option_list_roots

FreeValueStandardPro

List all available option underlying symbols (roots). Use this to discover which tickers have option chains available in ThetaData.

Code Example

Rust

let symbols: Vec<String> = tdx.option_list_symbols().await?;
println!("{} option roots available", symbols.len());

Python

symbols = tdx.option_list_symbols()
print(f"{len(symbols)} option roots available")

Go

symbols, err := client.OptionListSymbols()
if err != nil {
    log.Fatal(err)
}
fmt.Printf("%d option roots available\n", len(symbols))

C++

auto symbols = client.option_list_symbols();

Parameters

None.

Response

(list)string[]

Underlying ticker symbols with available option chains

Notes

• Returns all underlying symbols, not individual contracts. Use option_list_expirations and option_list_strikes to drill into a specific chain.
• The Rust SDK method is option_list_symbols; "roots" refers to the underlying concept in ThetaData's API.
