What are advanced/professional volatility trading software packages? By advanced/professional I mean that you can parametrize models for volatility curves/surfaces, see what options are bid over/offered under. Automatic spread hitting and auto-hedger is something I would like to have too. I know Orc but it's way too pricey. I know there's Actant and OptionsCity. Expensive too. What are other options? Is there anything that could be hooked up to Interactive Brokers?
