Currency trading with leverage implies an important risk for the investor and there is always the possibility of losses. These instruments carry a high risk if they are not managed properly and a profit can quickly become loss as a result of price changes. Due to the risk factor inherent to this type of trade, only funds intended for risk investments should be used. If you do not have extra capital you may be willing to lose, you should not trade in the forex market. It has never been proven that there is any system or portfolio of systems that is completely safe and no one can insure future profits or losses. Before you start trading in the forex market you should think carefully about your goals as an investor, your level as an investor and your risk aversion to determine if this is the type of investment you want to make. If you are in doubt you should seek advice from a professional financial advisor to advise you about the investment.
