When participating in U.S. pre-market trading, you need to pay attention to the trading hours. The U.S. pre-market session generally runs from 4:00 AM to 9:30 AM Eastern Time. This period is earlier than regular market hours, allowing you to deploy investment strategies sooner. According to exchange and official statistics, daily trading data and transaction details record the transaction status during the pre-market session. You can refer to this data to understand the activity level of the pre-market. If you are in Hong Kong, summer time is 12 hours ahead of Eastern Time, and winter time is 13 hours ahead. You need to adjust your order placement time based on the time difference to avoid missing the best pre-market opportunities.
During the U.S. pre-market session, you can only trade exchange-listed stocks. These stocks include companies listed on the New York Stock Exchange (NYSE) and NASDAQ. You cannot trade OTC (over-the-counter) stocks during the pre-market session, as most platforms do not support pre-market trading for these stocks. When selecting stocks, remember to check whether the stock supports pre-market trading. This can reduce the likelihood of order failures.
During the U.S. pre-market session, you can only use limit orders. Limit orders allow you to set the buy or sell price, and the system will only execute the trade when the set price is reached. Due to lower liquidity in pre-market trading, the likelihood of execution depends on the number of opposing orders. When placing orders, note that price fluctuations may be significant, and execution speed may not be as fast as during regular hours. You can monitor pre-market quotes and trading volumes more closely, adjust your order strategy, and increase the chances of execution.

Most mainstream platforms, such as TD Ameritrade, Webull, Futu Niuniu, Phillip POEMS, and Sin e-Invest International, support pre-market trading from 4:00 AM to 9:30 AM Eastern Time. Some platforms require you to actively enable pre-market trading permissions after opening an account. You can find the relevant options in the platform settings to enable pre-market trading.

Tip: Pre-market trading has low liquidity and significant price fluctuations. When placing orders, monitor quotes and trading volumes to avoid chasing prices too high or too low.
Sample Operation Process (Using Webull as an Example):
Reminder: Each time you place a U.S. pre-market order, check whether pre-market trading permissions are enabled, and note that only limit orders can be used.
During U.S. pre-market trading, you often encounter low liquidity. This means there are fewer buy and sell orders, limiting execution opportunities. Low liquidity makes it harder to trade at your desired price, especially for large transactions. You can refer to the table below to understand how liquidity reference indicators are calculated. Higher values indicate poorer liquidity and greater difficulty in execution.
| Product Name | Expiration Month | Open Interest (Contracts) | Average Trading Volume (Contracts) | Liquidity Reference Indicator |
|---|---|---|---|---|
| Taiwan Stock Futures (TX) | 202509 | 3082 | 92 | 33.50 |
| Taiwan Stock Futures (TX) | 202512 | 942 | 22 | 42.82 |
| Taiwan Stock Futures (TX) | 202603 | 376 | 30 | 12.53 |
You can use statistical reports from exchange websites to observe trading volumes and volatility in different sessions, helping you assess liquidity risks in U.S. pre-market trading.
During the U.S. pre-market session, bid-ask spreads are typically wider than during regular hours. When placing orders, you may notice a significant gap between the buy and sell prices. This increases your trading costs. You should monitor real-time quotes closely and avoid chasing prices when spreads are too wide. Consider setting more conservative limit orders to reduce the risk of losses due to large spreads.
During U.S. pre-market trading, not all stocks are available for trading. Most platforms only support exchange-listed stocks and do not support OTC stocks. Before placing an order, check whether the stock supports pre-market trading. Some platforms also impose restrictions on order quantities or minimum transaction amounts. Read the platform’s rules carefully to avoid order failures due to non-compliance.
Tip: If you encounter unclear trading restrictions, contact the platform’s customer service to inquire and reduce unnecessary losses.
