Mark Douglas

Mark Douglas (1948-2015) was a leading expert in trading psychology and founder of Trading Behavior Dynamics, a firm that coached traders to overcome emotional and mental roadblocks. After starting in commercial insurance, he became a full-time trader, which led to a decades-long career helping traders master the mental side of the markets. His work was instrumental in shifting the industry’s focus from analysis to mindset, and his books-The Disciplined Trader and Trading in the Zone-remain classics in the field.
