Pattern, Price & Time proved to be a bit of a disappointment. I was looking for a book to explain the application of Gann Theory to securities trading, but the book neglected a rather significant part of Gann's work. William Gann's use of significant anniversary dates and special numbers (ie.with some linked to biblical references, others to astronomy) is what distinguishes his work from the miriad of other technical trading authors. Pattern, Price and Time did provide some useful technical trading concepts. In neglecting the more esoteric aspects of Gann's work, however, it was little more than a dry recitation of technical trading rules.
