Volume Price Analysis
Volume Price Analysis (VPA) is a term coined by Anna Coulling and described in her trading book “A Complete Guide to Volume Price Analysis”. It is similar in concept to Volume Spread Analysis (VSA) which is a term coined by Tom Williams of TradeGuider. Both VPA and VSA are based on the works of Richard Wyckoff, Charles Dow and Jesse Livermore, traders famous in the 1920s.
The idea behind VPA is to uncover supply and demand in any stock using volume in combination with price and spread (the difference between Open and Close).
The book explains in detail the concepts and ideas behind VPA and is recommended reading for anyone interested in the topic.
