Multi-venue

As of —

Deribit, Binance and Delta India read live, side by side — each venue's own spot, open interest and max pain, computed the same way for all three. Binance's public feed exposes open interest only, no bid/ask/premium, so its max pain and PCR are OI-based like the others but it has no premium column. Each venue's "daily"/"weekly" expiry is its own nearest listing — dates usually align but aren't guaranteed to. Deribit has no dedicated ETH spot feed wired, so its ETH spot is estimated from put-call parity across the chain rather than read directly — everything else is a direct feed read.

Delta India — for Indian residents. The only INR-settled book on this page. Expiries cut at 17:30 IST (12:00 UTC) — three and a half hours after Deribit's 13:30 IST cut — so "weekly" here and on Deribit are not the same moment even when the calendar date matches. OI is thinner than Deribit; use it to see local positioning, not global market share. Margin and compliance sit under India's FEMA frame, separate from offshore Deribit access.

How to read this page

Spot & basis — each venue's own spot price, and how far it sits from Deribit's (the reference venue, given its dominant open interest).
Open interest, PCR & max pain — computed the same way for all three venues, so the numbers are directly comparable.
Premium data availability — not every venue exposes the same depth of data (see methodology below); the table flags where a venue's numbers are OI-only.

Methodology & data

Deribit, Binance and Delta India are read live, with OI, PCR and max pain computed the same way on all three. Binance's public feed has open interest only, so no premium column. Each venue's daily/weekly expiry is its own nearest listing. Deribit's ETH spot is estimated from put-call parity; every other spot figure is a direct feed read.

Which exchanges does this page cover?

Deribit, Binance and Delta India — read live and compared side by side on spot, open interest, PCR and max pain.

Why do spot prices differ between venues?

Each exchange has its own order book and liquidity, so small price differences ("basis") between venues are normal and usually arbitraged away quickly. Persistent or widening basis can itself be a signal.

Why doesn't Binance show premium data?

Binance's public options feed only exposes open interest, not bid/ask/premium. Its PCR and max pain figures are still computed from open interest, same as the other venues, but there's no premium column for it.

Is Deribit's spot price direct or estimated?

Direct for BTC. For ETH, Deribit has no dedicated spot feed wired on our side, so ETH spot is estimated from put-call parity across the chain rather than read directly from an exchange feed.

What is Delta India and why is it on this page?

Delta Exchange India is the INR-regulated crypto-options venue for Indian residents. We include it because Deribit and Binance alone miss local positioning — same OI / PCR / max-pain read, but expiries cut at 17:30 IST and the book is smaller. Offshore Deribit access is a separate compliance question for residents.

Why do expiry cut times differ between venues?

Deribit settles at 08:00 UTC (13:30 IST). Delta India settles at 12:00 UTC (17:30 IST). Binance uses its own listing calendar. Comparing "weekly" across venues means checking the expiry code column, not assuming the same clock.
