EOD Greeks

FreeValueStandardPro

Fetch end-of-day Greeks history for an option contract.

• Returns the data for all contracts that share the same provided symbol and expiration.
• Uses Theta Data's EOD reports that get generated at 17:15 ET each day. The closing option price and closing underlying price are used for the greeks calculation.
• Set expiration to * if you want to retrieve data for every option that shares the same symbol. (note: Any expiration=* must be requested day by day)

pub fn option_history_greeks_eod(
    &self,
    symbol: &str,
    expiration: &str,
    start_date: &str,
    end_date: &str,
) -> OptionHistoryGreeksEodBuilder<'_>

Optional parameters chain on the builder: .strike(&str), .right(&str), .annual_dividend(f64), .rate_type(&str), .rate_value(f64), .version(&str), .underlyer_use_nbbo(bool), .max_dte(i32), .strike_range(i32). Execute with .await → Result<Vec<GreeksEodTick>, Error>, or decode chunk-by-chunk with .stream(handler).

Example

let rows = tdx
    .option_history_greeks_eod("SPY", "20250321", "20250303", "20250306")
    .strike("570")
    .right("C")
    .await?;
for t in &rows {
    println!("date={} close={} delta={} implied_volatility={}", t.date, t.close, t.delta, t.implied_volatility);
}

ThetaDataDxClient.option_history_greeks_eod(
    symbol, expiration, start_date, end_date,
    *,
    strike=None, right=None, annual_dividend=None, rate_type=None,
    rate_value=None, version=None, underlyer_use_nbbo=None, max_dte=None,
    strike_range=None, timeout_ms=None,
) -> GreeksEodTickList

option_history_greeks_eod_async(...) awaits the same call shape. Chain .to_pandas() / .to_polars() / .to_arrow() / .to_list() on the result.

Example

rows = tdx.option_history_greeks_eod(
    "SPY",
    "20250321",
    "20250303",
    "20250306",
    strike="570",
    right="C",
)
for t in rows:
    print(t.date, t.close, t.delta, t.implied_volatility)

optionHistoryGreeksEOD(
  symbol: string, expiration: string | Date, startDate: string | Date,
  endDate: string | Date, options?: { ... },
): Promise<Array<GreeksEodTick>>

Optional parameters ride in a single trailing options object: strike?: string, right?: string, annualDividend?: number, rateType?: string, rateValue?: number, version?: string, underlyerUseNBBO?: boolean, maxDTE?: number, strikeRange?: number, timeoutMs?: number.

Example

const rows = await tdx.optionHistoryGreeksEOD('SPY', '20250321', '20250303', '20250306', { strike: '570', right: 'C' });
for (const t of rows) {
  console.log(t.date, t.close, t.delta, t.impliedVolatility);
}

std::vector<GreeksEodTick> option_history_greeks_eod(
    const std::string& symbol,
    const std::string& expiration,
    const std::string& start_date,
    const std::string& end_date,
    const EndpointRequestOptions& options = {}) const;

Optional parameters chain on EndpointRequestOptions: .with_strike(...), .with_right(...), .with_annual_dividend(...), .with_rate_type(...), .with_rate_value(...), .with_version(...), .with_underlyer_use_nbbo(...), .with_max_dte(...), .with_strike_range(...). Throws tdx::Error on failure.

Example

auto rows = client.option_history_greeks_eod("SPY", "20250321", "20250303", "20250306",
    tdx::EndpointRequestOptions{}.with_strike("570").with_right("C"));
for (const auto& t : rows) {
    std::cout << t.date << ' ' << t.close << ' ' << t.delta << ' ' << t.implied_volatility << "\n";
}

Wildcard requests additionally populate expiration (YYYYMMDD), strike (dollars), and right ("C" / "P") on every row to identify the contract; on single-contract requests these are absent (None / null / undefined; the Rust and C rows carry the documented 0 / 0.0 / '\0' fills).
