Plummeting from the highest point by 10,000 points, the lowest spike at 92,500 is 1,000 points away from the previous 91,500, and it is still in the declining B wave.

In the short term on the 4-hour chart, the rebound pressure is between 97,600 and 98,600. If the rebound cannot reclaim these key pressures, it cannot be ruled out that there will be another test of the support line at 91,500, which carries a risk of breaking.
