Struct yata::methods::RateOfChange
source · [−]pub struct RateOfChange(_);
Expand description
Rate of change calculates relative difference between current
value and n-th value back, where n = length
ROC
= (value
- n_th_value
) / n_th_value
ROC
= Momentum
/ n_th_value
Parameters
Has a single parameter length
: PeriodType
length
should be > 0
Input type
Input type is ValueType
Input value should always be greater than 0.0.
(value
> 0.0
)
Output type
Output type is ValueType
Performance
O(1)
