Quote from riskfreetrading:
Who the f* you are to ask me question in a non polite way in the first place, and to assume any f*ing thing.
Now back to business. There are multiple reasons when you should CC rather than write a put. I will give you one and I will ask you to provide the other reasons if you are qualified to ask the question inf the first place. If you can not come up with the other reasons, you should ask politely or shut up in the future.
Now one of the reasons (do not stop rolling the drum) is if strike is deep enough in the money (deep for the put), carry is positive, and put is american style. In case you do not know why, the put will be assigned on you.
Now tell me what the other situations are? If you cannot you are a beginner and next time do not ask any f*ing question without being polite. Is it understood? And no one should be making any f*ing assumption, unless sure to be right.
