What is it?
Fibonacci retracement is a technical analysis tool that uses horizontal lines at the key Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, and 78.6%) to identify potential support and resistance levels where a price correction might reverse. These ratios are derived from the Fibonacci sequence.
How to use
Identify a significant swing high and swing low on the chart. Enter these values, and the calculator computes the retracement levels. In a downtrend pullback, these levels act as potential resistance; in an uptrend pullback, they act as potential support.
Example scenario
Swing high = $180, swing low = $120, range = $60. The 38.2% retracement = $180 รขหโ $60 รโ 0.382 = $157.08. The 61.8% retracement = $180 รขหโ $60 รโ 0.618 = $142.92. Traders watch these levels for buying opportunities in an uptrend.
Pro tip
The 61.8% level (golden ratio) and 50% level tend to be the most significant. When a Fibonacci level coincides with another form of support/resistance (moving average, pivot point, prior swing), the "confluence" makes the level much stronger.
