Hi Simon,
I think Trades gave you the best answer.

Where did you find this "A six largest purchase of corn went public today" ???
If an article please post a link. I'm curious just how big it was if was the sixth largest.

Also, I noticed Qindex posted on all of the Major grains today. I do not understand his methods but I am starting to think he might be a "good barometer" to pay attention when he does this. He recently zeroed in on Gold in all major currencies - so we'll see what develops.

Thanks, Lee
