The Fibonacci retracement tool is widely used in modern trading—but where did it come from? If you’ve ever wondered who developed Fibonacci retracement and when it was introduced, you’re not alone.
Let’s explore the historical roots of this popular indicator, from its mathematical origin to its application in financial markets.
The Origins: Leonardo Fibonacci
The Fibonacci sequence was introduced by Leonardo of Pisa, also known as Leonardo Fibonacci, an Italian mathematician born around 1170 AD. He introduced this sequence in his book Liber Abaci (The Book of Calculation) in 1202.
The sequence goes like this:
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…
Each number is the sum of the two preceding numbers.
While Leonardo did not create the sequence (it was known in India earlier), he popularized it in Europe and introduced it to the Western world.
The Golden Ratio Connection
From this sequence, mathematical ratios such as 0.618 (61.8%), 0.382 (38.2%), and 0.236 (23.6%) are derived. These ratios are seen in nature, architecture, art—and now in trading.
But Fibonacci did not invent the retracement concept as used in modern technical analysis.
When Did Fibonacci Retracement Enter Trading?
Fibonacci retracement as a technical tool became popular in the late 20th century, especially with the rise of charting software and the broader adoption of technical analysis.
The actual application of Fibonacci levels in price charts is credited to technical analysts and traders—not to Fibonacci himself.
No single person is officially credited with the trading tool’s creation, but it evolved from a blend of mathematics, Dow Theory, and market psychology.
