Quote from xDojix:
If you go through the time and sales you can see Friday in the Jan/Feb spread book
31,207 spreads traded with tons of +100 lot trades on the bid in the last hour of the pit session with most of that volume happening in the last 10 minutes. That is against 27,236 trades total in the rest of the day session.
Today the numbers were a little more reasonable but still looking pretty weird. 31.207 trades in the last hour against 50,793 in the rest of the session.
The daily price bars are longer yesterday today and today then I think pretty much any other day in the history of the contract. So the action does stand out to me...
