I'm new to options and am still trying to understand the mechanics. I find options exciting but obviously it's no free lunch...seems like the hardest market to trade after forex. My question is regarding long calendar spreads...where you sell calls at strike A for the say MARCH and buy calls at strike A for APRIL. There's a debit to establish the position. How do I exit? at the expiration of the front-end month...do I have to simulataneously close the back month too? What If I don't close the position by the front-end's expiration...they will expire...but I still had got credit for selling them earlier right? Thanx.
