From a technical perspective, the high-position long bearish candlestick directly engulfed the previous gains, indicating exhaustion of bullish momentum and concentrated release of selling pressure; subsequently, the price broke below the key resistance zone of 665-670, completely breaking the short-term uptrend. Although there was a slight rebound today, it remained under pressure below 660 with weak rebound strength. The subsequent trend will likely continue downward, further testing 650 and even lower support levels.
