Interesting. How long have you been doing this? One would imagine that a strategy where you sell the wings that far out would be super-leveraged to the level of implieds and you should see some pretty nasty losses every once in a while. I don't see how setting a stoploss would help, as you could wake up in the morning and see implieds go up 50%.Quote from Betapeg:
My biggest draw down did not exceed 2% of my total capital. The usual draw down is about 0.8-1.5%. I usually sell for about $1,000 of premium. Using my double premium loss stop rule, I buy back if the option rises to $2,000. So my loss is usually just the amount of premium I received. So I give back the premium I received and pay out the same amount as my loss. In this way, I cut my losses short, free up my margin, and enter into the next trade. The key here is to NEVER let a loss run because they can keep on running and running until you're bankrupt (theoretically no limit to how high the price can go).
It does not mean that there is no alpha in these trades, just means that you are getting paid for vol convexity. I know a few people that run similar strategies, but they sell much closer to the money (10-20 delta) and they do see some pretty serious drawdowns.
