One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over-the-counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney—across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.

Just like stocks, you can trade currencies based on what you think about its value (or where it goes). But the big difference with forex is that you can trade up or down just as easily. If you think that the currency will grow in value, you can buy it. If you think it will decrease, you can sell it. With such a large market, finding a buyer when you sell and a seller when you buy is much easier than in other markets. You may have heard in the news that China devalues its currency in order to attract more foreign business to its country. If you think that this trend will continue, you can make a deal in the Forex market by selling Chinese currency for another currency, say, the US dollar. The more the Chinese currency depreciates against the US dollar, the higher your profit. If the Chinese currency rises in price when you have a sell position, your losses grow and you want to exit the trade.
The problem is that this is where traders are most likely to succumb to overconfidence bias. It's not uncommon for traders to complete a winning streak and then believe that they can't get anything wrong in the future. To believe this is of course unwise, and is only going to end in failure. Make sure you always analyse your trading sessions and look at your wins and losses in detail.
