I’m curious how all the buying and selling happens in options. Where does the “free float” if you will comes from? The units that people are buying and selling, where did they originate from?
Say, a new option is created today ABC and I want to buy it. Who will sell it to me (the first buyer)? Who owns it to be able to sell? And how will the price be determined?
I tried searching for it but couldn’t find an answer.
