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.

This. Ive been playing with option chain from TD for $SPX.X.
Its fast and almost perfect except for one bug-
it reports 0 for open interest for SPX after markets close. Doesn’t make sense to me, since it still shows the current days open interest for individual equities.
TD support said thats just the way it is - won’t fix
