Crypto Options: Max Pain, Put/Call and DVOL

Most crypto-native bitcoin and ether options trade on one exchange, Deribit, and they settle on a fixed timetable. That makes them easy to track and easy to misread. The desk reads three options numbers every morning: the expiries coming up with their max pain levels, the put/call ratio and DVOL. This lesson explains each, and what each cannot tell you.

Calls, puts and expiry

A call option gives its buyer the right to buy at a set price, the strike, until expiry. A put gives the right to sell at the strike. Buyers pay a premium up front; sellers collect it and take on the obligation.

Deribit options expire at 08:00 UTC. There are expiries most days, but Friday is the main one, and the last Friday of each month carries the monthly and quarterly contracts, which are usually much larger. The issue's Radar lists next Friday's expiry and the largest expiry within the next 30 days, with the dollar value of the options expiring.

Max pain

Max pain is the strike at which option buyers, taken together, would collect the least at expiry. To find it, you take every strike with open interest, work out what all the calls and puts would pay if price settled exactly there and pick the strike where that total payout is smallest.

Say most open calls sit at strikes above the current price and most open puts sit below it. If price settles between those two clusters, both sets of options expire worthless, so max pain lands in the middle. That is all max pain is: a summary of where open interest is stacked.

You will often read that price is "pulled" towards max pain into expiry, because option sellers hedge in ways that pin price near large strikes. Sometimes price does drift there. Often it does not, and a big move into expiry ignores max pain completely. The desk treats max pain as context about where options are concentrated, never as a target and never as a reason to take a trade. The issue gives the distance from spot to max pain so you can see how far apart they are without doing the arithmetic.

The put/call ratio

The put/call ratio in the issue is put open interest divided by call open interest. Above 1, there are more puts open than calls; below 1, more calls than puts.

It is tempting to read a high ratio as bearish, but puts are often bought as insurance by holders who are long the coin. A fund holding bitcoin and buying puts to protect it raises the ratio without being bearish at all. So the ratio is more useful as a change than as a level. A ratio that jumps over a few days says demand for protection is rising, whoever is buying it.

DVOL: how much movement is priced in

DVOL is Deribit's volatility index, published for bitcoin and ether. It measures the 30-day implied volatility priced into options, expressed as an annual percentage. In plain terms, it is how much movement option buyers are paying for.

A useful rule of thumb: divide DVOL by about 19 (the square root of 365) to get the size of a typical one-day move the options are pricing. Say DVOL is 40. That implies a typical daily move of roughly 2%. A DVOL of 80 implies roughly 4%.

Low DVOL means options are cheap and the market expects calm. Calm does not last forever, and a move out of a quiet market catches the traders who did not pay for protection. High DVOL means the market is braced for movement, usually after a shock. The issue shows DVOL with its change since yesterday and its percentile for the year, because a reading only means something against its own history.

How the desk uses options data

Options data never chooses a trade at the desk. The call or pass comes from chart structure and perp positioning. Options add context: a large expiry two days away is a reason to expect a choppy approach, and a very low DVOL is a reason to respect the chance of a sudden move in either direction. When a call is made, its stop and target are set in advance and graded in R on the record, whatever happens at expiry.

Key takeaways

• Deribit options expire at 08:00 UTC; the last Friday of the month carries the largest expiries.
• Max pain is the strike where option buyers would collect least: a summary of open interest, not a magnet.
• The put/call ratio is put open interest over call open interest, and is more useful as a change than a level.
• DVOL is 30-day implied volatility; divide by about 19 for the typical daily move it prices.
