Currently I am long the e-minis, with a large calendar spread i put on at the 2400 strike a few weeks ago that is serving me well so far. However this strategy will not serve me well in EXTREME melt downs, I know Taleb and Spitnagel like to buy the tail risk and was even mentioned that they buy the delta .01 or delta .02 front months. However i cant see this being done with out putting on some sort of a back spread to finance those puts. IF i want to replicate something similar to this trade how should i go about doing this? Should my near strike be atm or otm? I would also like some more vega exposure without giving away to much theta. All opinions would be helpful THAK YOU!!
