Today, I was watching Orange Juice on my ThinkorSwim trading platform at the close. It closed at 181.30 on the January contract. I watched the bid/ask spread until the final bell and that was the last trade and it sat like that for a couple of hours on my screen. Later in the afternoon, around 3:30ish or so, I noticed that the last price had been changed to 179.05, a considerable difference.
Can anyone clarify why this happened? For what it is worth I have noticed this several times on different futures as well.
Why is there this discrepancy?
