pub struct IntradayVolatilityProfile { /* private fields */ }Expand description
Return volatility bucketed by local time of day.
The local day (the wall-clock day of Candle::timestamp
shifted by utc_offset_minutes) is split into buckets equal slices. Each
bar’s simple return close / previous_close - 1 updates the per-bucket
running variance (Welford), and the profile reports the per-bucket sample
standard deviation. The first bar produces no output.
§Example
use wickra_core::{Candle, Indicator, IntradayVolatilityProfile};
let hour = 3_600_000;
let mut prof = IntradayVolatilityProfile::new(24, 0).unwrap();
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, hour).unwrap()).unwrap();
assert_eq!(out.bins.len(), 24);Implementations§

impl IntradayVolatilityProfile
Sourcepub fn new(buckets: usize, utc_offset_minutes: i32) -> Result<Self>
pub fn new(buckets: usize, utc_offset_minutes: i32) -> Result<Self>
Construct an Intraday Volatility Profile with buckets intraday slices.
§Errors
Returns Error::PeriodZero if buckets == 0.
Sourcepub fn value(&self) -> Option<&IntradayVolatilityProfileOutput>
pub fn value(&self) -> Option<&IntradayVolatilityProfileOutput>
Most recent profile if at least one return has been recorded.
