This calculator will help calculate the Fibonacci retracements and extensions based on price points. This is a popular tool among traders used to identify support and resistance levels, and place stop-loss orders or target prices. Simply put, Fibonacci is primarily used to measure how far a market has retracted its primary move. While Fib Retracement refers to a specified price range, Fib Projection values are applied outside the price range. A Fibonacci retracement is created by taking 2 extreme price points and dividing by the key Fibonacci ratios of 23.6%, 38.2%, 50%, 61.8%, and 100%.
