Fibonacci is a highly regarded analytical tool known for its accuracy and reliability, based on the golden ratio. Many traders are likely interested in learning Fibonacci or applying it in their trading chart.
However, one of Fibonacci’s characteristics is that it can be somewhat difficult to understand. When trying to use it, many traders often struggle with how to insert it and how to analyze it.
In this article on FX Chart Analysis, a wide range of analytical methods is introduced for traders from beginners to advanced levels.
Providing a thorough explanation of two core Fibonacci methods: the Fibonacci Retracement as the basic technique, and the Fibonacci Expansion as an extension tool. These two methods, often referred to as the “Basic Fibonacci techniques”, can significantly enhance your trading strategy. Addionally, four other types of Fibonacci tools are explained.
This chart analysis will be a valuable resource for your trading.

FX Technical Analysis: Fibonacci
There are several types of Fibonacci techniques in chart technical analysis. Many traders may be unsure about which to start with or how to use them.
The main Fibonacci tools include:
- Fibonacci Retracement
- Fibonacci Expansion
- Fibonacci Channel
- Fibonacci Fan
- Fibonacci Arc
- Fibonacci Time Zone
The basic Fibonacci approach refers specifically to the use of Fibonacci Retracement and Fibonacci Expansion together.
All Fibonacci methods are based on Fibonacci ratios, derived from the golden ratio.
What is the Golden Ratio?
| The golden ratio represents the most harmoniously balanced proportion. In Western culture, it has been used in architecture and art since ancient times, considered the proportion most aesthetically pleasing to humans. |
Mathematically, the golden ratio can be expressed as:
ϕ=21+5≈1.6180339887…
In practice, it is commonly rounded to 1:1.618.
The golden ratio has been applied to many iconic works, from the Venus de Milo and the Egyptian pyramids, to Leonardo da Vinci’s paintings, Michelangelo’s sculptures, modern Apple logos, and even in the dimensions of flags and business cards.
What is the Fibonacci Ratio?
| Separately, the Fibonacci ratio was discovered in a mathematical context and matches the golden ratio of 1:1.618. |
This ratio was introduced by the Italian mathematician Leonardo Fibonacci in the 13th century. Because his discoveries coincided perfectly with the golden ratio, Fibonacci’s work became widely celebrated and is still highly regarded today.
Fibonacci Sequence
The Fibonacci ratio is derived from the Fibonacci sequence, a mathematical series where each number is the sum of the two preceding numbers:
1+1=2、1+2=3、2+3=5、3+5=8・・・・
1,1,2,3,5,8,13,21,34,55,89,…
Continuing this pattern indefinitely, the ratio of consecutive numbers approaches 1.618, converging on the golden ratio.
Fibonacci Sequence and Geometry
By arranging Fibonacci numbers into squares (e.g., 1, 1, 2, 3, 5…), a unique pattern emerges: rectangles are formed in a consistent proportion, which always approximates 1:1.618.
This demonstrates that the golden ratio, used since antiquity, was mathematically validated through Fibonacci’s discoveries, confirming it as a universal and unchanging law.
Examples of the Golden Ratio and Fibonacci Ratio
| When drawing quarter circles inside the squares of a Fibonacci sequence, a spiral is formed. This Fibonacci spiral appears frequently in nature: |
Fibonacci Ratio and Seashells
- Seashells and snail shells
- Sunflower seeds, aloe leaves, and other plants
- Galaxies such as the Milky Way, and even the spiral patterns of typhoon clouds
- Classic artworks by Hokusai or Leonardo da Vinci
- Eggs, and even population and statistical maps
Sunflower Seeds
Milky Way, Typhoon Clouds
Hokusai, Leonardo da Vinci, Egg
Vitruvian Man, Population Map
The Fibonacci sequence and ratio have thus become absolute principles, confidently applied in data analysis and market analysis.
