The Master's Words
The Writings of W.D. Gann

William Delbert Gann remains one of the most enigmatic figures in market history. A trader, mathematician, and astrologer, he claimed to have discovered the natural laws governing market movement. His writings — part technical analysis, part natural philosophy, part something else entirely — have fascinated and confounded readers for over a century.

"Vibration is fundamental; nothing is exempt from this law; it is universal, therefore applicable to every class of phenomena on the globe."

Wall Street Stock Selector, 1930
