Fibonacci Retracement Calculator
Plot the key Fibonacci levels for any move. Enter a swing high and low, pick the trend direction, and get the 23.6–78.6% retracements plus the common extension targets.
The swing
Retracements mark where a pullback may find support (uptrend) or resistance (downtrend). The 0.382–0.618 zone is the most-watched. Extensions project targets past the prior swing.

How it works
Fibonacci retracements mark where a pullback within a trend often finds support (in an uptrend) or resistance (in a downtrend). The most-watched levels are 38.2%, 50% and 61.8% — the "golden" zone where many traders look to enter in the direction of the larger trend.
Extensions (127.2%, 161.8% and beyond) project where a move might travel once it clears the prior swing, which makes them useful for profit targets. Like pivots, fib levels work partly because so many traders watch them — treat them as a confluence tool alongside structure and volume, not a standalone signal.
Pair these levels with the patterns StockSetups detects: a bull flag retracing to its 50% fib into prior support is a far stronger setup than the fib level alone.
Frequently asked
What are the Fibonacci retracement levels?
The standard levels are 23.6%, 38.2%, 50%, 61.8% and 78.6%. The 38.2–61.8% zone is the most watched for pullback entries in the direction of the trend.
How do you use Fibonacci retracements?
Identify a clear swing high and low, then plot the retracements. In an uptrend, look for support and a possible entry near the 38.2–61.8% levels; in a downtrend, look for resistance there. Extensions (127.2%, 161.8%) act as targets.
What's the difference between retracement and extension?
Retracements (0–100%) measure how far a pullback travels within the prior move; extensions (above 100%) project how far the next move might run beyond the prior swing, useful as targets.
