The Man Behind the Method
William Delbert Gann was born on June 6, 1878, in Lufkin, Texas. Raised with a deep religious foundation and a love of mathematics, he entered the brokerage business in 1902. By 1908 he had developed his core analytical framework. In October 1909, financial journalist Richard Wyckoff witnessed Gann execute 286 trades in 25 market days — 264 of which were profitable. The documented strike rate of 92.3% remains one of the most extraordinary records in trading history.
The Law of Vibration
Gann’s foundational insight was that markets operate according to mathematical laws. He called the primary law ‘The Law of Vibration,’ arguing that each stock and commodity vibrates at its own unique rate determined by its supply and demand history and its position within larger market cycles. By determining this rate, future price movements could be forecast with mathematical precision.
His Most Important Discoveries
Gann’s work produced several major analytical frameworks: the Gann Angle system relating price movement to time in geometric ratios; the Square of Nine as a mathematical calculator for price targets and timing; the concept of time cycles where markets repeat at specific measurable intervals; and the use of planetary positions as precision timing tools.
Why Gann Remains Relevant
Gann was not describing market behaviour — he was describing human behaviour. The fear, greed, hope, and despair that drive markets have not changed, and neither have the mathematical relationships that emerge from collective human action. His methods identify these relationships and project them forward in time.
Gann’s methods are not a system to be applied mechanically. They are a framework for understanding the deep natural laws that govern market movement — a lens through which price and time become fully intelligible.
