RE: Expect a good drop tomorrow Looking at the open interst calls and puts, it looks as if the pro's need to let it get to 655 or 660 for the best kill in both calls and puts the way I see it. There's 20 million bucks payout in puts sitting at $660 alone if it stays at today's level, and this will get much higher if the price drops before expiry.
It looks to me that a balance will probably be around a closing price of about $657, but what do I know? (depends on who cashes in there chips before expiry).
