## What It Does

## Parameters

- `period` - default `30`
- `perc` - default `2.5`

## C++23 API

```cpp
#include <nonabt/indicators/wmaenvelope.hpp>
auto wmaEnvelope = std::make_unique<nonabt::WMAENVELOPE>(data().close(), 30, 2.5);
```

## Common Usage

- Use it to detect stretch around a weighted average baseline.
- Pair it with crossover or reversion logic.
- Helpful when you want more recent prices to carry more influence.
