Please do not get angry but if you are asking an anonymous message board where dogs, cats, and rats can post for advice and explanation on how to trade sugar, save yourself a lot of money by paper trading first (i.e., fake trading) following YOUR thinking. If you rely on others, you will end up broke very fast.
Like cotton, sugar is very unpredictable now making few Ks moves daily. As a new "investor, can you stomach such moves? What if after you make your trade, you are down 2K in a matter of hours?
By the way, there is no such a thing as investing in commodities. It's all speculation, i.e., we are assuming risk from hedgers and make or loose money due to price fluctuations. So should you call yourself Sugar Speculator ?
