Fibonacci retracement is one of the most widely used tools in technical analysis. It helps traders identify potential support and resistance levels where price might reverse during a pullback. The levels are derived from the Fibonacci sequence — a mathematical pattern found throughout nature and, as it turns out, financial markets.
Concept: The Key Fibonacci Levels
The most important Fibonacci retracement levels are 23.6%, 38.2%, 50%, 61.8%, and 78.6%. These percentages represent how far price has pulled back from a recent swing high to swing low (or vice versa).
- 23.6%: A shallow retracement. Often seen in strong trending moves where buyers or sellers step in early.
- 38.2%: A moderate pullback. Common in healthy trends — price retraces, finds support, then continues.
- 50%: Not technically a Fibonacci number, but widely watched. Many traders expect at least a 50% retracement before the trend resumes.
- 61.8%: The "golden ratio." This is the most significant level. A bounce here often signals the trend is still intact. A break through it can mean the trend is weakening.
- 78.6%: A deep retracement. If price pulls back this far, the original trend is under serious pressure.
How to Draw Fibonacci Retracement
On your charting platform, select the Fibonacci retracement tool. For an uptrend, click on the swing low and drag to the swing high. For a downtrend, click on the swing high and drag to the swing low. The tool will automatically plot the retracement levels between those two points.
The key is choosing significant swing points — not every minor wiggle, but clear turning points that are obvious on the chart. The more obvious the swing points, the more likely other traders are watching the same levels, which makes them more effective.
Example: Trading the 61.8% Level
Imagine the FTSE 100 rallies from 7,400 to 7,600 — a 200-point move. You draw your Fibonacci retracement from the low to the high. The 61.8% level sits at 7,476 (7,600 minus 200 times 0.618 equals 7,476).
Price pulls back and stalls right at 7,476. You see a bullish candlestick pattern forming. This is a potential long entry — the trend is up, price has retraced to the golden ratio, and buyers are showing up. You place your stop just below the 78.6% level and target the previous high at 7,600 or above.
Where Fibonacci Works Best
Fibonacci retracement works best in trending markets. In a strong uptrend, you draw from swing low to swing high and look for buying opportunities at the retracement levels. In a downtrend, you draw from swing high to swing low and look for selling opportunities.
It works less well in choppy, range-bound markets where there is no clear trend. If price is just bouncing between two levels with no directional bias, Fibonacci levels will be hit randomly and will not provide reliable signals.
Fibonacci is most powerful when combined with other forms of analysis. If a 61.8% retracement level coincides with a previous support zone, a moving average, and a round number — that is called confluence, and it significantly increases the probability of a reaction at that level.
Warning: Fibonacci Is Not Magic
Fibonacci levels are not guaranteed reversal points. Price does not have to respect any particular level, and sometimes it will slice through all of them. Use Fibonacci as one tool among many — never as your sole reason for entering a trade. Always combine it with price action confirmation and proper risk management.
