This unit introduces Fibonacci retracement, a widely used technical analysis tool based on ratios derived from the Fibonacci sequence — a numerical pattern first introduced to Western mathematics by Leonardo of Pisa (Fibonacci) and later applied to financial markets by analysts including Ralph Nelson Elliott.
This overview introduces four areas covered in this unit: the difference between retracement and extension, commonly used levels, combining Fibonacci with support/resistance, and avoiding decisions based on Fibonacci alone.
This is general educational content. As one source (Charles Schwab) explicitly notes, no technical tool, including Fibonacci retracement, can reliably predict future price movement.
What Is the Fibonacci Sequence?
The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, and so on. As the sequence progresses, the ratio between consecutive numbers converges toward approximately 1.618, known as the golden ratio, and its inverse, approximately 0.618.
From Mathematics to Charts
Various ratios derived from this sequence — such as dividing a number by the one two places to its right, or by the very next number in the sequence — produce the percentage levels used in Fibonacci retracement tools, explored in detail in this unit's second lesson.
What's Covered in This Unit
- Retracement vs extension — two related but distinct Fibonacci tools.
- Common levels — the specific percentages widely used in practice.
- Combining Fibonacci with support/resistance — connecting to the earlier Price Action & Structure group.
- Avoiding 'single-tool' decisions — an essential closing perspective.
🔖 Summary
Fibonacci retracement is built on ratios derived from the Fibonacci sequence, including the golden ratio (approximately 1.618) and its inverse (approximately 0.618), applied to financial charts to identify potential areas of interest during a price pullback. This unit covers the distinction between retracement and extension, commonly used levels, combining Fibonacci with support/resistance, and the importance of not relying on Fibonacci alone.
Frequently Asked Questions
What is the Fibonacci sequence?
A series of numbers where each number is the sum of the two preceding numbers (0, 1, 1, 2, 3, 5, 8, 13...), with the ratio between consecutive numbers converging toward the golden ratio, approximately 1.618.
Who first applied Fibonacci ratios to financial markets?
Analysts including Ralph Nelson Elliott applied ratios derived from the Fibonacci sequence to market analysis.
Does this unit suggest Fibonacci can predict future prices?
No, this content explicitly notes that no technical tool, including Fibonacci retracement, can reliably predict future price movement.
How does this unit connect to earlier groups?
It builds directly on the support and resistance and trend structure concepts from the Price Action & Structure group.
