# Any N (ANYN)

> QuantNexus indicator page for ANYN utility logic.

**Route**: `/quantnexus/indicators/anyn/`

## What It Does

ANYN checks whether any value in the lookback window satisfies the configured condition. It is commonly used as a helper for signal persistence or event detection.

## Formula

ANYN returns true or 1 when at least one observation in the last `n` periods satisfies the configured condition.

## Parameters

- `period` - default `14`

## C++23 API

```cpp
#include <nonabt/indicators/anyn.hpp>
auto anyn = std::make_unique<nonabt::ANYN>(data(), 14);
```

## Common Usage

- Use ANYN as a trigger helper.
- Combine it with thresholds or cross conditions.
- Useful when you only need one qualifying event in the lookback window.

## Practical Pattern

ANYN is a persistence filter for "has the condition occurred at least once" logic.
