BTC 24-hour one-sided decline of 5.24%, open interest rises 8% against the trend

BTC-USDT-SWAP fell 5.24% cumulatively from 03:00 Beijing time on 10-30 to 03:00 on 10-31, closing from 80833.5 to 76598.1, with an intraday low of 76260; hourly volatility was modest throughout, forming a sustained one-sided move. This kind of price action is the least friendly to chasing rallies or selling breakdowns—catching longs midway makes it easy to get slowly ground out of stops. Across the whole market, perpetual open interest rose 8.00% in 24 hours to 3.701 billion USD; price fell while open interest rose, indicating both longs and shorts are adding positions, and once volatility expands, the risk of wicks and cascading liquidations will rise in tandem; the current funding rate is 0.0100%, and holding costs still need to be factored into P&L. Look at the cycle and direction first, then discuss entry; position sizing and stop-loss discipline come first—if it's unclear, take a break.
