Struct BbPrimIndicator 

pub struct BbPrimIndicator {
    pub period: usize,
    pub std_dev: f64,
}

Batch Indicator wrapping the regime-internal BollingerBands primitive.

Outputs bb_upper, bb_mid, bb_lower, and bb_width per bar.

Fields

period: usize

std_dev: f64

Implementations

impl BbPrimIndicator

pub fn new(period: usize, std_dev: f64) -> Self

Trait Implementations

impl Clone for BbPrimIndicator

fn clone(&self) -> BbPrimIndicator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BbPrimIndicator

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

Formats the value using the given formatter.

impl Indicator for BbPrimIndicator

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

Short canonical name, e.g. "SMA", "RSI", "MACD".

fn required_len(&self) -> usize

Minimum number of candles required before output is non-NaN. Mirrors Python’s implicit warm-up period used for validation.

fn required_columns(&self) -> &[&'static str]

Which OHLCV fields this indicator reads.

fn calculate( &self, candles: &[Candle], ) -> Result<IndicatorOutput, IndicatorError>

Compute the indicator over a full candle slice (batch mode).

fn check_len(&self, candles: &[Candle]) -> Result<(), IndicatorError>

Validate that enough data was supplied, returning a descriptive error if not.
