# Relative Momentum Index (RMI)

> QuantNexus indicator page for momentum-adjusted RSI.

**Route**: `/quantnexus/indicators/rmi/`

## What It Does

RMI extends RSI by comparing current price to a price lookback, making it a momentum-aware oscillator.

## Formula

`RMI = RSI of momentum over the selected lookback`

## Parameters

- `period` - default `20`
- `movav` - default `SmoothedMovingAverage`
- `upperband` - default `70`
- `lowerband` - default `30`
- `safediv` - default `False`
- `safehigh` - default `100`
- `safelow` - default `50`
- `lookback` - default `5`

## C++23 API

```cpp
#include <nonabt/indicators/rmi.hpp>
auto rmi = std::make_unique<nonabt::RMI>(data().close(), 20, "SmoothedMovingAverage", 70.0, 30.0, "False", 100.0, 50.0, 5);
```

## Common Usage

- Use it as a momentum-sensitive RSI variant.
- Pair it with trend confirmation to avoid counter-trend fades.
- Helpful in breakout and continuation systems.
