If you're asking yourself why I'm selling at these particular strikes, it is to sell call against at a delta that is correspondent with existing legs' short put delta (e.g., the 4110, -23 delta short call strike was selected to sell against my 3770 +24 delta short put; the 4130, -20 delta short call against my 3740, +21 delta short put, etc.). When I finished doing this, I also figured I could afford to resolve having the extra short call unit on by just closing one of the extra short calls that was currently in profit. This leaves me slightly net delta long in the position.
