Adapting RSI Lookback Periods to Market Volatility

Summary

This note describes an RSI variant that adjusts its calculation period using a simple volatility measure. The aim is to make the momentum indicator respond to changing market volatility, addressing the fixed lookback period used by a conventional RSI. The document refers readers to a separate explanation of the volatility measure but does not give its formula here.

It says the adaptive calculation uses a custom RSI function because the required period can vary and cannot be known in advance; creating built-in RSI instances for every possible period would be inefficient. The note provides no performance tests, parameter guidance, or trading examples. It advises applying the usual RSI trading rules, but does not explain or validate those rules for the adaptive version, so its practical benefits remain unsubstantiated in this document.

Key ideas

• The indicator varies its RSI calculation period according to a simple volatility measure.
• A custom RSI calculation is used because the required lookback period changes dynamically.
• The note recommends interpreting the adaptive indicator with conventional RSI trading rules.
• No empirical results or specific parameter guidance are provided.
