MFI-Based Forex System Design: Reversal, Trend, and Divergence Rules

Summary

This article teaches the Money Flow Index (MFI) and offers several basic ways to turn it into systematic signals. MFI combines typical price and volume to estimate buying and selling pressure, with a calculation based on positive and negative money flow over a lookback period. The article explains the calculation conceptually and shows how the built-in indicator can supply values for an automated system.

Its examples include interpreting low and high readings as oversold and overbought, using mid-range thresholds for buy or sell signals with separate take-profit levels, and comparing changes in MFI with price highs or lows to flag possible trend confirmation or divergence. It also outlines building signal logic in MQL5. The document is aimed at beginners learning indicator use and coding, not at establishing a robust edge: it supplies no backtest results, and cautions that rules may need optimization or combination with other tools. Its examples should be independently tested before use, since a small set of thresholds may not suit every instrument or market condition.

Key ideas

• MFI uses price and volume to represent buying and selling pressure.
• The article describes threshold rules for identifying possible overbought and oversold conditions.
• Separate MFI levels are proposed for entry and take-profit signals in rising and falling conditions.
• Comparing MFI changes with price highs or lows can suggest trend confirmation or divergence.
• The example systems are educational and require independent testing and possible adjustment.
