The Fibonacci Retracement Formulas
Where Ratio represents key mathematical percentages: 0.236, 0.382, 0.500, 0.618, and 0.786. Extensions use multipliers like 1.618 and 2.618.
Core Fibonacci Retracement Inputs & Terminology
The peak high price or trough low price established during a distinct market price trend.
The primary mathematical ratio derived from the Fibonacci sequence, widely considered the most critical retracement support level.
Price target projections beyond 100% of the initial swing, used to forecast profit targets during trend continuation.
While not a mathematical Fibonacci ratio, the 50% level is a standard market pullback target recognized in Dow Theory.
