About Fibonacci

What is Fibonacci.com?

Fibonacci.com is a platform specializing in the application of Fibonacci trading tools in the technical analysis of markets. We publish daily technical charts and information with the aim to highlight trade setups and improve the probabilities and success rate of trading markets. The site also offers an extensive history on the subject of Fibonacci, including the origins of the Fibonacci sequence, its quotient known as the Golden Ratio, and its various applications across science, nature, art, and mathematics.

Additionally, the site features a growing collection of resource materials, like book reviews, a free downloadable e-book, information on trading tools and investment research, and a trading glossary covering such topics and Fibonacci retracements and extensions.

A Little Background . . .

My first recollection of the Fibonacci sequence (0,1,1,2,3,5,8,13…) and the quotient of its successive numbers, phi (0.618), also known as the Fibonacci constant or the Golden Ratio, occurred in high school math class. Like pi (π) or Euler’s exponential constant, e, phi (φ) seemed meaningful only as a requirement for exams.

That phi persisted as an important mathematical concept through my engineering course of study in college was not particularly surprising. That it became a prevailing theme in a Humanities seminar on the artwork of Leonardo da Vinci, Michelangelo and the topic of what constitutes beauty, was so notable that I remember the class today, more than twenty years later. The notion that the Golden Ratio proposes an answer to the question of whether there is an objective measure of beauty has always been fascinating to me.

Later on, in various media, I casually noted references to the Fibonacci sequence in biology, geography, and other disciplines, but not until I took an earnest interest in commodities trading did I fully appreciate Fibonacci’s ubiquity. In technical trading, Fibonacci ratios serve as a useful indicator of likely support and resistance levels, and I have enjoyed success in my personal trading using these tools as a foundation for my process.

Master Fibonacci: The Man Who Changed Math

In 2018, I asked Shelley Allen to pen an introductory book on the origins and prevalence of the Fibonacci sequence in art, music, nature, and other disciplines titled “Master Fibonacci: The Man Who Changed Math,” available in paperback and Kindle on Amazon, as well as a free e-book download on this website when you sign up. It is my sincere ambition that the book – like this website – inspires an appreciation not only for the math but also for the man who propagated it: Leonardo Pisano, a.k.a Master Fibonacci. In this well-researched arrangement, with numerous references and over 100 citations, Allen offers the reader a concise overview of the subject along with breadcrumbs for continued learning. Along the way, the reader will learn how Roman numerals were replaced in Europe, and how the “Rabbit Problem,” among other examples, changed math as we know it.

As a trader, I personally find the prevalence of the Fibonacci sequence in our world to be both fascinating and mysteriously relevant to the behavior of markets. I hope you will agree.
