I gave www.apex.exchange a fair chance. After since the beginning of the year 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: Portfolio tracking tools|Responsive team|Competitive fees|Economic calendar
Cons: Withdrawal takes 1-2 business days|Desktop app not available on Linux
