There isn't much to add regarding the index. The key is whether the 1-minute level can form a third buy signal. If the third buy is confirmed, then Y3 will continue to break upward; if no third buy appears, the market will enter the Y4 correction phase. Even if it enters Y4, it can only be used for short-term high-probability buy low, sell high operations. Honestly, even if I were to participate in such short-term trades, I personally prefer to stick to medium-term positions without moving. Because frequent trading can easily be confused by market fluctuations. Traders who try to profit through clever tricks often end up being repeatedly educated by the larger trend. Instead of trading frequently, it's better to stay calm and observe, waiting for the Y5 trend to become fully clear before considering the next move.
