Struct Wedge 

pub struct Wedge { /* private fields */ }

Wedge — a pattern where both trendlines slope the same way but converge, signalling exhaustion of the prevailing move.

Built on confirmed swing pivots ([SWING_THRESHOLD] = 5%); evaluated from the last two swing highs and lows:

rising wedge  : highs rising  AND lows rising,  lows rising faster  → -1 (bearish)
falling wedge : highs falling AND lows falling, highs falling faster → +1 (bullish)

Convergence is the key: in a rising wedge the lower trendline climbs faster than the upper (the range narrows from below); in a falling wedge the upper trendline drops faster than the lower. Output is +1.0 / -1.0 / 0.0; never None.

Implementations

impl Wedge

pub const fn new() -> Self

Construct a new Wedge detector.

Trait Implementations

impl Clone for Wedge

fn clone(&self) -> Wedge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Wedge

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

Formats the value using the given formatter.

impl Default for Wedge

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for Wedge

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.
