Struct Sma 

pub struct Sma { /* private fields */ }

Simple Moving Average indicator.

Computes the arithmetic mean of closing prices over the specified period.

Formula

SMA = (P1 + P2 + … + Pn) / n

where P is the closing price and n is the period.

Example

use quant_indicators::{Indicator, Sma};
use quant_primitives::Candle;
use chrono::Utc;
use rust_decimal_macros::dec;

let ts = Utc::now();
let candles: Vec<Candle> = (0..20).map(|i| {
    Candle::new(dec!(100), dec!(110), dec!(90), dec!(100) + rust_decimal::Decimal::from(i), dec!(1000), ts).unwrap()
}).collect();
let sma = Sma::new(20).unwrap();
let series = sma.compute(&candles).unwrap();

Implementations

impl Sma

pub fn new(period: usize) -> Result<Self, IndicatorError>

Create a new SMA indicator with the specified period.

Errors

Returns InvalidParameter if period is 0.

Trait Implementations

impl Clone for Sma

fn clone(&self) -> Sma

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sma

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

Formats the value using the given formatter.

impl Indicator for Sma

fn name(&self) -> &str

The name of this indicator (e.g., “SMA(20)”).

fn warmup_period(&self) -> usize

Minimum number of candles required before output is valid.

fn compute(&self, candles: &[Candle]) -> Result<Series, IndicatorError>

Compute the indicator values from candle data.
