Options dead basic question-Should I wait till expiry?

I have traded only Equities till now and now I want to understand Options. They seem to be very complex :frowning: Please explain in layman terms.


Strike Price= 8600

12-08-2016 Close price= 276.7

09-11-2016 Close price= 47.2

Does this mean, If I had Shorted this contract on 12-08-2016 and bought back on 09-11-2016, I would have made a profit of about 80% ? Can I make profits off of premiums alone or should I wait till expiry ?

Thank you.

Got the answer here !
