Simple Decycler Trend Detection with High-Pass Filtering
Summary
The Simple Decycler is described as a price indicator based on John F. Ehlers’s Decyclers article. It has configurable settings for the high-pass filter period and applied price. The stated purpose is to remove low-frequency directional components while isolating higher-frequency price movement, allowing it to respond quickly to changing market conditions.
The indicator plots three lines to classify trend state: price above the upper line signals an uptrend, price below the lower line signals a downtrend, and price between the lines is treated as non-trending. The document provides no equations, parameter guidance, chart examples, or backtest results, so it does not establish how robust these classifications are or how they perform across markets. It describes a trend-reading tool, not a complete entry, exit, or risk-management strategy.
Key ideas
- The indicator uses a configurable high-pass filter period and applied price.
- It seeks to separate higher-frequency price components from lower-frequency direction.
- Price above or below the outer lines is interpreted as an uptrend or downtrend.
- Price between the lines is classified as non-trending.
- The description provides no performance testing or complete trading rules.
