About this desk
- What you use it for
- Switch bitcoin or ether to see put and call open interest on Deribit, the put-to-call ratio, and the eight largest lines.
- What the numbers are
- Open interest is in the underlying coin, as Deribit reports it. The ratio is put open interest divided by call open interest. Mark IV is their number on that line. Day volume uses the dollar volume they publish.
- What it leaves out
- The eight lines are the largest by open interest, not every strike. Their dollar volume is the scale they publish, not a notional you should recompute. IV is not a forecast.
Every desk is introduced the same way on the desk list.
Calls hold 800,889 ETH. Puts hold 508,432 ETH, 0.63 puts per call. Day volume is $1.19M in calls and $4.05M in puts.

How to read this
- Open interest
- Deribit reports open interest in the underlying coin. This page adds every listed put and every listed call. It does not convert that into a bet on direction.
- Puts per call
- The ratio is put open interest divided by call open interest. Above 1 means more coin is sitting in puts than in calls. It is a stock of positions, not a count of people.
- Implied volatility
- Mark IV is Deribit’s own number on that line. A higher number means the option’s price implies a wider move. This page does not turn it into a forecast.
