Struct Triangle 

pub struct Triangle { /* private fields */ }

Triangle — a consolidation pattern bounded by two converging trendlines, detected from the two most recent swing highs and lows.

Built on confirmed swing pivots ([SWING_THRESHOLD] = 5%); evaluated on every bar that confirms a new pivot once four pivots exist:

ascending   : flat highs   + rising lows    → +1 (bullish bias)
descending  : falling highs + flat lows      → -1 (bearish bias)
symmetrical : falling highs + rising lows     → +1 if the last pivot is a low
                                                (an up-bounce), else -1

“Flat” means the two highs (or lows) are within [LEVEL_TOLERANCE] (3%) of each other; “rising”/“falling” means they differ by more than that tolerance. The symmetrical case is directionally neutral, so its sign follows the momentum of the most recently confirmed swing. Output is +1.0 / -1.0 / 0.0; never None.

Implementations

impl Triangle

pub const fn new() -> Self

Construct a new Triangle detector.

Trait Implementations

impl Clone for Triangle

fn clone(&self) -> Triangle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Triangle

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

Formats the value using the given formatter.

impl Default for Triangle

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for Triangle

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.
