Looking for as close to 13.00 as possible. I expect 12.80. Sold the 12 straddle plus a vertical call spread (+12 -13).
Ouch I got 0.55 for the straddle, so I'm out 12.45 - 12.36 = 0.09 there (size 10 = -$90). I paid 0.80 for the +12/-13 spread so I'm out 0.64 - 0.36 + 0.80= there (size 5 = -$540). Net -$630. That call spread was a little dicey considering the max profit was 0.20. This is the first time I lost money with this trade. Definitely not the last.
Actually I liked your trade even if it didn't work out. The short straddle felt like the right trade yesterday.
