A fren asked me, since I wasn't optimistic about the market, why did it fall again?

The size of the market movement depends on the real market situation. The market is dynamic; when the market remains in despair, it means more people will sell and short, which also indicates that bulls can establish more positions. The more positions are established, the larger the market movement will become, so after every disaster, there are often many big opportunities.
From the chart, it can be seen that the current round of bulls has been significantly building positions since August and has not stopped to date. The more goods the bulls consume, the more it rises. Just be patient and wait a little.
