Struct KickingByLength 

pub struct KickingByLength { /* private fields */ }

Kicking-by-Length — the Kicking pattern with the signal taken from the longer of the two marubozu rather than from the gap direction. When the two shadowless candles differ in size, the bigger one is treated as the dominant force.

marubozu = |close − open| >= 0.95 * (high − low)
setup: two opposite-coloured marubozu separated by a gap
  black then white gapping UP, or white then black gapping DOWN
signal = colour of the LONGER marubozu  (white -> +1.0, black -> −1.0)

Output is +1.0 or −1.0 when the kicking setup is present and 0.0 otherwise. Note this can disagree with Kicking: a black marubozu kicked up by a shorter white marubozu reports −1.0 here. The first bar always returns 0.0 because the two-bar window is not yet filled. The marubozu threshold follows the geometric house style rather than TA-Lib’s rolling averages. Pattern-shape check only — no trend filter is applied; combine with a trend indicator for actionable signals.

Signed ±1 encoding

This detector emits the uniform candlestick sign convention shared across the pattern family — +1.0 bullish, −1.0 bearish, 0.0 no pattern — so it drops straight into a machine-learning feature matrix as a single dimension.

Example

use wickra_core::{Candle, Indicator, KickingByLength};

let mut indicator = KickingByLength::new();
indicator.update(Candle::new(12.0, 12.0, 10.0, 10.0, 1.0, 0).unwrap());
// White marubozu gaps up and is the longer body -> +1.
let out = indicator
    .update(Candle::new(14.0, 20.0, 14.0, 20.0, 1.0, 1).unwrap());
assert_eq!(out, Some(1.0));

Implementations

impl KickingByLength

pub const fn new() -> Self

Construct a new Kicking-by-Length detector.

Trait Implementations

impl Clone for KickingByLength

fn clone(&self) -> KickingByLength

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KickingByLength

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

Formats the value using the given formatter.

impl Default for KickingByLength

fn default() -> KickingByLength

Returns the “default value” for a type.

impl Indicator for KickingByLength

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.
