• Question from Scott Somer -VolView The $VIX Apr 29-35 call spread is going for about 40 cents, are you more willing to buy or sell it to open? Comment from Oscar Stanko:Hi Mark. I am an avid listener to your options podcasts and wanted to sincerely thank you for your time and energy you've put into creating this valuable (and often humorous) content!
• Question from BigBlanc -I'm liking the VXX erosion play. Question though - Why does everyone talk puts on this trade? Why not selling calls or call spreads? Or maybe the combo - buying puts and selling calls or call spreads? Any back tests on that?
