📈 Fibonacci Retracement Calculator
Calculate key Fibonacci support and resistance levels from any price swing.
How to Use This Calculator
Identify the Swing
Use recent price action to determine a meaningful swing high and swing low on your chart.
Enter Price Points
Input the swing high and swing low values. For downtrends, use the highest point first.
Generate Levels
Click calculate to obtain key Fibonacci retracement levels between the swing high and low.
Plan Your Trade
Combine Fibonacci levels with trend lines, volume, or oscillators for entry, exit, and stop-loss decisions.
Formula
Fibonacci Level = Swing High − (Swing High − Swing Low) × Fibonacci Percentage
Percentages come from the Fibonacci series (23.6%, 38.2%, 61.8%, etc.) and represent the probability of price retracing to those points.
Example: Swing High = 4325.50, Swing Low = 4180.25 → 61.8% Level ≈ 4220.25
Fibonacci retracement tools are most effective in trending markets. Use them to anticipate potential areas where price might reverse or consolidate before continuing the trend.
Full Description
Fibonacci retracement analysis is a staple of technical trading. By measuring the vertical distance of a price swing, traders project horizontal levels based on Fibonacci ratios derived from the golden ratio (≈ 1.618). These levels mark potential support and resistance zones where price may pause or reverse.
Professional traders combine Fibonacci levels with other technical indicators—such as moving averages, candlestick patterns, or market profile—to confirm trade setups. Retracement levels are also widely used to place stop-losses, scale into positions, or identify take-profit targets during counter-trend bounces.
Popular Strategies
- Trend Pullback Entries: Buy near 61.8% retracements in uptrends or sell in downtrends.
- Confluence Trading: Align Fibonacci levels with trendlines, pivot points, or moving averages.
- Multiple Time Frame Analysis: Validate intraday levels against higher timeframe swings.
- Risk Management: Place stops just beyond the next Fibonacci level to limit downside risk.
