To our knowledge the greater part of William Dunnigan's life was dedicated to a close association with stock and commodity markets and what makes them tick technically. Technical Analysis was extremely important in his life as it was in this field of endeavor where he eventually decided lay the keys to the exploration of the interacting forces of time and price movements. His prowess as a market researcher and the many papers he produced on his findings, we know, earned him the respect of his peers, a thing he appreciated. His finest writings can be found in the last two books he wrote before passing away in 1957 - New Blueprints for Gains in Stocks and Grains, 1956 and One-Way Formula for… Trading in Stocks and Commodities, 1957.
