From a technical perspective, the long black candle at the high directly engulfed the previous gains, indicating that bullish momentum is exhausted and selling pressure is being released concentratedly; subsequently, the price broke below the key support zone of 665-670, and the short-term uptrend is completely broken. Although there was a minor rebound today, it remained under pressure below 660, with weak rebound strength. The subsequent trend will likely continue downward, further testing support at 650 or even lower levels.
