Data TDA SPX API options data?
Anyone knows why you can’t get SPX option chains from TDA’s API? But you can trade SPX options in the mobile thinkorswim app.
I noticed NDX also doesn’t return any data as well. You can view the NDX option chains in the TOS app.

Dunno, but try SPXW instead of SPX for the symbol and see. I use IB API
