Network. It is actually an electronic trading network, a foreign exchange trading technology with centralized-decentralized market structure. This model is completed through close cooperation with banks, institutions, foreign exchange markets and technology suppliers. Traders' orders are directly and anonymously hung on this network, and each order is in the same location, and the transaction is carried out according to the optimization of price and time. So broadly speaking, ECN mode includes STP, DMA, MTF and other trading modes or equivalent modes that really put retail orders into the market.
