What are Fibonacci Levels?

Fibonacci retracement levels are horizontal lines that indicate where support and resistance are likely to occur. They are derived from the Fibonacci sequence, a series of numbers where each number is the sum of the two preceding ones.

Key Retracement Levels

23.6%
Shallow retracement, strong trend continuation
38.2%
Common pullback level in strong trends
50.0%
Psychological halfway point
61.8%
Golden ratio - strongest level
78.6%
Deep retracement, last defense

Retracement Formula

Uptrend: Level = High - (Range × Ratio)
Downtrend: Level = Low + (Range × Ratio)
Where Range = High - Low

How to Use Fibonacci Levels

1. Identify the Trend: Determine if the market is in an uptrend or downtrend.

2. Find Swing Points: Locate the most recent significant high and low.

3. Apply Levels: The calculator will show where price might find support (in uptrend) or resistance (in downtrend).

4. Look for Confluence: Fibonacci levels work best when combined with other technical analysis tools like moving averages, trend lines, or candlestick patterns.

You draw Fibonacci on every chart. But does it actually work for you?

Frequently Asked Questions

What are Fibonacci retracement levels?
Fibonacci retracement levels are horizontal lines indicating where support and resistance are likely to occur. They are based on Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%) and are calculated by measuring the distance between a significant high and low.
What is the golden ratio in trading?
The golden ratio (61.8% or 0.618) is considered the most important Fibonacci level. It's derived from dividing a Fibonacci number by its successor. Traders watch this level closely for potential reversals as it often acts as strong support or resistance.
What are Fibonacci extensions?
Fibonacci extensions are levels beyond 100% used to project potential profit targets. Common extension levels are 127.2%, 161.8%, 200%, and 261.8%. They help traders identify where price might move after breaking through retracement levels.
Which Fibonacci level is most reliable?
The 61.8% (golden ratio) and 50% levels are generally considered the strongest. Many traders focus on these for potential reversals. The 38.2% level is also significant in strong trends where shallow pullbacks are common.
Can Fibonacci levels be used for all markets?
Yes, Fibonacci levels work on any market - forex, stocks, crypto, commodities, and indices. They are applicable across all timeframes, from 1-minute charts to monthly charts. The key is to identify significant swing highs and lows.
