Struct MovingAverage

pub struct MovingAverage {
    pub cached: Vec<f64>,
    /* private fields */
}

moving average (ma).

Formula

Where:

• MA_t - value of moving average at a point of time t
• n - number of periods (length)
• p_t - input value at a point of time t

Parameters

• n - number of periods (integer greater than 0)

Example

use quantaxis_rs::indicators::MovingAverage;
use quantaxis_rs::Next;

let mut ma = MovingAverage::new(3).unwrap();
assert_eq!(ma.next(10.0), 0.0);
assert_eq!(ma.next(11.0), 0.0);
assert_eq!(ma.next(12.0), 11.0);
assert_eq!(ma.next(13.0), 12.0);

Fields

cached: Vec<f64>
