Four hours of continuous two large bullish candles, Bollinger Bands opening significantly. Currently breaking above the previous high of 89,500, with further upward target around 90,500. After a sharp rise in the morning, a correction wave is expected, watch for resistance above, and wait for a suitable entry point to short again. Additionally, MACD shows weak bullish momentum, with a lack of rebound volume, making trend breakthroughs difficult; the 4-hour BOLL is narrowing, indicating continued consolidation. In summary, BTC trading should mainly focus on buying on dips at lower levels.
