Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
Excalibur Ehlers AutoCorrelation Periodogram Modified plots a spectral heatmap and dominant cycle measurements in a separate indicator pane to help traders identify prevailing market cycles. Key settings allow customization of high-pass and low-pass filter periods, autocorrelation lag, power thresholds, heatmap contrast, and dominant cycle smoothing algorithms.
- Roofing filter with selectable high-pass order
- Autocorrelation periodogram spectral analysis
- Dominant cycle tracking and filtering
- Customizable spectral heatmap contrast and color scheme

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
