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
Zero-Lag Fractal KdV Smoothing computes a weighted average between the current close price and the prior filtered value, where the weights depend on the C Parameter and Alpha fractal dimension input. The resulting smooth line is plotted directly on the price chart. This technique reduces lag in trend signals while preserving important market structure. The main settings adjust smoothing strength through the C Parameter and Alpha values.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
