According to the pattern, assuming 71800 is the top, the next target should be between 63850 and 65000 (Figure 1); if a Z-wave breakout occurs, the resistance is between 76-77 (Figure 2)). If it drops, observe the support at 63850—65000 and the rebound strength. If it's a weak rebound, then a real decline may be coming. If it's a strong rebound and pushes above 618, then the oscillation range will expand;
