My card was charged twice by Trade Spot AU (ts.tradespotau.com) on the same day. I had to dispute it with my bank. Trade Spot AU (ts.tradespotau.com) then froze my account and said I had a negative balance because of the chargeback. They created the problem and then punished me for it.
Pros: Wide product range|Economic calendar
Cons: Research section could be deeper|No phone support on weekends
