Well, for the life of me I couldn't find out why. Perhaps the vol was to high to begin with, but I've been trading these since inception and I've never seen a vol dump like that. That or someone had their values wrong. Guess we'll find out soon enough. If anyone has anything to add that I might not have thought of please let me know. Thanks
