A forex demo account is one of the best features of trading forex online. A demo account is a trading package that allows you to trade the market with real quotes in real time, but with virtual funds. In other words, you experience the risks, and test your ability to endure and overcome them, and lose nothing in the process, except perhaps a little bit of your ego, which is only great because that is actually a sobering experience for anyone who has a serious interest in trading.
