# RSI SMA (RSI_SMA)

> QuantNexus indicator page for RSI with simple smoothing.

**Route**: `/quantnexus/indicators/rsi-sma/`

## What It Does

RSI_SMA calculates RSI using a simple moving average variant for smoothing.

## Formula

`RSI = 100 - [100 / (1 + RS)]`, with simple smoothing applied to the gain/loss series.

## Parameters

- `period` - default `14`
- `movav` - default `MovingAverageSimple`
- `upperband` - default `70`
- `lowerband` - default `30`
- `safediv` - default `False`
- `safehigh` - default `100`
- `safelow` - default `50`
- `lookback` - default `1`

## C++23 API

```cpp
#include <nonabt/indicators/rsi_sma.hpp>
auto rsiSma = std::make_unique<nonabt::RSI_SMA>(data().close(), 14, "MovingAverageSimple", 70.0, 30.0, "False", 100.0, 50.0, 1);
```

## Common Usage

- Use it when you want the Cutler-style RSI variant.
- Pair it with static threshold logic around 30 and 70.
- Useful for comparing smoothing behavior against EMA-based RSI.
