All option purchases are effectively ‘long’. Not true, you can write puts and calls, essentially shorting them.
Writing options are different than purchasing an option. This is why I made the distinction on purchasing an option. In the case where you are writing or originating an option, you are effectively on the short side. If you look at where I put in italics on this entry, the originators of the put/call could be said to be having the short position. See sections specifically dealing with Buy a put, Buy a call.
