• What were the primary drivers of the dramatic increase in "Vol-of-Vol" we saw at the end of 2014?
• CBOE is launching VIX weeklies soon. Does he feel they have the potential to succeed where VXST has failed miserably?

Volatility Voicemail: Listener questions and comments

• Question from Mark Brant: Please address how IV chain structure can make a spread more viable or less viable and how liquidity affects such IV structures.
• Question from AdamVega:Hello I am a big fan, thank you for your great shows. I have been looking for a platform that I use for Backtesting. I currently use thinkorswim but Backtesting is slow and not reliable. Any suggestions? Thanks AdamVega
