Struct BollingerParams 

pub struct BollingerParams {
    pub period: usize,
    pub num_std: f64,
    pub stdev: StdevKind,
}

Bollinger parameter pack.

Fields

period: usize

num_std: f64

Multiplier on window stdev (typically 2.0).

stdev: StdevKind

Sample (n−1) or population (n) stdev. Default: sample.

Implementations

impl BollingerParams

pub const fn standard() -> Self

(20, 2.0, Sample) — common default.

pub const fn new(period: usize, num_std: f64) -> Self

Sample stdev (same as setting stdev: Sample).

pub const fn with_stdev(period: usize, num_std: f64, stdev: StdevKind) -> Self
