Although the overall trend retreated yesterday, the main trend structure remains in the bullish zone, without breaking key support levels. The long-term bottom has not collapsed at all; it's just that the high-level surge can't move forward and is taking a break to walk waves and adjust. Currently, the bulls' strength is clearly falling behind, with resistance at 82,000-82,500 firmly blocking the way. The 4-hour chart has directly turned weak, showing a pullback, with indicators weakening and facing obvious resistance. 80,800 has become a short-term ceiling; if it can't break through, it will likely continue to oscillate downward. The important support lines are at 79,500 and 79,000. This wave of pullback is expected to stop around this area. The 1-hour chart shows only a small rebound after the decline; it looks like a warming-up, but there's not much momentum. Once it hits 80,500-80,800, it will likely turn back down. Key intra-day trading points to remember: resistance at 80,800 and 81,800; support at 79,500-79,000. Currently, the outlook is long-term bullish with short-term consolidation. As long as 79,000 is held, there is still a chance for a rebound. For now, stay neutral or only trade ultra-short-term.
