After the 108400 high point plunder, there was a wave of selling that caused a position swap at 106000, becoming the key point of these two days.

1. Maintaining above 106 will continue to oscillate or rise.

2. Falling below 106 is seen as the end of the rebound, increasing the probability of testing 104 and 102.

Support and resistance situation:

Upper resistance: 108400, 110000

Lower support: 106000, 104200, 102600
