Nitro,
I'm afraid in the real world, it's just not that easy. There is no effective way to hedge soft deltas. Certainly not a 5 or 10 delta spread. Just not possible.
Let's go through some scenarios. You are short the 10 delta put spread for a .30 credit. Waaaay OTM. Market starts to tank. What do you do? OK, you suggest to sell some ES futures so that you can work your way out of the spread. So you propose selling the ES futures on the lows in a mean reverting market? OK, so you do that and you have about a 2 handle cushion here assuming you sell small enough to just cover your risk. Now the market squeezes the shit out of every short in the world (including you)! That little .30 credit went up in smoke on the first handle against you, now the ES is up 10 handles from you got short. You have now lost much more money then you would have lost by just taking the spread off.
OK, so you quickly cover your short ES thinking the market has stabilized and you are safe. Uh oh, all the shorties are out, market is now reversing and heading lower! Your short put spread is under attack again!!!!
So you quickly sell some more ES futures. Spreads are still too wide to get out of your put spread. But now the ES is squeezing yet again. What do you do? Of course you buy them back for another 5 handle loss. And the process keeps repeating itself until your broke. See that is the problem. You have such a small credit that there is not enough money there to compensate your losses in the underlying. That's the problem of hedging soft deltas with the underlying. Your best bet 99 times out of a 100 is usually to just swallow your pride and buy back the put spread at a loss.
This is certainly my experience. I would add that commish and slippage really eat up the juice, at least for retail.
Mav, what do you consider a realistic credit for something like a vertical? And how much would you give back before ditching it?
