Quote from MushinSeeker:
How is this for getting too fancy. Being that you already own the ATM straddle and will get rid of it by day's end, BUt stock goes away from it early but not a lot which means ur sitting on a little profit, but it is still early in the day, would you sell something in the back months-a vertical perhaps to move your delta back to flat?
I don't think that back month vertical will help you since you are closing it out that day. Even if you get close to the mid price you are still paying for bid ask on two options. Plus that vertical will have a lot less gamma than your straddle since it is in the back month. What I have found is that the easiest thing to do is start pulling your calls/puts off to get back to delta neutral taking in profits as you go (or just take the whole thing off once you get to your expected move). I traded this on AAPL last year. I found once it hit a strike it would actually decouple instead of pinning like a lot of people thought it would. I think a big part of it is that everyone is so enamored with selling weeklies you get a slight edge buying (sometimes).
