You can open a demo account by registering as an investor or a trader. It is a fairly simple process where you pick a username, give your email and a password and you are ready to go.
The demo account is a great way to practice your trading skills before you are ready to put actual money on the line.
Once you have registered and decided you want to switch from demo to a live account, you deposit your funds with the minimum for an individual account being €/$/£500 and €/$/£100 for a corporate account.
You can deposit funds via Skrill, Visa, Neteller, bank transfer and Union Pay.
An interesting thing that the Darwinex broker has done is they have allowed you to link your MT4 accounts from other brokers to Darwinex. This allows you to use your previous track record for analytical purposes. However, they only put Darwin accounts on their lists to ensure that both you and their investors get the best service possible.
