Calculate retracement and extension levels for any price swing. Know exactly where price is likely to pause, reverse, or continue.
A Fibonacci calculator applies key ratios 23.6%, 38.2%, 50%, 61.8%, and 78.6% to any price swing to identify where markets commonly retrace before continuing their trend or reverse entirely. These levels are used by traders across Forex, stocks, crypto, and indices to plan entries, exits, and stop-losses with precision.
A Fibonacci retracement is a technical analysis tool that uses horizontal lines to indicate potential support or resistance levels based on key Fibonacci ratios — 23.6%, 38.2%, 50%, 61.8%, and 78.6%. These levels are drawn between a significant high and low to predict where price might pull back before continuing its trend.
The most widely watched levels are 38.2%, 50%, and 61.8%. The 61.8% level known as the "golden ratio" is considered the most significant and often acts as the strongest area of support or resistance. The 50% level, while not a true Fibonacci number, is also heavily traded.
Identify a clear swing high and swing low. Then look for price to pull back into a key Fibonacci level (typically 38.2%–61.8%) before resuming the trend. Combine Fibonacci levels with other signals, like candlestick patterns, volume, or trend indicators — for higher-probability setups.
Retracement levels help you find potential reversal zones within an existing move, ideal for planning entries. Extension levels project where price may go beyond the original high or low useful for setting profit targets.
