Calculate Fibonacci retracement and extension levels from any swing high/low. Identify key support, resistance, and take-profit targets.
Level = High − (High − Low) × Fib Ratio
Example: High 1.1000, Low 1.0800: 61.8% retracement = 1.1000 − 200 × 0.618 = 1.0876
Fibonacci retracement levels (23.6%, 38.2%, 50%, 61.8%, 78.6%) are horizontal lines indicating where price may find support or resistance during a pullback.
The 61.8% level (golden ratio) is considered the most significant. The 38.2% and 50% levels are also widely watched by traders.
Fibonacci extensions (127.2%, 161.8%, 261.8%) project potential take-profit targets beyond the original swing. Traders use them to set profit targets when price breaks past the swing high or low.
