pub struct TEMA { /* private fields */ }
Expand description
Triple Exponential 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::core::Method;
use yata::methods::TEMA;
// TEMA of length=3
let mut tema = TEMA::new(3, &1.0).unwrap();
tema.next(&1.0);
tema.next(&2.0);
assert_eq!(tema.next(&3.0), 2.9375);
assert_eq!(tema.next(&4.0), 4.0);
§Performance
O(1)
