We talk about theory a great deal here, but we never seem to discuss mechanics of entering our spreads/combos. When I started out trading naked puts in 2004 ( i know how lucky I was until August 2007 hit), I would enter all of my intended short put trades on the Friday of expiration week for the next month or on the following Monday, not caring if the underlying was dipping or continuing its upward trend. Then, after a while, I began to only enter these trades when the market was down at the close (4:00 to 4:15pm). {BTW, who is trading from 4-4:15 anyway? MM's, institutions, hedge funds?} Now, my thinking is: only enter bull put spreads/bear call spreads when the market is down/up, and I now stagger my entries instead of entering them all at once. I do the same for my IC's now. I enter my short straddles and my Iron butterflies in a staggered fashion based on underlying changes. Anyone care to comment on their mechancs of entering trades? Lastly, how do you determine your strikes (bodies and wings)? Do you decide by using resistance and support levels? Do you decided based on amount of credit received? I have used both as well as gut (OTM or deep OTM).
