Struct yata::methods::VWMA [−][src]
pub struct VWMA { /* fields omitted */ }
Expand description
Volume Weighed Moving Average of specified length
for timeseries of type (ValueType
, ValueType
) which represents pair of values (value
, volume
)
Parameters
length
should be > 0
Has a single parameter length
: PeriodType
Input type
Input type is ValueType
Output type
Output type is ValueType
Examples
use yata::prelude::*; use yata::methods::VWMA; // VWMA of length=3 let mut vwma = VWMA::new(3, (3.0, 1.0)).unwrap(); // input value is a pair of f64 (value, weight) vwma.next((3.0, 1.0)); vwma.next((6.0, 1.0)); assert_eq!(vwma.next((9.0, 2.0)), 6.75); assert!((vwma.next((12.0, 0.5))- 8.571428571428571).abs() < 1e-10);
