William Gann's impressive achievements in the stock and futures markets are unparalleled to this day. The theory he created that perfectly combines time and price is still talked about by people in the investment community. Highly respected.

Gann was born on June 6, 1878 in Lufkin Texas, USA. His parents were Irish immigrants. In his investment career, the success rate was as high as 80% to 90%. He made huge wealth with small money. In his fifty-three years of investment career, he obtained 350 million U.S. dollars from the market. net profit.

In 1902, at the age of 24, Gann entered the market for the first time to trade cotton futures.

In 1906, Gann went to Oklahoma to work as a broker, not only doing business for himself but also managing clients.

In 1908, when Gann was 30 years old, he moved to New York and established his own brokerage business. On August 8 of the same year, he developed his most important market trend prediction method, called "Controlling the Time Factor". After many accurate predictions, Gann became famous.

The most eye-catching one was an on-site visit by Richard Wyckoff, editor of the American "The Ticketr and Investment Digest" magazine in October 1909. Under the supervision of magazine staff, Gann made 286 transactions in the 25 market trading days in October, resulting in 264 profits and 22 losses, with a profit rate of 92.3%.

According to the recollection of one of Gann’s friends, Keeley: “In the summer of 1909, Gann predicted that the September wheat option would hit $1.20. However, as of 12:00 Chicago time on September 30, the option was still Wandering below $1.08, Gann's prediction seems to have failed. Gann said: "If the market closes today without seeing $1.20, it will mean that my entire analysis method is wrong. No matter what the price is now, wheat must see $1.20." , one hour before the market closed, wheat rushed to $1.20, shocking the entire market. The contract closed exactly at $1.20. "

Gann believes that there are also natural rules in the universe in the stock and futures markets. The price trend of the market is not chaotic, but can be predicted through mathematical methods. Gann's mathematical equation is not complicated. The essence is that price movement must obey the support line and resistance line, that is, the Gann line.
