I completely agree on the Euro/Dx comments.
Looking at your sugar chart, and at what I get ......
I have a high of about 35.5 around 2/4/11. Not sure if my chart is correct or not at the moment.
I started to look at the Oct. options and there is a fairly high OI on up to about 35 and I noticed your chart has a high of about 28 ???
Beyond the observation, I haven't sorted it out.
