A month out. I'm interested in using further OTM VIX options, using them as temporary volatility hedges in the short term and cashing them in if the market moves violently against my position, or holding them if they go down in value and start losing money, until they become profitable again. I'm fine with the lag. It comes with the territory. I'm more concerned about liquidity and getting filled quickly should I need to close out the position fast. BTW I'm still using a demo, not playing with real money yet until I've polished my strategy and it's ready to roll live.
Those AUG options are NOT volatility hedges. In fact, as the OP pointed out, they could actually go DOWN in value with a rise in the vol on the short end (backwardation). Hell, if we got a pop in the VIX in front, I would likely be a huge seller of Aug vol.
