What is ROC?
Rate of Change (ROC) is a momentum oscillator that measures the percentage change in price over a specified period. It compares the current price to the price n periods ago and expresses the difference as a percentage, making it easy to gauge the speed of price movement.
Positive ROC values indicate upward momentum, while negative values indicate downward momentum. When ROC crosses the zero line, it signals a potential trend reversal. Traders use ROC to identify overbought and oversold conditions, confirm trends, and spot divergences between price and momentum.
