The Polarized Fractal Efficiency (PFE) indicator is designed for identifying trends.
There are four input parameters:
PFE = EMA(B, MA period)
If Close > Close[Slow ROC period]:
B = 100.0 * Z
B = -100 * Z
Z = Sqrt(LongROC * LongROC + 100) / (Sqrt(ShortROC * ShortROC+1) + PDS) LongROC = 100.0 * (Close / Close[Slow ROC period]-1) ShortROC = 100.0 * (Close / Close[Fast ROC period]-1)
