What is Forex?

Forex (Foreign Exchange) is the global decentralized market for trading currencies. It is the largest and most liquid financial market in the world, with an average daily trading volume exceeding $5 trillion — far surpassing all stock markets combined.

Unlike stock exchanges, the Forex market has no central physical location. Trading takes place electronically over-the-counter (OTC), connecting participants across the globe through a network of banks, brokers, and electronic trading systems.
