Query: The Best Christmas Present I got this year

The book is well written, easy to read. The author gives enough detail and diagrams to explain all the concepts. Along with John Murphy's "Technical Analysis of the Futures Market", these are the two best books I've read about technical analysis. My only concern is that the book is 8 1/2 years old, that some of the newer techniques and indicators aren't covered. John Murphy updated and upgraded his book, I hope this author also writes another edition.
