More than any other type of speculation, such as forex or stock trading . commodity markets involve a very high degree of seasonality. Hence, it is important that the trader be very aware of the underlying cycles affecting the market in question.

Traders also play the spreads between commodities, which is an extremely popular form of commodity trading. and which effectively multiplies the range of profit opportunities hugely.

Other spread opportunities occur in the price differentials between different delivery months of the same commodities futures contracts. Hence, you might buy the contract nearer to expiration and sell the one further out with the expectation that long-term prices of that commodity will fall with respect to near term prices.

Once you also realize that there are active options contracts in all the major instruments, it becomes clear that commodity trading is a very desirable niche within the universe of speculation.

As with all forms of trading, mental and financial discipline are key factors to success  in commodity trading. Given their extreme volatility, it is paramount that you have a proven method before you ever speculate a single dollar in these often unpredictable markets.

You must also remember that these are real physical products involved, and they can literally be delivered if you fail to close out your position before the expiry of the commodity future or option contract. Otherwise, it can result in a truck pulling up outside your house with your delivery of soybeans, live cattle or cocoa depending on what you have been trading. This has been known to happen!
