What you want to ask is which is better before and after the futures market? Good before serving. Pre-trading and post-trading in the futures market are two different concepts. Before trading refers to the trading before the opening of the exchange, and after trading refers to the trading after the closing of the exchange. In pre-market trading, investors can observe the market dynamics, political and economic situation and industry changes at home and abroad. The futures market fluctuates greatly and the price changes rapidly. Before entering the market, they need to do sufficient market analysis and research to determine the timing and price of entering the market.
