If you can't state for definite what price will do in the next 5 minutes, then it proves that price is more random than not. I didn't say that we can't extract sense from its randomness, I trade patterns myself. But, I couldn't tell you what the performance will be in the future, only the past. That's why I agree with B1 on the notion that once you are right and move with a market it's imperative to try and stay with that move.
What price will do in the next five minutes may be unknowable, but that doesn't make it random. And that you can't say what price will do in the future does not mean that no one can.
If you're not interested in Auction Market Theory, that's fine. It's your money. But it's hardly secret knowledge. Hasn't been for at least five thousand years.
As for B1S2 being right, he wasn't very right about that short. If he understood AMT, he may have called it much sooner.
