That day's view: The second trading day after the September 17 FOMC meeting, BTC opened at 76417.01 and closed at 80883.87, with a high of 81400.00 and low of 76296.00, surging 5.85% with a strong break above the 80000 neckline and the 81400 previous high, presenting an explosive unilateral upward pattern. Trading volume was 23,908 coins, an increase of approximately 118.8% compared to September 17's 10,925 coins. The price-volume rise confirms that dovish FOMC interpretations have been fully priced in. Funding rate at +0.00729%, essentially flat compared to September 17's +0.00723%. The positive range has held for three consecutive days without a flip, indicating neutral short-term funding costs and no tight multi-position competition. Open interest slightly decreased from 108,245 to 107,939 contracts, a decline of 0.28%. Price appreciation accompanied by marginal open interest decline, with retail long/short ratio dropping from 1.45 to 0.90 at close and large account ratio falling from 1.52 to 0.98, signaling increased selling pressure and large holder position reduction. Fear & Greed Index at 56, up 6 points from September 17's 50, sentiment recovered from neutral to mild greed. Comprehensive assessment: (c) short covering rebound. Follow-up derivative buying from FOMC has not formed sustained follow-through. Key resistance at 81400 level, support watching the 76000 round number. Monitor Fed successor Chair Warsh's first public remarks, second dot plot interpretation, and September 19 initial jobless claims for latest guidance on rate cut path.
