When the market demand is high, the total amount of stock index futures also increases, which shows that investors are more interested in stock index futures trading. When the market demand gradually decreases, the total amount of stock index futures also begins to decline, which shows that investors gradually lose interest in stock index futures trading and the market liquidity is gradually insufficient.
