Equivolume Definition & Chart Examples

Equivolume Charts Definition

Equivolume charts display the relationship between price and volume in a bar. The top of the bar is the high of the session and the bottom of the bar is the low of the session. Equivolume charts differ from other price bars in that the width of the bar is determined by the volume on the session. The larger the volume, the wider the bar. Equivolume chart patterns are discussed in great detail in Richard W. Arms, Jr. book "Profits in Volume".
