Description:
PFE (Polarized Fractal Efficiency)

Formula Parameters:

Notes:

The Polarized Fractal Efficiency (PFE) indicator measures the efficiency of price movements by drawing on concepts from fractal geometry and chaos theory. The more linear and efficient the price movement, the shorter the distance the prices must travel between two points and thus the more efficient the price movement.
