ECN (Electronic Communication Network) selects the most favorable price for customers to hold positions among banks and foreign exchange trading platforms, and brokerage companies earn appropriately low commissions. The cost of ECN is mainly spread, and its spread is not fixed. For example, when active, Eurodollar is generally 1 spread, and ECN brokerage companies do not earn spread fees.

Therefore, there are few pure ECN platforms on the market, and many of them are under the guise of ECN or STP mode. As far as I know, Dukascopy in Switzerland belongs to ECN trading mode (Dukascopy Bank in Switzerland itself); So are Presley, foreign exchange software and FXDD.
