Struct PercentAboveMa 

pub struct PercentAboveMa { /* private fields */ }

Percent Above Moving Average — the percentage of symbols in a universe that are trading above their reference moving average.

On each CrossSection tick the value is 100 * above_ma_count / universe size, read from the per-symbol above_ma flag (the caller decides which MA — 50-day, 200-day — when it builds the tick). It is a bounded 0..=100 breadth gauge: readings near 100 mean almost the whole universe is in an uptrend (broad participation, but also a potential overbought extreme), readings near zero mark washouts. Crosses of the 50 line are read as bull/bear regime flips.

Input = CrossSection, Output = f64 (a percentage in 0..=100), warmup_period == 1. The universe is non-empty by construction, so the share is always defined.

Example

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

let mut pct = PercentAboveMa::new();
// 3 of 4 symbols above their MA -> 75%.
let tick = CrossSection::new(
    vec![
        Member::with_signals(1.0, 10.0, false, false, true, false),
        Member::with_signals(1.0, 10.0, false, false, true, false),
        Member::with_signals(-1.0, 10.0, false, false, true, false),
        Member::with_signals(-1.0, 10.0, false, false, false, false),
    ],
    0,
)
.unwrap();
assert_eq!(pct.update(tick), Some(75.0));

Implementations

impl PercentAboveMa

pub const fn new() -> Self

Construct a new Percent Above Moving Average indicator.

Trait Implementations

impl Clone for PercentAboveMa

fn clone(&self) -> PercentAboveMa

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PercentAboveMa

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

Formats the value using the given formatter.

impl Default for PercentAboveMa

fn default() -> PercentAboveMa

Returns the “default value” for a type.

impl Indicator for PercentAboveMa

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.
