To achieve the necessary phase rotation, microstrip lines are employed as phase shifters. In this configuration, a microstrip line with an additional half-wavelength path length introduces a 180° phase shift, while lines with an additional quarter-wavelength length introduce a 90° phase shift. By strategically combining these microstrip lines with the Wilkinson power dividers, a sequential rotation feeding network is created. This setup produces four output signals with equal amplitudes and phase differences of 0°, 90°, 180°, and 270°, essential for generating circular polarization in the array. The CP-PDA elements are also arranged with a physical rotation of 90° between each adjacent element. This combination of phase and physical rotation ensures that the radiated fields from each CP-PDA element reinforce one another, thereby enhancing the purity and consistency of the circular polarization across the array.

The proposed design in this work, also includes a fractal-inspired dipole arm and stair-shaped parasitic elements, allowing precise control of phase and amplitude across orthogonal components. This configuration for the antenna, enhances circular polarization characteristics while retaining a compact, low-profile form factor, minimizing the need for complex feeding networks. Also, Section III in this study, presents the proposed dipole array structure with a robust feeding network.
The PFE indicates market trends when its values are moving steadily away from the zero line. With its values ranging from -100 to +100 and zero being the midline, the farther away from zero the value is, the stronger the trend. Cover-Pools automatic pool cover systems have two available premium fabric options – Quad-Core™ Laminated Fabric or Pro-Coat™ Coated Fabric. Developed by Hans Hannula, the Polarized Fractal Efficiency (PFE) indicator was described in the January 1994 issue of Technical Analysis of Stocks & Commodities magazine. In case the PFE reading is below zero, this suggests there is a bear trend. In case the PFE reading is above zero, this suggests there is a bull trend.
If price begins to enter into congestion in the vicinity of zero, close the position and wait for a new maximum efficiency entry. Finally, if we attach a plus sign when the move is down and a minus sign when the move is up, we have polarized fractal efficiency. The PFE indicator created a buy signal in American Tower (AMT) on July 30, 2019, when it switched from its base close to zero. In this way, the indicator created a signal to close positions when it arrived at its top over zero on Aug. 12, 2019. The polarized fractal productivity indicator was developed by creator, engineer, developer, and trader Hans Hannula. The thought was first referenced in 1994 in the January issue of Technical Analysis of Stocks and Commodities magazine.

Figure 8 provides photographs of the fabricated prototype, along with images documenting the testing process conducted in the antenna laboratory. These tests were performed to evaluate the antenna’s real-world performance and verify the simulated characteristics, ensuring consistency across both simulated and experimental results. Simulated and measured omnidirectional peak gain for LP-PDA and RHCP/LHCP gains for CP-PDA. The overlaps ensure smooth current transitions between steps, minimizing discontinuities that could degrade polarization purity.
By using regression, they can see which factors make the market more or less efficient. Additionally, machine learning models are becoming more popular in this field. These models can learn from past data to predict how clear the patterns will be in the future. By using these advanced mathematical models, researchers can get a better understanding of Polarized Fractal Efficiency and how it can be used to make smarter decisions in the market.
Our website is focused on major segments in financial markets – stocks, currencies and commodities, and interactive in-depth explanation of key economic events and indicators. The safe way to use it is to trade during the times of maximum efficiency, and to enter by following price action with a trailing stop. Such paradigm shift led to the development of polarized fractal efficiency (PFE) concept. It gives us a better roadmap to trading by concentrating on the current market behavior, which is a sum of the individual fractal behavior of traders. Its reason is richly caught through fractal calculation for financial market applications. Hannula’s and Mandelbrot’s research has brought the genuinely necessary study of turbulent systems to financial systems.

- Additionally, it is worth noting that the antenna can be reconfigured to LHCP by rotating the stair-shaped parasitic elements by 90°, providing flexibility in circular polarization orientation.
- A PFE value that fluctuates around the zero line could indicate that the supply and demand for the security are in balance and the price may trade sideways.
- As a concept, fractal efficiency has been found to be very useful in trading stocks, commodities and currencies.
- Hannula introduced Polarized Fractal Bands (PFB)—dynamic support and resistance levels derived from PFE values.
By using these tools, analysts can measure how efficient the market is and see if the patterns are getting clearer or blurrier. Polarized Fractal Efficiency uses these fractals to measure how well the market is working. If the fractals are becoming clearer over time, it means the market is getting better at showing what’s happening. On the other hand, if the fractals are getting less clear, it means the market is getting worse at showing what’s happening, and the picture is becoming blurrier.
Can PFE be used for short-term trading strategies?
This continuity preserves the amplitude balance between Ex and Ey, essential for high-quality CP generation. Polarized Fractal Efficiency can help with sustainability and resource management by making markets work legacyfx review better. For example, if a company sees that the market is getting better at showing what’s happening, they might be able to predict what resources they’ll need in the future.
And it could also indicate the direction of the trend if present, as well as the strength and efficiency. When the PFE values are far broker finexo above or below the zero line, it could mean that there is a trend — with values above zero indicating an uptrend and values below zero indicating a downtrend. The PFE indicator measures market efficiency by showing which direction the price is trending and the strength of the price action. Its values being above or below the zero line indicates the direction of the trend — above the zero line indicates an uptrend and below the zero line indicates a downtrend.
The higher the value, the more efficient, ”trendier” the movement to the upside is. If the PFE reading is in proximity to zero, this means that market movement is choppy and less efficient.

Hannula introduced the PFE in Technical Analysis of Stocks & Commodities magazine, applying concepts from mathematics, market cycles, and chaos theory to price behavior. Traders use this indicator to gauge trend strength, identify reversals, and refine entry and exit points.

Technical Analysis
The main contribution of this study is that the feeding network consists of unsensitive elements and provides a reliable performance when used with new printed dipole designs with stair-shaped parasitic elements. Simulated and measured axial ratio bandwidths for the proposed circularly polarized printed dipole array antenna is reported in Fig. The array antenna exhibits a wide axial ratio bandwidth of 35.02% (2.12–3.02 GHz), which effectively maintaining circular polarization across a significant portion of its operating frequency range. 3 shows the simulated and measured 3-dB axial ratio bandwidths (ARBWs) for both the LP-PDA and CP-PDA configurations.
Polarized Fractal Efficiency (PFE): what chaos can do to improve your trading
If we divide the length of the straight line (100% efficient) by the length of the squiggly line, we have a measure of fractal efficiency. It would be reasonable to propose that the nature of any pattern that is the result of human interaction in markets should also be fractal. The profound meaning of this observation suggests that markets are nonlinear in nature, and just as Euclidian approach is incapable of measuring the coastline, neither it can accurately predict the market behavior. Mandelbrot also discovered a similarity between cotton prices and the fractal number of Mississippi River, which held throughout the century of floods, draughts and wars.
