When the volume rises, the value of the VROC indicator is plotted above the zero line and vice versa. As same as, when the Price of a Security falls, the indicator moves down. In a minor change in Volume, the VROC slope tends to reach the central line. But with a major change in Volume, the indicator follows a breakout.
