Put/call ratio by exchange
| Exchange | Calls OI | Puts OI | OI put/call | Share | Calls 24 h | Puts 24 h | Volume P/C |
|---|---|---|---|---|---|---|---|
| Deribit | 247,420 | 146,623 | 0.59 | 88 % | 9,896 | 8,093 | 0.82 |
| OKX | 14,828 | 19,037 | 1.28 | 8 % | 3,274 | 4,256 | 1.30 |
| Bybit | 8,869 | 12,074 | 1.36 | 5 % | 5,653 | 6,404 | 1.13 |
Deribit holds most of the open interest, so it sets the combined figure; OKX and Bybit often lean differently. An exchange marked "small" has under 1 % of the open interest, so its ratio says little.
Put/call ratio over time
Our own record, one snapshot every 15 minutes since 26 October 2026 (39 hours). Over this period the open interest put/call ratio ranged from 0.65 to 0.67, median 0.66.
How to read the put/call ratio
- Compare the ratio with its own history and between expiries rather than with a fixed number.
- A put/call ratio counts contracts, not direction: every option has a buyer and a seller. Who holds them is not public.
- Daily expiries are small and jump around; the monthly and quarterly expiries carry the weight.
- Volume put/call shows today's flow; open interest put/call shows the positions that are still open.
This page describes positioning. It is not a forecast, a signal or financial advice.
How the numbers are calculated
- Take open interest for every Bitcoin option on Deribit, OKX and Bybit, in BTC.
- Add up calls and puts for each expiry, for each exchange and for all expiries together. Expiries that have already settled are left out.
- Put/call ratio = puts ÷ calls.
- Volume put/call: every option trade on the three exchanges over the last 24 hours, BTC of puts ÷ BTC of calls.

FAQ
What is the Bitcoin put/call ratio today?
The Bitcoin put/call ratio is 0.66 by open interest (28 October 2026, 08:50 UTC): 177,733 BTC in open puts against 271,117 BTC in open calls, all expiries on Deribit, OKX and Bybit added together. Over the last 24 hours, 18,753 BTC of puts and 18,823 BTC of calls traded, a volume put/call ratio of 1.00.
How is the put/call ratio calculated?
Open interest put/call ratio = open interest in puts divided by open interest in calls, counted in BTC of underlying. Volume put/call ratio = BTC of puts traded divided by BTC of calls traded over the last 24 hours. We add Deribit, OKX and Bybit together and also show each exchange and each expiry on its own.
What does a high or low put/call ratio mean?
Above 1 means more puts than calls are open; below 1 means more calls. It counts positions, not who bought or sold them: a put can be a hedge bought by a holder or an income trade sold by someone collecting premium, so a high ratio is not automatically bearish. It is most useful compared with its own history and across expiries. It is descriptive data, not a signal or advice.
What is the difference between open interest and volume put/call ratio?
Open interest counts every option still open, so it changes slowly and shows how the market is positioned. Volume counts what traded in the last 24 hours, so it reacts to today's flow and can swing a lot, especially around an expiry.
Why is the put/call ratio different on other sites?
Many sites show Deribit only, or one expiry, or volume instead of open interest. Deribit holds most Bitcoin options, but OKX and Bybit often lean differently, so the combined figure here can differ from a Deribit-only number. The table by exchange shows each one.
Where can I see the put/call ratio for Delta Exchange India?
