BTC's Aug-28 62000 Call Builds OI on Seller-Led Screen Flow, Not Buyer Demand
BTC's Aug-28 62000 call (strike ~0.7% above spot 61565.78) shows a +45.5 contract OI build over 24h, the fourth-largest net OI move in the chain. Read alone, rising call OI near spot often gets filed as bullish positioning. The tape says otherwise: over the past 72h takers sold $525,193 of premium against $234,758 bought at that strike, netting -$290,435 with buyer aggression at just 30.9%. Crucially, none of it came through blocks — 97 trades, zero block prints, pure screen flow.
Contrast that with neighboring strikes in the same expiry:
| Strike | 72h Net Premium | Buyer Aggression | Block Trades |
|---|---|---|---|
| 59000 C | +$1,552,673 | 96.8% | 3 |
| 60000 C | +$1,099,746 | 91.1% | 4 |
| 62000 C | -$290,435 | 30.9% | 0 |
| 65000 C | -$352,486 | 25.7% | 4 |
Strikes just below spot are getting bought aggressively via block-sized clips; 62000 is being written into strength on the open screen while OI still accumulates — a short-call-into-rally pattern rather than fresh directional long demand.
