- 1. btc bearish flow
- 2. eth heavy puts
- 3. btc bearish repeat
- 4. eth bearish deepens
- 5. btc flips neutral
five options flow signals surfaced on june 27. all from deribit. all disappeared. four bearish, one barely bullish. the pattern is the story.
1. btc bearish flow
$BTC, deribit, cex. options flow signal. realistic apy 200%. capital range $25k to $10m. 1x leverage. last 90min flow showed $16.96m calls vs $17.91m puts, a bias of negative 0.03. 27 block trades over $250k notional. max-pain proxy at $64,000 while spot sat at $60,235. dealer-gamma framework: put dominance creates a downside vacuum, pulling spot away from the max-pain level. risks: block trades may be hedges, not directional bets. interpret in context with spot/perp positioning. open interest gamma skew positive 0.26.
2. eth heavy puts
$ETH, deribit, cex. options flow signal. realistic apy 200%. capital range $25k to $10m. 1x leverage. flow was decisively bearish. $1.46m calls vs $8.76m puts, bias negative 0.72. 10 block trades. max-pain proxy $1,800 vs spot $1,579. the put dominance was not subtle. dealer-gamma framework suggests a downside vacuum with spot well below the strike cluster. risks: block trades may be hedges, not directional bets. interpret in context with spot/perp positioning. open interest gamma skew positive 0.27.
3. btc bearish repeat
$BTC, deribit, cex. options flow signal. realistic apy 200%. capital range $25k to $10m. 1x leverage. an hour later, the same story. $5.09m calls vs $6.19m puts, bias negative 0.10. 17 block trades. max-pain proxy still $64,000 vs spot $60,138. the gap between max-pain and spot persisted. put flow continued to dominate. risks: block trades may be hedges, not directional bets. interpret in context with spot/perp positioning. open interest gamma skew positive 0.26.
4. eth bearish deepens
$ETH, deribit, cex. options flow signal. realistic apy 200%. capital range $25k to $10m. 1x leverage. bias deepened to negative 0.83. $481k calls vs $5.30m puts. only 6 block trades but the dollar skew was extreme. max-pain proxy $1,800 vs spot $1,577. confidence dipped to 0.87, likely due to the smaller trade count, but the direction was unambiguous. risks: block trades may be hedges, not directional bets. interpret in context with spot/perp positioning. open interest gamma skew positive 0.27.
5. btc flips neutral
$BTC, deribit, cex. options flow signal. realistic apy 200%. capital range $25k to $10m. 1x leverage. the final signal flipped. bias positive 0.01, flat. $2.85m calls vs $2.77m puts. 5 block trades. max-pain proxy $64,000 vs spot $60,178. confidence dropped to 0.51. the bearish pressure from earlier windows had dissipated. risks: block trades may be hedges, not directional bets. interpret in context with spot/perp positioning. open interest gamma skew positive 0.26.
the set tells a clean story. four consecutive bearish flow windows across btc and eth, with eth showing the strongest put skew. then a neutral btc print to close. max-pain proxies sat well above spot for both assets throughout, meaning the dealer-gamma framework pointed to a downside vacuum. the block trades may be hedges, but the consistency across assets and time windows is hard to ignore. no funding arb, no stablecoin yield, no perp trade. just flow.
