Struct DemarkPivots 

pub struct DemarkPivots { /* private fields */ }

DeMark Pivot Points — Tom DeMark’s conditional pivot formulation, derived from a sum X that depends on whether the bar closed up, down or flat.

X = 2·H + L + C   if C  < O   (down bar)
    H + 2·L + C   if C  > O   (up bar)
    H + L + 2·C   if C == O   (doji)

PP = X / 4
R1 = X / 2 − L
S1 = X / 2 − H

Unlike the classic pivots, only one resistance and one support are produced; DeMark’s intent is a tighter, condition-sensitive set rather than a multi-tier fan. The branching means a bar’s open carries information that other pivot variants discard.

Example

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

// Up bar: O=100, H=120, L=80, C=110 -> X = H + 2·L + C = 390.
let up = Candle::new(100.0, 120.0, 80.0, 110.0, 1.0, 0).unwrap();
let lv = DemarkPivots::new().update(up).unwrap();
assert!((lv.pp - 97.5).abs() < 1e-9);

Implementations

impl DemarkPivots

pub const fn new() -> Self

Construct a new DeMark Pivot Points indicator.

Trait Implementations

impl Clone for DemarkPivots

fn clone(&self) -> DemarkPivots

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DemarkPivots

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

Formats the value using the given formatter.

impl Default for DemarkPivots

fn default() -> DemarkPivots

Returns the “default value” for a type.

impl Indicator for DemarkPivots

type Input = Candle

Type of one input data point (typically f64 for a price, or Candle / Tick).

type Output = DemarkPivotsOutput

Type of one output value.

fn update(&mut self, candle: Candle) -> Option<DemarkPivotsOutput>

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.
