Struct FibArcs 

pub struct FibArcs { /* private fields */ }

Fibonacci Arcs (FibArcs).

Three arcs centred on the end of the most recent confirmed swing leg. Time is normalised by the leg’s bar-width so the construction is chart-scale-free: at the leg’s end bar each arc sits exactly on its retracement level, and as time elapses the arc curves back toward the swing-end price, reaching it one leg width later.

u       = (cur - end_bar) / (end_bar - start_bar)
arc(r)  = end + (start - end) * r * sqrt(max(0, 1 - u^2))

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

Implementations

impl FibArcs

pub const fn new() -> Self

Construct a new Fibonacci Arcs tracker.

Trait Implementations

impl Clone for FibArcs

fn clone(&self) -> FibArcs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FibArcs

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

Formats the value using the given formatter.

impl Default for FibArcs

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for FibArcs

type Input = Candle

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

type Output = FibArcsOutput

Type of one output value.

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

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.
