Overview
The script visually highlights trend conditions through dynamic ribbon filling, optional difference histogram bars, and overbought or oversold breakout fills. It also plots circle shapes upon MFI and signal line crossovers and provides optional background coloring based on whether the MFI is above or below the 50 middle level. Key settings include calculation lengths, source price, and customizable threshold levels.
- Money Flow Index calculation with EMA signal line
- Optional MACD-style difference histogram
- Overbought and oversold breakout zone highlights
- MFI and signal crossover marker shapes
- Middle line 50-level crossover background shading

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.
