Before you can choose a broker, you have to know who or what constitutes one. There are two types of brokers out there: those who deal directly with their clients (regular brokers), and those who act as intermediaries between the client and a larger broker (broker-resellers). There comes a time when you've got to make that decision and choose a broker. It's absolutely necessary to balance your needs as an investor and as a client - good customer service is essential, too. While your first broker won't necessarily be your broker for life, you have a much better chance of making money as an investor if you put the right amount of time and research into choosing a broker.
