A symbol can be defined as a unique identifier for a stock / underlying asset. Common terms also include: root, ticker, and underlying. This endpoint returns all traded symbols for options. This endpoint is updated overnight.

pub fn option_list_symbols(&self) -> OptionListSymbolsBuilder<'_>

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

Example

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

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

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

Example

rows = tdx.option_list_symbols()
for value in rows:
    print(value)

optionListSymbols(options?: { ... }): Promise<Array<string>>

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

Example

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

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

Throws tdx::Error on failure.

Example

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