Quote from Hester:
If you close the entire position before expiration, then you don't get to keep the premium. You have to buy back the call which will cost money. If hold the position through expiration and if spy is at 110.01 or above, your stock will get called away at 110 (thats the price you sell it at) and you get to keep premium. In this case do not worry about doing anything yourself, you do not have to close the position yourself, it happens automatically. If spy is below 110 through expiration you keep premium and your stock is not called away.
Great. Thanks!
