pub fn new() -> Self

Trait Implementations

impl Clone for KrakenSource

fn clone(&self) -> KrakenSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataProvider for KrakenSource

fn request( &self, symbol: &str, timeframe: Timeframe, ) -> Result<Data, ProviderError>

fn footprint( &self, _ticks_per_row: f64, _va_percent: f64, _imbalance_percent: f64, ) -> Option<Vec<FootprintRow>>

The volume footprint rows for the current bar (request.footprint), lowest price first. None — the default — means the host has no order-flow feed, so the script reads na.

fn financial(&self, _symbol: &str, _id: &str, _period: &str) -> Option<f64>

A fundamental financial metric (request.financial), e.g. id = "TOTAL_REVENUE", period = "FY"/"FQ". None — the default — means the host has no such feed, so the script reads na.

fn dividends(&self, _ticker: &str, _field: &str) -> Option<f64>

A dividend field (request.dividends), e.g. "gross"/"net".

fn earnings(&self, _ticker: &str, _field: &str) -> Option<f64>

An earnings field (request.earnings), e.g. "actual"/"estimate".

fn splits(&self, _ticker: &str, _field: &str) -> Option<f64>

A splits field (request.splits), e.g. "numerator"/"denominator".

fn economic(&self, _country: &str, _field: &str) -> Option<f64>

An economic series (request.economic), e.g. country = "US", field = "GDP".

fn currency_rate(&self, _from: &str, _to: &str) -> Option<f64>

The exchange rate from→to (request.currency_rate). Same-currency pairs are answered as 1.0 by the builtin without consulting the feed.

impl Debug for KrakenSource

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

Formats the value using the given formatter.

impl Default for KrakenSource

fn default() -> KrakenSource

Returns the “default value” for a type.
