Struct SimpleMovingAverage 

pub struct SimpleMovingAverage<'a> {
    pub inputs: HashMap<&'a str, Rc<RefCell<Slot>>>,
    pub outputs: HashMap<&'a str, Rc<RefCell<Slot>>>,
    /* private fields */
}

Simple moving average (SMA).

Formula

Where:

• SMA_t - value of simple 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 core::indicators::SimpleMovingAverage;
// use core::Next;

// let mut sma = SimpleMovingAverage::new(3).unwrap();
// assert_eq!(sma.next(10.0), 10.0);
// assert_eq!(sma.next(11.0), 10.5);
// assert_eq!(sma.next(12.0), 11.0);
// assert_eq!(sma.next(13.0), 12.0);
