What is VROC?
VROC is a lower-chart line that shows the percentage change between current volume and volume from a selected past period. Larger values indicate a sharp increase in volume, while a rapid fall can accompany market stagnation.
How to use VROC
VROC shows the percentage change between current volume and volume from a selected earlier period. It is drawn as a line in the lower chart window, where larger values show a sharper increase in volume. On shorter timeframes, the line can rise rapidly before sudden price movement. A rapid decline can accompany market stagnation or a continuing range.
