Struct SessionRange 

pub struct SessionRange { /* private fields */ }

Per-session high-low range, keyed off the wall-clock hour of Candle::timestamp.

The local day (after shifting by utc_offset_minutes) is split into three eight-hour sessions: Asia 00:00..08:00, EU 08:00..16:00, US 16:00..24:00. Each session accumulates its own high / low; the reported range is high - low, or 0.0 before that session has seen a bar. All three re-anchor automatically at the day boundary.

Example

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

let hour = 3_600_000;
let mut sr = SessionRange::new(0);
// 02:00 UTC — Asia session.
sr.update(Candle::new(100.0, 104.0, 98.0, 101.0, 1.0, 2 * hour).unwrap());
// 10:00 UTC — EU session.
let v = sr.update(Candle::new(101.0, 110.0, 100.0, 109.0, 1.0, 10 * hour).unwrap()).unwrap();
assert_eq!(v.asia, 6.0);
assert_eq!(v.eu, 10.0);
assert_eq!(v.us, 0.0);

Implementations

impl SessionRange

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

Construct a Session Range indicator with the given UTC offset (minutes).

pub const fn utc_offset_minutes(&self) -> i32

Configured UTC offset in minutes.

pub const fn value(&self) -> Option<SessionRangeOutput>

Most recent output if at least one bar has been seen.

Trait Implementations

impl Clone for SessionRange

fn clone(&self) -> SessionRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionRange

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

Formats the value using the given formatter.

impl Indicator for SessionRange

type Input = Candle

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

type Output = SessionRangeOutput

Type of one output value.

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

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.
