the SVXY BWB (big wide butterfly) above can prolly be had for cheaper if you wait til we get a bit of vix crash....also, you don't have to hold till expiry as there may be good returns in the spread well before then - I have shown the P/L in April, ~2 months b4 expiry....in fact, this is the better way to trade these flys - with plenty time to work.....
