Struct YahooSource 

pub struct YahooSource { /* private fields */ }

Yahoo Finance’s chart endpoint (the one yfinance uses) as a DataProvider for equities, ETFs, indices, FX and crypto: it fetches whatever symbol and timeframe are asked for.

Yahoo limits how far back the finer intervals reach — minute data only goes back days — so a range it will not serve comes back empty. Widen it with range.

let data = YahooSource::new().range("6mo").request("AAPL", "1D".parse()?)?;

Implementations

impl YahooSource

pub fn new() -> Self

pub fn range(self, range: &str) -> Self

How far back to fetch: "1d", "5d", "1mo", "1y", "max", …

Trait Implementations

impl Clone for YahooSource

fn clone(&self) -> YahooSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataProvider for YahooSource

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 YahooSource

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

Formats the value using the given formatter.

impl Default for YahooSource

fn default() -> Self

Returns the “default value” for a type.
