Put/call balance by expiry
How many puts remain open for each call?
The put/call ratio compares the underlying coin amount in outstanding puts with that in outstanding calls, separately for each expiry.
For example, 1.5× means 150 BTC of puts for every 100 BTC of calls. A value above 1 means more puts remain open. It does not identify buyers or their motives: puts may hedge coins someone already owns.
Put open interest divided by call open interest. No open calls means the ratio is unavailable, not zero. The dashed reference at 1× means equal put and call exposure.
