Map the levels where a pullback is likely to find support or resistance. Enter the swing high and low and pick the trend direction — this returns every key Fibonacci retracement plus extension targets.
FAQ
How are Fibonacci retracement levels calculated?
Take the swing range (high − low) and multiply by each ratio (0.236, 0.382, 0.5, 0.618, 0.786). In an uptrend you subtract from the high; in a downtrend you add to the low.
Which Fibonacci levels matter most?
The 38.2%, 50%, and 61.8% retracements are watched most closely as potential support or resistance. 50% isn't a true Fibonacci ratio but is widely used by traders.
What are Fibonacci extensions?
Extensions like 127.2% and 161.8% project price targets beyond the original swing — useful for setting take-profit levels once price breaks past the prior high or low.
