Fibonacci retracement is a powerful tool used by traders and analysts to identify potential reversal levels in financial markets. Rooted in a mathematical sequence discovered centuries ago, it has evolved into a cornerstone of technical analysis—especially in volatile markets like cryptocurrencies and stock indices such as the Nasdaq.
This guide explores the origins of the Fibonacci sequence, its application in chart analysis, and how traders use retracement and extension levels to forecast price movements. Whether you're analyzing Bitcoin trends or broader market cycles, understanding Fibonacci can give you a strategic edge.
The Legacy of Leonardo Pisano Bigollo (Fibonacci)
Leonardo Pisano Bigollo, better known as Fibonacci, was a pioneering Italian mathematician of the 13th century. He is widely regarded as one of the most talented mathematicians of the Middle Ages. His greatest contribution came with the publication of Liber Abaci in 1202, where he introduced the Western world to the Hindu-Arabic numeral system—what we now know as Arabic numerals.

Within this groundbreaking work, Fibonacci also described a number sequence that would later bear his name:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on—each number being the sum of the two preceding ones.
What makes this sequence remarkable is the ratio between consecutive numbers. As the sequence progresses, the ratio of any number to the next approaches 0.618, while the inverse ratio approaches 1.618—a value known as the Golden Ratio or Phi (φ).
This mathematical phenomenon appears repeatedly in nature—from the spiral of a nautilus shell to the arrangement of sunflower petals—and has been used by artists and architects for centuries to achieve aesthetic harmony.
The Golden Rectangle and the Golden Ratio
A golden rectangle is one whose side lengths are in the proportion of 1.618:1. If you divide any Fibonacci number by its predecessor (e.g., 89 ÷ 55 or 21 ÷ 13), the result approximates 1.618—the "magic number" often compared to π (pi) in significance.
This ratio forms the foundation of Fibonacci retracement levels used in trading:
- 23.6%: Derived from dividing a number by the one three places ahead.
- 38.2%: Obtained by dividing a number by the one two places ahead.
- 61.8%: The most significant level, from dividing a number by its immediate successor.
- 78.6%: The square root of 0.618, commonly included in modern platforms.
Although 50% and 100% are not Fibonacci ratios per se, they were incorporated into technical analysis by W.D. Gann and are now standard reference points due to their psychological and structural relevance in market movements.
Applying Fibonacci in Technical Chart Analysis: Retracement and Extension
In trading, Fibonacci retracement helps predict how much of a prior price move might be retraced before the trend resumes. It’s especially useful in markets characterized by cyclical behavior—two steps forward, one step back.
Traders apply Fibonacci levels during pullbacks by identifying:
- A clear low (point A)
- A subsequent high (point B)
- The retracement (point C) against that move
Using these points, key Fibonacci levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) are plotted to anticipate where support or resistance may emerge.
Fibonacci extensions (127.2%, 144.4%, 161.8%) go beyond the original swing high/low and help project potential profit targets during trend continuation phases.
These tools are often combined with other technical patterns like:
- Elliott Waves
- Head and Shoulders
- Triangles and rectangles
- Double tops/bottoms

Real-World Application: Fibonacci in Bitcoin and Nasdaq Trends
One of the most compelling examples of Fibonacci’s predictive power lies in Bitcoin’s price action following its all-time high in late 2021.
On November 8, 2021, analysts applied Fibonacci retracement from the peak (~$69,000) down to a critical support zone between **$28,000–$30,000 (marked as the 100% level). The zero point was set at the ATH, with extension levels drawn at 127.2%, 144.4%, and 161.8%**.
The expectation? A retracement to either the 61.8% or 50% level—classic zones for bullish reversals or consolidation.
By March 2022, after further refinement using Elliott Wave analysis, a new wave structure emerged:
- Wave 1 ended near the 61.8% retracement
- Wave 2 retraced to around 38.2%
- A projected bearish Wave 3 aimed toward $17,800 (the 100% retracement level)
Later projections suggested deeper declines:
- A drop to $18,500 (78.6% level)
- Followed by a breakdown below $17,800**, targeting **$4,300 (127.2% extension)
While Bitcoin didn’t hit $4,300 immediately, it did fall close to **$15,500** by late 2022—validating the strength of Fibonacci-based forecasts.
Chartists also noted bearish patterns like the “giant M” and “cup with handle,” reinforcing downside momentum.
Learning from History: Market Cycles and Fibonacci Patterns
To understand today’s market dynamics, we must look back at historical cycles—such as the dot-com bubble burst in 2000.
The Nasdaq’s bull run from 1995 to 2000 lasted about five to six years—a timeframe mirrored in recent tech rallies. Its subsequent bear market bottomed around 2002–2003 after a roughly two-and-a-half-year decline.
Applying Fibonacci retracement from the peak (~5,048 points) down:
- Wave 1: Retraced 61.8% (~3,270)
- Wave 2: Rebounded to 38.2% (~3,894)
- Wave 3: Crashed to 100% (~5,000 → ~2,260)
- Wave 4: Bounced to 78.6% (~2,826)
- Wave 5: Final drop to 161.8% (~627)
This near-perfect alignment shows how market psychology repeats over decades.
Using similar logic today—with Nasdaq having enjoyed over a decade of growth—analysts project a multi-year correction phase:
- Potential drop to 9,500–8,500 points
- Long-term target between 2,000–62 points (127.2%–144.4% extension)
If history rhymes, Bitcoin could face extended downside pressure—possibly falling below $4,000—before entering a new accumulation phase.
Patience and cycle awareness remain essential virtues for long-term investors.
Frequently Asked Questions (FAQ)
What is Fibonacci retracement used for?
Fibonacci retracement identifies potential reversal levels during a price pullback within a larger trend. Traders use it to find entry points or set stop-loss orders based on key ratios like 61.8% and 38.2%.
Are Fibonacci levels always accurate?
No tool guarantees accuracy. However, Fibonacci levels often align with psychological and structural market turning points because many traders watch them—creating self-fulfilling support/resistance zones.
How do I draw Fibonacci retracement on a chart?
Select the lowest point (A) and highest point (B) of a price swing. Most trading platforms automatically plot retracement levels (23.6%, 38.2%, etc.). Adjust based on confirmed price reactions.
Can Fibonacci predict exact price targets?
It doesn’t predict exact prices but provides probabilistic zones where reversals or continuations are more likely. Combining it with volume, momentum indicators, or candlestick patterns improves reliability.
Is Fibonacci applicable to all markets?
Yes—stocks, forex, commodities, and especially cryptocurrencies exhibit Fibonacci-like patterns due to recurring human behavior in buying and selling cycles.
Why include 50% if it's not a Fibonacci ratio?
Though not derived from the sequence, 50% is a psychologically significant midpoint widely adopted by traders since the early 20th century—popularized by W.D. Gann.
Final Thoughts: Blending Technical and Fundamental Analysis
While there's no inherent reason why asset prices should follow Fibonacci ratios any more than geometric sequences, their widespread use gives them practical value.

Technical analysts act as market psychologists—interpreting crowd sentiment through price action. In contrast, fundamental analysts serve as "market meteorologists," forecasting conditions based on economic data like inflation, interest rates, and employment figures.
Neither approach guarantees success—but combining both enhances decision-making accuracy.
Fibonacci retracement won’t replace due diligence or risk management, but when used wisely alongside other tools, it offers a structured way to anticipate market moves and position yourself ahead of major shifts.
Remember: Markets move in cycles—not randomly—and understanding those rhythms is key to long-term success.
