Traders use several indicators to determine when to enter or exit a trade. And one of the most popular among technical investors is a Fibonacci retracement. This indicator is based on some key percentages that Leonardo Fibonacci identified.

In Fibonacci trading, the sequence is not as crucial as the mathematical relationships expressed as ratios.

What Are Fibonacci Retracement Levels?

A Fibonacci indicator is a crucial indicator that investors use when drawing support lines. They also help set target prices, place stop-loss orders, and identify the resistance levels. Fibonacci levels are associated with a percentage.

It’s the percentage of how much of its previous move it has retraced. These retracement levels are 78.6%, 61.8%, 38.2%, and 23.6%. Even though it isn’t official, traders use 50% as a Fibonacci ratio.

The Fibonacci retracement strategy is useful since; you have to draw the line between two important price points. These price points are either low or high. It will then help create these levels between 2 points.

The Formula for Fibonacci Retracement Levels

Generally, the retracement levels don’t have a formula. Instead, when applied, you can pick two points on the chart. After picking the right points, you can draw the line at a percentage of that move.

For instance, if the price increases by $5 from $10, you can use the two levels to draw your retracement indicator.

So the 23.6% will be at $13.82, which is obtained by $15 – ($5 x 0.236). The position of the 50% retracement level is $12.50, which is determined by ($15 – ($5 x 0.5) = $13.82. With Fibonacci trading, you must create your strategy using these retracement levels.

How to Calculate Fibonacci Retracement Levels?

The Fibonacci levels are percentages of the selected price range. The origin of these numbers can be quite fascinating. They’re all based on the Golden Ratio. For instance, if you start with zero, you can create a sequence by adding the previous two numbers to get the next one.

Traders obtain these levels from a string of numbers. And once it gets going, if you divide a number by the next one, you’ll get 61.8%. When you divide it by the second number to its right, you’ll get 38.2% or 0.382. You can get all the ratios except for 50%.
