Struct HmmIndicator 

pub struct HmmIndicator {
    pub config: HMMConfig,
}

Batch Indicator adapter for HMMRegimeDetector.

Replays candles through the streaming HMM detector and emits per-bar hmm_conf (0–1) and hmm_regime_id:

• 0 = Uncertain
• 1 = MeanReverting
• 2 = Volatile
• 3 = Trending(Bullish)
• 4 = Trending(Bearish)

Fields

config: HMMConfig

Implementations

impl HmmIndicator

pub fn new(config: HMMConfig) -> Self

pub fn with_defaults() -> Self

Trait Implementations

impl Clone for HmmIndicator

fn clone(&self) -> HmmIndicator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HmmIndicator

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

Formats the value using the given formatter.

impl Indicator for HmmIndicator

fn required_len(&self) -> usize

Minimum candles before meaningful output.

The HMM requires min_observations returns, which means min_observations + 1 close prices (one extra to form the first return).

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

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

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.
