Struct DayOfWeekProfile 

pub struct DayOfWeekProfile { /* private fields */ }

Mean bar return bucketed by local weekday (Monday 0 .. Sunday 6).

Each bar’s simple return close / previous_close - 1 is accumulated into the bucket of its local weekday (the wall-clock day of Candle::timestamp shifted by utc_offset_minutes), and the profile reports the running mean per weekday. The first bar produces no output.

Example

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

let day = 24 * 3_600_000;
let mut prof = DayOfWeekProfile::new(0);
// 1970-01-01 was a Thursday (weekday 3).
assert!(prof.update(Candle::new(100.0, 100.0, 100.0, 100.0, 1.0, 0).unwrap()).is_none());
let out = prof.update(Candle::new(101.0, 101.0, 101.0, 101.0, 1.0, day).unwrap()).unwrap();
assert_eq!(out.bins.len(), 7);

Implementations

impl DayOfWeekProfile

pub const fn new(utc_offset_minutes: i32) -> Self

The offset is a constant and does not follow daylight saving: for a venue that observes it, one value is correct for part of the year and an hour out for the rest, which shifts every session boundary by an hour. Either pass the offset in force for the span being analysed and keep spans that cross a transition apart, or convert the timestamps to the venue’s wall clock upstream and pass 0. Construct a Day-of-Week Profile with the given UTC offset (minutes).

pub const fn utc_offset_minutes(&self) -> i32

Configured UTC offset in minutes.

pub const fn width(&self) -> usize

How many values every emitted profile carries – one bucket per weekday.

Fixed for the lifetime of the indicator, so a caller can size a buffer once instead of guessing.

pub fn value(&self) -> Option<&DayOfWeekProfileOutput>

Most recent profile if at least one return has been recorded.

Trait Implementations

impl Clone for DayOfWeekProfile

fn clone(&self) -> DayOfWeekProfile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DayOfWeekProfile

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

Formats the value using the given formatter.

impl Indicator for DayOfWeekProfile

type Input = Candle

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

type Output = DayOfWeekProfileOutput

Type of one output value.

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

Feed one new data point into the indicator and return the freshly computed output, or None if there is no value for this input.

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.
