Struct FibExtension 

pub struct FibExtension { /* private fields */ }

Fibonacci Extension (FibExtension).

Tracks confirmed swing pivots with a baked-in 5% reversal threshold and, once two pivots exist, projects the leg between them to the canonical extension ratios — the price targets a continuation of the move would reach.

Parameter-free; construction is infallible. Returns None until the first leg is complete.

Implementations

impl FibExtension

pub const fn new() -> Self

Construct a new Fibonacci Extension tracker.

Trait Implementations

impl Clone for FibExtension

fn clone(&self) -> FibExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FibExtension

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

Formats the value using the given formatter.

impl Default for FibExtension

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for FibExtension

type Input = Candle

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

type Output = FibExtensionOutput

Type of one output value.

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

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.
