Day trading for most people is not as it is portrayed in the media. It is not the get-rich-quick scheme it is often shown to be. The guide to profitable Forex day trading could be considered controversial, as it is something that everyone has an opinion about. What everyone agrees on however, is that it is a very risky activity and should only be considered if one has an in-depth knowledge of the market, and a clear understanding of those risks.
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.
