I have invited a local futures broker in my area to write an article for this blog. He is primarily a grains broker and specializes in spreads, the seasonal aspects of agricultural commodities, and the relationships between contract months. This is a subject about which I confess complete ignorance. He may also be able to provide valuable services to part-term or even passive traders who would like to take advantage of the profit potential of the commodities markets, but who don't have the time necessary to do the necessary research. He also has good ethics and I trust him. He is not a pushy sales type. I hope that he will post here to this site sometime soon.
