Hi- I am new to the forum, so please excuse me if this has already been discussed. I am interested in reviewing historical IV skew data and analyzing present IV skew on RUT and SPX. Jim Riggio seems to like LiveVol a lot and I really like their IV charts and the flexibility they offer. However, Live Vol is kind of expensive. Lightspeed is currently offering LiveVol X for free if you have an account with them. They are introducing brokers to Interactive if you want to use LiveVol. I think LiveVol X is as much as 500$/month for a direct platform subscription. https://www.lightspeed.com/platform-comparison/ Has any of you tried to open an account with lightspeed and gotten free access to LiveVol X? Any issues with this approach? Anything else you use to analyze skew? I have TOS, TWS, OptionVue but they seem to be limited in functionalities. Thanks.
