I'm always looking to get solid spreads on - involving multiple structures - for as cheap as possible. For me, it's the opposite of selling the nickels 8 SD's out. If I have any options that are short and trading for a nickel - I get rid of them. In fact I'll usually close them out well before the nickel, but only to juice the spread in the case of a bigger move on expiry day. There is nothing left to gain at those levels. It's awesome to be able to occasionally jack one into the parking lot. But if you are batting .150 you aren't going to play in the big leagues. It's about getting on base...singles and doubles.
I was trying to show OP how to be as close to trading naked and not have great amount being held for margin. I do either Debit or Credit spreads but use much closer strikes as I am concentrating on the risk than much of anything else. I can't believe Cubs even signed Heyward all those bucks cause he wasn't worth it even before this season. And Cub's pitcher Lester is very good pitcher-if he learned to throw to first-he's be an outstanding pitcher-can't believe a leftie can't throw to first. Cubs be smart to keep Folwer.
