Quote from SrRuthenate:
Going to rephrase my question to: What's the best way to play this ALLIN with a certain maximum bound risk?. I.e.: I put it on, go to another planet, come back on Sep 20 and my position is intact, no broker liquidations, no exchange excuses, no nothing. I exit when I want after Sep 20th. Those calendars look nice, but aren't bound.
Think like, you are the small stack in a 3way at a poker tournament, get a playable hand and push allin, you are going to get called, but you will not be pushed out of the hand till the river is dealt. At the river, you go home, or you get to play the next hand with 2x or 3x your current stack.
I was referring to an SPY/SPX calendar, not a VIX futures calendar (switch).
