A trading psychology classic that shows how discipline, probability thinking, and emotional control separate consistently profitable traders from the rest. A must-read for anyone serious about the markets. Douglas breaks down the mental traps that cause even skilled traders to lose money, including fear, overconfidence, and the need to be right, and replaces them with a probabilistic mindset built on discipline and consistency. It remains one of the most recommended books for anyone moving from gut-feeling trading to a structured, rules-based approach.
