Struct yata::methods::LinearVolatility [−][src]
pub struct LinearVolatility { /* fields omitted */ }
Expand description
Calculate moving linear volatility for last length
values of type ValueType
LV = Σ[abs(Derivative
(1))]
Parameters
Has a single parameter length
: PeriodType
length
should be > 0
Input type
Input type is ValueType
Output type
Output type is ValueType
Output is always positive or 0.0
Examples
use yata::prelude::*; use yata::methods::LinearVolatility; // volatility over 3 periods let mut vol = LinearVolatility::new(3, 1.0).unwrap(); vol.next(1.0); vol.next(2.0); assert_eq!(vol.next(3.0), 2.0); assert_eq!(vol.next(1.0), 4.0);
