While searching for graphs/charts for commodity prices, I stumbled upon a website that has the display of various technical analysis of the on-going market trend. The corn futures price chart is attached to the link below.

Although I do not understand how most of the types of indicators work, I do get a grasp the general direction of the market from the analysis.

In addition, I particularly like the daily market analysis section of the website http://www.futuresmag.com/. They do have some interesting commentaries supported with charts and details that are clear to understand. Furthermore, the education section has articles on trading. Although most may be irrelevant to the trading game and some can be a little obscure, they do shed some lights on how commodity futures and options work.
