Struct Gartley 

pub struct Gartley { /* private fields */ }

Gartley — the classic 5-point (X-A-B-C-D) harmonic pattern, recognised from confirmed swing pivots when the legs fall inside the Gartley Fibonacci windows:

AB / XA ∈ [0.55, 0.70]   (≈ 0.618 retracement of XA)
BC / AB ∈ [0.382, 0.886]
CD / BC ∈ [1.13, 1.618]
AD / XA ∈ [0.74, 0.84]   (≈ 0.786 — the defining D completion)

Output is +1.0 when the terminal point D is a swing low (bullish completion), -1.0 when D is a swing high (bearish), and 0.0 otherwise; never None. See crates/wickra-core/src/indicators/gartley.rs.

Implementations

impl Gartley

pub const fn new() -> Self

Construct a new Gartley detector.

Trait Implementations

impl Clone for Gartley

fn clone(&self) -> Gartley

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Gartley

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

Formats the value using the given formatter.

impl Default for Gartley

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for Gartley

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.
