Just to clarify some things. J-chart is not based on the same principles as market profile. Market profile uses volume and fixed time intervals to locate value areas and points of control. It uses statistical analysis to indicate the distribution of trading activity.

J-chart is time independent and does not use volume at all, only price action. It defines the states of trading activity as either building equilibrium or breaking equilbrium (chaos). The basis is fractal theory and the formation of perfect equilibriums. Anyway suffice it to say that j-chart has nothing to do with market profile and vice versa.
