Fibonacci Extensions
Once you're in a trade, extensions tell you where to take profit.
Researched and written by Laurent Retracements vs Extensions
There's a simple conceptual split:
- Retracements: "How far back will price pull before continuing the trend?" (Entry tool)
- Extensions: "How far will the next leg of the trend travel?" (Profit target tool)
You use retracements to find where to enter. You use extensions to plan where to exit.
Drawing a Fibonacci Extension
Extensions require three points (many platforms call this the "Fibonacci Expansion" tool):
- Point A: The swing low (start of the move)
- Point B: The swing high (end of the move)
- Point C: The end of the retracement (where the pullback found support)
The tool then projects the extension levels (127.2%, 161.8%, 261.8%) from Point C upward.
The Key Extension Levels
| Level | Common Name | Use |
|---|---|---|
| 127.2% | First extension | Conservative profit target. Common partial take-profit level. |
| 161.8% | The "full extension" | Primary profit target. Most-used level for swing trade exits. |
| 261.8% | Extended target | Used in very strong trends or for "runner" positions. |
EUR/USD rallies from a swing low at 1.0600 (Point A) to a swing high at 1.1000 (Point B): a 400-pip move.
The pullback then bottoms at 1.0750 (Point C).
127.2% extension = 1.0750 + (1.272 × 0.0400) = about 1.1259
161.8% extension = 1.0750 + (1.618 × 0.0400) = about 1.1397
Traders typically set take-profit orders slightly before these levels (for example 1.1250 and 1.1390) so that a near-miss does not leave the trade open.
Practical Application: Combining with Retracements
The complete Fibonacci trade setup looks like this:
- Identify a strong swing (A to B).
- Price pulls back to a Fibonacci retracement level (38.2% or 61.8%) = potential entry at Point C.
- Enter at the retracement level, placing your stop below the retracement zone.
- Set your profit target at the 127.2% or 161.8% extension.
This creates a trade with a defined entry, defined stop-loss, and defined target, all derived from the same Fibonacci tool applied to the same swing.
Don't Over-Engineer It
Fibonacci extensions are a planning tool. They identify potential targets. Not every trade will reach its 161.8% extension. Market structure, news events, and simply changing conditions mean you need to manage the trade dynamically, not just set a target and walk away. Use extensions as a guide, not a guarantee.
Key Takeaways
- • Extensions project targets BEYOND the original swing, unlike retracements which measure pullbacks.
- • Key extension levels: 127.2%, 161.8%, 261.8%.
- • Draw using three points: swing low, swing high, and the retracement low.
- • The 161.8% extension (the "full extension") is the most-watched profit target level.
