I thought option based shorts you could only lose the amount you paid for the options... a put or a call option...
What he has is buying on margin I think... he can potentially lose a lot of money since he has to cover... an option you don't have to cover (I don't think you do)..
Right. You just have to have a margin account Because you can lose more than what you have.
I haven't had enough time to study and learn options as much as I'd like too so at the moment I just am doing regular trades. Though hopefully by December I'll be ready. :D
