Struct BodySizePct 

pub struct BodySizePct { /* private fields */ }

Body Size Percent — the absolute body as a fraction of the bar’s range.

BodySizePct = |close − open| / (high − low)

The result lives in [0, 1]: 1 is a full-bodied marubozu (the bar opened at one extreme and closed at the other, no wicks), 0 a doji (open equals close, the bar is all wick). It is the unsigned magnitude companion to BalanceOfPower — where BoP keeps the direction, this keeps only the conviction, which is exactly what candlestick body / range filters key on. A zero-range bar carries no information and yields 0.

This is a stateless per-bar transform: every candle produces one value.

Example

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

let mut indicator = BodySizePct::new();
// body |12 - 10| = 2, range 14 - 10 = 4 -> 0.5.
let c = Candle::new(10.0, 14.0, 10.0, 12.0, 10.0, 0).unwrap();
assert!((indicator.update(c).unwrap() - 0.5).abs() < 1e-12);

Implementations

impl BodySizePct

pub const fn new() -> Self

Construct a new Body Size Percent transform.

Trait Implementations

impl Clone for BodySizePct

fn clone(&self) -> BodySizePct

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BodySizePct

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

Formats the value using the given formatter.

impl Default for BodySizePct

fn default() -> BodySizePct

Returns the “default value” for a type.

impl Indicator for BodySizePct

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.
