Struct MidPoint 

pub struct MidPoint { /* private fields */ }

Midpoint (MIDPOINT): the average of the highest and lowest value of the input series over the last period points.

MIDPOINT = (highest(value, period) + lowest(value, period)) / 2

Where MidPrice takes the window extremes from a candle’s high/low, MIDPOINT works on a single scalar stream (typically the close), taking the max and min of that stream over the window. The first value is emitted once period points have been seen.

Example

use wickra_core::{Indicator, MidPoint};

let mut indicator = MidPoint::new(5).unwrap();
let mut last = None;
for i in 0..40 {
    last = indicator.update(100.0 + f64::from(i));
}
assert!(last.is_some());

Implementations

impl MidPoint

pub fn new(period: usize) -> Result<Self>

Errors

Returns Error::PeriodZero if period == 0.

pub const fn period(&self) -> usize

Configured period.

Trait Implementations

impl Clone for MidPoint

fn clone(&self) -> MidPoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MidPoint

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

Formats the value using the given formatter.

impl Indicator for MidPoint

type Input = f64

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, value: f64) -> 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.
