Decycler Oscillator: High-Pass Filtering of Price Data

Summary

The Decycler Oscillator transforms the Simple Decycler indicator by applying an Ehlers high-pass half-period filter to suppress strongly low-frequency components. It then expresses the filtered output relative to price and scales the result by a coefficient, which defaults to one. The documented inputs are the high-pass period, adjustment coefficient, and applied price.

The text explains the indicator’s construction and mentions illustrative figures showing it alone and alongside the Simple Decycler. It provides no trading rules, market examples, performance measurements, or guidance for interpreting oscillator values. As a result, it describes a signal-processing concept rather than evidence that the indicator predicts returns; users would need to evaluate its behavior and test any strategy built around it.

Key ideas

• The oscillator uses an Ehlers high-pass filter to reduce low-frequency components in the Simple Decycler.
• It converts filtered price data into an oscillator by relating the filter output to price.
• The adjustment coefficient defaults to one and can be changed when combining multiple oscillators.
• The description gives no evidence of predictive performance or recommended trading rules.
