My current choice is [URL deleted] FP Markets. Having had experience with other Australian brokers I can say they're easily one of the best. First of all I always choose a broker who has a 24h great customer service. It's easy to test them on live chat to see how knowledgeable and helpful they are. No spread widening issues like the other brokers, lower commission, no depositing or withdrawing fees with my visa card, ecn pricing and fast execution. Slippage is low but I'm very careful as well. So far so good, gaining confidence.
