Momentum
Rate of Change
ROCCalculates the percentage change in closing price over N periods. Positive values mean price is rising; negative means falling. It oscillates around zero and helps traders gauge momentum strength.
Tips
ROC zero-line crossovers lag less than MACD crossovers but are noisier; combine with a trend filter to reduce false signals
Extreme ROC spikes often mark climactic moves; rapid mean-reversion trades can work after historically large readings
