Are forward curves useful tools for trading decisions and which informations can be gathered from them?
As far as trading is concerned, these forward curves are the price at which you can speculate on the future value of the commodity.  Basically, if you want to speculate on gold, you can either buy the physical and store it somewhere (which may have significant costs) or you can buy futures (ETFs typically hold futures or hold physical and store it for you).  If you buy futures, you will have to roll your position every month, meaning you sell the current month's futures and buy the next month's.  However, these may not be trading at the same price, so each time you roll your position, you face a risk.  If you know you want to hold gold for exactly 1 year, then you can buy a 1-year future, which in this case according to your graph will cost you about $10 more than buying the front month.  The forward curve (or sometimes called the futures term structure) represents the prices at which gold can be bought or sold at various points in the future.
