How It Works

ROC = ((Current Price - Price n periods ago) / Price n periods ago) × 100. It oscillates around zero, with positive values indicating upward momentum.

Extreme ROC readings can indicate overbought/oversold conditions. Zero-line crossovers suggest trend changes. Divergences are used to spot potential reversals.
