I have watched for the last 5 minutes the funniest game of chicken in a long time. Asking was holding steady at 18.35, and bidding was at 18.25. Bidding went up to 18.26.. one minute, 18.27 one minute, then back to 18.26 (still no trades), then back to 18.25 (Ask at 18.35).... But then ask moved down to 18.34. And bid went up to 18.26 one minute, and then 18.27. Finally, with ask at 18.34, a trade occurs at 18.28. funny... I mean, small differences, but funny to watch none the less.
