Fractual Dimension

The Fractual Dimension chart study is displayed at the bottom of the graph and has a range between 1 and 2. A Fractual Dimension close to 1 indicates a prominent price level trend, i.e. a straight line. Conversely for a Fractual Dimension value close to 2.

Old Help File:

"The Fractal Dimension study measures the dimensionality of the signal over time. It is a measure of how "complicated" a self-similar figure is. Mathematically, it equates to

FD(n) = log(PathLength) / log(AbsoluteLength)

where PathLength is the sum of all distances within the signal between the current point and n points ago,

and AbsoluteLength is the direct distance between the current point and n points ago.

The Fractal Dimension will tend toward 1.0 when the signal approaches a straight line, and increases along with its volatility. It is useful in spotting consolidations ahead of a price move.
