Pretty much all ECN forex brokers offer at least a few currency pairs for trading, hence the name “forex broker”. Among the most common currency pairs that are offered by ECN forex brokers and others are the so-called major pairs, which includes the EUR/USD, USD/JPY, GBP/USD, AUD/USD, USD/CHF, NZD/USD, and USD/CAD.
Currency trading via the ECN model is most popular among professional and high-volume traders due to the lower spreads that comes with this type of trading. As opposed to dealing desk or market maker brokers, ECN brokers pass orders directly on to a network shared with other brokers where trades are matched with each other. When trading currencies with a true ECN forex broker, the spreads displayed are therefore the true prices offered by other market participants.
