10 min before closing 10/20/17

As it often happens on option exp days, just when volume would be expected to increase, Opko option volume often is low.  Calls 1366 and puts 456, both about 80% of depressed 5 day avg volume.

Most trading for both puts and calls has been between bid and ask, indicating little buying or selling pressure.

Hate to be a broken record, but little to learn from option trading today.  Enjoy the weekend.
