Struct StaticProvider 

pub struct StaticProvider { /* private fields */ }

A fixed dataset served as a provider.

Implementations

impl StaticProvider

pub fn new(data: Data) -> Self

pub fn from_csv(path: impl AsRef<Path>) -> Result<Self, DataError>

Serve the bars of a time,open,high,low,close,volume CSV. A header naming the columns is required; # comment lines are ignored. The symbol defaults to a placeholder — set it with with_syminfo.

pub fn with_syminfo(self, syminfo: SymInfo) -> Self

The symbol these bars belong to, exposed to scripts as syminfo.*.

pub fn data(&self) -> &Data

The bars and symbol this provider serves.

Trait Implementations

impl DataProvider for StaticProvider

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.
