On the 1-hour chart, the MACD has formed a bearish crossover, with volume continuing to shrink; on the 4-hour chart, the MACD remains in the bullish zone, and the Bollinger Bands are gradually narrowing. The order book shows a short premium of 1.85%, funding rate at 0.01%, and overall sentiment is neutral.

The support zone between 71.34 and 71.78 has been tested multiple times under pressure, with buying orders continuously entering at lower levels.
Defense: If the 1-hour MACD declines with increasing volume, or the price quickly breaks below 71.3 without an effective rebound, the current bullish view will be invalidated.
Operations: Long in the 71.5-71.7 range, target 73.
