Retracements measure the pullback; extensions project continuation targets beyond the swing. The 50–61.8% band is highlighted because reactions cluster in that pocket — see the course for how to trade it with defined risk.
How the math works
The calculator measures your swing (high − low), then marks levels at fixed fractions of it. Uptrend: levels ladder down from the high (high − range × ratio). Downtrend: they ladder up from the low. Extensions project beyond the swing (low + range × 1.272, etc.) as continuation targets. Levels are only as good as the swing you measure — anchor to the dominant impulse, wick to wick.
Learn to actually trade these levels
A level is a zone of interest, not a signal. The free six-lesson course covers anchoring the tool correctly, why the golden zone earns its reputation, a complete pullback playbook with stops and targets — and the regimes where every level fails.

How do you calculate Fibonacci retracement levels?
Measure the swing: range = swing high − swing low. In an uptrend, each retracement level = high − (range × ratio) for the ratios 0.236, 0.382, 0.5, 0.618 and 0.786. In a downtrend, levels = low + (range × ratio). This calculator does both directions and prints every level from your two inputs.
What are Fibonacci extensions and how are they calculated?
Extensions project continuation targets beyond the measured swing. In an uptrend, extension = low + (range × ratio) for ratios like 1.272 and 1.618 — i.e. targets above the swing high. Traders commonly use them as take-profit objectives after a successful retracement entry.
What is the golden zone?
The pocket between the 50% and 61.8% retracement levels. Reactions cluster in this band rather than at one exact price, so trend-continuation traders treat it as a single zone of interest — deep enough to reset momentum, shallow enough that the trend structure survives.
Does this calculator work for gold and indices?
Yes. The math is instrument-agnostic — enter any swing high and low (XAU/USD, US500, any forex pair) and the levels are exact. Output precision follows the precision of your inputs.
Do Fibonacci levels guarantee a reversal?
No. A level is a zone where a reaction is more likely, not a barrier. Levels fail routinely — on strong trend days and around news they fail by default — which is why they must be paired with a confirmation trigger and a stop-loss. The free course linked on this page covers exactly that.
Breakout Alerts watches the levels across 12 instruments and every timeframe, and alerts you the moment price actually reaches and reacts — entry, stop and target attached. Every result published weekly, losses included.
