What Is a Trading Session?

A single business day in a financial market from that market’s opening bell to its 澳洲幸运5官方开奖结果体彩网:closing bell is typically its trading session. The markets for forex, futures, stocks, and bonds all have their own characteristics that define their respective trading sessions for a given da🔴y. The primary trading hours naturally♓ differ from one country to another due to contrasting time zones.

How a Trading Session Works

Trading session hours can vary by 澳洲幸运5官方开奖结果体彩网:asset class and country. The regular trading session for U.S. stocks starts at 9:30 a.m. and ends at 4:00 p.m. Eastern Time (ET) on weekdays (holidays excepted). These times are primarily driven by the working hours of the 澳洲幸运5官方开奖结果体彩网:New York Stock Exchange (NYSE), which closes early at 1:00 p.m. ET on several occasions throughout the year associated with holidays.

The regular weekday trading session for the U.S. bond market is 8:00 a.m. to 5:00 p.m. ET. Futures markets, meanwhile, have different trading hours, de🦋pending upon t🅰he exchange and the type of commodity being traded.

In addition to regular trading hours, some markets may have pre-market or 澳洲幸运5官方开奖结果体彩网:after-hours trading sessions. Other markets even have 24-hour trading 𝓰ses𒊎sions.

Pre-Market and After-Hours Trading Sessions

Pre-market trading for U.S. stocks occurs between 4:00 a.m. and 9:30 a.m. ET on weekdays. After-hours trading, on the other hand, is from 4:00 p.m. to 8:00 p.m. ET on weekdays, although these times may vary slightly by exchange.

Pre-market and after-hours trading is a compelling way to capitalize on important news announcements or other factors that occur outside of regular trading hours. With that in mind, here are several factors that investors should be mindful of when trading outside of regular hours. In particular, the 澳洲幸运5官方开奖结果体彩网:Securities and Exchange Commission (SEC) notes eight such risk factors:

1. Inability To See or Act on Quotes: Some brokers only allow investors to view quotes from their own trading system rather than other 澳洲幸运5官方开奖结果体彩网:electronic communication networks (ECNs).
2. Lack of Liquidity: There are fewer traders involved with after-hours trading, so there’s typically a lot less 澳洲幸运5官方开奖结果体彩网:liquidity than during regular trading sessions.
3. Larger Quote Spreads: Less trading activity often translates to wider 澳洲幸运5官方开奖结果体彩网:bid-ask spreads, which could make order execution difficult.
4. Price Volatility: There may be greater fluctuations than during regular hours, particularly if there’s a breaking news story with significant market repercussions.
5. Uncertain Prices: The price of stocks traded after-hours may differ from those traded during regular trading sessions.
6. Bias Toward Limit Orders: Many ECNs only accept 澳洲幸运5官方开奖结果体彩网:limit orders rather than 澳洲幸运5官方开奖结果体彩网:market orders during after-hours sessions.
7. Competition with Professional Traders: Many after-hours traders are professionals with large 澳洲幸运5官方开奖结果体彩网:institutions that have access to more information.
8. Computer Delays: There is less technical support available during pre-market or after-hours trading sessions, so you could encounter trade execution delays.

24-Hour Trading Sessions

There are some markets with a 24-hour trading session. Among the most notable is the global foreign exchange (forex) market, in which currencies are traded. The forex market is the largest, most liquid market in the world.

Unlike the equity market, the forex market has no physical exchange. Rather, it consists of several large banks and brokerage firms that trade currencies with themselves. The forex market is open 24 hours a day, five days per week, from Sunday evening until Friday night.
