Fibonacci Retracement Calculator
Quickly compute fibonacci retracement with accurate formulas. See amortization schedules, growth projections, and side-by-side comparisons.
Formula
Retracement Level = High − (Range × Fib Ratio) [uptrend] | Low + (Range × Fib Ratio) [downtrend]
Fibonacci retracement levels are calculated by taking the difference between the swing high and swing low (the range) and multiplying by each Fibonacci ratio. For an uptrend, levels are subtracted from the high to show support below. For a downtrend, levels are added to the low to show resistance above. The OTE zone spans the 61.8% to 78.6% retracement levels.
Worked Examples
Example 1: EUR/USD Bullish Retracement
Problem: Swing Low: 1.0800, Swing High: 1.1000. Calculate retracement levels.
Solution: Range = 1.1000 - 1.0800 = 0.0200\n23.6% = 1.1000 - (0.0200 × 0.236) = 1.0953\n38.2% = 1.1000 - (0.0200 × 0.382) = 1.0924\n50% = 1.0900\n61.8% = 1.0876\n78.6% = 1.0843\nOTE Zone: 1.0876–1.0843
Result: OTE Zone: 1.0843–1.0876 | Golden Ratio: 1.0876
Example 2: GBP/USD Bearish Retracement
Problem: Swing High: 1.2700, Swing Low: 1.2500. Calculate levels for a bearish retracement.
Solution: Range = 0.0200\n38.2% = 1.2500 + (0.0200 × 0.382) = 1.2576\n50% = 1.2600\n61.8% = 1.2624\n78.6% = 1.2657\nLook for sell setups at 61.8-78.6% retracement
Result: OTE Zone: 1.2624–1.2657 | 50% midpoint: 1.2600
Frequently Asked Questions
What is Fibonacci retracement in trading?
Fibonacci retracement is a technical analysis tool that uses horizontal lines to indicate areas of support or resistance at key Fibonacci levels before price continues in the original direction. The levels are derived from the Fibonacci sequence and represent ratios: 23.6%, 38.2%, 50%, 61.8%, and 78.6%. Traders draw these levels between a significant swing high and swing low. The theory is that after a significant price move, price will often retrace to one of these levels before continuing. The 61.8% level (known as the golden ratio) is considered the most significant.
How do I draw Fibonacci retracement levels correctly?
For an uptrend: draw from the swing low to the swing high. The retracement levels will appear below the high, indicating potential support levels where price may bounce. For a downtrend: draw from the swing high to the swing low. The levels will appear above the low, indicating potential resistance levels. Always use significant swing points, not minor fluctuations. Higher timeframe Fibonacci levels are more significant than lower timeframe levels. The swing points should be clear and obvious — they should be the highest/lowest points of a defined move.
Which Fibonacci level is most important for trading?
The 61.8% level (golden ratio) is widely considered the most important Fibonacci level. When price retraces to this level, it indicates a strong pullback while still maintaining the overall trend structure. The 38.2% level represents a shallow retracement in strong trends. The 50% level, while not technically a Fibonacci ratio, is included because markets frequently retrace half of a move. In ICT methodology, the 61.8-78.6% zone (OTE) is considered optimal. Many traders look for confluence — where multiple Fibonacci levels from different swings align at the same price.
What are Fibonacci extensions and how are they different from retracements?
Fibonacci retracements identify potential reversal levels within a price move (between 0% and 100%), while Fibonacci extensions project levels beyond the original move (above 100%). Common extensions are 127.2%, 161.8%, 200%, and 261.8%. Extensions are used to set profit targets — for example, after entering at the 61.8% retracement, a trader might target the 127.2% or 161.8% extension. Extensions answer 'how far might price go beyond the original move?' while retracements answer 'how far might price pull back before continuing?'
