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
Up to three FLD periods can be set manually or chosen automatically from the chart timeframe, with offsets, line widths and transparency for each. A composite line combines the selected waves, and optional markers show expected troughs and peaks with a percentage tolerance. It is a cycle visualisation tool and gives no entry or exit rules.
- Sine waves for three FLD periods
- Composite wave line
- Auto period by chart timeframe
- Expected trough and peak markers
- Adjustable wave height and offsets

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.
