Polarized Fractal Efficiency (PFE)


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.


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.


PFE(int period)
PFE(IDataSeries inSeries, int period)
PFE(int period)[int barsAgo]
PFE(IDataSeries inSeries, int period)[int barsAgo]

Return value


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.


inSeries Input data series for the indicator

period Number of bars included in the calculations



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