
Anyhow, I am looking for a May 18 swing High in the stock market, basis various Timing methods and Cycles.
If by "pattern" you mean all price movement, arguably. But when people refer to patterns, they generally mean geometric shapes: flags, pennants, triangles, wedges, cups, horns, and so on. Which carry about the same weight as the big and little dippers and Orion's belt.
