It's called OptionVue. I use it as well, but can sometimes be a bit buggy (long load times, server issues). I have a one year license, but not sure if I keep it thereafter. @ Longshot520: I'm wondering how this strategy worked for you during the Oct-Jan bull market. It should perform well in a range-bound or slightly bearish market, but not one I would like to use in a bull market (difficult to adjust). Your hedge on the call side helps a lot though.
