Since the two attempts to break through the pressure of 72000 have not been successful, it has fallen from the upper rail to the lower rail, showing signs of breaking through the lower rail. The daily line has repeatedly approached the 66200 line for 4 days, and the trend has opened the channel of upward and downward movement again. Overnight, it quickly rebounded after probing below the support and aiming at the 65000 mark, with a focus on the major support near 61400 on the weekly line, forming a double top pattern. The market continues to oscillate back and forth within the box, experiencing many reversals during this period. When watching the market, it seems that the strength at that time is either rising or breaking the range, but when you chase after it, it's either the ceiling or the floor. Overall, it still oscillates within the range. The 4-hour level signal is weak, with a tendency to adjust the trend. The downward momentum may turn around step by step. Try to take both ends as much as possible. Entering the middle position does not hold much space, wait for more signals!
