Struct AdaptiveMovingAverage

#[repr(C)]
pub struct AdaptiveMovingAverage {
    pub period_efficiency_ratio: usize,
    pub period_fast: usize,
    pub period_slow: usize,
    pub price_type: PriceType,
    pub value: f64,
    pub count: usize,
    pub initialized: bool,
    /* private fields */
}

An indicator which calculates an adaptive moving average (AMA) across a rolling window. Developed by Perry Kaufman, the AMA is a moving average designed to account for market noise and volatility. The AMA will closely follow prices when the price swings are relatively small and the noise is low. The AMA will increase lag when the price swings increase.

Fields

period_efficiency_ratio: usize

The period for the internal EfficiencyRatio indicator.

period_fast: usize

The period for the fast smoothing constant (> 0).

period_slow: usize

The period for the slow smoothing constant (> 0 < period_fast).

price_type: PriceType

The price type used for calculations.

value: f64

The last indicator value.

count: usize

The input count for the indicator.

initialized: bool
