Smoothed Rate of Change Uses EMA Momentum to Assess Trend Acceleration

Summary

Smoothed Rate of Change (S-RoC) applies the Rate of Change concept to an exponential moving average rather than directly to closing prices. It compares the current EMA with its value a chosen number of periods earlier, expresses the difference as a percentage of that earlier EMA, and plots the result as an oscillator. The method is intended to indicate whether momentum is strengthening or weakening, which may help assess trend acceleration or deceleration.

The description specifies two lookback choices: one for calculating the EMA and another for comparing its past value with the current one. It provides example default periods and an indicator formula, but offers no chart examples, backtest, or performance evidence. Although the text describes the oscillator as ranging between positive and negative one hundred percent, it does not explain limits on possible values or establish that signals are predictive. S-RoC is presented as a momentum measure, not a complete trading strategy.

Key ideas

• S-RoC measures the percentage change in an EMA across a selected lookback interval.
• It uses separate periods for EMA smoothing and the rate-of-change comparison.
• The indicator is intended to show whether trend momentum is accelerating or decelerating.
• The document provides a calculation method but no performance tests or entry and exit rules.
