That day's trend: Neutral leaning bullish

That day's view: Yesterday BTC closed at $81,249.99, with intraday high of $81,951 and low of $80,844, gaining 0.45% for the day. After the strong bullish candle on 9/18, price is consolidating in a narrow range at high levels. Volume at 10,664 BTC was significantly below the 7-day average by -26.7%, Funding rate averaging +0.00916%, continuing positive momentum with a 1.26x increase from 9/18's +0.00729%. Open interest declined slightly from 107,939 to 107,646, down -0.27%. With institutional long/short ratio holding elevated at 2.07, retail slightly bullish at end, and active buying returning in late session, assessed as (c) short-covering rebound continuing - volume contraction signals temporary pause in upward momentum but trend intact. Fear & Greed Index surged from 56 to 71, jumping 15 points back into greedy/overheating territory, warning of potential short-term sentiment exhaustion. Key support zones at 80,844-81,000, resistance at 81,951 previous high. Focus on 9/25 BTC September options expiry (Deribit ~40B USD notional value) and whether macro landscape provides catalysts for second rate cut expectations this week.
