BTC's 82000 Call Dumped by Sellers While 85000 Call Absorbs the Buying

The Nov-6 82000 call is the chain's single largest call wall (5,474 contracts OI, 6.4% above spot) — a structural fact that alone would read as bullish positioning. But the taker tape flips that read: over the last 24h this strike was almost entirely sold.

Strike	Buy Vol	Sell Vol	Buyer Aggression	Blocks	Net Premium (24h)
82000C	123.5	4925.0	0.035	5	-$1.69M
85000C	4936.3	71.2	0.988	3	+$888k

The sell pressure concentrated in a single 4-hour window (12:00-16:00 UTC, Oct 30), flagged with block trades, while the 85000 call absorbed near-mirror buying in size and timing — consistent with a position rolled up a strike rather than two unrelated flows. OI-delta data for this expiry isn't available yet (too young for a 24h reference), so the wall size reflects resting OI, not fresh conviction.

Context: max pain for the expiry sits at 80000, gamma flip at 75,613, and the gex-weighted centroid at 80,214 — all below the 82000 strike that just got sold into, with spot at 77,046.
