Using Ehlers’ Dual Differentiator to Read Market Regimes

Summary

The document introduces John Ehlers’ Dual Differentiator as an indicator intended to measure market cycles or periods. It characterizes the indicator as a regime-reading tool rather than a directional signal: rising values are described as a trending mode, while falling values are described as a changing mode. The note also suggests using it in a momentum-like role or to adapt other indicators to changing market conditions.

The explanation is brief and does not give a formula, parameter settings, chart examples, asset class, or rules for entering and exiting trades. It presents no tests or evidence that the regime interpretation improves results. Traders would need to consult a fuller implementation and evaluate the indicator against their own data before relying on it; the description alone does not specify how to distinguish meaningful changes from noise or how to combine it with other signals.

Key ideas

• The Dual Differentiator is presented as an indicator for assessing market cycles or periods.
• The note describes rising readings as a trending regime and falling readings as a changing regime.
• It is explicitly described as non-directional rather than a buy or sell signal.
• The indicator may be used in a momentum-like role or to adapt other indicators.
• The document supplies no formula, settings, or empirical performance evidence.
