tech, for the record, Tim Wood is NOT a pure cycles guy as far as I am concerend. He says that he mixes Dow Theory as well as Elliot Waves in his cyclical analysis (hence 3 dimensions of cycles. and hence the "abc" structure of market moves i.e. "waves").
Not trying to knock him off, but there are far more "real" cyclical analysts, say like Stan Harley or Peter Eliades.
