Here is some suggestion on when and what to trade from my own experiences.

Trading Futures, Options on Futures, Commodities, Stocks, Options on Stocks and retail off-exchange foreign currency transactions involves substantial risk of loss and is not suitable for all investors. You should carefully consider whether trading is suitable for you in light of your circumstances, knowledge, and financial resources. You may lose all or more of your initial investment.
