Need help on how to close an option trade

[atonal777]

Hi, trying to learn a few things, If I were to buy a single call or put, and then sell it a few days later after it realized a profit, could that option be then excersized on me or am i completely out of that contract. I just read this in an article "Selling an options contract to exit a long trade is safe, because the sale is of an already owned contract" Is this true, or being that i sold the option, might i have to come up with 100 shares of that stock.

After the sale, all obligations that you had cease. (you "Bought to open the position" and then you "Sold to close the position")

It cannot be exercised against you.

Thanks, Just out of curiosity, who ultimately is responsible to respond to the exersize?
