Buy when the price starts with a 2. Sell when the price starts with a 4. That's been the deal for 4-5 years now. I'm sure it'll be wrong some day, as everything changes eventually, but it's been pretty good to me.
Or you could do it at 32 and 38. Whatever suits you.
You could also sell jan'14 $30 puts for 2.05, that's 7% for agreeing to buy it cheap 10 months from now.
I don't mean to make light of your frustration, I've been-there-and-done-that more than a few times.
