The majority of all online brokers in forex offer demo or game account for free so you can preview their platform. It is highly recommend to trade forex under one of these demo accounts before ever trading live so that you can gain experience and confidence in your trading.
After you do begin with your real account it is important to begin using very low leverage. The most important focus of a forex trader should always be being mindful of risk.
As you are learning about forex trading pay attention to the most important part of trading money management. People are often in a rush to get started trading before they are ready, take you time and understand what you are doing before trading.
Since there are no limits on demo trading you can take your time trading under a simulated environment for as long as you like before you open an account with a broker. Trade for at least three months of making consistent profits before making the jump to a live account.
