Who bought 4k MSFT puts on expiration day?

You have no clue what you are doing, you better get out before you lose too much...

I can pretty much guarantee that trade is not gonna become profitable.

 

?

 

this guy is out 260k or more so far and he is still in his position

This guy is costing me money in the process of ghosting himself

 

Maybe he sold them higher.

 

Maybe its a closing transaction.

 

open interest went up 4k after

 

how do you get realtime open interest?

 

I didn't, but I suspected from the market reaction it was an opening, and after 15 minutes it showed up on the board

 

I was just hedging my PnL. I leave work early for a round of golf. Don't worry about it.

 

Well that's 180k out the window.
