Haven`t seen that in a while.
No, not illiquid expiring month. I'm talking July crude last week.Quote from BlueStreek:
I grant you if you are talking about the expiring front month on the last day of trading, going from 68 to 64 and back to 68 in very short time.
However, did you check out those bid ask spreads that day, sometimes they were like 50 cents.
That was just major mess with it b/c you can type bs trading.
