Using RSI to Adapt an Exponential Moving Average to Market Conditions

Summary

This note presents an adaptive exponential moving average whose calculation changes in response to the Relative Strength Index. It frames the RSI as a bounded momentum measure that can also serve as an input for adapting an indicator to changing market volatility. Because an EMA can use a fractional period, its smoothing can be adjusted more continuously than an average restricted to whole-number periods.

The note identifies the RSI period and input price as parameters and suggests using the resulting line like a conventional moving average. A change in its color may be treated as a signal, but the author advises caution. No precise mapping from RSI values to the EMA period, formula, backtest, or performance evidence is provided, so implementation and effectiveness cannot be assessed from this description alone. The volatility interpretation and any trading signal would need independent definition and testing.

Key ideas

• The indicator adjusts an EMA using RSI as an input.
• The note treats RSI as both a momentum measure and a possible proxy for changing volatility.
• Fractional EMA periods allow the smoothing amount to vary more continuously.
• The suggested parameters are the RSI period and the price used in the calculation.
• Color changes are mentioned as possible signals, with a caution to use them carefully.
