Investing in currencies, stocks, and other investment products is of the market nature and always involves significant risks. Because of sharp market fluctuations, you may both make much of your investments and completely lose them.
You may manage the risks (the ratio of possible financial losses to profits) by using the credit line value, and specific types of orders (Stop Loss / Take Profit) or other available tools. You should always remember that the higher the credit line and possible profit, the higher the risk level.
