Foreign exchange companies, namely foreign exchange brokers, can provide foreign exchange trading services for retail investors. The foreign exchange market is over-the-counter and there is no central exchange. Although stocks can also be carried out through online platforms, stock transactions are cleared through exchanges, and the norms are relatively strict. Online foreign exchange platform and online stock trading are not the same concept. The standard level of foreign exchange trading is poor, and there is no mandatory requirement for brokers to disclose trading records. Therefore, it is worth spending time to study the differences between different brokers and choose reliable foreign exchange brokers. Before you start trading, you need to know the rules of brokers and their operation mode. For example, ECN and STP are different from MM mode. Baidu Soso knows that FX broker FXOpen provides ECN and STP trading platforms.
