Mark Douglas is a author who focuses on psychology of trading. His first book "The Disciplined Trader" published in 1990 is an industry classic, and along with "Trading in the Zone" published in 2000, these books are the FIRST books to introduce the investment industry to the concept of trading psychology ~ years before anyone heard of that concept, much less providing coaching in this now popular way of approaching trading. The field of Trading Psychology was initially thought of, and created by Mark Douglas, and introduced to the trading community by them in the mid-1980s. They are considered the "Gurus" of trading psychology.
One of their popular books "The Complete Trader" is available in the original format Mark and co-author Paula T. Webb envisioned - which is four separate and complete Sections - although it will be compiled it into one book with new materials in 2019. Another of their current books, the "Little Book of Trading Performance" is now available in its complete format. "Becoming the Disciplined Trader" which is the expanded version of "The Disciplined Trader," is one of their most popular recent books.
Mark began coaching traders in 1982; Paula took over his coaching business in 1999 when he went back to trading full time. They continued to develop seminar and training programs on trading psychology for the investment industry, as well as for individual traders for decades. Mark was a frequent speaker at seminars across the world, and along with Paula they traveled to 8 countries, as well as across the U.S., teaching traders how to become consistently successful. May of 2010 was the start of Mark and Paula hosting joint workshops (instead of individually) on the mental aspects of trading psychology, as well as the expanded field of prosperity psychology created by Paula. These workshops continue forward - check their website for upcoming dates.
