CFDs are not suitable for everyone.  The main risk is that you may be asked to pay more than your initial investment if the market goes against you.  Before you decide to invest, ask yourself the following questions:

• Do you fully understand how CFDs work?
• Do you understand how you can make money and, more importantly, how you can lose money in these investments?
• Are you in a position financially to lose all of the money you are thinking of investing, and possibly more?
• Do you accept that the outcome of your investment may be that you will have to provide additional money if the market goes against you?
• If matters do go against you, do you understand how much extra you might need to pay and have you got the funds to do this?
