Fibonacci Retracement Calculator

Calculate Your Fibonacci Levels

Determine key levels of support and resistance for your trading strategy using the Fibonacci retracement calculator.

Results

Data Source and Methodology

All calculations are based on the standard Fibonacci retracement formulas. For more information, visit Investing.com. All calculations are strictly based on the formulas and data provided by this source.

The Formula Explained

The Fibonacci retracement levels are calculated using the formula:

Retracement Level = High - ((High - Low) × Fibonacci Level)

Glossary of Terms

  • High Price: The highest price point in the chosen range.
  • Low Price: The lowest price point in the chosen range.
  • Fibonacci Level: Common levels include 23.6%, 38.2%, 50%, 61.8%, and 78.6%.

How It Works: A Step-by-Step Example

Suppose the high price of a stock is $150 and the low price is $100. To find the 38.2% retracement level:

Retracement Level = 150 - ((150 - 100) × 0.382) = 130.9
