# Fractal (FRACTAL)

> QuantNexus indicator page for swing fractal detection.

**Route**: `/quantnexus/indicators/fractal/`

## What It Does

FRACTAL identifies local swing highs and swing lows using a small multi-bar pattern.

## Formula

An up fractal forms when the middle bar is higher than surrounding bars. A down fractal forms when the middle bar is lower than surrounding bars.

## Parameters

- `period` - default `5`

## C++23 API

```cpp
#include <nonabt/indicators/fractal.hpp>
auto fractal = std::make_unique<nonabt::FRACTAL>(data(), 5);
```

## Common Usage

- Use it to mark swing highs and lows.
- Combine with breakout confirmation above or below the fractal level.
- Useful for structure-based trend analysis.
