Struct FibRetracement 

pub struct FibRetracement { /* private fields */ }

Fibonacci Retracement (FibRetracement).

Tracks confirmed swing pivots with a baked-in 5% reversal threshold (the same non-repainting logic as crate::indicators::ZigZag) and, once two pivots exist, reports the seven retracement levels of the leg between them.

The levels are recomputed each time a new pivot confirms; between confirmations Indicator::update returns the locked levels of the current leg. Before the first leg is complete it returns None.

Parameter-free: the threshold is a compile-time constant, mirroring the chart- and harmonic-pattern detectors, so construction is infallible.

See crates/wickra-core/src/indicators/fib_retracement.rs.

Implementations

impl FibRetracement

pub const fn new() -> Self

Construct a new Fibonacci Retracement tracker.

Trait Implementations

impl Clone for FibRetracement

fn clone(&self) -> FibRetracement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FibRetracement

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

Formats the value using the given formatter.

impl Default for FibRetracement

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for FibRetracement

type Input = Candle

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

type Output = FibRetracementOutput

Type of one output value.

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

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.
