A non-trading day refers to a day when financial markets are closed and trading activities cannot take place. Financial markets typically have designated trading hours and days during which buying and selling of financial instruments such as stocks, bonds, currencies, and commodities occur. On non-trading days, the markets are closed to investors, and no price movements or transactions occur.
Non-trading days often include weekends and public holidays when financial markets are officially closed. Additionally, there might be other specific non-trading days due to events such as market holidays or closures mandated by regulatory authorities. The closure of markets on non-trading days allows participants to take a break and serves administrative and regulatory purposes.
