Dynamic Momentum Index: Volatility-Adaptive RSI Periods

Summary

The Dynamic Momentum Index adapts the length of its calculation to changes in an asset’s volatility. Unlike the RSI’s fixed lookback, it shortens its period when volatility rises, making readings respond more quickly to price changes. The document describes interpreting it like the RSI, with low readings treated as oversold and high readings as overbought.

It also describes a modified version that uses the smoother RSX in place of RSI. The source claims this improves readability without adding lag, while noting that the original indicator can produce more false signals. No test results or supporting evidence are provided for the claimed improvement. The thresholds are presented as interpretation guidance, not as a complete trading system; the document does not specify entry, exit, or risk rules.

Key ideas

• The Dynamic Momentum Index varies its lookback period as volatility changes.
• Its period becomes shorter when volatility increases, which is intended to improve responsiveness.
• The document applies RSI-style overbought and oversold interpretations to the indicator.
• A modified version substitutes RSX for RSI to smooth the readings, but provides no evidence from testing.
