Currency Arbitrage is the simultaneous purchase and sale of a currency in order to profit from a difference in the exchange rate. It is a risk-free form of trading that exploits discrepancies in price to generate profits. While arbitrage opportunities can arise in any market, they are most commonly found in the foreign exchange (forex) market.Due to the large number of currency pairs and the 24-hour nature of the market, forex is an ideal environment for arbitrageurs. In order to successfully execute a currency arbitrage trade, a trader must have access to real-time quotes and be able to act quickly. Thanks to the internet, it is now possible for retail traders to take advantage of these opportunities.
