William D. Gann (1878) was born in Texas, USA, and was the most famous investor in the 20th century. The outstanding achievements in the stock market are unparalleled so far. Gann was born in Ravdin, Texas, USA on June 6, 1978. His parents are Irish immigrants. In his investment career, the success rate is as high as 80%~90%. He made a huge fortune with a small amount of money. During his 53-year investment career, he made a net profit of $350 million from the market.

1902, 24-year-old Gann entered the market for the first time to buy and sell cotton futures. 1906, Gann went to Oklahoma as a broker, not only for his own speculation, but also to manage customers. 1908, when Gann was 30 years old, he moved to new york and set up his own brokerage company. On August 8 of the same year, he developed his most important market trend forecasting method, which was named "Controlling Time Factor". After many accurate predictions, Gann became famous. According to Kealey, Gann's friend, "In the summer of 1909, Gann predicted that the wheat option would meet 1.20 in September. However, by September 30th, Chicago time 12: 00, the option was still hovering below $65,438+$0.08, and Gann's prediction was dashed. Gann said: If I don't see 1.20 dollars at the close today, it means that my whole analysis method is wrong. Regardless of the current price, wheat must see $65,438+$0.20. As a result, an hour before the market closed, wheat rushed to $65,438 +0.20, which shocked the whole market. The contract was fair and closed at $65,438+$0.20.

At the peak of Gann's career, he hired 25 people to make various analysis charts for him, conduct various market trends research, and set up two trend research companies: Gann Science Service Company and Gann Research Company, and published various investment newsletters. In the annual trend forecast he publishes every year, he clearly draws the forecast trend chart of when to look at what price, which is very accurate.
