Fibonacci Extensions: Setting Profit Targets
Fibonacci extensions project where a trend may end, giving you profit targets. Learn the key extension ratios and how to combine them with retracements.
Fibonacci Extensions: Setting Profit Targets
Retracements tell you where to enter. Extensions tell you where to take profit. Together, they're a complete plan.
Fibonacci extensions project price beyond the prior swing, marking where a trend may exhaust. While retracements find entries during pullbacks, extensions find exits during continuation — they answer the question every trader asks: "Where do I take profit?"
The key extension ratios
| Ratio | Meaning |
|---|---|
| 1.0 | 100% extension — equal to the prior move |
| 1.272 | 127.2% — square root of 1.618 |
| 1.618 | 161.8% — the golden extension, most-watched |
| 2.618 | 261.8% — extended trend target |
| 4.236 | 423.6% — major blow-off target |
The 1.618 extension is the king of profit targets. It's where many trends find their first major resistance.
How to draw the extension
Unlike a retracement (two points), an extension uses three points:
- Point A — the start of the move (swing low for uptrend)
- Point B — the end of the move (swing high)
- Point C — the end of the retracement (the swing low after B)
The tool then projects the extension ratios beyond B.
Worked example — uptrend from $40 (A) to $60 (B), retracement to $50 (C):
Move AB = $60 − $40 = $20
Extend from C ($50) by the ratio:
1.618 extension = $50 + (1.618 × $20) = $50 + $32.36 = $82.36
1.272 extension = $50 + (1.272 × $20) = $50 + $25.44 = $75.44
1.000 extension = $50 + (1.000 × $20) = $50 + $20.00 = $70.00
So a long entered near $50 (the 0.5 retracement) would target $82.36 (the 1.618 extension).
How to use extensions
- Set profit targets — once you've entered on a retracement, place limit orders at the 1.272 and 1.618 extensions
- Scale out — take half off at 1.272, trail the rest to 1.618
- Combine with structure — if the 1.618 level aligns with prior resistance, it's far stronger
Retracement + extension = a complete trade
| Stage | Tool | Purpose |
|---|---|---|
| Entry | Retracement (0.5 or 0.618) | Where to buy the pullback |
| Stop | Beyond the next retracement level | Defines risk |
| Target | Extension (1.272 or 1.618) | Defines reward |
Worked example:
| Element | Price |
|---|---|
| Entry (0.5 retracement) | $50 |
| Stop (below 0.618) | $47.50 |
| Target (1.618 extension) | $82.36 |
| Risk | $2.50 |
| Reward | $32.36 |
| RR | ≈ 1:13 |
A strong extension trade can offer massive RR. Verify with the risk-reward calculator and size the order with the position size calculator.
When extensions work best
- In strong, clean trends (confirm with ADX > 25)
- After a shallow retracement (0.382 or 0.5) — deep retracements (0.786) tend to produce weaker continuations
- When the 1.618 level lines up with prior structure (an old swing high, a measured move)
Common mistakes
- Targeting 4.236 routinely — that's a blow-off level, not a normal target
- Forgetting the third point — extensions need A, B, and C
- Holding for the exact level — take partial profits; don't let a winner turn into a loser
- Ignoring the trend — extensions fail in ranges just like retracements
How to start
- Find a trending market on a daily chart
- Mark the swing (A, B) and the retracement low (C)
- Draw the Fibonacci extension tool
- Set targets at 1.272 and 1.618
- Pre-define risk with the stop loss calculator before entering
Summary
Fibonacci extensions give you objective profit targets when a trend resumes. The 1.618 level is the most respected, but scaling out at 1.272 protects you if the trend stalls. Pair extensions with retracement entries and you have a complete, rules-based trade plan.
