TradeZero is an equity and options brokerage headquartered in the Bahamas that focuses on high-quality order execution. Founded in 2015, TradeZero provides a US-centric asset selection and a subscription-based trading platform, but its mobile app remains free. After concluding my TradeZero review, I can recommend it to traders who wish to trade US-listed assets, including OTC stocks with intraday leverage of 1:6. Is TradeZero the best broker for your portfolio?
