Struct FibChannel 

pub struct FibChannel { /* private fields */ }

Fibonacci Channel (FibChannel).

From the last three confirmed pivots, the two same-direction outer pivots define a sloped base trendline and the opposite middle pivot sets the channel width (its signed distance from the base line). Parallel lines are then offset by Fibonacci multiples of that width and reported at the current bar.

slope     = (p2 - p0) / (bar2 - bar0)
base(bar) = p0 + slope * (bar - bar0)
width     = p1 - base(bar1)
level(r)  = base(cur) + r * width

Parameter-free; construction is infallible. Returns None until three pivots have confirmed.

Implementations

impl FibChannel

pub const fn new() -> Self

Construct a new Fibonacci Channel tracker.

Trait Implementations

impl Clone for FibChannel

fn clone(&self) -> FibChannel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FibChannel

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

Formats the value using the given formatter.

impl Default for FibChannel

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for FibChannel

type Input = Candle

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

type Output = FibChannelOutput

Type of one output value.

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

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.
