This free indicator helps traders analyze market volatility and identify potential turning points, enabling more informed trading decisions.

Unlike many standard indicators, the FDI Indicator goes beyond simple price tracking. It calculates the fractal dimension of a price series to assess the strength and structure of market trends. This approach provides deeper insight into price movements and helps traders identify when a trend is likely to continue or reverse.

How the Fractal Dimension Index Works

The Fractal Dimension Index operates by analyzing the complexity of price movements using mathematical formulas. It produces an FDI line that reflects market volatility and Trend Strength. Traders can interpret this line as follows:

FDI line above the threshold: Suggests a potential uptrend and stronger market momentum

By monitoring the FDI line, traders can detect trend reversals early and make strategic entry or exit decisions.
