If you are a beginner looking to get started in forex, one of your greatest tools is the demo account. A demo account is a limited account at a broker that comes with fake money you can use to trade. You can think of it as a free trial of forex trading. Demo accounts serve two purposes: they give you a chance to practice and they let you learn about brokers.
Every broker and trading platform is different. They all take some time getting used to, they offer different trades, they place their buttons and menus in different places, and so on. You need a platform that feels natural and comfortable to you so that you can trade quickly when the time comes. That is why demo accounts are so good: you get the chance to see the interface and use it before investing real money.
Aside from the platform, you also can spend the time experimenting with strategies and trades. Your first trades are not likely to be big winners, but you can prepare yourself and test out your ideas in demo accounts. This will give you an edge over other beginners and get you on a great start.
