All times below are in Hong Kong Time (HKT, UTC+8).

• Hong Kong stocks: 09:30–12:00 and 13:00–16:00 on Hong Kong trading days
• U.S. stocks during daylight saving time: 21:30 to 04:00 the following day

Fees are charged on both purchases and sales. Actual fees are subject to the amount displayed on the order confirmation page.

8. What Are Market Orders and Limit Orders?

A market order attempts to execute at the best available market price at that time. The actual execution price may vary due to market fluctuations.

A limit order attempts to execute only at the specified price or a better price. It may be partially filled or remain unfilled.

Before placing an order, please confirm the order direction, quantity, price, validity period, and applicable fees.

9. How Long Does an Order Remain Valid? Can I Cancel It?

UEEx currently supports Day Orders and 7-Day Orders.

• Any unfilled portion of a Day Order will automatically expire after the market closes on the same trading day.
• Any unfilled portion of a 7-Day Order will automatically expire when its validity period ends.

If an order has not been fully filled and remains eligible for cancellation, you may submit a cancellation request on the order details page. Whether the cancellation is successful is subject to the actual processing result of the upstream service provider.

10. Why Was My Order Not Filled, Partially Filled, or Unable to Be Placed?

Common reasons include:

• The market is outside its trading hours
• The security is suspended or temporarily unavailable for trading
• Insufficient funds
• The order quantity does not meet the minimum trading unit
• The specified limit price has not been reached
• Insufficient market liquidity
• The market or upstream trading channel is experiencing an operational issue

Please refer to the order details page and on-screen notifications for the applicable status.

11. When Will Funds Become Available After Selling Stocks? Can I Withdraw Them?

You will receive USD after selling U.S. stocks and HKD after selling Hong Kong stocks.

The proceeds will be credited to the available balance of your stock account in accordance with the rules displayed by UEEx and may be used for further trading. When the applicable requirements are met, USD or HKD may be converted into USDT and withdrawn.

Market closures, order status, risk controls, and upstream processing may affect when the funds become available for trading or withdrawal.

12. Can I Withdraw My Stocks or Transfer Them to Another Broker?

Transfers of stocks into or out of UEEx to another broker are currently not supported.

You may sell your holdings through the UEEx stock trading page, convert the available USD or HKD into USDT in accordance with the applicable on-screen rules, and then withdraw the USDT.

13. Can I Receive Dividends? Why Is the Dividend Amount Received From U.S. Stocks Lower Than Expected?

Holdings that meet the issuer’s ex-dividend date, record date, and other applicable requirements may be eligible to receive dividends.

Dividends from U.S. stocks are generally credited in USD, while dividends from Hong Kong stocks are generally credited in HKD. The actual amount and crediting time are subject to the final processing results.

U.S.-source dividends may be subject to withholding tax. The actual tax rate depends on applicable laws, tax treaties, the user’s tax information, and the withholding applied by the upstream service provider.

14. How Will Stock Splits, Reverse Stock Splits, Mergers, or Acquisitions Affect My Holdings?

Corporate actions may affect the number of shares held, the price per share, the security’s trading status, or your cash balance.

Stock splits and reverse stock splits generally adjust the number of shares and the price per share proportionally. Mergers, acquisitions, privatizations, or spin-offs may result in new securities, cash compensation, or a combination of both.

UEEx will update holdings and account balances based on the issuer’s announcements and the actual processing results provided by the upstream service provider.

15. What Should I Do During a Trading Suspension, Circuit Breaker, or Order Issue? How Can I Contact Customer Support?

During a trading suspension, circuit breaker, market protection mechanism, extreme market conditions, severe weather, or an upstream trading channel disruption, orders may be delayed, queued, partially filled, rejected, or cancelled.

Please first check the order status and announcements on the stock trading page. If you require assistance, contact online customer support and provide the following information:

• Your UEEx UID
