Struct Cypher 

pub struct Cypher { /* private fields */ }

Cypher — a 5-point (X-A-B-C-D) harmonic pattern whose C leg is measured against XA (not AB) and whose D retraces the XC leg by 0.786:

AB / XA ∈ [0.382, 0.618]
BC / XA ∈ [1.13, 1.414]  (C extends beyond A, measured on XA)
CD / XC ∈ [0.74, 0.83]   (≈ 0.786 retracement of XC — the D completion)

Output is +1.0 (bullish, D a swing low), -1.0 (bearish, D a swing high), or 0.0; never None. See crates/wickra-core/src/indicators/cypher.rs.

Implementations

impl Cypher

pub const fn new() -> Self

Construct a new Cypher detector.

Trait Implementations

impl Clone for Cypher

fn clone(&self) -> Cypher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cypher

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

Formats the value using the given formatter.

impl Default for Cypher

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for Cypher

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.
