This program plots every contract of the selected commodity and month. There is no shifting of the contracts. These charts are useful for seeing the effects of carrying charges.

1. Pick a commodity and a month.

2. Select the chart type. The jpegs are faster; the applets are interactive (zooming in is possible and there are data popups).

3. Press "Get Chart". There's a lot of data to download, so be patient.

This is a limited set of commodities available to nonsubscribers. Subscribers can access data for over 40 commodities.
