Struct AcceleratorOscillator 

pub struct AcceleratorOscillator { /* private fields */ }

Accelerator Oscillator — Bill Williams’ gauge of momentum’s acceleration.

AO = SMA(median, fast) − SMA(median, slow)   (the Awesome Oscillator)
AC = AO − SMA(AO, signal)

Where the AwesomeOscillator tracks momentum, the Accelerator tracks the change in momentum: it is the AO minus a short moving average of itself. Because acceleration leads speed, AC tends to turn before the AO does. Bill Williams’ classic configuration is the (5, 34) AO with a 5-period signal average.

Example

use wickra_core::{Candle, Indicator, AcceleratorOscillator};

let mut indicator = AcceleratorOscillator::classic();
let mut last = None;
for i in 0..80 {
    let base = 100.0 + f64::from(i);
    let candle =
        Candle::new(base, base + 2.0, base - 2.0, base + 1.0, 10.0, i64::from(i)).unwrap();
    last = indicator.update(candle);
}
assert!(last.is_some());

Implementations

impl AcceleratorOscillator

pub fn new(ao_fast: usize, ao_slow: usize, signal_period: usize) -> Result<Self>

Construct an Accelerator Oscillator with explicit AO and signal periods.

Errors

Returns Error::PeriodZero for a zero period and Error::InvalidPeriod if the AO fast period is not strictly below slow.

pub fn classic() -> Self

Bill Williams’ classic configuration: AO(5, 34) with a 5-period signal.

pub const fn params(&self) -> (usize, usize, usize)

Configured (ao_fast, ao_slow, signal_period).

Trait Implementations

impl Clone for AcceleratorOscillator

fn clone(&self) -> AcceleratorOscillator

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AcceleratorOscillator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Indicator for AcceleratorOscillator

type Input = Candle

Type of one input data point (typically f64 for a price, or Candle / Tick).

type Output = f64

Type of one output value.

fn update(&mut self, candle: Candle) -> Option<f64>

Feed one new data point into the indicator and return the freshly computed output, or None if the indicator is still warming up.

fn reset(&mut self)

Reset all internal state, leaving the indicator equivalent to a freshly constructed instance with the same parameters.

fn warmup_period(&self) -> usize

Number of inputs required before the first non-None output can be produced.

fn is_ready(&self) -> bool

Whether the indicator has emitted at least one value since the last reset.

fn name(&self) -> &'static str

Stable, human-readable indicator name. Used by chaining and diagnostics.
