The experts on Spread trading and seasonal commodity trends and high odds trades etc is Moore Research. I would definitely give them a call and pump their brains for info as they supply all this stuff for a living to large commodity trading firms. I've never seen anyone else come close to what they offer so they should be very helpful when putting a particular spread trading plan together. I've found them very helpful even on the phone with most anything they do and offer. They also produce extensive reports on each commodity. Doesn't cost a dime to check them out and pump their minds for ideas and information. See link:
