# Aroon Up Down Oscillator (AROONUPDOWNOSC)

> QuantNexus indicator page for the Aroon Up Down Oscillator.

**Route**: `/quantnexus/indicators/aroonupdownosc/`

## What It Does

This oscillator summarizes the difference between the up and down components of Aroon into a single momentum-style line.

## Formula

`Aroon Up Down Oscillator = Aroon Up Down structure condensed into one directional oscillator`

## Parameters

- `period` - default `14`
- `upperband` - default `70`
- `lowerband` - default `30`

## C++23 API

```cpp
#include <nonabt/indicators/aroonupdownosc.hpp>
auto aroonupdownosc = std::make_unique<nonabt::AROONUPDOWNOSC>(data(), 14, 70, 30);
```

## Common Usage

- Use it as a directional oscillator.
- Combine it with zero-line or threshold logic.
- Useful for trend pressure confirmation.

## Practical Pattern

Positive oscillator values usually imply stronger upward recency; negative values usually imply stronger downward recency.
