Have a great influence. Price cage is one of the important indicators in the futures market, which is used to analyze and evaluate market risks, trends and predict future trends, and has great influence on futures. When the price cage is small or disappears, it shows that the market's expectation for the future is stable, and both buyers and sellers believe that the current and future supply and demand are basically balanced, and there will be no violent fluctuations. Traders are more willing to speculate to improve the liquidity and activity of the market. On the contrary, when the price cage is large, it shows that the market's expectations for the future are uncertain, and buyers and sellers believe that the current supply-demand relationship has changed and there is a greater risk of fluctuation. Traders are generally cautious and tend to carry out arbitrage operations to avoid risks, resulting in a decline in market liquidity and a decrease in trading volume.
