What does a Trading Session Mean?

A trading session refers to the designated period during which trading activities occur in financial markets. Each trading session is typically defined by the open and close bells of the respective market, encompassing one business day. The duration of a trading session varies across markets and countries by the cause of contradicting time zones.

Explaining a Trading Session

Trading session hours differ based on the country and the class of the asset. In the United States, orderly trading for stocks takes place from 9:30 a.m. till 4:00 p.m. ET on weekdays, with the New York Stock Exchange (NYSE) setting the main trade hours. The U.S. bond market follows an orderly weekday trading session from 8:00 a.m. till 5:00 p.m. ET. Though, futures markets can have varying trade hours that depends on the exchange and commodity type.

Pre-Market and Post-Market Trading

Beside orderly trade hours, some markets provide pre-market and post-market trading sessions. Pre-market trading for U.S. stocks occurs from 4:00 a.m. till 9:30 a.m. ET on weekdays, while post-market trading takes place from 4:00 p.m. till 8:00 p.m. ET. These extended sessions enable investors to capitalise on significant news and other circumstances that take place outside orderly trade hours. It's crucial for traders to know these sessions and their corresponding hours to avoid any unpredictable issues during their trade activities.

24-Hour Trading

The foreign exchange market operates as a 24-hour market, providing the advantage of continuous trading. This global market allows investors from different time zones to trade currencies at any time. However, not all trading sessions within the 24-hour period are equal in terms of activity and volatility. The forex market can be fractured into three primary trading sessions: the Asian session, the European session, and the North American session. Each session has distinct characteristics based on the demographics of market participants and their online presence during specific times. Overlapping sessions, such as Europe and North America, can lead to heightened volatility.

What are the Best and Worst Times to Trade?

The best and worst times to trade depend on the asset class you are referring to, such as stocks or forex. Let's address each asset class separately:

Stocks:

The best time to trade: The first and the last hours of a trade day are generally the most active and offer the most abilities for traders. During the opening hours, market volumes and costs can be volatile as they factor news since the previous closing bell. Skilled day traders often find the first quarter of an hour next to the opening bell to be prime time for trading, since it generally offers some of the biggest day trades based on initial trends. The time from 9:30 a.m. till 10:30 a.m. ET is repeatedly considered one of the best hours for day trading, with significant changes occurring in a short period of time. However, it's important to note that the middle hours of the trade day are usually the calmest and most stable period of time with less volume and smaller moves.

Forex:

The best time to trade: The foreign exchange market works 24/7, as it follows the business hours of various parts of the world. The best trade abilities in the foreign exchange market often occur during the overlapping hours of major market sessions. The U.S./London markets overlay from 8 a.m. to noon EST, offering the heaviest volume of trading and potentially more trading opportunities. Another notable overlap is the Sydney/Tokyo markets from 2 a.m. to 4 a.m. EST, which, although less volatile than the U.S./London overlap, can still present trading opportunities. It's important to consider that specific currency pairs may exhibit different levels of activity and volatility during different market sessions.

What are the Major Trading Sessions Around the World?

The main trading sessions are the following:

Asian Session:

Time: 00:00 - 09:00 GMT (local time: 9:00 a.m. - 6:00 p.m. in Tokyo)

Key Characteristics: The Asian session is the first forex session to open. It accounts for approximately 6% of the world's forex transactions. Many large participants, including banks and institutions, use the trade momentum in Asia to develop their strategies and gauge future market dynamics.

European Session:

Time: 08:00 - 17:00 GMT (local time: 8:00 a.m. - 5:00 p.m. in London)

Key Characteristics: The European session is the largest and most important foreign exchange trading session globally. It holds roughly a 34% market share of the daily forex volume. London is home to many important banks and has a high concentration of market participants. The European session tends to be more volatile than the other sessions due to the influx of liquidity.

US Session:

Time: 13:00 - 22:00 GMT (local time: 8:00 a.m. - 5:00 p.m. in New York) 

Key Characteristics: The US session is the second largest trading market, handling approximately 16% of the world's forex transactions. The most active period in the US session occurs during the overlap between the US and European sessions. As liquidity dries up and European traders exit the market, the trading activity slows down.

It's important to note that these sessions are not rigidly defined and can overlap at certain times, especially during periods of daylight saving time changes in different countries. 

Bottom Line and Key Takeaways

Understanding trading sessions is crucial for investors and traders as it helps them determine the optimal times to engage in trading activities. Different markets have their own trading session hours, which may vary based on asset class, country, and exchange. It's essential to be aware of the opening and closing times of the markets and assets being traded to effectively plan trading strategies. The availability of pre-market and post-market trading sessions provides opportunities to react to news and events outside regular trading hours. Traders should always stay informed about the specific trading sessions and their corresponding hours to make informed decisions and manage their risks.

The best times to trade stocks are often during the first and last hours of the trading day, with increased volatility and opportunities. However, the middle of the trading day tends to be calmer. For forex trading, the overlapping hours of major market sessions, such as the U.S./London overlap and the Sydney/Tokyo overlap, provide potential trading opportunities. It's important to remember that these patterns are general observations, and individual trading strategies should consider other factors, including market conditions, volatility, and personal risk tolerance.

Understanding the major trading sessions can help traders develop effective trading strategies and take advantage of periods with higher trading volumes and potential opportunities.
