Farm Futures has a similar service, but you have to choose electronic:

It seems everyone (or at least most) of the free online sources are using the same provider with minor cosmetic changes.

Great pacific trader and agweb also offer similar services.

Could anyone suggest a free service that allows one to modify (draw freehand lines) and save charts?
