Fibonacci levels projected BEYOND the original swing (127.2%, 161.8%, 261.8%) — used to set price targets after breakouts.
Fibonacci extensions project Fibonacci ratios beyond the end of a prior price swing. They're used to find profit targets. The most common extension levels are 127.2%, 161.8% (the "golden ratio extension"), 200%, and 261.8%. These levels often mark where extended trends pause or reverse.
The drawing technique uses three points: swing low, swing high, and then the pullback low (in an uptrend). The tool then projects the extension above the swing high. The 161.8% extension is the most-watched target — many institutional algos use it as a take-profit anchor.
Extensions are most useful in trending markets with clear impulse-pullback-impulse structure. They give you measurable targets instead of guessing where to take profit.
