In forex trading, the Asian session refers to the time period during which the markets in Asia are open for trading. The Asian session typically starts at 6:00 PM EST and ends at 3:00 AM EST. During this time, the major financial centers in Asia, including Tokyo, Hong Kong, and Singapore, are open for trading, and market activity is often dominated by traders in these regions. The Asian session is known for its relatively low volatility compared to the other major trading sessions, such as the European and North American sessions. However, some currency pairs, such as the USD/JPY, may be more volatile during the Asian session due to the high trading volume in the Japanese yen. Forex traders may choose to trade during the Asian session if they prefer a less volatile trading environment or if they are looking to trade specific currency pairs that are more active during this time.
