Master the trading hours and viewing methods of the US stock electronic trading platform, and seize overnight opportunities.

After-hours electronic trading in the US stock market is often referred to as the “night battlefield,” and many investors want to seize this opportunity to position themselves early. However, to truly participate in this trading, you first need to understand the trading hours, quotation inquiry channels, and potential risk traps.

What exactly is the US stock electronic trading?

Electronic trading (also known as after-hours trading or night trading) is a trading model that breaks through traditional trading time restrictions. The normal trading hours for US stocks are from 9:30 to 16:00 Eastern Time, but electronic trading allows traders to continue trading outside this period.

The main participants in after-hours US stock trading are large institutional investors and well-informed investment firms. They deploy strategies in advance based on the latest news to prepare for the next day’s market trend. US stock electronic trading covers stocks listed on NASDAQ, the New York Stock Exchange, and some exchange-traded funds (ETFs).

Futures electronic trading is even more flexible, enabling 24-hour continuous trading. From crude oil and gold to various futures commodities, global investors can participate at any time to respond to market changes in real-time. Since the Taiwan Futures Exchange launched night trading in 2017, products like the Taiwan Index Futures have also allowed local investors to enjoy longer trading hours.

Five major issues to note when trading in electronic trading

1. Price discrepancies and platform limitations

Different trading platforms may show varying quotes for electronic trading. Some brokers only allow viewing quotes within their system and do not provide data from other platforms. Even if investors see a quote on one platform, it does not guarantee they can execute a trade at that price.

2. More volatile price swings

If significant news or events occur after-hours, the next day’s opening may see sharp fluctuations, increasing the risk of substantial losses. Overnight risk is a key consideration in electronic trading.

3. Widening bid-ask spreads

Due to reduced participation, the bid-ask spread (spread) often widens significantly, and investors may not be able to execute trades at prices similar to those during regular trading hours.

4. Limit order requirements

Most after-hours US stock markets only accept limit orders, requiring investors to set their own execution prices, take-profit points, or stop-loss points. If the market price deviates too far from the set price, the order may not be executed.

5. Risks of automated matching systems

US electronic trading is fully automated, and system delays or failures can directly impact trade execution efficiency.

Weighing the advantages and risks of electronic trading

Core advantages of participating in electronic trading

• More flexible trading hours: Breaks through regular trading time restrictions, reflecting market information before and after hours, allowing investors to react promptly

• Increased market participation: Global investors can participate in the same market without regional restrictions, expanding trading volume and making the market more fair and transparent

• Overnight positioning opportunities: Investors can deploy potential stocks based on overnight news or use short-term volatility for trading

Important risks to consider in trading

• Disadvantage against large institutions: Retail investors face competition from larger, resource-rich institutions with more comprehensive information outside regular hours, often at a disadvantage

• Lack of liquidity: After-hours trading volume decreases, making it difficult to find suitable trading counterparts for some securities; some products may even have no trades for extended periods

• System risks: Fully relying on automated matching systems can lead to delays or failures due to system issues

Conclusion

US stock electronic trading offers investors greater flexibility in time and space, but this does not mean frequent trading is encouraged. Investors should fully understand the advantages and risks of electronic trading (especially price volatility and liquidity issues), confirm specific rules with their trading platform, and then make rational investment decisions. Mastering the inquiry channels and risk management before seizing opportunities in US stock electronic trading is the key to success.
