Struct CloseVsOpen 

pub struct CloseVsOpen { /* private fields */ }

Close vs Open — the bar’s body as a signed fraction of its open price.

CloseVsOpen = (close − open) / open

A scale-free, signed measure of how far price travelled from open to close: +0.02 is a bar that closed 2% above its open (a green bar), −0.02 the mirror. Unlike BalanceOfPower — which normalises the body by the bar range — this normalises by the open price, so it is directly comparable to a return and stays meaningful across instruments of different nominal price. A zero open carries no scale and yields 0.

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

Example

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

let mut indicator = CloseVsOpen::new();
// open 100, close 102 -> +0.02.
let c = Candle::new(100.0, 103.0, 99.0, 102.0, 10.0, 0).unwrap();
assert!((indicator.update(c).unwrap() - 0.02).abs() < 1e-12);

Implementations

impl CloseVsOpen

pub const fn new() -> Self

Construct a new Close vs Open transform.

Trait Implementations

impl Clone for CloseVsOpen

fn clone(&self) -> CloseVsOpen

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CloseVsOpen

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

Formats the value using the given formatter.

impl Default for CloseVsOpen

fn default() -> CloseVsOpen

Returns the “default value” for a type.

impl Indicator for CloseVsOpen

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.
