Options Max Pain Explained: Reading BTC & ETH Max Pain

Why Price Sometimes Gravitates to a Strike at Expiry

Traders who watch crypto options expiries notice a recurring pattern: as a big BTC or ETH expiry approaches, price often drifts toward a particular strike and stalls there. That strike frequently turns out to be the max pain level — the price at which the largest number of option contracts expire worthless, inflicting the most collective “pain” on option buyers. It isn’t magic or manipulation; it’s a side effect of market makers hedging a large book of options into settlement.

The max pain calculator pulls live options open interest from Deribit for Bitcoin and Ethereum, lets you pick an expiry, and computes the max pain price along with the full strike-by-strike breakdown. This guide explains the theory and, more importantly, how to read the dashboard without over-trusting it.

How Max Pain Is Calculated

For a given expiry, every strike that currently carries open call or put interest is treated as a candidate settlement price. At each candidate, the calculator sums the dollar value option holders would collect if the underlying settled exactly there:

• In-the-money calls pay (settlement − strike) × open interest — for every strike below the candidate price.
• In-the-money puts pay (strike − settlement) × open interest — for every strike above the candidate price.

The max pain price is the strike where that total payout is smallest — where option buyers as a group would collect the least. It’s evaluated only at listed strikes, which is the standard convention. Intuitively, that’s the settlement level where the most premium stays in the sellers’ pockets. The logic runs the other way from the option buyer’s payoff: sellers (often market makers) profit most when the largest notional expires out of the money, and their delta hedging can gently pull price toward that level when the book is large and time is short.

Worked Example

Suppose one BTC expiry has open interest concentrated at four strikes. The calculator computes the aggregate payout (“pain”) at each candidate settlement:

Strike	Call OI	Put OI	Pain ($)
$90,000	1,200	400	$34.5M
$95,000	800	600	$25.5M
$100,000	500	900	$23.5M
$105,000	300	1,500	$28.5M

Walk the $100,000 row to see the arithmetic. The strikes below it are in-the-money calls: $90k contributes 1,200 × ($100k − $90k) = $12M, and $95k contributes 800 × $5k = $4M. The strike above it is an in-the-money put: $105k contributes 1,500 × $5k = $7.5M. Total pain = $23.5M — the lowest of the four. So max pain sits at $100,000. If two strikes ever tied, the lower strike wins by convention, so the reading stays deterministic.

How to Read the Max Pain Dashboard

This is a live dashboard rather than a manual calculator, so you read it rather than fill it in:

1. Choose the Asset — Bitcoin or Ethereum.
2. Choose the Expiry you want to study from the list of listed dates.
3. Read the headline Max Pain Price and compare it to the Current Underlying Price; the Distance to Max Pain tells you how far price would need to travel to reach it.
4. Check Total Call Open Interest vs. Total Put Open Interest to gauge whether positioning leans bullish or bearish, and read Days to Expiry — the pull toward max pain, when it happens at all, is strongest in the final hours.
5. Scan the per-strike table (Strike, Call OI, Put OI, Pain ($)) to see where open interest is concentrated and how sharply pain rises away from the max pain strike.

The dashboard refreshes from live Deribit data every 60 seconds, so the max pain strike can shift through the day as traders open and close positions. If an expiry shows no open interest, the tool tells you rather than inventing a number.

What Max Pain Is — and Isn’t

Be clear-eyed about this metric. Max pain is a positioning signal, not a prediction. It reflects only current open interest — not order flow, news, or momentum. Some traders watch it because price can drift toward it near expiry as market makers hedge delta on a large book, but large directional moves regularly overshoot it entirely. In a strong trend the underlying frequently settles far from the max pain strike. Use it as one input about where positioning is heavy, not as a target you trade blindly into.

Deribit is used specifically because it has historically carried the large majority of BTC and ETH options open interest, making its book the closest thing to a complete picture of positioning — a max pain reading from a thin-volume venue would mostly reflect noise. If you want to price the individual options behind that open interest, see the Black-Scholes pricing guide; to model a position’s payoff, the options profit calculator guide and the options strategy builder guide cover single-leg and multi-leg outcomes.
