Forex is one of those things that is becoming increasingly popular among those who want to make solid money within a year or two. And since changing the money yourself and taking care of the news and speculation all the time can take you a long time people have started using software that helps people in forex trading.
There are many online software trading platforms that match different people, they are made for specialists and others are intended to be used by complete beginners. The important thing or at least a very good thing before going into a forex market is to be familiar with the platform (software) you will use. If you are not allowed to make a mistake and lose money, you should first try a trial version of a platform (if any) or see the complete system your friend is using. From the experience of people I know the best platform to get started, is Meta Trader 4. People love it because of its simplicity of use and the demo platform version available. Others who have started with the platform called VT Trader say it took them a long time to come up with all the options, but once they find that everything has nothing to do with it, they prefer Meta Trader 4.
Since all the platform or software you use is not as important as the money you can make in changing currencies. Find the platform that suits you and good luck.
