Struct Sma 

pub struct Sma<const N: usize> { /* private fields */ }

Simple Moving Average over a fixed window of N prices.

Keeps a rolling sum so each update is O(1); the sum is reseeded from the live window every 16 · N finite updates to bound floating-point drift, exactly as wickra_core::Sma does. Output is sum / N once the window is full, None before.

Example

use wickra_embed_core::{Indicator, Sma};

let mut sma = Sma::<3>::new();
assert_eq!(sma.update(1.0), None);
assert_eq!(sma.update(2.0), None);
assert_eq!(sma.update(3.0), Some(2.0));
assert_eq!(sma.update(4.0), Some(3.0));

Implementations

impl<const N: usize> Sma<N>

pub const fn new() -> Self

Construct a new SMA over a window of N.

pub fn value(&self) -> Option<f64>

Current value if the window is full.

Trait Implementations

impl<const N: usize> Clone for Sma<N>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const N: usize> Debug for Sma<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<const N: usize> Default for Sma<N>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: usize> Indicator for Sma<N>

type Input = f64

Type of one input data point (f64 for a price, Candle for an OHLC bar).

fn update(&mut self, input: f64) -> Option<f64>

Feed one new data point in and return the freshly computed value, or None while still warming up.

fn reset(&mut self)

Reset all internal state, leaving the indicator equivalent to a freshly constructed instance with the same parameters.

fn warmup_period(&self) -> usize

Number of inputs required before the first non-None output.

fn is_ready(&self) -> bool

Whether the indicator has produced at least one value since construction or the last reset.

fn name(&self) -> &'static str

Stable, human-readable indicator name.
