DMA (direct market access) forex brokers in Germany are always regulated by both the common European regulator known as the European Securities and Markets Authority (ESMA), as well as by the national regulator BaFin. As a result of this arrangement, CFD & forex brokers regulated in Germany are also allowed to offer their services to residents in any other EU & EEA country.
As an order processing model, DMA is the opposite of the dealing desk model that many retail-focused brokers rely on today. Instead, DMA is similar to the STP (straight-through processing) model in the way that orders are passed directly on by the broker instead of being matched internally, which is what happens at dealing desk brokers. In general, DMA brokers offer lower spreads between buy and sell prices than dealing desk brokers.
