Fibonacci retracement divides a price move into ratios where traders often expect pullbacks to pause. It's popular, occasionally uncanny — and easy to over-trust.
The levels
Draw the tool from the start of a move to its end, and it marks horizontal levels at:
- 23.6%, 38.2%, 50%, 61.8% and 78.6%
The 61.8% ("the golden ratio") and 50% levels get the most attention as places a healthy pullback might stall before the trend resumes. (50% isn't a true Fibonacci number, but traders watch it anyway.)
Why they sometimes "work"
There's no law of markets here. Fib levels matter partly because so many traders watch the same ones — orders cluster there, creating a self-fulfilling tendency. They work best when they line up with something real.
How to use them sensibly
- Anchor to obvious swings — measure a clear, meaningful move, not random wiggles.
- Look for confluence — a Fib level that overlaps support/resistance, a moving average or a round number is far more reliable than a lonely line.
- Wait for confirmation — a pause and a reaction at the level beats blindly buying the number.
The honest caveat
Two traders will often draw their Fibs differently and get different levels. Treat retracements as zones of interest, not precise prices. Define where you're wrong with a stop just beyond the level, and size the trade with the risk/reward calculator.
A Fib level is a hypothesis. The market's reaction to it is the evidence.
