What is Fibonacci Retracement?
Fibonacci retracement is one of the most widely used technical analysis tools in trading. It uses horizontal lines to indicate potential support and resistance levels based on the Fibonacci sequence, a mathematical pattern found throughout nature and financial markets. The key Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, and 78.6%) are derived from relationships within this sequence and help traders identify where price may pause or reverse during a trend.
Our free Fibonacci retracement visualizer allows you to calculate these critical levels instantly. Simply enter your swing high and swing low prices, or upload historical price data in CSV or JSON format. The tool automatically calculates all retracement levels and optional extension levels, displaying them on an interactive chart for easy analysis.

Understanding Fibonacci Levels
| Level | Significance | Trading Application |
|---|---|---|
| 0% / 100% | Swing high/low boundaries | Defines the measured move |
| 23.6% | Shallow retracement | Strong trends often bounce here |
| 38.2% | Moderate retracement | Common pullback level in trends |
| 50% | Psychological midpoint | Not a Fibonacci ratio but widely watched |
| 61.8% | Golden ratio (commonly watched) | Reference zone that still needs confirmation |
| 78.6% | Deep retracement | Last defense before trend reversal |
| 127.2% - 261.8% | Extension levels | Profit targets beyond the swing |

Fibonacci trading methods
A Fibonacci level does not confirm a trade by itself. Traders often compare it with market structure, moving averages, or candle behavior before writing an entry rule.
1. Fibonacci and trend lines
Draw trend lines connecting swing highs or lows. When a Fibonacci level coincides with a trend line, it creates a shared reference area. Price can still pass through it.
2. Fibonacci and moving averages
Compare Fibonacci levels with a 50 EMA or 200 SMA. An overlap gives you another price reference, not proof that support or resistance will hold.
3. Fibonacci and candlestick patterns
Wait for reversal candlestick patterns (doji, engulfing, hammer) at Fibonacci levels before evaluating an entry. The candle adds evidence but does not confirm a reversal.
4. Multiple-timeframe Fibonacci
Draw Fibonacci levels on multiple time frames. When levels from different timeframes cluster together, mark the area for closer review and define a failure condition.
