I don't know if I should admit this, but I have read "New Market Timing" and "The New Science of Technical Analysis." DeMark is famous on Wall Street, and his reputation is that he is extremely successful. The original "quant" if you will. If you really want a challenge, read one or both of these books. If you want a painful challenge, write some of his systems into an Excel System or code it into Metastock or Tradestation (or now, into TOS). I did code all of his indicators into Metastock and back test them with average results. I know that I could have bought his system for Metastock, but what fun is that. Anyway, his systems, to put it mildly, are the Rube Goldberg puzzles of the system trading world. (Look up Rube on the net for some really COOL moving puzzles). Very complex, very multi-aspect indicators which try to cover every imaginable possibility. I guess if you have a team of programmers and sub-quants at your disposal, extremely complex systems are great. But for me, there are easier ways to make money (i.e. some of the systems on this site). OK, that being said, my advice is to try out some of his methods, but my experience was that they are so complex that they don't seem to work as well as all the hype surrounding DeMark. More simply, the profits don't justify the time and complexity. If you really want to use his systems, and they do have much public fanfare, make your way through the books. He does do a nice job of explaining his indicators step-by-step, which is nice if you want to program them. And unless you really want to own the books (if you are really going to use them over and over) get them from the library, as they are expensive. I did buy my first book, but NOT the second book, LOL.
