Polarized Fractal Efficiency
Polarized Fractal Efficiency was authored by Omega Research 1997. The PFE uses price on several past price bars. They are powered, rounded, sqaure rooted, feed their past values and finally formed into an oscillator. The user may change the input (close) and period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using Polarized Fractal Efficiency
Adjust the top and bottom guides to control the quantity and quality of the trading signals. If the ema peaks above the top guide a sell signal will be generated. Conversely, if the ema troughs below the bottom guide a buy signal will be given.
The zero line divides the bears above from the bulls below.
