Why this is usually paid for

Options analytics are among the most expensive data in crypto. The raw quotes are public, but turning them into open interest by strike, a volatility surface or a gamma profile means normalising four venues that disagree on nearly every unit, and that work is usually sold as a professional subscription.

The disagreement is real and easy to get wrong. Deribit quotes Bitcoin premiums in Bitcoin and volatility in percent; Bybit quotes dollars and fractions; OKX splits its book into coin-margined and dollar-margined families; Binance quotes some contracts per hundred or per thousand coins while publishing open interest in coins. Basis converts each one at the edge and checked the result against the venues’ own published greeks.

Because the normalisation runs once on a cached server read that every visitor shares, there is no per-user cost to meter, and therefore nothing for a subscription to cover.

How to use it

1. 1

   Open the options workspace on All venues

   The button below opens the terminal directly on Options. All venues is the default: open interest, volume and gamma add up across the four exchanges, while every volatility figure is read from the venue with the most open interest, which the page names.

2. 2

   Start with volatility and skew

   Thirty-day at-the-money implied volatility says how much movement the market is paying for. The 25-delta risk reversal says which direction is paid for more: negative means puts are bid over calls, which is the usual state of crypto options and changes meaningfully when it flips.

3. 3

   Find where positioning is concentrated

   Open interest by strike shows the levels with the most contracts open, and the expiry chips show which dates carry the size. Large expiries close to spot are where hedging flows and pinning pressure concentrate as settlement approaches.

4. 4

   Drop into the chain when a level matters

   Choose an expiry and switch to Chain and strategy lab to read the contracts themselves, inspect one in detail, export the chain, or build the trade you are considering and see its payoff at expiry and under price, volatility and time scenarios.
