I've been trading US stocks for over six years, and I've tested nearly every brokerage that caters to Chinese investors. US Tiger Securities kept popping up in forums, so I gave it a real shot – opened an account, funded it, and traded actively for three months. Here's everything I found, the good and the bad, with zero fluff.
What Is US Tiger Securities?
US Tiger Securities, Inc. is a US-based broker-dealer registered with the SEC and FINRA. It's part of the Tiger Brokers group, which also has a Singapore arm. The firm specifically targets Chinese-speaking investors who want to trade US stocks, ETFs, options, and even fractional shares. Think of it as a bridge between the Chinese market and Wall Street – but with some quirks.
I found their onboarding surprisingly smooth. You can open an account entirely online, and they accept Chinese IDs (passport or national ID) for verification. No need for a US social security number. But – and this is a big but – the minimum deposit is $3,000 for a margin account. That caught me off guard.
Fees & Commissions – The Real Cost
Let's cut to the chase. US Tiger advertises $0 commission on US stock and ETF trades. Yes, that's real – but you need to dig into the fine print.
| Fee Type | Amount | Notes |
|---|---|---|
| Stock/ETF Commission | $0 | Market and limit orders only; some order types like stop-limit may still be $0 |
| Options Commission | $0.65 per contract | Competitive, but not the lowest (Robinhood is $0, but for US residents only) |
| Margin Interest | 6.99% (base rate) | Varies by balance; lower than many Chinese brokers but higher than interactive brokers |
| Account Inactivity Fee | $15/month | If you trade less than 2 times per quarter – this is a killer for casual investors |
| ACH Withdrawal Fee | $0 (first 2 per month) | Then $5 each; wire transfers cost $25 |
That inactivity fee is a nasty surprise. I nearly got hit myself. In my second month I only placed one trade (I was testing their research tools), and boom – a $15 charge appeared. Luckily they waived it as a one-time courtesy. But if you're a buy-and-hold investor, this broker will cost you.
Account Types: Which One Fits You?
US Tiger offers three main account types: Cash, Margin, and IRA. The IRA is for US residents only, so for Chinese investors, you're looking at cash or margin.
Cash Account
No minimum deposit. You can only trade with settled funds. Great for beginners, but settlement takes T+2, so you can't flip stocks intraday. I started with a cash account to test the waters.
Margin Account
Requires $3,000 minimum. You get 2:1 leverage intraday and 1:1 overnight for most stocks. I eventually switched to margin because I like day trading, and the margin rates are reasonable. But again – the minimum is steep compared to some US brokers like Robinhood (no minimum).
Trading Platform – Mobile vs Desktop
The mobile app is clearly their star. It's available in Chinese and English, and the UX is clean – reminiscent of Robinhood but with more data. I particularly like the real-time level 2 quotes (included for free) and the social feed where you can see what other users are buying. That social feature feels like a double-edged sword – great for ideas, but dangerous if you follow the herd.
The desktop platform, Tiger Trade, is a bit clunky. Charts are decent but not as customizable as Thinkorswim or TradingView. I had a few crashes during high volatility (think CPI releases). Also, the screener is basic – you can't filter by advanced metrics like short interest or insider transactions. That forced me to use a third-party screener.
I remember one time trying to place an iron condor on the desktop app – the interface was so confusing I accidentally submitted a naked call. Had to cancel it immediately. That's when I realized the platform is built more for stocks than complex options.
Pros & Cons (From a Heavy User)
| Pros | Cons |
|---|---|
| Zero commission on US stocks/ETFs – real $0 | Inactivity fee of $15/month – punishes buy-and-hold |
| Excellent Chinese language support, 24/7 WeChat help | Desktop platform lags behind leaders |
| Fractional shares available (down to 0.001 share) | Limited research tools – no Morningstar or CFRA reports |
| Level 2 quotes included for free | No forex or futures trading |
| Fast account opening with Chinese ID | Margin minimum $3,000 is high |
Honestly, the inactivity fee is a dealbreaker for many. I've seen complaints on Reddit and Chinese forums (like xueqiu) about people being charged months after they stopped trading. US Tiger is great for active traders, but if you plan to hold long-term, consider a broker like Charles Schwab or Interactive Brokers.
US Tiger vs Schwab vs Interactive Brokers
Here's the short version: Schwab has zero inactivity fees, better research, and a more robust platform, but its Chinese support is weaker. Interactive Brokers has the best rates for margins and currency conversion but a steep learning curve.
- US Tiger wins on: Chinese language support, ease of funding from China, fractional shares.
- Schwab wins on: No inactivity fee, excellent customer service, massive mutual fund selection.
- Interactive Brokers wins on: Low margin rates, global market access, advanced tools.
I personally keep both Tiger and IBKR. Tiger for quick Chinese stock hunts and social tips, IBKR for serious portfolios and options.
