A Rate-of-Change Standard Deviation Channel for Volatility

Summary

The document describes a volatility oscillator built from the rate of change of an applied price. It calculates rate of change over a chosen lookback, then estimates the standard deviation of that series over a separate period. Multiplying the deviation by a user-selected factor defines symmetric upper and lower corridor boundaries around zero. A move beyond either boundary is presented as a sign that volatility is increasing.

The indicator has four inputs: the rate-of-change period, deviation period, deviation multiplier, and applied price. It is a measure of unusual movement in returns, rather than a complete trading strategy: the document does not specify entries, exits, position sizing, or how to distinguish a durable volatility regime from a brief spike. It provides no backtest or evidence of predictive performance, so users would need to evaluate its behavior on their chosen instruments and data.

Key ideas

• The indicator measures price rate of change over a configurable lookback period.
• It forms symmetric bands using the standard deviation of the rate-of-change series.
• The deviation multiplier controls the width of the corridor.
• A breach of either corridor boundary signals an increase in volatility according to the description.
• The document provides no trading rules or performance tests for the indicator.
