I'm looking to roll my OIH Aug 135 short calls to Sep, it's one leg of a calendar spread. OIH is up almost 2% to just below 140. Here are the Greeks given by TOS: Aug: delta: 0.86 gamma: 0.05 theta: [0.16-0.20] Sep: delta: 0.66 gamma: 0.03 theta: 0.10 The Aug is up 1.90 while the Sep is only up 1.50 (i.e. higher delta and gamma). I'm thinking to wait a day or so to let the higher Aug theta do its work. Any other suggestions? Edit: changed puts to calls above.
