# RSI EMA (RSI_EMA)

> QuantNexus indicator page for RSI with exponential smoothing.

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

## What It Does

RSI_EMA calculates RSI using an exponential moving average variant for smoothing.

## Formula

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

## Parameters

- `period` - default `14`
- `movav` - default `ExponentialMovingAverage`
- `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_ema.hpp>
auto rsiEma = std::make_unique<nonabt::RSI_EMA>(data().close(), 14, "ExponentialMovingAverage", 70.0, 30.0, "False", 100.0, 50.0, 1);
```

## Common Usage

- Use it like RSI but with EMA-style smoothing.
- Pair it with overbought/oversold thresholds.
- Helpful when you want a faster-reacting RSI variant.
