I gave Impersonation of Nord Australia Pty Ltd (trade-markets.com) a fair chance. After for a couple of months now of usage, I can say with confidence that there are far better options available. The interface is clunky, the fees are higher than competitors, and the customer support team seems overwhelmed or understaffed.
Pros: Intuitive for beginners|API access|Tax reports included|Economic calendar
Cons: Limited social trading features
