Garbonzo: Do you own the calls in a regular or tax-advantaged account? If the former:
If you find that you can't get your sell order executed at intrinsic (Ie, EPD is at $54.20, and you can't get $4.20 for your Nov $50 calls), you can guarantee yourself that $4.20/sh by shorting EPD at the price you want (limit order @ $54.20, 100sh per 1 contract) and then calling your broker and exercising your call contracts after the short has gone through.
Only caveats: it requires a regular account as you can't short a stock within a tax-advantaged account, and it also assumes you are dealing with a "shortable" stock. Ie, EPD is classified as "hard to borrow" so depending on the quantity of stock you are dealing with, you may have to break your order up into smaller pieces to be able to short. In some situations there may not be any shares available for shorting. But it can't hurt to try if you are finding you can't get intrinsic for your Calls.
Thanks for the input - I'm a simple man in a complicated world. I just sold the whole lot for $4.10 and made a small profit. Life is a continual learning process and I plan on dying one smart son of a #$%$.
