$BTC is currently trading at $81,632, down 1.9% over the past 24 hours. Price volatility in this move was concentrated in the two-hour window following the September CPI release.

Order book activity: Trading volume surged rapidly after 11:00 UTC, peaking at more than five times its previous level. The price retreated from $83,466 to $82,324, then fell to $81,641 and entered a narrow range. Hourly closing prices stayed between $81,587 and $82,013, a range of just $426.

Derivatives open interest signal: Open interest in perpetual contracts edged down 0.3%. With prices falling while open interest remained broadly flat, the selling pressure appears to have come from spot selling, rather than large-scale leveraged liquidations or new leveraged positions.

Market sentiment is clearly divided:

The segmented long/short ratio has continued to rise, as retail traders keep adding long positions during the downturn. However, immediate buy-order flow in the order book is weak: the hourly long/short ratio was below 1 in 6 of the past 8 hours, with the latest reading at 0.79. The funding rate is -0.0042%, suggesting market expectations for long and short positions are approaching neutral.

Trading data: Daily trading volume was $1.505 billion, 1.15 times the 30-day average. There were 354,343 trades, with overall trading volume remaining within its usual range.

On-chain network status: On-chain activity is subdued, with 8,320 transactions queued in the mempool. The network hash rate is 1,013 EH/s, and BTC's market dominance is 59.79%.

The current price is 6.6% below the 30-day high and 8.8% above the 30-day low ($74,968).

Summary: CPI data triggered spot selling and a short-term pullback, while derivatives leverage risk remains manageable. Market flows are clearly divided, and prices are likely to remain range-bound in the short term. Keep watching whether spot selling continues.

For market data observation only; this does not constitute investment advice. Markets are highly volatile.
