Forex trading enables you to speculate and potentially profit from the future direction of currencies by buying or selling the exchange rate of one currency against another.Forex – also referred to as foreign exchange and FX – is the world’s largest market with an average turnover in excess of US$4 trillion per day. Currency values rise (appreciate) and fall (depreciate) against each other due to a number of factors, including international trade or investment flows, to economic or political conditions. This is what makes trading forex so interesting and exciting – high market liquidity means that prices can change rapidly in response to news and short-term events, creating multiple trading opportunities for retail forex traders.
