Fibonacci Retracement

Calculate Fibonacci retracement and extension levels for any price swing.

Swing High ($)

Swing Low ($)

How it works: Fibonacci retracement levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) are based on the Fibonacci sequence. Traders use them to identify potential support and resistance levels during pullbacks. The 61.8% "golden ratio" is the most respected level. Extensions (127.2%, 161.8%) project where price might go after breaking the swing high/low.
