Struct ThreeDrives 

pub struct ThreeDrives { /* private fields */ }

Three Drives — a symmetric harmonic pattern of two visible drives separated by two retracements, read from the last five pivots X-A-B-C-D (the two drive legs are A→B and C→D):

AB / XA ∈ [1.13, 1.75]   (drive 1 extends the prior retracement)
CD / BC ∈ [1.13, 1.75]   (drive 2 extends symmetrically)
AB ≈ CD (within 20%)      (the two drives are similar in size)
XA ≈ BC (within 30%)      (the two retracements are similar)

Output is +1.0 (bullish, terminal D a swing low — drives down), -1.0 (bearish, drives up), or 0.0; never None. See crates/wickra-core/src/indicators/three_drives.rs.

Implementations

impl ThreeDrives

pub const fn new() -> Self

Construct a new Three Drives detector.

Trait Implementations

impl Clone for ThreeDrives

fn clone(&self) -> ThreeDrives

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreeDrives

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

Formats the value using the given formatter.

impl Default for ThreeDrives

fn default() -> Self

Returns the “default value” for a type.

impl Indicator for ThreeDrives

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.
