What is Fibonacci retracement?
Fibonacci retracement levels are lines at set percents of a price swing. Traders watch them as places where a pullback might pause.
They are a map, not a promise. Price often ignores them, and Grade 7 shows when they tend to fail.
The formula in plain words
- Range = swing high minus swing low.
- In an uptrend, each level = swing high minus (range times the percent).
- In a downtrend, each level = swing low plus (range times the percent).
Uptrend level = High − (High − Low) × % Downtrend level = Low + (High − Low) × %
Worked example
An uptrend from 1.0900 up to 1.1100
- 1Range: 1.1100 minus 1.0900 = 0.0200.
- 238.2% level: 1.1100 minus (0.0200 × 0.382) = 1.10236.
- 350% level: 1.1100 minus (0.0200 × 0.5) = 1.1000.
- 461.8% level: 1.1100 minus (0.0200 × 0.618) = 1.09764.
The 38.2%, 50% and 61.8% pullback levels sit near 1.1024, 1.1000 and 1.0976.
Common mistakes
- Drawing from the wrong swing. Pick a clear, finished swing that others would also see.
- Treating a level as a place price must turn. It is only a place to watch.
- Stacking many tools until something lines up. Keep it to one or two reasons.
Questions people ask
Is 50% a Fibonacci number?
Not really. It comes from the idea of a half pullback, but traders include it with the Fibonacci levels.
What are Fibonacci extensions?
Levels past the swing, like 127.2% and 161.8%. Some traders use them to think about where a move could reach.
Do Fibonacci levels work?
They are popular, which is part of why people watch them. They do not predict price. Grade 7 covers when they help and when they do not.
