Struct ThreeSoldiersOrCrows 

pub struct ThreeSoldiersOrCrows { /* private fields */ }

Three White Soldiers / Three Black Crows — a 3-bar continuation pattern of three consecutive long candles in the same direction, each opening inside the previous body and closing beyond it.

Three White Soldiers (+1.0):

all three green & monotonically rising closes
  & each open in [prev.open, prev.close]
  & each close > prev.close

Three Black Crows (−1.0): the mirror — three red candles with monotonically falling closes.

Pattern-shape check only — no trend filter is applied; combine with a trend indicator for actionable signals.

Example

use wickra_core::{Candle, Indicator, ThreeSoldiersOrCrows};

let mut indicator = ThreeSoldiersOrCrows::new();
indicator.update(Candle::new(10.0, 11.5, 9.9, 11.0, 1.0, 0).unwrap());
indicator.update(Candle::new(10.5, 12.5, 10.4, 12.0, 1.0, 1).unwrap());
let out = indicator
    .update(Candle::new(11.5, 13.5, 11.4, 13.0, 1.0, 2).unwrap());
assert_eq!(out, Some(1.0));

Implementations

impl ThreeSoldiersOrCrows

pub const fn new() -> Self

Construct a new Three White Soldiers / Black Crows detector.

Trait Implementations

impl Clone for ThreeSoldiersOrCrows

fn clone(&self) -> ThreeSoldiersOrCrows

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreeSoldiersOrCrows

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

Formats the value using the given formatter.

impl Default for ThreeSoldiersOrCrows

fn default() -> ThreeSoldiersOrCrows

Returns the “default value” for a type.

impl Indicator for ThreeSoldiersOrCrows

type Input = Candle

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

type Output = f64

Type of one output value.

fn update(&mut self, candle: Candle) -> Option<f64>

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.
