Struct StudyData 

Source 
pub struct StudyData<'a> {
    pub request: StudyDataRequest,
    pub bars: &'a [Bar],
    pub clock: BarClock,
    pub instrument: Option<&'a Instrument>,
    pub timeframe: Timeframe,
}
Expand description

A requested series available during calculation, sorted by time with unique bars. Metric points use their value for OHLC and zero volume, without interval aggregation. An unavailable history has no bars; it is never substituted with the chart’s prices.

Fields§

§request: StudyDataRequest

The declaration this series answers, before resolving chart defaults.

§bars: &'a [Bar]

Historical and current bars owned by the chart or the host.

§clock: BarClock

Boundaries of the requested interval in its exchange calendar.

§instrument: Option<&'a Instrument>

Resolved instrument metadata, when available.

§timeframe: Timeframe

Resolved calculation interval.

Implementations§

Source§

impl StudyData<'_>

Source

pub fn bar_at(&self, time: DateTime<Utc>) -> Option<usize>

Index of the bar containing time, retaining missing price intervals as gaps. For metrics, the latest point at or before time, held until the next publication.
