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

Adaptive Spectral Forecast analyzes a lookback window of 144 bars by default, extracts up to five dominant cycles, and projects a forecast line 55 bars ahead with confidence bands. Buy and sell signals can be limited to the direction of a smoothed trend, and reversal dots and a fitted historical curve can be shown. The forecast is redrawn as new bars arrive, so it changes over time and is only a projection.

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.
