Struct AdVolumeLine 

pub struct AdVolumeLine { /* private fields */ }

Advance/Decline Volume Line (AD Volume Line) — the running cumulative sum of net advancing volume across a universe.

On each CrossSection tick the net is advancing volume - declining volume, where advancing volume is the total volume of symbols with a positive change and declining volume the total volume of symbols with a negative change. The line accumulates this net over time, so a rising line means volume is flowing into advancing issues (healthy participation) while a falling line warns that declining issues are carrying the volume — the volume-weighted analogue of the plain Advance/Decline Line.

Input = CrossSection, Output = f64, warmup_period == 1 (defined from the first tick).

Example

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

let mut adv = AdVolumeLine::new();
// advancing volume 150, declining volume 50 -> net +100.
let tick = CrossSection::new(
    vec![
        Member::new(1.0, 150.0, false, false),
        Member::new(-1.0, 50.0, false, false),
    ],
    0,
)
.unwrap();
assert_eq!(adv.update(tick), Some(100.0));

Implementations

impl AdVolumeLine

pub const fn new() -> Self

Construct a new Advance/Decline Volume Line indicator.

Trait Implementations

impl Clone for AdVolumeLine

fn clone(&self) -> AdVolumeLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdVolumeLine

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

Formats the value using the given formatter.

impl Default for AdVolumeLine

fn default() -> AdVolumeLine

Returns the “default value” for a type.

impl Indicator for AdVolumeLine

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.
