Max Pain and Expiry Fridays: What Options Tell Perp Traders.

By CryptoTraders · Market Education · 2026-11-07

Bitcoin options are a market most perp traders never touch, and it still moves their positions. Billions of dollars in notional value settle every month, most of it on Deribit at 08:00 UTC (4 a.m. ET during daylight saving time) on the last Friday, with smaller weekly expiries every Friday at the same time. Knowing what settlement does to the tape around it explains moves that look random on a perp chart.

What max pain measures

Max pain is the strike price at which the largest total value of options would expire worthless, the price that would cost option buyers the most at settlement. It is calculated from open interest across every strike for a given expiry and shifts as positions change. Analytics sites publish it before each large expiry, and crypto media quote it whenever the notional is big.

Why price sometimes drifts toward it

The usual story says option sellers push price toward max pain. The more defensible explanation runs through hedging. Market makers who sell options hedge with futures and spot, and as expiry approaches, those hedges have to adjust more aggressively to small price changes near strikes with heavy open interest. When dealers are long options near the current price, their hedging tends to dampen moves, buying dips and selling rallies, which can pin price near a large strike into settlement. When dealers are short options there, the same hedging tends to amplify moves.

That is why max pain acts as a loose magnet on some expiries and does nothing on others. It describes where open interest sits. The hedging behavior around it decides whether that matters on the day.

Using expiry as a perp trader

Mark the dates. Monthly expiries, and especially the quarterly ones in March, June, September and December, carry the most open interest. Expect compression into settlement when price sits near a large strike, and watch for expansion once the hedges roll off. Some of the sharpest moves of a month begin in the hours after expiry, once price is released from the pin.

Look past the single max pain figure to the largest individual strikes. Heavy open interest at round numbers above and below price often marks the edges of the pre-expiry range. And treat max pain as context for timing, never as a price target. Plenty of expiries settle far from it when spot news is strong enough to overwhelm the hedging flows.

Options data is free to read on most analytics sites. Ten minutes with the expiry calendar and the open interest by strike on the Thursday before a monthly settlement is one of the cheapest edges in context a perp trader can add.
