After hitting the strongest suppression of the band this week for the first time during the day - around 67000 and 3650, the attempt to break through failed, and fell sharply again in the evening.

If the top is not broken, then continue to sell high and buy low around the range. In terms of thinking, the long orders of the band will continue to focus on 65K and 3530 to find entry opportunities. The subsequent rebound will still look at the high point suppression of the band range - 67000/3650.
