there is not much you can do. Question: was that your first option? where did you learn first about options? did you at least had a crash course about them?

Feb 19, strike 70. When stock was 310, they were $15.5 a couple of days ago, when the stock went a bit down then back to 310 they were $17. They are 23-25 right now.
