List available strike prices for an option at a given expiration.

Lists all strikes that are available for an option with a given symbol and expiration date. This endpoint is updated overnight.

pub fn option_list_strikes(&self, symbol: &str, expiration: &str) -> OptionListStrikesBuilder<'_>

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

Example

let rows = tdx.option_list_strikes("SPY", "20250321").await?;
for value in &rows {
    println!("{value}");
}

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

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

Example

rows = tdx.option_list_strikes("SPY", "20250321")
for value in rows:
    print(value)

optionListStrikes(
  symbol: string, expiration: string | Date, options?: { ... },
): Promise<Array<string>>

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

Example

const rows = await tdx.optionListStrikes('SPY', '20250321');
for (const value of rows) {
  console.log(value);
}

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

Throws tdx::Error on failure.

Example

auto rows = client.option_list_strikes("SPY", "20250321");
for (const auto& value : rows) {
    std::cout << value << "\n";
}
