ONE vol settings vs TOS


New Member
Hi guys and gals,

I've used ONE quite a while ago for a month trial, but my trading at the time didn't really warrant paying for it. Now that I'm getting into the bigger structures, I am considering the service.

Does ONE require flipping back and forth using different vol models or does their "vol surface" handle it pretty well? I didn't know about flipping back and forth between the vol models in TOS, so that was a great little tidbit to add to the course Ron!
