In forex trading, brokers can offer their clients a demo account for foreign trades. A demo account is an account that uses fake currency. This money can be used to conduct virtual trades. You can have a demo account at no charge. 

What's also good about having a demo account is that they show conditions of the real markets. Even though some brokers only allow a month to use this account, there are others that are more generous and allow you to use it for as long as you want. The latter probably wants to make an impression on you as to think they're not after you because of money.

In addition to demo accounts being free, you will probably have to provide the broker with some personal information. This is so they can keep tabs on you and try to talk you into getting a real account. 

You can also use the demo account to test different trading strategies until you find a system that works for you. You will learn how to maneuver the forex trading system without having to spend any money. This way, you will not have to concern yourself about going broke in the beginning. 

On the other hand, using a demo account can have its downsides. If you can trade foreign currency without risk, that would be good. However, doing it with risk is better; plus, with risk, there is never a dull moment. Even though you are learning with a demo account, you don't feel the real emotional effects when you profit or lose money from forex trading.

Even though a demo account has plenty of money, if you're just starting out, you may not have the amount that the demo account has. This is a psychological set up in order to show you how simple and easy it is to make tremendous amounts of money with just one or several transactions. It is easy to get tripped up if you have no parameters in place.

If you are not financially disciplined, you can end up blowing every penny you have, including your life savings while looking to make a large profit quickly. Keep in mind that when you lose a lot of money in a real forex trading account, it's no laughing matter.

In the end, demo accounts are a great tool to learn about forex trading. However, being disciplined about how much you spend to make money is key to keeping your sanity in check.
