Struct StochasticOscillator

pub struct StochasticOscillator { /* private fields */ }

Stochastic Oscillator Calculator

The Stochastic Oscillator is a momentum indicator that shows the location of the close relative to the high-low range over a set number of periods.

%K = (Current Close - Lowest Low) / (Highest High - Lowest Low) * 100 %D = SMA of %K over smoothing period

Typical settings: (14, 3, 3) or (5, 3, 3) for faster signals

Implementations

impl StochasticOscillator

pub fn new( period: usize, k_smooth: usize, d_period: usize, ) -> Result<Self, StochasticError>

Creates a new Stochastic Oscillator with specified parameters

Arguments

• period - Lookback period for high/low (typically 14)
• k_smooth - Smoothing period for %K (typically 3)
• d_period - Period for %D calculation (typically 3)

pub fn default() -> Self

Creates a new Stochastic Oscillator with default parameters (14, 3, 3)

pub fn update(&mut self, data: OHLCData) -> Option<StochasticResult>

Updates the oscillator with OHLC data

pub fn update_hlc( &mut self, high: f64, low: f64, close: f64, ) -> Option<StochasticResult>

Updates with separate high, low, close values

pub fn value(&self) -> Option<StochasticResult>

Returns the current Stochastic values

pub fn reset(&mut self)

Resets the oscillator

pub fn is_ready(&self) -> bool

Checks if the oscillator is ready (has enough data)

pub fn period(&self) -> usize

Get the period

pub fn calculate_batch( period: usize, k_smooth: usize, d_period: usize, data: &[OHLCData], ) -> Result<Vec<Option<StochasticResult>>, StochasticError>

Batch calculation for historical data

pub fn fast(period: usize) -> Result<Self, StochasticError>

Fast Stochastic (no smoothing)

pub fn slow(period: usize) -> Result<Self, StochasticError>

Slow Stochastic (standard smoothing)

pub fn full( period: usize, k_smooth: usize, d_period: usize, ) -> Result<Self, StochasticError>