The Five Fibonacci Techniques
Fibonacci tools can be broadly classified into five main types:
- Fibonacci Retracement
- Fibonacci Expansion
- Fibonacci Channel
- Fibonacci Fan
- Fibonacci Arc
- Fibonacci Time Zone
Let’s take a brief look at each of these techniques.
Fibonacci Retracement
The Fibonacci Retracement is a drawing tool that inserts six horizontal lines on a chart based on Fibonacci ratios. Among the various Fibonacci methods, this is the most standard and widely used technique by traders.
From the starting price, horizontal lines are drawn at ratios ranging from 23.6% to 100%. Each line can be used as a support or resistance line, or as a target price for trading decisions. Its ease of use, similar to drawing support and resistance lines, makes it highly popular.
【Check Point】
It is most efficient in certain patterns of price movement, especially during steep uptrends and downtrends. Generally line 0.0 would be adjust with start point of trend, then first reversal point 100.0 (61.8).
If the price breaks through one line, there is a possibility that it will move to the next line above (or below).
- 61.8 or 100.0 line is critical point.
- If price break 61.8 or 100.0, trend goes further line to 168.0
- 168.0 could be strong resistance or support line, to judge the trend
Fibonacci Expansion
The Fibonacci Extension extends the concept of Fibonacci Retracement to capture longer-term trends and movements.
While standard Fibonacci tools go up to 100% or 168.1%, the Extension can be extra ratios beyond the range of retracement, additional 61.8%, 100.0％, and 161.8%, making it useful to keep analyzing how far trend goes.
【Check Point】
At the upward trends, it could be the sign of higest level. Likewise at the downward trends it helps to tell where is the lowest level.
- If the price break 61.8 and 100.0, high possibility of going 161.8.
- If the price break under 61.8, red line could be support level.
- Expansion is convininent fo also between two line of Fibonacci.
| Fibonacci Expansion is also called Fibonacci Extension, it can be used as optional setting in Fibonacci Retracement. |
Fibonacci Channel
The Fibonacci Channel is a very convenient tools to figure out each trend movement inside a long-term trend.
Most of the time, trend goes up and down repeatedly inside one particular trend. The Fibonacci Channel help to set highest, lowest and turning point with 50% to 261.8%.
【Check Point】
Set a starting point at the lowest or highest point of a long-term trend. Then adjust the second point to any reversal level, ensuring that all Fibonacci lines fit the price movement.
- Each lines can be resistance and support levels.
- Help to identify the trend between each lines.
- Usually each small trend will move inside Channels.
Fibonacci Fan
The Fibonacci Fan is a drawing tool with diagonal trendlines. Unlike Fibonacci Retracement, it allows traders to visualize trends that cannot be captured by horizontal lines.
From the starting price, diagonal lines are drawn at Fibonacci ratios from 38.2.%, 50.0%, and 61.8%, which can help identify trendlines, channels, and potential upper and lower boundaries.
【Check Point】
It is used for well-defined trendline, usually price will move inside Fibonacci Fan. Three blue lines and Red line can be resistance and support line.
If the price breaks topline, one line, there is a possibility that it will move to the next line above (or below).
- If price breaks 38.2, there is possibility to go toward redline.
- If price break 61.8, more likely to occure trend reversal.
- Unless price keep within 61.8, trend will be continued
Fibonacci Arc
The Fibonacci Arc draws circular 3 lines, it could be useful unstable trend or range price pattern, to analyze each movement relationships with distance point.
From the starting price, three lines show 38.2%, 50.0%, and to 61.8%, allowing traders to gauge timing for trend continuation, reversal, or shifts in momentum.
【Check Point】
The mixed trends are likely to move inside or near three lines. Likewise other Fibonacci, three lines could be resistance and support levels.
If the price breaks topline, one line, there is a possibility that it will move to the next line above (or below).
- If price breaks 38.2, another price range will be occured.
- If price break 61.8, further upward or downward is expected.
- Unless price keep within three lines, trend will be stay in Fibonacci.
