Updated Version with request for NDBMFB for swingHL, when "H" or "L" text appears it refers to the previous fractal in the series, as pinescript doesnt support dynamic offsetting, added a few more goodies :p
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.
Looking for something other than a moving average to help determine not only a trend's strength, but also it's direction? Try PFE!
PFE was developed by Hans Hannula that was invented to determine price efficiency over a user-defined time period.
The Polarized Fractal Efficiency indicator is, in the essence, an exponentially smoothed ratio of the length of two...
