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

McDonald's Pattern [LuxAlgo] plots fries above top points and hamburgers below bottom points, then connects selected points with smooth lines created through cubic interpolation. Colored areas fill the range between minimum and maximum values, while a McDonald's score quantifies pattern strength based on deviation from center. Users can adjust length, line colors and widths, area display, and score visibility. All elements plot directly on the price chart. It repaints the visual elements on every bar.

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