# Adaptive Moving Average Envelope (KAMAENVELOPE)

> QuantNexus indicator page for the KAMA envelope channel.

**Route**: `/quantnexus/indicators/kamaenvelope/`

## What It Does

KAMA Envelope builds an upper and lower band around the adaptive moving average. It is useful for breakout and pullback logic around a responsive center line.

## Formula

`Envelope = KAMA +/- perc%`

## Parameters

- `period` - default `30`
- `fast` - default `2`
- `slow` - default `30`
- `perc` - default `2.5`

## C++23 API

```cpp
#include <nonabt/indicators/kamaenvelope.hpp>
auto kama_env = std::make_unique<nonabt::KAMAENVELOPE>(data().close(), 30, 2, 30, 2.5);
```

## Common Usage

- Use KAMA Envelope for dynamic channel breakouts.
- Combine it with price re-entry logic after pullbacks.
- Helpful in trending markets with adaptive support/resistance.

## Practical Pattern

When price pushes above the upper envelope, the trend may be accelerating; when it falls back inside, momentum may be cooling.
