Rate of Change (ROC)
Web3 / technical analysis
Rate of Change is a momentum oscillator that measures the percentage change in price between the current price and the price from a specified period in the past. ROC calculates how quickly price is changing by dividing the current price minus the past price by the past price and multiplying by 100. Positive ROC values indicate upward momentum while negative values indicate downward momentum, with larger absolute values suggesting stronger momentum in either direction. ROC oscillates around a zero line, making it useful for confirming trends and identifying momentum divergences that may precede reversals or consolidations in price action. Example: A Bitcoin trader using a 12-period ROC on daily charts might see ROC turn negative before price breaks below a support level, confirming that buying momentum has weakened and suggesting a downtrend may be forming. Why it matters for crypto technical analysis: ROC provides a straightforward momentum measurement that helps crypto traders gauge the strength and sustainability of price moves, with divergences between price and ROC often signaling potential reversals before they occur in volatile markets.
