What is Fibonacci retracement? Trading Minute

A thirteenth-century accounting monk on your charts. Leonardo of Pisa, known as Fibonacci, published in 1202 a famous sequence of numbers, where each term is the sum of the two preceding ones. Eight centuries later, millions of traders draw Fibonacci retracements on their charts, often at the same points as classic support and resistance levels. Superstition or serious tool? A bit of both, and that's precisely what makes it interesting.

Fibonacci retracement, definition and how to use it

From the Fibonacci sequence comes a fetish ratio, approximately 0.618, the famous golden number. The Fibonacci retracement tool applies this ratio to charts. Take a large movement, from the low point to the high point, and divide it into levels at 23.6%, 38.2%, 50%, 61.8%, and 78.6%. The idea is simple. After a strong rise, a correction often stops at one of these levels, and after a crash, a rebound frequently struggles against it.

Why would this work? There’s no physical law behind it. But millions of participants look at the same levels, place their orders there, and the belief partially self-fulfills. A meeting point rather than a prophecy. The 61.8% remains the star of the show, to the point that traders have nicknamed it the golden pocket, alongside the 65% level.

Case study: the peak of ETFs in January 2024, right at 0.618

Get out the calculator. The great bear market of 2022 took Bitcoin from its peak of $68,982 to a low of $15,479. The 61.8% retracement of this drop is therefore around $48,500. On January 11, 2024, the day of the launch of Bitcoin spot ETFs, the price peaked at about $49,000 before dropping nearly 10% the next day, as reported by CoinDesk, and about 20% in the following weeks.

The ETF euphoria crashed just a few hundred dollars from the level that any Fibonacci tool had been showing for a year. A partial coincidence, no doubt, the sell-off on the news did most of the work. Nevertheless, thousands of traders had this threshold in their sights. The level didn’t cause anything; it served as a rallying point for profit-takers. The meeting was written on the charts.

Using Fibonacci as a retail trader, without mysticism

The proper use boils down to one rule. A Fibonacci level is never valuable alone; it is valuable when it coincides with something else, an old support, an important moving average, a zone of high activity in the order book. This confluence transforms a pencil line into a decision zone. Blindly buying every 0.618 is ritualistic, not methodical.

Let’s broaden the perspective. The golden number has fascinated since antiquity, from the proportions of the Parthenon to sunflower spirals, and markets have only added a chapter to this old story of humanity seeking order in chaos. On charts and elsewhere, order appears mainly where thousands of eyes search for it in the same place, just like with golden cross moving average intersections. The tool does not predict the crowd. It photographs it.
