Fibonacci extensions project where a trend might go after it moves beyond its previous high or low. While retracements estimate how deep a pullback might be, extensions estimate how far the next leg might travel. Common extension levels are 127.2%, 161.8%, 200% and 261.8%. Traders use them mainly to set profit targets in trending markets, especially when price is making new highs and there are no previous levels above to use.

## Extensions vs projections

The terms are often used loosely, but there are two distinct methods:

| Method | Points used | Measures |
|---|---|---|
| Extension | Two points: the start and end of a move | How far beyond the move's end price might go, as a multiple of that move |
| Projection | Three points: start of a move, end of the move, end of the pullback | The next leg projected from the pullback low, as a multiple of the first leg |

Most charting platforms call the three point tool a "trend based Fibonacci extension".

## Calculating a two point extension

**Example: Extension from a single move**
A stock rises from $40 to $60, a $20 move, then pulls back.
127.2% extension: $40 + 1.272 × $20 = $65.44.
161.8% extension: $40 + 1.618 × $20 = $72.36.
261.8% extension: $40 + 2.618 × $20 = $92.36.
If price breaks above $60, these become potential targets.

## Calculating a three point projection

**Example: Projection from the pullback**
The same stock rises from $40 to $60 (first leg $20), pulls back to $50, then starts rising.
100% projection: $50 + 1.000 × $20 = $70, a second leg equal to the first.
161.8% projection: $50 + 1.618 × $20 = $82.36.
61.8% projection: $50 + 0.618 × $20 = $62.36, a shorter second leg.

The 100% projection, where the second leg equals the first, is sometimes called a measured move or AB=CD pattern and is one of the most watched targets.

## Common levels and their use

| Level | Typical use |
|---|---|
| 61.8% (projection) | Conservative first target for a weaker second leg |
| 100% (projection) | Equal legs; common target |
| 127.2% (extension) | First target beyond the prior high |
| 161.8% | Popular main target in strong trends |
| 261.8% | Extended target in very strong trends or parabolic moves |

## Using extensions in practice

1. **Use them for targets, not entries.** Extensions suggest where a move might pause, not where to start a trade.
2. **Take partial profits** at the first extension and trail the rest. See [Profit Targets](https://learn.tradelabsai.com/position-management/profit-targets/) and [Scaling Out and Partial Profits](https://learn.tradelabsai.com/position-management/scaling-out-and-partial-profits/).
3. **Look for confluence** with round numbers, previous highs on higher timeframes or measured moves from patterns.
4. **Watch price action at the level:** rejection candles or slowing momentum near an extension suggest the move may be ending.

## Limitations

- **Many levels, many outcomes:** with several extension levels, price will nearly always end near one of them, making them look more accurate in hindsight than in real time.
- **Point selection is subjective:** different swing points give different targets.
- **Strong trends overshoot:** in powerful moves, price can blow through all common levels.

## Common mistakes

- **Shorting at an extension level** in a strong trend just because it was "hit".
- **Choosing swing points after the fact** to make levels fit.
- **Ignoring volatility:** in highly volatile markets, targets should be treated as wide zones.

## Frequently asked questions

### What are Fibonacci extensions used for?

Mainly for setting profit targets beyond a previous high or low, estimating how far the next leg of a trend might travel.

### What is the most common Fibonacci extension level?

The 161.8% level is widely watched, along with 127.2% and the 100% projection where the second leg equals the first.

### What is the difference between Fibonacci extension and projection?

An extension uses two points and projects a multiple of one move from its start. A projection uses three points and projects the first leg's size from the end of the pullback.
