I use Contract-For-Difference (CFD) derivatives through a variety of brokers. Mainly British ones. Each broker has their own policy on configuration of contracts which make some more profitable than others but I usually find higher profit contracts the overall risk is greater. Lower risk contracts tend to have greater brokers fees and spreads. Swings and roundabouts. Have a shop around the CFD market and just try a few out as most will give you a small demo account to test run.
