Using Fractal Graph Dimension to Classify Trend and Volatility States

Article MQL5 code base

Summary

The Fractal Graph Dimension Indicator is presented as a way to distinguish trending conditions from unstable, volatile conditions. It has three inputs: the calculation period, the applied price, and a threshold. Readings below the threshold are classified as trending and shown in red; readings above it are classified as volatile and shown in blue. This makes the threshold central to how the indicator labels market state.

The description traces the indicator to work discussed in a 2007 technical analysis publication and to an earlier procedure for estimating the fractal dimension of waveforms. It does not provide the formula, a recommended period or threshold, or guidance for choosing the applied price. Nor does it show empirical validation, asset-specific behavior, or a trading strategy based on the classifications. The indicator therefore supplies a regime-labeling concept, but the note alone cannot establish that its states are reliable or useful for forecasting or trade selection.

Key ideas

  • The indicator uses fractal graph dimension to label market conditions as trending or volatile.
  • It requires a calculation period, an applied price, and a threshold.
  • Values below the threshold are classified as trending, while higher values are classified as volatile.
  • The description cites prior technical analysis and waveform-estimation work but provides no formula or validation.
