FOREX

With most Forex brokers when you leave a currency pair position open over the night you’ll get a swap or an interest payment for it. It can be positive (you actually gain money) or negative (you lose money). That payment is usually very small and the majority of the beginning traders just don’t pay any attention to it, since their direct profit or loss from the trading is much greater than this rollover interest. But why do the brokers pay and take this overnight interest payment or swap?
