What Is Fibonacci Retracement? How to Draw and Use It

Fibonacci retracement is a technical-analysis tool that uses a set of horizontal lines to mark where the price of an asset might pause or reverse during a pullback. The lines are drawn at percentages derived from the Fibonacci number sequence, and traders use them to anticipate potential support and resistance levels after a strong move.

Where the levels come from

The tool is named after the Fibonacci sequence, in which each number is the sum of the two before it (1, 1, 2, 3, 5, 8, 13, and so on). Ratios between numbers in this sequence produce the percentages traders plot on a chart. The most common Fibonacci retracement levels are:

• 23.6%
• 38.2%
• 50% (not a true Fibonacci ratio, but widely included by convention)
• 61.8% (often called the "golden ratio")
• 78.6%

The idea is that after a price makes a strong move up or down, it often "retraces" — pulls back part of the way — before continuing. These levels mark common places where such pullbacks may stall.

How to draw and use it

To apply the tool, a trader picks a clear swing — a low to a high in an uptrend, or a high to a low in a downtrend — and the charting software draws the retracement lines between those two points. In an uptrend, the levels sit below the recent high and are watched as potential support; in a downtrend, they sit above the recent low and are watched as potential resistance.

The 38.2% and 61.8% levels attract particular attention. A pullback that holds near one of them and then resumes the original trend is a classic setup traders discuss. Fibonacci levels are frequently combined with other tools — the wave structure in Elliott Wave theory, the trend logic of Dow Theory, or the support zones of the Ichimoku Cloud — because agreement between several methods is generally seen as more meaningful than one alone.

An important caveat

Fibonacci retracement is a guide, not a rule. Price does not have to respect these levels, and part of their reputation comes from the fact that so many traders watch the same numbers, which can make them partly self-fulfilling. They work best as areas of interest to watch, not precise lines that dictate what price must do.

A worked example

Suppose an asset rallies from 100 to 200, then begins to pull back.

• A trader draws the retracement from 100 to 200.
• The 38.2% level sits around 162, the 50% level at 150, and the 61.8% level around 138.
• If the pullback slows and stabilises near the 61.8% level (~138) and the uptrend resumes, that level is judged to have acted as support.

Because these are probabilistic zones rather than guarantees, acting on them carries risk, and leverage magnifies it. Anyone using Fibonacci levels in futures or perpetual contracts should predefine risk in case price slices straight through a level. This is educational information, not trading advice.

Summary

Fibonacci retracement plots levels derived from the Fibonacci sequence to highlight where a pullback might find support or resistance, with 38.2%, 50%, and 61.8% the most watched. It is a probabilistic guide, strongest when it agrees with other tools, and never a guarantee of how price will behave.
