You have to be able to look at the trade frequency of any commodity that you choose and you have to plan strategies way before hand to look for potential trading setups so that your options are open when you start to speculate in the market. Having a good strategy and knowledge of aspects like market frequency and psychology will help you have more and more trades (increased volume of trading) within a single day, sometimes over several markets, which means you can have a higher potential of making more profits. Don't believe the hype that you can make tremendous amounts of money in day trading and start pumping in huge amounts of money on speculative commodities like futures or even the more dangerous Forex.