Fibonacci Time Zone
The Fibonacci Time Zone place vertical lines on a chart at Fibonacci sequence intervals (1, 2, 3, 5, 8, 13, 21…), used to forecast potential trend reversals or market direction changes.
【Check Point】
Trader can draw a line at beginning of trend to a second significant price point to set the time zone.
- Each line can be the sign to identify potential reversal point
- Each interval can be the sign for a trend length.
- These line indicate not a price, but a key turning point.
All Fibonacci Tools Are Based on Fibonacci Ratios
Regardless of the starting point, all Fibonacci tools are grounded in the golden ratio and Fibonacci proportion.
Lines are typically drawn at:
- 0.0%
- 23.6%
- 38.2%
- 50.0%
- 61.8%
- 100.0%
- 161.8%
Basic Knowledge of Fibonacci Retracement and Extension
Now that the main Fibonacci tools have been covered, let’s focus on the most practical combination: Fibonacci Retracement and Fibonacci Extension.
This method combines retracement levels 100% with extension levels above 100% to 216%.
Many trading platforms allow these levels to be displayed directly from the standard Fibonacci Retracement settings. And if the provided tool does not have an optional setting over 100%, Fibonacci Expansion can be used.
Fibonacci Ratios Displayed
The ratios available in Fibonacci Extension vary by platform or type of Fibonacci, but the most common levels are:
- 61.8%
- 100.0%
- 161.8%
- 261.8%
Some platforms can display 400% and even higher levels.
For Fibonacci Retracement, the main levels are:
- 0.0%
- 23.6%
- 38.2%
- 50.0%
- 61.8%
- 100.0%
This makes Extensions especially useful when analyzing price movement beyond the normal retracement range.
Using Fibonacci Extension
While Retracement usually covers up to 100%, Extension continues the same measurement beyond that point.
For example, after 100%, the next major targets often become,
- 161.8%
- 261.8%
- or more
This allows traders to continue tracking the same trend without changing the original starting point.
It is particularly effective when analyzing continuous uptrends and downtrends (uptrends) as one unified move.
Easy Way to Use Extension
If your trading platform does not support Extension, recommend to use MT5 demo version as a free chart analysis tool. If Fibonacci ratios are to be displayed over a wider range, that can easily be done from the parameter settings screen in MT5.
MT5 includes extension functionality within Fibonacci Retracement settings, making it easy to use for both beginners and advanced traders.
Trading with Fibonacci Retracement and Extension
Here is a practical way to use Fibonacci on a MT5 chart.
From the menu bar of MT5: Insert → Objects → Fibonacci → Fibonacci Retracement
2) Insert Fibonacci from the High or Low
Set the 0.0% point at the major swing high or swing low.
Then align the 61.8% level with the first major pullback or rebound point.
①Adjust the line width
② Move the entire object
③ Adjust the length
The lines are adjusted to fit the price movement — for example, by moving them or widening them according to the chart’s price momentum.
3) Use Each Level as Support and Resistance
Once the Fibonacci levels are set, each line can be used as a support or resistance level. Such as entry point and exit point.
A bounce from a support line may signal a continuation trade, while rejection at resistance may suggest a reversal.
4) Decide Entries and Exits by Line Breaks
A simple approach is to watch whether price:
- bounces from a level
- breaks above a level
- falls below a level
Typical examples:
- Bounce from support → Buy
- Break above resistance → Hold or Buy
- Fall from support → Sell
If momentum remains strong, price may continue toward 161.8% and 261.8%.
The 61.8% level remains the most important checkpoint for possible reversal.
Summary
Among the wide variety of indicators and analytical methods available, Fibonacci stands out as a more convincing tool because it is based on the golden ratio. Its accuracy is remarkably high, and once mastered, it can become a powerful weapon.
The key to using extensions effectively lies in where the starting point is set and how wide the range is configured. An important technique is to slightly adjust the placement based on lines, price momentum, and trends. The best matches will lead to more precise analysis.
Let’s insert it into your chart — try the power of the Fibonacci Extension for yourself.
