In forex trading, arbitrage refers to the practice of taking advantage of price differences between different markets or currency pairs. Arbitrageurs seek to buy a currency in one market where it is undervalued and simultaneously sell the same currency in another market where it is overvalued, thus profiting from the price difference. The process of arbitrage tends to occur quickly as market participants seek to eliminate the price difference, resulting in a correction in the exchange rates. Forex arbitrage opportunities are often fleeting, and traders must act quickly to take advantage of them. The use of high-speed trading algorithms has become increasingly common in the pursuit of forex arbitrage opportunities.
