I was disappointed with Zixfx. Despite their promises of low spreads and commission rebates, I found that the spreads were much higher than advertised, and I never received the promised commission rebates. On top of that, the withdrawal process was slow and frustrating. It's frustrating when a broker doesn't live up to their promises, and that's exactly how I felt about Zixfx. I wouldn't recommend this broker to anyone who wants a reliable and transparent trading experience.
