    Hi Everyone,

    which firms provide an API to trade for Options?

    (also if someone could provide rough execution/clearing costs)

  3. The obvious choice is interactive brokers.
    Decent API connection, 70 cents per contract (1$ minimum) a little less if you trade larger lots and enough of them

    OptionsXPress is another choice (web service api i think), not sure about their commission structure.
  4. All ET threads eventually mention IB... It's the ET equivalent of Godwin's law.
  5. Not to praise their features but I have a thinkorswim and a IB account.
    I love TOS (support and platform) but I also love IB for their API and their commission structure. I'd be in a world of hurt if either broker decides to terminate my account
