◆ The PatternROC = ((Close − Close_N) / Close_N) × 100.
Rate of Change — a pure momentum oscillator measuring percentage price change.
ROC = ((Close − Close_N) / Close_N) × 100
Oscillates around zero. Positive = upward momentum; negative = downward.
Uses:
• ROC crossing above zero → bullish shift
• Divergences between ROC and price signal weakening trends
• Common period: 12 or 14
• ROC crossing above zero → bullish shift
• Divergences between ROC and price signal weakening trends
• Common period: 12 or 14
Pattern bridge: Rate of change is the discrete gradient of price — the slope at each point. In statistics, it’s the first difference used to make time series stationary.
