Newbie Q: I've never traded futures options--does anyone know a good discount broker which will allow me to trade them within an IRA? I want to buy and hold long-dated crude oil calls (e.g. 2010, 2011). I use TOS for equities options, but they don't offer CL options. Also, I'm finding mixed information on whether margin is required, though it seems like it shouldn't be. And if anyone thinks this is a terrible idea, feel free to let me know that too.
