You were answered in post number 2, 7, and 8. I would focus on understanding those. Why post number 6 went into p+l when that was never the topic at hand I have no idea, and the first sentence "It has everything to do with what you paid for the option" is entirely incorrect. See my post #2, I gave you the answer without you ever mentioning anything about premiums, I just eyeballed it, and the answer was obvious. It is the only answer it could be. Premium is meaningless, unless you are figuring out your p+l, which I'll repeat, was never the topic at hand. I'll extend the benefit of the doubt to FSU that he simply misinterpreted your question, which considering your semantics is not much of a leap of faith to make. Your semantics are shit. Not meant as an insult, you are new to this, they are as should be expected, but nonetheless shit. Not going to go down the rabbit hole with this. I'd suggest focusing on your semantics and knowledge of products. You can not exercise short options (see #1, your post #9)
Id have to disagree with you on my response. OP asked "what price would I be short at" The effective price of his shorts is entirely dependent on what price he paid for each option. The amount he paid for each option will determine his basis on the entire position and would have to be known to find the price he is effectively short at. But as you say, maybe I misinterpreted his question.
Semantics. If I own Amazon that I purchased at $6. I am long from $6, but I am currently long at 3,693. At Expry he's short at 960. The importance of communicating like this illustrates itself perfectly on expry, if you are bouncing around strikes, and your boss walks up to you and says, what do you look like here,here,and here. You can immediately look at your net strike position and instantaneously tell what you look like here, here, and here. Otherwise you would need to go look at your statement and calculate your basis crossing each strike, and that's already reflected in your previous p+l anyway.
