Struct StochasticOscillator

pub struct StochasticOscillator { /* private fields */ }

A Stochastic Oscillator indicator.

Implementations

impl StochasticOscillator

pub const DEFAULT_PERIOD: usize = 14usize

Default %K period (typically 14).

pub const DEFAULT_K_SMOOTH: usize = 3usize

Default %K smoothing period (typically 3).

pub const DEFAULT_D_PERIOD: usize = 3usize

Default %D period (typically 3).

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

Creates a new StochasticOscillator with the given parameters.

Arguments

• period - The period for %K calculation.
• k_smooth - The smoothing period for %K.
• d_period - The period for %D calculation.

pub fn calculate(&mut self, price: f64) -> Option<StochResult>

Updates the oscillator with a new price and returns the current oscillator result.

The oscillator calculates the raw %K value based on the current window of prices, applies smoothing if enough values exist, and then computes the %D value. It also generates a trading signal, a condition, and detects a crossover.

Arguments

• price - The latest price.

Returns

• Some(StochResult) if there is sufficient data, else None.
