The Rate of Change (ROC) oscillator is an unlimited momentum indicator used in technical analysis, set against the midpoint of the zero level.
An ROC rise above zero usually confirms an uptrend, while a ROC fall below zero indicates a downtrend.
When the price consolidates, the ROC will fluctuate around zero. In this case, it is important that traders keep an eye on the overall price trend as the ROC does little more than confirm consolidation.
