People are talking about "price action" as if there is an agreement on what that means. Is there? Is "price action" simply price data or price-based signals? If so, yes some can find a way to make money with that. Its also true you can't learn it in a book.
Here is the problem. Data is just data. it does not contain inherent signals. Does not matter what kind. Do some traders use price data to find systems and trades? sure. But it is not a fixed body of knowledge. This about it. That would assume that ones counter-parties where permanently stupid and never learned - they just give money away if you follow a canned pattern. That is not how it works. The market is a competitive process, not a mechanical process.
That brings me to one of the great myths (similar to what I have stated). That there are all these great strategies written about in books or guru courses, and it is just "super hard" to have the discipline or fortitude to trade them, or the "craft". IMO its NOT TRUE. Good ideas actually work. Aside from severe mental or emotional problems its not that hard to trade if one actually is using stuff that works - and of course the real problem is that most don't have anything that works worth a damn.
