ROC: Rate of Change
How much the price has changed in per cent compared with N candles ago.
La idea en pocas palabras
ROC is momentum in its simplest form: the percentage move over a fixed look-back. Above zero the price is higher than it was, below zero lower.
Cómo se calcula
Divide the change since N candles ago by the price N candles ago and multiply by 100.
ROC = (close − close[N]) ÷ close[N] × 100Cómo usarlo
- Crossing zero: momentum turns positive or negative.
- Divergence: price makes a new high while ROC does not.
Sacar conclusiones
- Extreme readings compared with the ticker's own history often come before pauses.
Ejemplo
AAPL daily, ROC(12) = +8%: the price is 8% above where it was 12 sessions ago.
Los precios de los ejemplos son ilustrativos.
Ten cuidado con
- One unusual candle N candles ago makes ROC jump when it drops out of the window.
