Hello: As a general rule currencies are thought to trend more often than other tradeables. Also there are seasonal trends to grains, cattle, hogs, unleaded & nat gas and crude. These seasonal trends are a good place to start IF you have sufficient knowledge of the market and infrastructure. The graph you asked about was generated by ButtonTrader which is a frontend software product. Based on your post, I would suggest you become an observer rather than a trader. I suggest you observe some of these markets until you have some idea of which one(s) you wish to trade. Take it a step at a time. Steve
