# OLS Slope Intercept N (OLS_SLOPE_INTERCEPTN)

> QuantNexus indicator page for rolling regression slope and intercept.

**Route**: `/quantnexus/indicators/ols-slope-interceptn/`

## What It Does

OLS_SLOPE_INTERCEPTN fits a rolling ordinary least squares line and exposes slope and intercept values.

## Formula

`y = slope * x + intercept`

## Parameters

- `period` - default `10`
- `prepend_constant` - default `True`

## C++23 API

```cpp
#include <nonabt/indicators/ols_slope_interceptn.hpp>
auto ols = std::make_unique<nonabt::OLS_SLOPE_INTERCEPTN>(data().close(), 10, "True");
```

## Common Usage

- Use slope to gauge trend direction and steepness.
- Use intercept as the rolling regression baseline.
- Helpful for trend diagnostics and linear-fit analysis.
