impl Adl

pub fn new() -> Self

Trait Implementations

impl Clone for Adl

fn clone(&self) -> Adl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Adl

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

Formats the value using the given formatter.

impl Default for Adl

fn default() -> Adl

Returns the “default value” for a type.

impl Indicator for Adl

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

Ports mfv.cumsum() where mfv = mfm * volume and mfm = ((close - low) - (high - close)) / (high - low).

When high == low the multiplier is clamped to 0 (matching the Python mfm[high == low] = 0 mask), so no divide-by-zero can occur.

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

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