For years, the interest of numerous market scholars has focused on W.D. Gann, the architect of very successful market predictions. Eager for knowledge, a plethora of speculators have tried to find out how Gann was able to obtain such a level of precision, making such wise market predictions. For example, in number two of the fifth volume of the magazine Ticker and Investment Digest (December 1909), it is mentioned that Gann carried out 286 trades in the presence of William E. Gilley, of which 264 were successful. Therefore, his win ratio reached a spectacular 92%. In that 25-day period covered by the article, Gann was able to double his starting capital ten times.
Among Gann’s many speculative techniques, perhaps the most famous is the one known as the Square of Nine, one of his most mysterious calculations and trading systems.
