# Stochastic Fast (STOCHF)

> QuantNexus indicator page for the fast stochastic oscillator.

**Route**: `/quantnexus/indicators/stochf/`

## What It Does

STOCHF measures the close position within the recent high-low range and applies a fast smoothing step.

## Formula

`%K = 100 * (Close - Lowest Low(n)) / (Highest High(n) - Lowest Low(n))`

## Parameters

- `period` - default `14`
- `period_dfast` - default `3`
- `movav` - default `MovingAverageSimple`
- `upperband` - default `80`
- `lowerband` - default `20`
- `safediv` - default `False`
- `safezero` - default `0`

## C++23 API

```cpp
#include <nonabt/indicators/stochf.hpp>
auto stochF = std::make_unique<nonabt::STOCHF>(14, 3, "MovingAverageSimple", 80.0, 20.0, "False", 0);
```

## Common Usage

- Use it for short-term momentum and reversal detection.
- Pair it with price structure or trend filters.
- Helpful when you want a faster oscillator than full stochastic.
