What is the Fibonacci sequence?
The Fibonacci retracement strategy involves the use of the Fibonacci sequence. So, let us first of all learn about the Fibonacci sequence.
The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones. The sequence usually is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so on.
The sum is in the following order:
In mathematical terms, the Fibonacci sequence can be defined recursively by the formula:
X(n) = X(n-1) + X(n-2)
Where:
- X(n) is the nth number in the sequence
- X(n-1) is the (n-1)th number in the sequence
- X(n-2) is the (n-2)th number in the sequence
In finance and trading, the Fibonacci sequence is widely used in technical analysis to identify potential support and resistance levels and is an essential part of the Fibonacci retracement strategy.
Moreover, there are some interesting properties of the Fibonacci sequence.
- Divide any number in the sequence by the previous number; the ratio is always approximately 1.618.
Xn/Xn-1 = 1.618
55/34 = 1.618
89/55 = 1.618
144/89 = 1.618
1.618 is known as the golden ratio. I suggest searching for the golden ratio examples on the Google images and you will be pleasantly astonished by the relevance of the ratio in nature.
2. Similarly, divide any number in the sequence by the next number; the ratio is always approximately 0.618.
Xn/Xn+1 = 0.618
34/55 = 0.618
55/89 = 0.618
89/144 = 0.618
3. 0.618 expressed in percentage is 61.8%. The square root of 0.618 is 0.786 (78.6%).
Similar consistency is found when any number in the sequence is divided by a number two places right to it.
Xn/Xn+2 = 0.382
13/34 = 0.382
21/55 = 0.382
34/89 = 0.382
0.382 expressed in percentage is 38.2%
4. Also, there is consistency when any number in the sequence is divided by a number three places right to it.
Xn/Xn+3 = 0.236
21/89 = 0.236
34/144 = 0.236
55/233 = 0.236
0.236 expressed in percentage terms is 23.6%.
5. The ratios 23.6%, 38.2%, 61.8%, and 78.6% are known as the Fibonacci ratios.
Now we can move to learning about Fibonacci retracement strategy.
What is the Fibonacci retracement strategy?
The Fibonacci retracement strategy is a popular technical analysis tool to identify potential reversal levels in financial markets and is used by traders. Based on the Fibonacci sequence, this strategy involves plotting key retracement levels. The typical or default levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%, against a price movement.
These levels are derived from ratios found in the Fibonacci sequence, believed to represent areas of support or resistance.
Fibonacci retracement levels help traders to identify the entry and exit points for trades. Hence, the determination of the stop-loss and take-profit levels is done. When the price of an asset retraces to one of these Fibonacci levels, it may indicate a potential reversal in the prevailing trend.
The Fibonacci ratios, 23.6%, 38.2%, and 61.8%, can be applied for time series analysis to find support levels. Whenever the price moves substantially upwards or downwards, it tends to retrace back before it continues moving in the original direction.
For example, if the stock price has moved from $200 to $250, it is likely to retrace to $230 before it continues to move upward. The retracement level of $230 is forecasted using the Fibonacci ratios.
We can arrive at $230 by using simple maths.
- Total up move = $250 - $200 = $50 38.2% of up move = 38.2% * 50 = $19.1
- Retracement forecast = $250 - $19.1 = $230.9
Any price below $230 provides a good opportunity for the traders to enter into new positions in the direction of the trend. Likewise, we can calculate for 23.6%, 61.8% and the other Fibonacci ratios.
The Fibonacci retracement strategy is commonly applied alongside other technical indicators and analysis techniques to confirm signals and enhance trading decisions. Additionally, it can be used across various financial instruments and timeframes, making it a versatile tool for traders across different markets.
Let us now find out how to use Fibonacci retracement in trading.
How to use Fibonacci retracement in trading?
The retracement levels can be used to buy a particular stock but you have not been able to because of a sharp run-up in the stock price.
In such a situation, it is recommended to wait for the price to correct to Fibonacci retracement levels such as 23.6%, 38.2%, and 61.8% and then buy the stock. The ratios 38.2% and 61.8% are the most important support levels.
This Fibonacci retracement trading strategy is more effective over a longer time interval and like any indicator, using the strategy with other technical indicators such as RSI, MACD, and candlestick patterns can improve the probability of success.
Now, we will head to calculating Fibonacci retracement levels using Python.
Calculating Fibonacci retracement levels using Python
As we now know, retracements are the price movements that go against the original trend. To forecast the Fibonacci retracement level we should first identify the total up move or total down move. To mark the move, we need to pick the most recent high and low on the chart.
Let’s take an example of Exxon Mobil to understand the Fibonacci retracement construction.
Output:
Output:
Minimum Price: 31.56999969482422 Maximum Price: 121.37000274658203
Output:
Level Price 0 121.37000274658203 0.236 100.17720202636718 0.382 87.06640158081055 0.618 65.8736008605957 1 31.56999969482422
It is visible that the maximum price is 121.37 where the level is 0 since there is no retracement at the maximum price.
The first retracement level is at 23.6% is $100.17, the second retracement level is at 38.2% is $87.06, and the next retracement level is at 61.8% is $65.87.
Best practices for optimising Fibonacci trading strategy in Python
When you implement Python for the Fibonacci trading strategy, there are chances that optimisation will be required to improve the strategy performance.
Consider the following tips and best practices for the same:
- Define clear trading rules: Establish clear rules for identifying Fibonacci retracement levels and trade setups. This helps to remove subjectivity and emotion from the decision-making process.
- Backtest the strategy: Use historical market data to backtest the Fibonacci strategy across various market conditions. This helps validate the effectiveness of the strategy and identify its strengths and weaknesses.
- Optimise parameters: Fine-tune the parameters of the Fibonacci strategy, such as the anchor points for drawing retracement levels or the threshold for confirming trade signals. Optimisation can be done using techniques like grid search.
- Incorporate risk management: Implement robust risk management techniques to protect capital and minimise losses. This may include setting stop-loss orders, position sizing based on risk tolerance, and diversifying across multiple assets or instruments.
- Combine with other indicators: Enhance the Fibonacci strategy by integrating it with other technical indicators or chart patterns. This can help confirm trade signals and increase the probability of successful trades.
- Continuously monitor and adapt: Regularly monitor the performance of the Fibonacci strategy and make adjustments as needed based on evolving market conditions. This may involve refining the strategy parameters, adding new filters, or incorporating feedback from live trading experiences.
By following these tips and best practices, traders can optimise their Fibonacci trading strategy in Python and improve their overall trading performance.

|
False Signals: Fibonacci retracement levels may sometimes generate false signals, resulting in poor trade execution and losses. |
Combine with Other Indicators: Use Fibonacci levels in conjunction with other technical indicators, such as moving averages, trendlines, or candlestick patterns, to confirm trade setups. This can help filter out false signals and improve the reliability of the strategy. |
|
Emotional Bias: Traders may become emotionally attached to Fibonacci levels, leading to biased decision-making and reluctance to adapt to changing market conditions. |
Stay Disciplined: Stick to predefined trading rules and objectives, regardless of emotional impulses or attachment to Fibonacci levels. Regularly review and adjust the strategy based on objective performance metrics and market feedback. |
|
Market Noise: In choppy or volatile market conditions, Fibonacci levels may not accurately capture price movements, resulting in increased noise and false signals. |
Adjust Parameters: Consider adjusting the sensitivity of Fibonacci levels by modifying the anchor points or using alternative Fibonacci tools, such as Fibonacci extensions or clusters, to better align with prevailing market dynamics. Additionally, apply filters to smooth out noise and focus on high-probability trade setups. |
