    Automatic exercise is only for expiring options, not for further out options.

    If you read what he wrote,both puts ended up being in the money..Trader was asleep at the wheel....

    What I am not sure of is if there is,Auto exercise if an OTM expiring option goes ITM after hours,before 5:30...FWIW, institutions,get a longer look(accordi g to my broker)

  4. You get an extra hour to OCC deadline (IIRC), I could check with my prime on Monday. It's not like the institutions never fuck up exercise instructions, e.g. BAML lost some serious 8-digits a few years ago on an early exercise arbitrage trade (yup, "awesome").

    PS. this is why I have been historically reluctant to play with single name options, despite all the opportunities

    I did a study on closing all my nickel options vs losing $10/share on a Friday gap. The break even was like every 10 months for an event to happen. I’ve experienced a total of 3 in 13 years.

    Were you trading firm capital??

    I find that under portfolio margin,if you dont manage your pennies,the margin explodes on you and instead of looking to put shit on that makes real money, you are left scrambling to get under margin...

    Not too mention the nastygram I get from my broker...

  9. His long puts were OTM at expiration, so no auto-exercise. Then the stock went down in after hours session. The owner of his short puts (the short leg of his spread) was on the ball and exercised during AH. The guy could have exercised his puts (the long leg of his spread), but he wasn't watching the stock AH, apparently. He only got notice of the short put assignment like at 6:30 or something, so it was too late to take action.

  10. As far as I know, auto exercise only happens if the option is one penny or more ITM at official (day session) close. If you want to exercise OTM ops in AH you have to manually do it. This guy's long options were a little bit OTM at official close.
