Moomoo

MooMoo is the U.S.-facing brand of Futu Holdings (NASDAQ: FUTU), a Chinese-founded fintech that built its reputation in the Hong Kong and Singapore markets before expanding to the U.S. in 2018. The platform targets active retail investors — day traders, options traders, and swing traders — with features that rival thinkorswim or Interactive Brokers at a fraction of the learning curve. Level 2 market data is free for U.S. equity customers (a notable feature given that most brokerages charge $25–$75/month for this), and the mobile app is widely considered among the most polished in the category.

Commission-free trading covers U.S. equities, ETFs, options, and Hong Kong/Chinese equities (the last being a legacy advantage from Futu's origins). Cash sweeps earn up to 5.50% APY on uninvested balances (rate subject to change), which is among the highest in the industry, and margin rates start at 6.30% for balances over $100,000 — competitive but not best-in-class. The platform's most notable gap is retirement accounts: MooMoo does not currently offer IRAs, 401(k) rollovers, or any tax-advantaged account types, which is a meaningful limitation for long-term investors.
