The Tunnel Thru the Air, as many serious students of WD Gann would know, is the most important book that the great market forecaster had ever written. Published in 1927, it foretold the crash in 1929, and every turning point in the subsequent bear market until 1932. It did not only specified that the bottom would be in July 1932, but also predicted the number of points of each rally and correction!
The casual reader would see none of the above when they read it, because the information is well hidden in an otherwise ordinary love story. To decode this book, you must understand the coded language with which Gann hid his method. See the videos below:
