Struct MacdExt 

pub struct MacdExt { /* private fields */ }

MACD Extended (MACDEXT): MACD with an independently selectable MaType for each of the fast, slow and signal lines.

Classic MacdIndicator hard-wires the exponential moving average everywhere; MACDEXT lets each line use any period-only moving average. The MACD line is fast_ma(price) − slow_ma(price), the signal line is signal_ma(macd), and the histogram is macd − signal. The first full MacdOutput is emitted once the slow and signal averages are both warm.

Example

use wickra_core::{Indicator, MacdExt, MaType};

let mut indicator =
    MacdExt::new(12, MaType::Ema, 26, MaType::Ema, 9, MaType::Sma).unwrap();
let mut last = None;
for i in 0..120 {
    last = indicator.update(100.0 + f64::from(i));
}
assert!(last.is_some());

Implementations

impl MacdExt

pub fn new( fast: usize, fast_type: MaType, slow: usize, slow_type: MaType, signal: usize, signal_type: MaType, ) -> Result<Self>

Construct a MACDEXT with per-line periods and moving-average types.

Errors

Returns Error::PeriodZero if any period is zero and Error::InvalidPeriod if fast >= slow, propagating any moving-average construction error.

Trait Implementations

impl Clone for MacdExt

fn clone(&self) -> MacdExt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MacdExt

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

Formats the value using the given formatter.

impl Indicator for MacdExt

type Input = f64

Type of one input data point (typically f64 for a price, or Candle / Tick).

type Output = MacdOutput

Type of one output value.

fn update(&mut self, value: f64) -> Option<MacdOutput>

Feed one new data point into the indicator and return the freshly computed output, or None if the indicator is still warming up.

fn reset(&mut self)

Reset all internal state, leaving the indicator equivalent to a freshly constructed instance with the same parameters.

fn warmup_period(&self) -> usize

Number of inputs required before the first non-None output can be produced.

fn is_ready(&self) -> bool

Whether the indicator has emitted at least one value since the last reset.

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

Stable, human-readable indicator name. Used by chaining and diagnostics.
