Optimal Forex Trading Hours Analysis for Vietnamese Traders

2025-12-26 10:11:49

Want to seize the best profit opportunities in the forex market? The first step is to understand the forex trading sessions and the times with the highest volatility. Although the forex market operates 24 hours a day, it is not always the ideal time to trade. Therefore, choosing the right forex trading hours will determine your success or failure.

The Four Main Trading Sessions Worldwide

The forex market is divided into four main trading sessions, each corresponding to major economic regions:

Sydney Session (Australia) - The opening session in the global trading day
Tokyo Session (Asia) - Focused on Japanese Yen trading
London Session (Europe) - The session with the largest trading volume
New York Session (America) - The last session of the day

In reality, three sessions—Asia (Tokyo), Europe (London), and North America (New York)—account for most of the trading volume. Professional traders often focus on one or two of these sessions rather than trying to trade continuously.

An interesting fact is that the top four trading centers—London, New York, Singapore, and Hong Kong—account for up to 75% of global forex revenue.

To help you easily follow, here is a table of opening and closing times for each session:

Tokyo Session: 6h - 15h (GMT+9)
London Session: 14h - 23h (GMT+1)

Opening times may vary depending on daylight saving time (DST) policies in different countries, usually occurring in March, April, October, and November.

Golden Overlap Periods Between Sessions

When two or more trading sessions overlap, the market tends to be more volatile, creating more trading opportunities.

(Overlap between London - New York )19h - 23h Vietnam Time###

This is the optimal time to trade forex. When the two largest markets in Europe and North America are active simultaneously, trading volume surges. Currency pairs involving USD and EUR—the two strongest currencies in the world—experience the highest demand. Price movements during this period tend to follow clear patterns, providing ideal conditions for trend traders.

(Overlap between Sydney - Tokyo )6h - 13h Vietnam Time###

This period marks the start of the trading day as Asian traders begin their activities. Although the volume is not as high as the London-New York session, there are still interesting opportunities, especially with Yen-related pairs (JPY) such as EUR/JPY and GBP/JPY—these pairs tend to have notable volatility.

(Overlap between Tokyo - London )13h - 14h Vietnam Time###

This brief overlap lasts about 1 hour, as the Asian session closes and the European session begins. Price volatility is generally low during this time, but currency pairs with JPY may still show some movements.

Days of the Week Affecting Forex Trading Hours

Not every day of the week is suitable for forex trading. The market experiences significant changes depending on the day:

Monday: The market is usually quiet unless important economic news is released. Price volatility is about half of that on midweek days.

Tuesday, Wednesday, Thursday: These are the “golden” days for trading, with the most active market movements. Economic news releases often create good trading opportunities.

Friday: During the first half of the day, the market remains active, but after midday, trading volume decreases as traders close positions in preparation for the weekend. This reduces profit opportunities.

Optimal Trading Hours Strategy

To achieve the best results in forex trading:

Prioritize the London - New York session in Vietnam evening (19h - 23h), when volatility is highest and profit opportunities are greatest.
Focus on Tuesday to Thursday, when the market is most lively and economic news is frequently released.
Trade major currency pairs like EUR/USD, GBP/USD, USD/JPY during the London-New York sessions to leverage high trading volume.
Avoid early Monday or late Friday trading when the market is quieter, unless there are significant economic news releases.

Understanding forex trading hours and sessions will help you maximize profit opportunities and manage risks more effectively.
