I had a dispute with Financial Assurance Regulatory Board and went to their complaints process. They have an internal team that just defends the company. Then they said I could go to an ombudsman - but the ombudsman they use is industry-funded and rarely rules for the client. The system is rigged.
Pros: Multiple order types|Comprehensive tools
Cons: Wait times can be long during peak hours|Withdrawal takes 1-2 business days
