Michael, the open interest number is total, not per exchange. But 5700 is still a lot of contracts for one strike/expiry.

BTW, you state that "When around 50% of the float has been shorted, no shares further shares can be borrowed." Is this a NASDAQ rule? I could've sworn that AMZN's short interest last fall, before the lock-up ended, was about 2/3 of the float. I've never heard this rule, but I'm not an active short seller.

Bob?
