Struct NewHighsNewLows 

pub struct NewHighsNewLows { /* private fields */ }

New Highs − New Lows — the number of symbols printing a new period high minus the number printing a new period low across a universe.

On each CrossSection tick the value is new_highs - new_lows, read from the per-symbol new_high / new_low flags. A persistently positive reading means fresh leadership is broad (many names making new highs); a negative reading during an index advance is a classic breadth divergence warning that the rally is narrowing.

Input = CrossSection, Output = f64, warmup_period == 1.

Example

use wickra_core::{CrossSection, Indicator, Member, NewHighsNewLows};

let mut nhnl = NewHighsNewLows::new();
// 2 new highs, 1 new low -> net +1.
let tick = CrossSection::new(
    vec![
        Member::new(1.0, 10.0, true, false),
        Member::new(1.0, 10.0, true, false),
        Member::new(-1.0, 10.0, false, true),
    ],
    0,
)
.unwrap();
assert_eq!(nhnl.update(tick), Some(1.0));

Implementations

impl NewHighsNewLows

pub const fn new() -> Self

Construct a new New Highs − New Lows indicator.

Trait Implementations

impl Clone for NewHighsNewLows

fn clone(&self) -> NewHighsNewLows

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NewHighsNewLows

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

Formats the value using the given formatter.

impl Default for NewHighsNewLows

fn default() -> NewHighsNewLows

Returns the “default value” for a type.

impl Indicator for NewHighsNewLows

type Input = CrossSection

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, section: CrossSection) -> 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.
