On futures trial first and liquidation of Shanghai Futures Exchange.
At present, only the trading varieties of the Shanghai Stock Exchange can issue the order of "Closing Today" when closing positions. There is no "liquidation" instruction when the trading varieties of Dalian Stock Exchange, Zhengzhou Stock Exchange and China Financial Futures Exchange are closed, and the exchanges are settled according to the regulations after closing. Copper is the last variety, so what you pay today is today's order.
