Struct VolumeSignalIndicator 

pub struct VolumeSignalIndicator { /* private fields */ }

Volume anomaly indicator.

Classifies each candle’s volume relative to a rolling mean of the prior lookback candles. Returns None until sufficient history is available.

Implements ClassificationIndicator<VolumeSignal>.

Implementations

impl VolumeSignalIndicator

pub fn new(config: VolSignalConfig) -> Result<Self, IndicatorError>

Create a new VolumeSignal indicator.

Errors

Returns InvalidParameter if lookback is 0 or elevated_threshold is not positive.

pub fn compute( &self, candles: &[Candle], ) -> Result<Vec<Option<VolumeSignal>>, IndicatorError>

Convenience wrapper — delegates to the ClassificationIndicator trait impl.

Callers that hold a concrete VolumeSignalIndicator can call .compute() without importing the trait.

Trait Implementations

impl ClassificationIndicator<VolumeSignal> for VolumeSignalIndicator

fn lookback(&self) -> usize

Number of prior candles consumed before first Some result is emitted.

fn compute( &self, candles: &[Candle], ) -> Result<Vec<Option<VolumeSignal>>, IndicatorError>

Classify each candle. Returns one Option<T> per input candle.
