# What does Smoothed Rate of Change mean?

## 10 Answers

Smoothed Rate of Change was first introduced by Fred G Schutzman in Futures magazine, April 1991. The oscillator performs a similar function to the Momentum and Rate Of Change indicators but avoids some of the weaknesses:Ã¢â‚¬Â¢Because of the smoothing the indicator is less erratic and gives fewer false signals;Ã¢â‚¬Â¢The exponential moving average ensures that the indicator only "barks" once. Smoothed Rate of Change (SROC) first calculates a 13-day exponential moving average of closing price. Then calculate a 21-day Rate of Change of the exponential moving average.

This indicator, developed by Fred Schutzman, is described in TRADING FOR A LIVING. It is created by calculating the rate of change for an exponential moving average of closing prices. When it changes direction, it helps identify and confirm trend changes.Source :www.elder.com

Rate of change is often illustrated by the Greek letter delta. Many traders pay close attention to the speed at which one variable changes relative to another. For example, option traders study the relationship between the rate of change in the price of an option relative to a small change in the price of the underlying asset, known as an options delta.

The ciSROC (Smoothed Rate of Change) indicator is a modification of the traditional ROC, as described in Alexander Elder's book Trading for a Living. It plots two lines: ROC, which is the difference between the current price and the price x-time periods ago, and SROC which is the difference between an MA of price and the MA of price x-time periods ago

Developed by Fred G. Schutzman, the smoothed rate of change is different from the typical rate of change by using an EMA as opposed to closing values for computing the rate of change. By using the EMA, as opposed to price, the resulting ROC signal does not succumb to rapid changes triggered by the price.
