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
Quadratic Surface Fit — Conic Branch Extractor classifies the resulting conic sections into ellipses, parabolas or hyperbolas to extract and plot curved polylines representing the branches directly on the price chart. Mean, plus-one-sigma and minus-one-sigma horizontal slices are optionally shown alongside the branches. Inputs control lookback length, polyline step size, source selection, slice visibility, curvature and line styling. The script draws solely on the price chart without separate panes.

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.
