Celebrated technician Richard Wyckoff wrote about financial markets in the early decades of the 20th century. His revolutionary approach to technical analysis has survived into the modern era, guiding traders and investors on the best ways to pick winning stocks, the most favorable times to buy them, and the most effective risk management techniques. As Wyckoff became wealthier, he also became altruistic about the public’s Wall Street experience. He turned his attention and passion to education, teaching, and publishing exposés.
