Consider Your Needs
Before looking at brokers, assess your own needs. Here are some things to consider:
Are you going to day trade a lot or a little? Trade very small moves, or capture bigger moves? If you day trade a lot and capture small moves, consider an ECN broker. You'll pay a commission on trades but the spreads are much tighter, which matters when trading small moves. Search only for "ECN Forex Brokers."
If you don't think you'll need an ECN broker, then you still have a big pool of potential brokers left.
