Grain Marketing Principles
I seen a very good link for marketing prices, principles, and tools. Looks like it is from K-State www.agmanager.info
I like how they assesses the pro's and con's of the various types of tools that can be used in marketing or writing a grain marketing plan.
Here is the link.

The format is done where it appears to have been a power point presentation at one time; I would guess it would have been interesting to watch and see how the interaction went.
