Mass Pressure Chart 2013

Several years ago the Mass Pressure Chart was hyped and sold as W.D. Gann's ultimate secret. Daniel T. Ferrera, a pundit on the matter, admits: "I have talked to many Gann experts about the Mass Pressure Chart and most have no clue as to what it may be. I have never seen an actual original Mass Pressure Chart from W.D. Gann and I do not know of anyone else who has come across one."

However, it seems the Mass Pressure Chart is but a selective or incomplete Decennial Pattern: Each value of this equally weighted composite is derived from 6 past price values of the DJIA exactly 80, 60, 40, 30, 20, and 10 years back. The Mass Pressure Chart and the Decennial Pattern oftentimes look very much the same, and have identical turning-points.
