Struct EngineIndicator 

pub struct EngineIndicator {
    pub config: IndicatorConfig,
}

Batch Indicator adapter for Indicators.

Replays candles through the full engine (L1–L4, L9–L11) and emits per-bar columns for every published field.

Fields

config: IndicatorConfig

Implementations

impl EngineIndicator

pub fn new(config: IndicatorConfig) -> Self

pub fn with_defaults() -> Self

Trait Implementations

impl Clone for EngineIndicator

fn clone(&self) -> EngineIndicator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EngineIndicator

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

Formats the value using the given formatter.

impl Indicator for EngineIndicator

fn name(&self) -> &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.
