The overnight 713 short position continues to be profitable, currently oscillating around 703. The four-hour chart failed to extend yesterday's rally and subsequently came under pressure, retreating with consecutive bearish candles indicating the short-term bounce has ended. The hourly Bollinger Bands are contracting with price rallying and then falling below the midline. The attached indicators are in resonance with the four-hour timeframe showing downward momentum, with insufficient bullish momentum in the short term. In the current oscillating market, upside space has been released, so chasing rallies is not advisable.

Maintain a high short bias in the afternoon session. Short-term resistance is in the 715-720 zone. If touched without breaking, go directly short. Aggressive traders can scale into shorts near 706 and 710. Downside targets are unified at the 690-680 zone.
