I had a dispute with cfd.eliteai-t.com 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: Clear documentation|No hidden fees|Automated trading options|Competitive fees
Cons: Wait times can be long during peak hours
