After a strong move, markets rarely continue in a straight line. They pull back first. The question every trader asks is: how far might this pullback go before the move resumes? Fibonacci retracement is one of the most popular tools for answering it.
What the levels are
The tool takes a completed move, from a swing low to a swing high (or the reverse), and marks the points that sit a certain percentage of the way back. The standard levels are:
- 23.6%: a shallow pullback
- 38.2%: a common pullback in a strong trend
- 50%: not a Fibonacci ratio, but widely watched
- 61.8%: the "golden ratio", the deepest level many traders still consider healthy
- 78.6%: a deep pullback; beyond it, the move is often in doubt
The ratios come from the Fibonacci number sequence. Whether markets truly follow them is debated. What is certain is that many traders watch the same levels, and that alone can make orders cluster there.
How to draw it
In an uptrend, drag the tool from the swing low to the swing high. The levels appear below the high, showing where a pullback might find buyers.
In a downtrend, drag from the swing high to the swing low. The levels appear above the low, showing where a bounce might meet sellers.
Use clear, obvious swings, the ones most traders would pick. A Fibonacci drawn from an arbitrary point is just a set of random lines.
A worked example
Suppose gold rose from 3,900 to 4,100, a move of 200.
| Level | Calculation | Price |
|---|---|---|
| 38.2% | 4,100 − 0.382 × 200 | 4,023.6 |
| 50% | 4,100 − 0.5 × 200 | 4,000.0 |
| 61.8% | 4,100 − 0.618 × 200 | 3,976.4 |
A trader expecting the uptrend to continue might watch the 4,000–3,976 area for signs that buyers are returning.
How traders use it
- As an area, not a line. Treat each level as a zone and wait for confirmation, such as a candlestick rejection.
- Together with other tools. A Fibonacci level that lines up with a support level, a trend line or a moving average is much stronger than one standing alone.
- For stops. A common approach is to place the stop beyond the next Fibonacci level or beyond the start of the move. If price falls through 78.6%, the original move is often considered broken.
Limits worth remembering
- Fibonacci levels do not predict; they highlight places to watch.
- Different traders choose different swings, so their levels differ.
- In a very strong trend, price may not pull back far enough to reach any level at all.
In short
Draw Fibonacci retracement from a clear swing low to a clear swing high (or the reverse). Watch 38.2%, 50% and 61.8% as zones where a pullback might end, and trust them most when they line up with other levels on the chart.
