To ensure fairness and liquidity in the market, as well as to consider the investors' need for rest and relaxation, the futures market will be closed during the Thanksgiving holiday. This allows investors to return to the market refreshed after the holiday and participate in trading with renewed vigor. The Thanksgiving holiday closure not only helps investors maintain their physical and mental well-being, but also avoids abnormal market波动.
