Identifies where a pullback may pause or reverse within an existing trend. Only needs Point A (low) and Point B (high).
Identifies take-profit targets beyond the original swing after a pullback ends. Requires three points: A, B, and C (pullback end).
What Are Fibonacci Retracement Levels? â The Most Widely Used Support & Resistance Tool
Fibonacci retracement levels are horizontal price zones derived mathematically from the Fibonacci sequence â a series where each number is the sum of the two preceding it (1, 1, 2, 3, 5, 8, 13, 21âĻ). The ratios between these numbers produce a set of universal constants: 23.6%, 38.2%, 50%, 61.8%, and 78.6% â which appear repeatedly in nature, art, and financial market price structure.
In trading, these levels mark zones where a pullback within a trend is statistically likely to find support (in an uptrend) or resistance (in a downtrend) before the primary move continues. They are used across forex, crypto, stocks, indices, and commodities by retail and institutional traders alike â their effectiveness reinforced by the self-fulfilling nature of widely-watched levels.

Fibonacci Levels Quick Reference â Retracement & Extension
The table below covers all Fibonacci levels generated by this calculator â from shallow retracements to deep extensions â with significance ratings and practical use cases for each level.
| Level | Type | Strength | Trading Application |
|---|---|---|---|
| 23.6% | Retracement | Moderate | Shallow pullback entry in strong trends â only valid with momentum confirmation |
| 38.2% | Retracement | Strong | First major entry zone â suits traders targeting early re-entries after pullbacks |
| 50.0% | Retracement | Strong | Psychological midpoint â not a true Fibonacci ratio but widely respected by institutions |
| 61.8% | Retracement | Very Strong | Golden Ratio â the most powerful retracement level across all markets and timeframes |
| 78.6% | Retracement | Strong | Deep retracement entry â trend structure still valid but needs confluence confirmation |
| 100.0% | Both | Critical | Full retracement of the prior move â breakdown here signals potential trend reversal |
| 138.2% | Extension | Moderate | First extension target beyond the swing â used in moderate-strength trend environments |
| 161.8% | Extension | High | Primary Fibonacci extension target â the most widely used profit target in trending markets |
| 261.8% | Extension | Moderate | Extended target in exceptionally strong trend environments with high momentum |
How to Use Fibonacci Retracement Levels in Trading
Drawing Fibonacci retracement levels is only the first step â the real skill is combining them with other confluence factors to filter high-probability trades from noise. The following workflow is used by professional traders across forex and crypto.
Find a clearly defined swing low and swing high (bullish) or swing high and swing low (bearish) on a higher timeframe (H4 or Daily). The cleaner and more obvious the move, the more reliable the Fibonacci levels.
Input the swing low as Point A and swing high as Point B for a bullish move. Select Bearish and reverse for a downtrend. The calculator generates all key levels instantly.
The most reliable trade setups occur when a Fibonacci level (especially 38.2%, 50%, or 61.8%) aligns with a previous support/resistance zone, a moving average, a trendline, or a candlestick pattern. Multiple confluences = higher probability.
Don't enter at the Fibonacci level alone. Wait for a reversal candle (pin bar, engulfing, hammer) or a break of a lower-timeframe structure before committing. This reduces false entries significantly.
Place your stop loss just beyond the next Fibonacci level (e.g. entry at 61.8%, stop below 78.6%). Set take-profit targets at the 0% level (swing high) or use the Projection mode to calculate extension targets at 138.2% and 161.8%.

Frequently Asked Questions
What are the most important Fibonacci retracement levels?
The three most widely respected Fibonacci retracement levels are 38.2%, 50%, and 61.8%. The 61.8% level â the Golden Ratio â is considered the most significant because price most frequently reverses or finds strong support/resistance there before continuing in the trend direction. The 50% level is not a true Fibonacci ratio but is included for its psychological significance and is closely watched by institutional traders.
How do I draw Fibonacci retracement levels correctly?
For a bullish move: identify the swing low (Point A) and swing high (Point B), then enter those values into this calculator â levels draw downward from B toward A, representing potential support zones during a pullback. For a bearish move: identify the swing high as Point A and swing low as Point B â the levels project upward from B as potential resistance zones. The key is identifying clean, clearly defined swing points on a higher timeframe (H4 or Daily) for the most reliable results.
What is the difference between Fibonacci retracement and Fibonacci extension/projection?
Fibonacci retracement levels (0%â100%) identify where a pullback within a trend may pause or reverse. Fibonacci extensions or projections (100%â261.8%) identify where the next impulse wave may reach after the pullback completes â used as take-profit targets. This calculator supports both modes: switch to Projection and enter Point C (where the pullback ended) to generate extension targets.
Do Fibonacci levels work in forex and crypto trading?
Yes â Fibonacci levels are used extensively across forex, crypto, stocks, and commodities. Their effectiveness is partly self-fulfilling: because millions of traders â including institutional algorithms â watch the same levels, price tends to react at them. The 38.2%, 50%, and 61.8% retracement levels in particular consistently attract significant order flow. They work best when combined with other confluence factors such as prior support/resistance, moving averages, or candlestick reversal patterns.
Which timeframe is best for Fibonacci retracement analysis?
Higher timeframes produce more reliable Fibonacci levels because the swing points are cleaner and more significant. The Daily and H4 timeframes are most commonly used for identifying the primary swing points. Once levels are drawn, many traders drop to H1 or M15 for entry timing â using the higher-timeframe Fibonacci zones as the decision area and the lower timeframe for confirmation.
Can I embed this Fibonacci calculator on my website?
