For example, if you invested 5,000 EUR and lost 1,000 EUR, you will have lost 20% of your balance, leaving you with a final balance of 4,000 EUR. To bring your balance back to 5,000 EUR, you will need to make a profit of 1,000 EUR. However, with a starting balance of 4,000 EUR (after the previous loss), there is now a 25% gain, rather than a 20% one.
Spot for most currencies is two business days; the major exception is the U.S. dollar versus the Canadian dollar, which settles on the next business day. Other pairs settle in two business days. During periods that have multiple holidays, such as Easter or Christmas, spot transactions can take as long as six days to settle. The price is established on the trade date, but money is exchanged on the value date.
Whether you are a beginner trader or a pro, it is best to trade with what you see and not what you think. For example, you might think that the US dollar is overvalued and has been overvalued for too long. Naturally, you will want to short and you might be right eventually. But if the price is moving up, it does not matter what you think. In fact, it doesn't matter what anybody thinks – the price is moving up and you should be trading with the trend.
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.
