Since the ROC indicator is a momentum indicator displayed as a histogram it is very easy to read and interpret. When it is above zero it shows upward price momentum, and when it is below zero it indicates downward price momentum. The further away from zero the indicator moves, the stronger the momentum of the price move. Traders can use this information either to confirm trend changes, or to inform them when a trend is gaining or losing momentum. The ROC is considered to be a confirming indicator and is typically used in conjunction with other indicators.
