Fibonacci Retracement
Education only · our voice · free public data
Definition
Horizontal support/resistance levels drawn at Fibonacci ratios (23.6%, 38.2%, 50%, 61.8%, 78.6%) of a prior move — used to anticipate where a pullback may find support before the trend resumes.
How to read it
After a strong advance, price often retraces part of the move before continuing; Fibonacci ratios mark the levels where reactions cluster. The 38.2%–61.8% band is the common 'pullback buy-zone' in an uptrend, with the 61.8% ('golden ratio') the deepest retracement that still respects the trend. Retracements are reference zones, not precise triggers — they work best when a level coincides with other structure and is confirmed by price action, not bought blindly.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Fibonacci confluence/cluster zones: overlay retracements from two or three different swings — where several ratios stack within a tight band, the zone is far higher-probability than any single 61.8% level. Confluence with a moving average, a prior breakout shelf, or a volume-at-price node upgrades a retracement from a line to a genuine decision zone. Use the retracement depth to grade trend health — successive pullbacks getting shallower (holding 38.2% then 23.6%) signals strengthening demand, while deepening retracements warn of fading momentum.
