Are you thinking about how to trade US stocks but hesitating due to complicated account opening processes?
In fact, for most Taiwanese investors—especially those with small or long-term portfolios—opening an overseas broker account directly is far more cost-effective than using “complex entrusted trading.”
This guide will help you understand the key differences so you can make the smartest decision.
When you decide to invest in US stocks, you first face a fork in the road: use “complex entrusted trading” through a local Taiwanese broker or bank, or open an overseas broker account directly? These two methods have their own pros and cons; understanding their core differences is the first step to making the right choice.
To make it clear at a glance, here is a table comparing the key differences between the two methods:
| Comparison Item | Complex Entrusted Trading | Overseas Broker |
|---|---|---|
| Trading Costs | Higher. Commissions ≈0.15%-1%, often with $15-$50 minimum charge. | Extremely low. Most mainstream brokers offer zero commission on stocks and ETFs. |
| Investment Products | Limited. Usually only mainstream stocks and some ETFs. | Extensive. In addition to stocks and ETFs, you can trade options, futures, bonds, etc. |
| Fund Safety | Funds stay in Taiwan, protected by Taiwan FSC regulations—psychologically reassuring. | Funds transferred overseas, protected by SIPC with up to $500,000 per account (including $250,000 cash). |
| Features & Convenience | Currency exchange handled by bank (convenient), but limited trading functions and fixed customer service hours. | Requires handling international wires yourself, but platforms are powerful (e.g., dividend reinvestment) with 24/7 online support. |
The biggest advantage of complex entrusted trading is “familiarity” and “peace of mind.” Your funds always remain in your Taiwanese bank account, and all transactions are handled through familiar local institutions without dealing with complicated international wires.
Suitable For:
- Very low-frequency traders: If you plan to trade only once or twice a year and can accept high per-trade fees.
- Extremely conservative investors: If you feel uneasy transferring funds overseas and are willing to pay extra for that peace of mind.
However, this peace of mind comes at a high price. Taiwanese brokers’ complex entrusted handling fees typically range from 0.15% to 1%, with a minimum charge. For example, even for a small trade, you may pay at least $35 or more. Over the long term, these fees significantly erode your returns.
For the vast majority of investors, opening an overseas broker account directly is the more economical choice. This has become the mainstream way for Taiwanese investors to participate in the US stock market.
The biggest attraction is zero commission. Well-known brokers like Firstrade and Charles Schwab offer zero-fee trading on US stocks and ETFs. This means you no longer pay a fixed fee per trade—extremely beneficial for dollar-cost averaging or frequent traders.
Additionally, overseas brokers have far more powerful features than complex entrusted trading. A classic example is the Dividend Reinvestment Plan (DRIP).
These powerful features and low costs are critical factors to consider when thinking about how to trade US stocks.
Now you should have a clear understanding of both methods. So which one is right for you?
Simply ask yourself: How much do you care about trading costs and investment efficiency?
- If you prioritize low cost and high efficiency, want better long-term returns, and don’t mind spending a little time learning online account opening and international remittance, then an overseas broker is undoubtedly your best choice.
- If you prioritize ease of operation and keeping funds in Taiwan, trade very infrequently, and are willing to pay extra for that convenience, then complex entrusted trading can serve as a backup option.
In summary, for the vast majority of Taiwanese investors who want to cultivate the US stock market long-term, overcoming psychological barriers and choosing a reliable overseas broker is the highest-value first step toward global investing.

Schwab provides rich research resources to help you make more professional decisions. You get free access to Schwab expert reports and third-party research from institutions like Credit Suisse and JPMorgan—something ordinary brokers cannot match.
However, Schwab’s ace feature for Taiwanese investors is the Schwab Bank Investor Checking account linked to your investment account, offering:
This gives you tremendous convenience for overseas travel, spending, or fund handling—essentially a perfect global bank account.
Note that Schwab’s international account requires a $25,000 minimum. While high, the comprehensive services and security make it absolutely worth it for investors with sufficient capital.

IBKR’s biggest feature is unmatched globalization. One IBKR account lets you invest in over 150 global markets, covering far more than US stocks—including forex, futures, bonds, etc. (Note: Taiwanese investors cannot directly trade Taiwan stocks via IBKR, but its breadth remains unmatched.
For trading costs, IBKR offers two pricing models:
| Pricing Plan | Per-Share Fee | Minimum per Order | Best For |

| Tiered | $0.0035 (starting) + exchange fees | $0.35 | Very high-volume traders |
For most people, the fixed $0.005 per share is already highly competitive. Additionally, IBKR’s margin loan rates are far lower than competitors—currently 6.83% across all tiers, very attractive for leveraged investors.
IBKR also provides the professional-grade Trader Workstation (TWS) platform and powerful API, allowing custom strategies and algorithmic trading—the true professional tool for answering “how to trade US stocks.”
In recent years, emerging internet brokers like Moomoo, Tiger Brokers, and Webull have risen rapidly. They focus on mobile experience and strong Chinese community features, deeply loved by younger investors.
Core Advantages: Native Chinese experience, active investment communities, generous signup bonuses.
Their biggest common point is strong emphasis on user experience and community interaction. You can complete all trading within the app and see other investors’ holdings, discuss hot topics, and never invest alone.

|---|---|---|---|
| Moomoo | Mobile users, prefer deep analysis | Excellent Chinese support, rich learning resources, Level 2 data | Small platform fee for US stocks |
| Tiger Brokers | Beginners, community lovers | Abundant education, active community, broader markets | Withdrawal to non-Singapore banks may incur fees |
These brokers generally offer zero-commission US stock trading but may charge a small platform fee—for example, Moomoo charges $0.0049 per share, minimum $1.99 per order. Tiger supports more markets than Webull, including US, Hong Kong, UK stocks, options, and futures.
They also frequently launch very attractive signup bonuses, such as Moomoo offering up to 15 free stocks for new users—a major reason for rapid user growth. If you like mobile operation and enjoy sharing insights with others, these emerging brokers are great choices.

After choosing your preferred broker, you enter the practical phase. Account opening and funding are not as complicated as imagined. You only need to prepare documents and follow the online process step by step to successfully open your US stock investment account. This is the most critical practice for learning how to trade US stocks.
Before starting the online application, prepare electronic versions (scans or clear photos) of the following two types of documents—this will greatly speed up your account opening.

After account approval, the final step is to wire funds from your Taiwanese bank account to the broker account. This is the last hurdle in learning how to trade US stocks. You need to provide the broker’s receiving bank information to your bank.
The most important information for international wire transfer is the SWIFT code. Think of the SWIFT code as the bank’s international ID, ensuring your funds arrive accurately.
Here is example information for wiring to a Charles Schwab account:
| Bank Name | CHARLES SCHWAB AND CO., INC. |
|---|---|
| SWIFT Code | CSCHUS6SXXX |
| Bank Address | 101 MONTGOMERY STREET, SF120KNY-13-371 |
| City | SAN FRANCISCO |
| Country | United States |
After wiring from Taiwan, funds typically take 1 to 5 business days to appear in your broker account. Due to time differences and bank processing, actual arrival time may vary.
Now you fully understand how to trade US stocks. For you, choosing the right overseas broker is the highest-value way to start US stock investing.
