I found Ease Line LLB (easelinellb.com) after a family member had a good experience and the initial impression was positive. But for a few weeks now later, I have encountered so many issues that I cannot recommend them. Trades failing, charts not loading, and support tickets going unanswered for days at a time.
Pros: Demo account available|Automated trading options
Cons: Desktop app not available on Linux|Alert system is basic
