The forex market is the largest financial market in the world and infused with the largest amount of capital, where different currencies from various countries are bought, sold, and exchanged with one another. Unlike other financial markets, there is no specific location for the forex market, and trading is primarily conducted through the electronic networks of banks and forex brokers. For investors, the best trading opportunities tend to be the most liquid currencies, such as the U.S. dollar, Japanese yen, Euro, pound sterling, Swiss franc, and other mainstream currencies.

Foreign exchange margin trading originated in London in the 1980s and was subsequently expanded to Hong Kong and other global markets. It refers to investment behavior where investors conduct forex trading with financing provided by banks or brokers and create profits through exchange rate fluctuations. Foreign exchange margin trading attracts global investors due to its many advantages, but it is also necessary to be aware to the potential risk of losses brought by the highly leveraged model.
