Gambling?

I have to write a research paper in English and my subject is gambling. My Annotated Bibliography is finished, but I need help with my Contrast / Compare paper. Can anyone help?

So are you comparing and contrasting the casino games with foreign exchange (currency foreign) trading days? Or compare and contrast two casino games like roulette and craps? I would be comfortable writing it, but my sources tell me is research and give meaning to my content.
