The shaded 38.2–61.8% rows are the zone most traders watch. Treat a level as a place to look, not a signal on its own.

<p style="font-size:13px">Fibonacci Calculator by <a href="https://stocksetups.com/tools/fibonacci-calculator">StockSetups</a></p>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.
Does the swing high have to be an all-time high?
No. Use the most recent clear swing you're trading, whether that's a move of days or months. Different traders pick different swings, which is one reason levels vary from chart to chart.
How often does the 61.8% level hold?
There's no reliable fixed probability. Any level can hold or fail, and results depend on the market, the timeframe and which swing you measured. Treat it as a place to look for confirmation, not as odds.
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.
