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. In high frequency designs and mass production, however, many of these approaches involve complex feeding networks or precise structural modifications, increasing fabrication challenges and limiting scalability. Recent advances have attempted to reduce complexity by using passive parasitic elements, such as meander-shaped structures, which introduce a 90° phase shift in radiated fields20.

Why is PFE important for traders?
Section IV provides the results of fabrication and measurements, followed by Section V, which compares the proposed design with related works. The paper concludes with a summary of key findings and potential applications of the four-element CP dipole array antenna design. The simulated and measured impedance bandwidths (IBWs) for the proposed circularly polarized printed dipole array antenna are reported in Fig. Experimental results confirm that the array antenna achieves a wide impedance bandwidth of 41.12% (1.99–3.02 GHz), covering the WLAN and ISM frequency bands and making it well-suited for S-band satellite applications.
The polarized fractal efficiency indicator measures and reflects only what price has been doing in the past. For stock indices, the polarized fractal efficiency indicator testing found the maximum efficiency to be around 43%. Since markets are turbulent, nonlinear systems that are consequences of human beings interacting with each other, the behavior of the price is the perfect place to look for fractal structures. Beginners can learn to use the PFE effectively by seeking trading education from the right sources.
By looking at these fractals, traders and investors can understand if the market is getting more or less efficient, which helps them make smarter choices about when to buy or sell assets. The strength of the trend is measured by the position of the Polarized Fractal Efficiency (PFE) relative to the zero line. As a general rule, the further the PFE value is away from zero, the stronger and more efficient the given trend is. A PFE value that fluctuates around the zero line could indicate that the supply and demand for the security are in balance and price may trade sideways. At its core, the polarized fractal efficiency indicator represents a complex variation of a price velocity oscillator, where a slower period change in the closing prices is divided by a faster period average change in price.
In addition to strengthening surface current distribution, opening slots enabled the propagation of left-handed CP (LHCP) as well as right-handed CP (RHCP) radiation at distinct frequencies. As a result of this symmetric structure and feeding technique, RHCP was enabled and a wide axial ratio bandwidth was achieved, demonstrating effective CP characteristics for a variety of questrade review applications. This research, presents an innovative printed dipole array antenna that features a simplified yet effective feeding network using Wilkinson power dividers and microstrip lines as phase shifters.
Technical Analysis That Indicates Market Psychology
The price shows an upward trend if the PFE goes above zero and a downward trend if it drops below zero. The indicator was developed by author, engineer, programmer, and trader Hans Hannula. PFE uses something called fractals, which are patterns that look the same no matter how closely you look at them. If the patterns are getting clearer, it means the market is getting better at showing what’s happening, which is different from traditional models that just focus on whether prices reflect all available information. So, PFE gives traders and investors a new tool to understand the market by looking at its patterns, not just its information. The Polarized Fractal Efficiency (PFE) indicator draws on Mandelbrot and fractal geometry to illustrate the efficiency of how pricing moves between two points over time.
- A higher number means the patterns are clearer and the market is more efficient.
- When the PFE is far above the zero line, it indicates an uptrend, and when it is far below the zero line, it indicates a downtrend.
- The future prospect of PFE in trading is mass adoption in algorithmic trading.
- Securities with a PFE greater than zero trend up, while a perusing of under zero shows a descending trend.
As part of recent studies, printed dipole antennas have been adapted to achieve circular polarization. The design in12achieves circular polarization by combining LP-printed itrader review dipole antennas (PDAs) with a frequency-selective surface (FSS) which functions as a linear-to-circular polarization converter (LCPC). In this structure, an FSS converter has been specifically selected to convert LP waves into CP at specific frequency bands, achieving a 3-dB axial ratio bandwidth (ARBW) for each band. According to the measurements, this antenna has a peak RHCP gain of 14.16 dBic. Additionally, the antenna has a stable and unidirectional radiation pattern when it comes to RHCP radiation.
Circularly polarized printed dipole array antenna configuration
The antenna’s impedance bandwidth of 1.99–3.02 GHz comfortably encompasses the 2.4 GHz band used in WLAN, commonly known as Wi-Fi. This band is widely utilized for home and enterprise wireless networking, allowing the antenna to be effectively applied in WLAN access points, routers, and network extenders. Also, the CP design improves signal resilience against polarization mismatches that may arise due to the orientation of mobile or handheld devices. This can reduce signal fading and improve reception quality in environments where devices frequently move or change orientation.
Polarized Fractal Efficiency (PFE) Definition
- This can reduce signal fading and improve reception quality in environments where devices frequently move or change orientation.
- By looking at this number over time, traders can see if the market is getting better or worse at showing what’s happening.
- In compact, high-frequency applications in which component spacing is restricted, meander-shaped parasitic elements and sequentially rotated feeding networks still pose phase alignment challenges, despite their advantages.
- This two-step approach, with a semi-fractal dipole structure followed by stair-shaped parasitic elements, achieves an efficient and compact circularly polarized antenna design.
- It’s like looking at a puzzle and seeing how the pieces fit together in a way that keeps happening over and over.

