Forex is one of the things that is becoming increasingly popular among those who want to make a solid amount of money in a year or two. As money has shifted on its own and has been taking care of news and speculation all the time, many people have started to use software that helps in Forex trading.
There are many different online trading platforms that meet different people. Some are made for experts and others are for beginners. It is important, or at least very good, to know the platform (software) you are using before entering the market. As it is not allowed to lose money and lose money, you should first try a demo version of a platform (if available) or view the entire system your friend is using. The best platform to get started from the experience of people I know is Meta Trader 4. Others who started with the platform called VT Trader said it took a long time to come up with all the options, but once they knew how everything was, they had no problem and preferred it to Meta Trader 4.
After all the platform or software you are using, it is not as important as making money. Find the platform that suits you and good luck.
