Afternoon sideways consolidation and accumulation, the low point drops to, the bulls start to buy in, smoothly pushing up to the high of 77,317, nearly a 700-point increase. But after 16:00, resistance appears above, with clear upper band suppression, beginning to oscillate and fall back. After 17:00, the bears gain strength, with a rapid plunge at the end of the session, directly dropping to around 76,700, almost giving back more than half of the afternoon's gains. Now the price has fallen below the lower band of 76,740, with the bears dominating in the short term. Focus on whether 76,600 can hold.
