To use an extreme example, imagine holding an account balance of 2,000 EUR and putting all of that on a single trade. If the trade goes badly, you will have lost your entire investment, and because the Forex market can move very quickly, losses can also happen very quickly. This is where risk management is essential - to help you minimise losses and protect any profits you do make. The key areas to consider when managing your Forex trading risk are trading psychology, and money management.
The foreign exchange market is where currencies are traded. Currencies are important to most people around the world, whether they realize it or not, because currencies need to be exchanged in order to conduct foreign trade and business. If you are living in the U.S. and want to buy cheese from France, either you or the company that you buy the cheese from has to pay the French for the cheese in euros (EUR). This means that the U.S. importer would have to exchange the equivalent value of U.S. dollars (USD) into euros. The same goes for traveling. A French tourist in Egypt can't pay in euros to see the pyramids because it's not the locally accepted currency. As such, the tourist has to exchange the euros for the local currency, in this case the Egyptian pound, at the current exchange rate.
