The current price has reached the daily level of 618 and has broken through the previous high point. The 5-minute-30-minute-4-hour structure is perfect and has formed a 5-minute-30-minute-4-hour level combination. The last view was on the eve of the plunge, because the high point has not been broken, the structure is not complete. This time, the view is that the plunge is imminent, the structure is complete and the levels are divergent. Today is May 2, Friday, and a new downward trend will be formed within three days. And if it falls below 91,600, it will go down directly. The new low of 74,466 will not be broken again. According to the time calculation, the 4-hour level downward segment will be completed around May 25, and the 4-hour level second buy will be formed after the decline ends, starting a new round of rise and breaking through the high point near 97,500.
