This archive contains a PowerPoint presentation showing 10 lessons on trading Murrey Math, and it includes an overview of "how to trade Murrey Math Lines (MML)" by a fellow trader.
The Murrey Math trading system is primarily based upon the observations made by W.D. Gann in the first half of the 20th century.
While Gann was purported to be a brilliant trader in any market his techniques have been regarded as complex and difficult to implement.
The great contribution of Murrey Math (T. H. Murrey) was the creation of a system of geometry that can be used to describe market price movements in time. This geometry facilitates the use of Gann's trading techniques.
