Yes, all options do expire, I was referring to the specific example you provided.
An ATM option may or may not be exercised so if you short an ATM option you do not know what your position would be, known as pin risk.
Yes, spot means the price of the underlying futures, stock or whatever it may be.
Pin risk occurs when the underlying expires right at your strike. Iow, you won't know til the next day (broker notifies you) whether you've been assigned since your short option is not itm or otm but it is right atm at expiry.Quote from triggertrader:
what exactly do you mean by "not knowing what your position would be"? dont you know if your option was excercised? does your broker call you and tell you. sorry i am new to this. what happens?
if the option is excercised bascially you lose the premium income you initially collected correct? plus you would take an opposite position in the futures market right?
Quote from MTE:
triggertrader,
Exercise/assignment is not instantenous, so you don't find out about it until the next day, which means that you can face gap risk. I.e. you are assigned based on the settlement price on that day, but you don't find out about the assignment until the next day so you cannot make a trade until the next day and the price may gap against you before you have a chance to unwind the position. So, if you have a clearly ITM option then you can trade the underlying to offset the potential assignment and thus avoid the gap risk, but if the option is ATM then you don't know whether the option will be assigned or not hence you cannot make a "pre-emptive" trade in the underlying to lay off the gap risk.
Whether you keep the premium or not is really irrelevant here. You need to look at your net P/L, but if you like to think of it this way then, yes, you do keep the premium either way, but you then may face a loss on the assignment. It's the same as car insurance. You pay the premium, which the insurance company keeps no matter what happens to your car, but at the same time it may face substantial outflow if you make a claim.
Quote from triggertrader:
i see...so when you say a preemtive trade in the underlying meaning that you would in advance go long the underlying market before the excercise so that the inevitable short position you will take when its excersied will be offset as soon as it is established? (in the case of selling a call)

Each commodity has dramatically different expiration (aka "last trade") dates, and some are entirely confusing (April Crude just closed out, for example).Quote from triggertrader:
speaking of expiration. i have a question.
in reference to futures options where do i find the exact expiration dates for any given commodity? i have looked at the exchange websites but they dont actually tell you. do they all have diffrent expiration dates? do they all expire at the same time?

CME's product calendar is here:
http://www.cme.com/clearing/clr/product_calendar.html
For example, the last trade date for the ES April e-mini option series is 4/20/07. Beware when trading physical commodities (anything that doesn't settle into cash)--expiration of options is generally at an earlier time than the expiration of futures. Keep on the lookout for last trade date, first notice date, and first position date.
