• Rate of change (ROC) refers to how quickly something changes over time.

  • Thus, it is the acceleration or deceleration of changes (ie, speed), and not the magnitude of the individual changes themselves.
  • In finance, rate of change is used to understand price retracement and determine trend momentum.
  • Moving averages are used by traders to understand the rate of change in asset prices by smoothing them out.
  • The price change rate indicator is a technical tool that measures the percentage change in price between the current price and the price a certain number of periods ago.
