What is Bitcoin max pain?
Max pain is the expiry price at which option buyers, together, would lose the most, and option sellers would keep the most. It is worked out from the open interest at every strike. Some traders watch it as a magnet for Bitcoin into expiry, especially on quiet days. It is a tendency, not a rule.
- Worked out from call and put open interest at every strike.
- It is the settlement price that pays option holders the least.
- It shifts through the day as positions open and close.
- Bitcoin has an expiry every day, so there is a max pain every day.

Questions people ask
How is max pain calculated?
For each possible settlement price, add up what every open call and put would be worth at expiry. The price where that total is smallest is max pain.
Does Bitcoin always expire at max pain?
No. Some traders see the price drift toward it on quiet days, but a strong move or big news easily overrides it. Treat it as one input, not a forecast.
Is max pain useful for option selling?
Some sellers centre range trades, such as iron condors or strangles, around max pain and the OI walls. It works best alongside other levels, such as the expected move.
When is max pain most useful?
In the last hours before an expiry, on a day with no major news. Far from expiry, or when the market is reacting to an event, positioning has much less pull on the price.
Who benefits if Bitcoin settles at max pain?
Option sellers as a group, because that is where the options they sold pay out the least. Option buyers as a group lose the most premium there, which is where the name comes from.
Is max pain the same for every expiry?
No. It is worked out separately from the open interest of each expiry, so today's daily, this Friday's weekly and the monthly can all have different max pain levels at the same moment.
Max pain, worked on three strikes
An example small enough to do by hand. Three strikes are open: the 79,000 put with 100 contracts, the 80,000 call and put with 50 each, and the 81,000 call with 100.
If Bitcoin settles at 79,000, the calls are worthless and the 80,000 puts pay 1,000 each: 50 × 1,000 = 50,000 to option holders. If it settles at 81,000, the puts are worthless and the 80,000 calls pay 1,000 each: again 50,000. If it settles at 80,000, every option on the board expires worthless and holders receive nothing.
Max pain is the settlement price with the smallest total payout, so here it is 80,000. A real chain has dozens of strikes, but the sum is the same: for each possible settlement price, add up what every open call and put would pay, and take the lowest.
| If Bitcoin settles at | Calls pay | Puts pay | Total to holders |
|---|---|---|---|
| 79,000 | 0 | 50,000 | 50,000 |
| 80,000 | 0 | 0 | 0 (max pain) |
| 81,000 | 50,000 | 0 | 50,000 |
What our own records show
Algoclear has checked this on its own stored data. Across 42 daily expiries in Bitcoin, Ethereum and Gold, the price ended nearer to max pain than it had been four to six hours earlier on 29 of them, about 69%.
Read that with care. It is a small sample from one stretch of market, and drifting toward a level is not the same as settling on it. It supports watching max pain on quiet expiry days; it does not make it a forecast.
How traders use max pain
Always beside other levels, never alone.
- As the centre of a range trade on a quiet expiry day: an iron condor or an iron butterfly built around it.
- With the open-interest walls: max pain usually sits between them, and the three together outline the range sellers are defending.
- Against the expected move: if max pain is further away than the market expects Bitcoin to travel, it is unlikely to matter today.
- Watching how it shifts. Max pain that keeps moving with the price is following, not leading.
Why max pain exists
Option sellers, often market makers, hold large books of options and hedge them as the price moves. Near expiry, that hedging can nudge the price toward the strikes where most open options expire worthless. That is the idea behind max pain.
A fresh max pain every day
Bitcoin options on Delta Exchange India settle every day at 5:30 pm India time, so there is a new max pain level every day. Algoclear's Market now shows it beside the OI walls and the expected move for Bitcoin, Ethereum and Gold.
Common mistakes with max pain
Most come from asking too much of it.
- Trading it as a price target. It is a tendency seen on quiet days, and news overrides it easily.
- Using this morning's level this evening. It is recalculated as positions open and close.
- Applying the weekly's max pain to today's expiry. Each expiry has its own.
- Ignoring size. On a thinly traded expiry, a few contracts can move max pain a long way.
