The reason why the trading volume is large and falling is because the number of stocks sold is large and the number of stocks bought at the same time is large. This is a phenomenon caused by the inconsistent views between the long and short parties. Sellers believe that the market outlook will continue to fall, and buyers believe that the market outlook will continue to decline. The opportunity has come. But in the end, the sellers prevailed, thus forming this phenomenon.

Trading volume is a manifestation of supply and demand, which refers to the number of transactions for a certain transaction within a unit of time. When the supply exceeds the demand, there will be a huge crowd of people trying to buy, and the trading volume will naturally increase; on the contrary, when the supply exceeds the demand, the market will be deserted, and there will be little buying momentum, the trading volume will inevitably shrink. And digitizing the crowd is called trading volume. The broad sense of trading volume includes the number of shares traded, the amount of transactions, and the turnover rate; the narrow sense and the most commonly used one refers only to the number of shares traded.
