## What It Does

SMA is the simplest moving average. It smooths price by averaging the last `n` observations equally.

## Formula

`SMA = (P1 + P2 + ... + Pn) / n`

## Parameters

- `period` - default `30`

## C++23 API

```cpp
#include <nonabt/indicators/sma.hpp>
auto sma = std::make_unique<nonabt::SMA>(data().close(), 30);
```

## Common Usage

- Use SMA as a baseline trend line.
- Use SMA crossovers for simple trend systems.
- Use SMA as the center line for channel indicators.

## Practical Pattern

SMA is slower than EMA but often cleaner for longer-horizon trend confirmation.
