Fibonacci Retracement is a technical analysis tool used to identify potential support and resistance levels where price corrections might pause or reverse within a trend. It is based on the Fibonacci sequence—a mathematical pattern where each number is the sum of the two preceding ones (0, 1, 1, 2, 3, 5, 8, 13, etc.). The key ratios derived from this sequence are 23.6%, 38.2%, 50%, 61.8%, and 76.4%, which traders plot on price charts to mark potential reversal zones.
To use Fibonacci Retracement, traders first identify a significant price swing—a recent high and low point on the chart. They then plot the Fibonacci levels between these points. When price approaches one of these levels during a pullback or correction, it may act as support (in an uptrend) or resistance (in a downtrend), creating an opportunity to enter or exit a trade in the direction of the overall trend.
The tool's accuracy depends on selecting the right swing points, which can be subjective and vary among traders. Fibonacci levels also produce false signals, especially in choppy or sideways markets. For this reason, traders should use Fibonacci Retracement alongside other technical indicators—such as moving averages or momentum oscillators—to confirm reversal signals. Proper risk management with stop-loss orders is essential when trading around these levels.
