Struct EMA 

pub struct EMA { /* private fields */ }

Incremental EMA — O(1) update, SMA warm-up.

Unlike the batch ema function (which initialises from an SMA over the first period prices), this struct emits its first value after it has accumulated exactly period samples and seeds itself from their average. Both approaches are correct; this one is more natural for streaming use.

Implementations

impl EMA

pub fn new(period: usize) -> Self

pub fn update(&mut self, price: f64)

pub fn value(&self) -> f64

pub fn is_ready(&self) -> bool

pub fn reset(&mut self)
