Polarized Fractal Efficiency (PFE)
Description
Hans Hannula developed the PFE, which is categorized as a momentum indicator. It uses the methods of fractal geometry and chaos theory to determine the price efficiency of the movements.
Interpretation
When the PFE zigzags around the zero line, no trend is present. If the PFE is equally formed and running above the zero line, the market is in an uptrend. The higher the value, the stronger the uptrend.
Usage
PFE(int period)
PFE(IDataSeries inSeries, int period)
PFE(int period)[int barsAgo]
PFE(IDataSeries inSeries, int period)[int barsAgo]
Return value
double
When using this method with an index (e.g. PFE(20)[int barsAgo] ), the value of the indicator will be issued for the referenced bar.
Parameters
inSeries Input data series for the indicator
period Number of bars included in the calculations
Visualization

Example
//Output for the value of the Polarized Fractal Efficiency (PFE)
Print("The current value for the PFE is: " + PFE(20)[0]);
