Since Estonia is part of the EU, trading leverage with Estonian forex brokers is generally restricted to a maximum of just 1:30. However, some of the forex brokers that are regulated in Estonia are also regulated in other countries with more relaxed regulations. When trading with one of these brokers, it may be possible to get much higher trading leverage than what is normally available within the EU.
An Estonian forex broker may for example also have local entities that are regulated in countries like Australia, or even in offshore countries in the Caribbean. Here, trading leverage often goes up to 1:500. Which entity you get to trade with, however, usually depends on your residency. Quite often, EU residents will be directed to trade only with the EU-regulated entity.