If the market is predominantly range-bound, the indicator can show that too, as the values would cluster around the zero line. By now, you know the basics of the indicator, so let’s show you a strategy that is complete with trading rules. The switch features a premium aluminum faceplate and silicone-sealed door with keyed access.
Each step introduces an incremental phase shift (Δϕ ≈ 18° at 2.4 GHz) due to the spatially staggered current induction along the stair structure. The cumulative effect of all five steps yields the target 90° phase difference (5 × 18° ≈ 90°) between orthogonal field components (Ex and Ey). Another way experts can use Polarized Fractal Efficiency to optimize systems is by predicting future market trends.
Simulated and measured normalized RHCP/LHCP radiation patterns for the proposed array antenna at 2.4 GHz frequency. To further demonstrate the role of the stair-shaped parasitic elements in producing circular polarization, the surface current distribution on these elements at 2.4 GHz is depicted in Fig. Thus, CP antennas have become an integral part of satellite communication, radar, and wireless networks that require exness broker reviews high signal reliability3,4. Due to their superior performance and resilience, CP antennas have gained considerable attention within the modern communication system. To analyze Polarized Fractal Efficiency, traders and analysts use special software and tools that can look at market data and find repeating patterns. One popular tool is trading platforms like MetaTrader 4 or 5, which have built-in indicators and scripts that can calculate the Polarized Fractal Efficiency Index.
As a rule of thumb, traders ought to buy to cover all short positions after the indicator forms another base. The PFE compares fairly well with other trading indicators, as it shows several aspects of the price action. It tells you whether the market is trending or consolidating, and when the market is in a trend, it could also show the direction of the trend and its strength and efficiency. This is unlike other indicators that only tell you about the trend direction (moving averages) or the trend strength (like the ADX) alone. The indicator uses the current price and price at an N-period and finds the square root function. By dividing the length of the line that is 100% efficient, it gives a measure of fractal efficiency.

The more linear and efficient the price movement, the shorter the distance the prices must travel. Also, in an already-established major trend, traders can use the PFE to know when a pullback has ended and the price is about to reverse to continue another impulse swing in the trend direction. So, in an uptrend, when there is a pullback and the PFE reverses from a below-zero level, it could be a signal to buy the next upswing.
If you can see the smaller pictures more clearly over time, then the big picture, or the market, is getting better at showing what’s happening. Traders and investors use this information to decide when to buy or sell assets. By understanding if the market is getting more or less efficient, they can make smarter choices about their investments. Since no indicator is foolproof, setting appropriate stop-loss levels is crucial. Traders can place stops at recent swing highs/lows or based on volatility levels to mitigate risks.
Advanced mathematical models used in Polarized Fractal Efficiency research often include complex algorithms that look at how patterns in the market repeat over time. One common model is the use of fractal geometry, which helps to understand these repeating patterns no matter how closely you look at them. Researchers use this to see if the market is getting better or worse at showing what’s happening. They also use time series analysis, which looks at how data changes over time. This helps them see if the patterns are getting clearer or blurrier, which tells them about the market’s efficiency. In the world of Polarized Fractal Efficiency, fractals are like repeating patterns that you can see in the market.
