- No new phase changes on the 11 currency pairs that I follow.
- USD/CAD: Polarized fractal efficiency (pfe) line crosses below zero.
- AUD/JPY: Pfe line reverses into an uptrend, crosses above 50.
PPS/PFE Analytical Tools
The analysis uses the daily Person's Proprietary Signal (pps), developed by John Person, and the weekly Person's Pivot, which he also developed.
These are black box signals -- the "proprietary" means that Mr. Person knows how they work under the hood, and I don't. But they have shown a fair degree of success in identifying good entry and exit points, and I find them useful.
For confirmation, the analysis uses an indicator called the polarized fractal efficiency (pfe) technical tool. It uses the fractal math of Benoit Mandelbrot to measure how efficiently move between levels. The higher the efficiency, the more directional the price trend.
The math for the pfe is public knowledge, but it is well above my math knowledge, and so to me is also a black-box signal.
This is a relatively new technical tool, based on fractal math. Investopedia has only a cursory explanation. Wikipedia is silent on the subject. ThinkOrSwim has a fuller explanation.
PPS/PFE Trading Rules
These rules are very preliminary. I’m still trying to figure out how the polarized fractal efficiency signal works.
When Person’s Proprietary Signal (pps) is in bull phase, enter when the polarized fractal efficiency (pfe) turns to an uptrend (pfe trend). A pps signal and pfe uptrend have less strength but greater upside potential when the pfe location (pfe loc) is below -50, and greater strength but less upside potential when the pfe location is above +50.
When the pps in in bear phase, enter when the pfe trend turns down. The set up has less strength but greater downside potential when the pfe loc is above +50, and greater strength but less downside potential when the pfe loc is below -50.
The target is the weekly Person’s Pivot level in the direction of the trend, determined by the pps.
The question is how to treat the pfe when it has flatlined at the top of its range, above 100. My preliminary observations are that the price by then has had a large upward run and tends to present a picture of exhaustion. However, by the description of the pfe, a high level should indicate a continued strong trend.
This is something that i’ll figure out as I go along.
