Fibonacci Retracing Levels

Fibonacci retracement levels are a set of horizontal lines drawn on a chart to mark places where a price pullback might pause or reverse before the prior trend continues. They are not based on news, volume, or anything fundamental to the asset — they come from a mathematical sequence (the Fibonacci sequence) that produces a handful of recurring ratios, most commonly 23.6%, 38.2%, 50%, 61.8%, and 78.6%.

To use the tool, a trader picks two significant points on a chart, typically a swing low and a swing high (or vice versa), and draws a line between them. Charting software then automatically slices that vertical distance into the Fibonacci percentages and plots them as horizontal lines. If a stock rallied from $50 to $60, the 50% retracement level would sit at $55, meaning the price has given back half of that $10 move. Traders watch these lines to see whether a pullback stalls near one of them, which some interpret as a sign that the original trend may resume.

The nuance that trips up beginners is that these levels are not support or resistance in any mechanical or guaranteed sense — no exchange rule or order-matching mechanism makes price behave this way. They work, when they work, because enough traders are watching the same lines and placing orders around them, which can become a bit self-fulfilling. There is nothing that forces price to stop at 61.8% instead of 38.2% or blowing through all of them entirely.

Because of that, Fibonacci levels are best treated as one input among several — combined with candlestick patterns, volume, moving averages, or trendlines — rather than a standalone signal to buy or sell. Drawing them on the "wrong" two points (an insignificant high or low) also produces levels that mean little, so choosing the anchor points itself takes judgment and practice.
