## What It Does

REDUCEN is a reduce-style helper indicator used for aggregate operations over a rolling window.

## Formula

`Output = aggregated value over the selected period`

## Parameters

- `period` - default `14`

## C++23 API

```cpp
#include <nonabt/indicators/reducen.hpp>
auto reduceN = std::make_unique<nonabt::REDUCEN>(data().close(), 14);
```

## Common Usage

- Use it as a derived-data helper.
- Keep downstream interpretation explicit.
- Best suited to internal analysis pipelines rather than direct execution logic.
