First, you should check the broker’s regulatory compliance. Is the broker you want to trade with regulated? Also, it is important to know that professional traders (such as me) only trade with regulated brokers. For example, I have different accounts with Admiral Markets, and all accounts serve a specific purpose. Some are for intraday trading, some are for scalping, some are connected to different systems I have created, etc. Second, consider the margins, spreads, and instruments a broker offers. Which types of accounts does it offer? ECN, NDD, or STP? Read different reviews about the broker across the internet. Forex Peace Army is one of the most credible websites. Finally, you need to pay attention to a broker’s customer service.
