Struct yata::methods::SMA

pub struct SMA { /* fields omitted */ }

Simple Moving Average of specified length for timeseries of type ValueType

Parameters

Has a single parameter length: PeriodType

length should be > 0

Input type

Input type is ValueType

Output type

Output type is ValueType

Examples

use yata::prelude::*;
use yata::methods::SMA;

// SMA of length=3
let mut sma = SMA::new(3, 1.0);

sma.next(1.0);
sma.next(2.0);

assert_eq!(sma.next(3.0), 2.0);
assert_eq!(sma.next(4.0), 3.0);
