Fibonacci Calculator

The Fibonacci Calculator determines commonly used retracement and extension levels for upward and downward price movements.

Enter the high and low prices of a movement to calculate standard Fibonacci levels. You can also specify an additional custom price point for extension calculations. The resulting levels can be used as reference points when analyzing possible areas of price reaction, support, or resistance.

Fibonacci levels are analytical reference levels and do not predict future price movements.
