What are Fibonacci retracement levels?
Fibonacci retracements are horizontal price levels that indicate potential support or resistance based on the Fibonacci sequence ratios. They are derived from the mathematical relationships within the sequence (0, 1, 1, 2, 3, 5, 8, 13...) and appear throughout nature, architecture, and — traders argue — financial markets.
The key levels
- 23.6% — Shallow retracement. Strong trending moves often only pull back this far.
- 38.2% — First significant level. Common entry zone in strong trends.
- 50% — Not a true Fibonacci ratio, but widely respected. Half-way retracement.
- 61.8% — The "golden ratio." Most watched level. Strong confluence of buyers/sellers.
- 78.6% — Deep retracement. Often used as final confirmation zone before trend continuation.
How to use them in practice
Identify a clear swing high and swing low. Apply the tool (or this calculator) in the direction of the prior move. Wait for price to retrace to one of the key levels, then look for confirmation (candlestick patterns, volume spike, divergence) before entering in the direction of the original trend.
