Struct WmaEngine 

pub struct WmaEngine { /* private fields */ }

Weighted Moving Average (WMA) over the closing price.

Linearly weighted over the last period closes: weight period on the most recent close down to 1 on the oldest, divided by the weight sum period * (period + 1) / 2.

First output: with the period-th bar. Indicator::reset clears the window.
