Reading these numbers
- PCR 0.572 — put OI ÷ call OI summed across every Deribit expiry. Crypto tends to run lower PCR than Indian indices.
- Max pain $69,000 — aggregate strike minimizing writer payout if all expiries settled there (they don't — daily/weekly/monthly roll separately).
- Liquidations — real forced closes from Deribit, OKX and Bybit only; not Binance market-wide.
