Fibonacci retracement is a tool traders use to identify potential support and resistance levels in the market. Typically, these are price levels where an asset might pause, bounce back, or reverse during its movement—either after going up or down.
The idea itself does not have its origins in trading, but comes from the Fibonacci sequence, a series of numbers that has been known for centuries. It follows the pattern: 0, 1, 1, 2, 3, 5, 8, 13, 21… and so on. Each number is the sum of the two before it. This sequence is replicated in nature, architecture, even the spirals of a seashell, and so traders thought, “why not use it in the financial markets too?”.
The beauty of it is that you don’t need to memorize the sequence. What’s more important are the ratios that come from it. These are percentages like 23.6%, 38.2%, 50%, 61.8%, and 78.6%, and they’re used to predict how far a price might retrace before continuing in its original direction.
The sequence was introduced to the world by a guy named Leonardo of Pisa, also known as Fibonacci, in the year 1202 through his book Liber Abaci. But Fibonacci didn’t device this retracement method for trading. That part came much later, as technical analysts and chartists started seeing patterns that these ratios seemed to line up with price action in the markets.
In the 20th century, and traders began using Fibonacci levels to help map out entry and exit points, stops, and price targets.
Let’s say you’re looking at a chart where a stock jumped from $10 to $15. That $5 jump is a “significant move.” Now, traders expect that the price might pull back a bit before continuing to rise—or even reverse direction. So, they apply Fibonacci retracement to measure potential pullback levels.
You will take that move from $10 (the swing low) to $15 (the swing high) and then apply those key Fibonacci percentages:
Now, in $13.09 and $11.91, you’ve got potential support levels where buyers might jump back in. Note that these levels are not foolproof. Sometimes they hold strong, sometimes they don’t, but they often give traders a useful heads-up.
Below, we look at what different Fibonacci levels mean:
How to Use Fibonacci Retracement in Trading
Below is a step-by-step guide on how to use Fibonacci retracement in trading.
Step 1: Identify the Trend
This is critical, as Fibonacci retracement works best when there’s a clear uptrend or downtrend in place. Without a trend, you’re basically applying math to chaos.
Step 2: Draw the Levels
Most trading platforms come with Fibonacci retracement tool. Here’s how you draw it:
Once you do that, horizontal lines will appear at 23.6%, 38.2%, 50%, 61.8%, and 78.6% marks. These will serve as your potential support and resistance levels.
Step 3: Watch Price Behavior Around the Levels
Here are useful hints on what you’ll be watching for:
The more a level aligns with previous price action, the stronger it becomes. Traders also look for other signs—like candles forming reversal patterns or volume spikes—to confirm their ideas.
On the chart above, the recent bounce toward 1.1649 (23.6%) suggests that price is attempting to resume the upward trend, but traders should watch this level closely for potential resistance. The 23.6% retracement level (1.1649) held briefly as a support zone during the initial pullback from 1.1830. However, the price eventually broke below it, indicating that bullish momentum was weakening. After the drop, the currency pair has recently bounced back up, and it’s now acting as resistance.
The EUR/USD pair found solid support at the 61.8% retracement (Golden Ratio) level after briefly dipping below it, before resuming its upward move. This behavior aligns with classical Fibonacci theory — many traders consider this a high-probability bounce zone.
While the Fibonacci retracement tool is helpful, but it’s not a magic formula. Therefore, it’s not wise to get overly reliant on it and ignore the broader market context.
Here are the key mistakes to avoid:
Fibonacci retracement is a good technical analysis tool, but when combined with other tools, it becomes great.
Some of the other indicators you can combine it with include:
Fibonacci retracement doesn’t tell you exactly what will happen, but it gives you a good idea of where price might take a breather or make a U-turn. Whether you’re trading crypto, stocks, forex, or even commodities, this is a useful tool to have in your technical analysis.
However, remember that it’s not the only tool, and neither is it sufficient on its own. To use it wisely, you need to combine it with other tools, and always stick to your trading plan. The markets may be unpredictable, but with the right approach, you can navigate them much more confidently.
