I remember reading "Bankruptcy 1995" and laughing at the conclusions he was reaching. He lost a lot of credibility with that book. Yes, we can get to a point where we won't be able to pay our bills but back in the early '90's when I read it, I knew it wasn't going to happen in 1995.
No, because there are so many people trading in a market that volume alone erases any advantage that someone might have discovered with a system. All systems are basically particular views of a market.
