Expirations

FreeValueStandardPro

List available expiration dates for an option underlying.

Lists all dates of expirations that are available for an option with a given symbol. This endpoint is updated overnight.

pub fn option_list_expirations(&self, symbol: &str) -> OptionListExpirationsBuilder<'_>

Execute with .await → Result<Vec<String>, Error>.

Example

let rows = tdx.option_list_expirations("SPY").await?;
for value in &rows {
    println!("{value}");
}

ThetaDataDxClient.option_list_expirations(symbol, *, timeout_ms=None) -> StringList

option_list_expirations_async(...) awaits the same call shape.

Example

rows = tdx.option_list_expirations("SPY")
for value in rows:
    print(value)

optionListExpirations(symbol: string, options?: { ... }): Promise<Array<string>>

Optional parameters ride in a single trailing options object: timeoutMs?: number.

Example

const rows = await tdx.optionListExpirations('SPY');
for (const value of rows) {
  console.log(value);
}

std::vector<std::string> option_list_expirations(
    const std::string& symbol,
    const EndpointRequestOptions& options = {}) const;

Throws tdx::Error on failure.

Example

auto rows = client.option_list_expirations("SPY");
for (const auto& value : rows) {
    std::cout << value << "\n";
}
