Learn how the Polarized Fractal Efficiency (PFE) indicator helps traders and investors identify strong market trends and reversals with precision.
Introduction
The Polarized Fractal Efficiency (PFE) indicator, developed by Hans Hannula in 1994, is a powerful tool for measuring the efficiency of price movements in financial markets. Based on fractal geometry, it assesses how smoothly prices trend over a given period. The PFE oscillates between -100 and +100, where a high positive value signals a strong uptrend, and a high negative value indicates a strong downtrend. Values near zero suggest a choppy or ranging market.
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.

How to Use the Polarized Fractal Efficiency Indicator
Identify Trends
The PFE provides a clear visualization of price efficiency:
- PFE above zero – Strong uptrend
- PFE below zero – Strong downtrend
- PFE near zero – Market lacks clear direction
A greater deviation from zero suggests a more efficient trend.
Optimize Settings for Different Timeframes
Hannula recommends adjusting PFE settings based on the timeframe:
- Daily Charts – 10-period PFE with 5-period smoothing
- Weekly Charts – 5-period PFE with 3-period smoothing
- Monthly Charts – 20-period PFE with 10-period smoothing
Traders can customize these values to fit their trading strategy.
Trading Signals Based on PFE
Hannula suggests the following strategies:
- Enter Long: When PFE crosses above zero from below (trend reversal to bullish).
- Enter Short: When PFE crosses below zero from above (trend reversal to bearish).
- Hold Long: When PFE reaches a new high above zero (strong uptrend).
- Hold Short: When PFE reaches a new low below zero (strong downtrend).
- Exit Long: When PFE peaks above zero and starts declining (trend exhaustion).
- Exit Short: When PFE bottoms below zero and starts rising (trend exhaustion).
- Take Profits: When PFE returns to zero (trend losing efficiency).
Enhancing Accuracy with Additional Tools
- Moving Averages: Applying a moving average to PFE smooths fluctuations and helps confirm trends.
- Threshold Levels: Setting upper and lower thresholds (e.g., ±10) helps distinguish between trending and ranging markets.
- Divergence Analysis: A bullish divergence occurs when prices make lower lows while PFE makes higher lows, signaling a potential trend reversal. A bearish divergence is the opposite.
- Crossover Strategy: A buy signal occurs when PFE crosses above its moving average, and a sell signal when it crosses below.
Combining PFE with Other Indicators
To improve signal reliability, traders should combine PFE with:
- Price action analysis to confirm support and resistance levels.
- Trendlines and moving averages to validate trends and breakouts.
- Other momentum indicators like RSI or MACD for additional confirmation.
Managing Risk with Stop-Loss Levels
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 Techniques: Polarized Fractal Bands (PFB)
Hannula introduced Polarized Fractal Bands (PFB)—dynamic support and resistance levels derived from PFE values. These bands can help identify breakout points, continuation patterns, and trend reversals.
Advantages & Limitations of PFE
Advantages
- Versatile: Adaptable to various timeframes and market conditions.
- Noise Reduction: Uses smoothing to filter out market noise.
- Clear Trend Signals: Helps traders easily identify strong trends and reversals.
Limitations
- Lagging Nature: The smoothing process can delay signals.
- False Signals in Sideways Markets: PFE may generate unreliable signals in choppy conditions.
- Sensitive to Sudden Price Moves: Extreme price swings can distort readings.
Conclusion
The Polarized Fractal Efficiency indicator is a valuable addition to any trader’s toolkit, providing insights into market trends, reversals, and efficiency. By fine-tuning settings, combining PFE with other technical indicators, and managing risk appropriately, traders can enhance their decision-making process.
