The percentage increase brought by the index effect will bring a larger range of fluctuations when it falls. Will the new high not be dumped, and wait for a bigger fall before it is released?

There is no eternal abundance, nor eternal emptiness. Both the house and the retail investors will close out when the floating profit is sufficient. And the house will quickly change positions between long and short. Don't play with small price differences within 1000 points anymore, the era of large rise and fall values has arrived. Seizing the opportunity can turn things around.
