Fibonacci Retracement Calculator

Key retracement levels calculated from the real 3-month high and low for any ticker.

Levels calculated between the real 3-month high and low. Data via Yahoo Finance.

This tool fetches the real 3-month high and low for the ticker you enter, then calculates the standard Fibonacci retracement levels — 23.6%, 38.2%, 50%, 61.8%, and 78.6% — between them.

These levels are widely used as reference points for potential support and resistance, though they work best combined with other confirmation signals rather than in isolation.

FAQ

What are Fibonacci retracement levels used for?
Traders use them to identify potential support levels during a pullback in an uptrend, or resistance levels during a bounce in a downtrend, based on ratios derived from the Fibonacci sequence.
Which level is most watched?
The 61.8% ('golden ratio') and 50% levels are the most commonly watched, though all five levels are used to identify zones of potential reaction.
