The trend of the large pancake today shows that the current rebound trend supports the range of 80500 to 80000. A pullback to this position can be used to close short positions or increase long positions, with a stop loss set at 80000. If it breaks below 80000, watch for 79000 and 78000. If the pullback does not break 80500, continue to look for a rebound with a resistance breakthrough at 82000, looking at strong resistance at 83000 to 83600, and 84000.
