Max pain gets a lot of attention on social media, usually with the claim that the market is "pinned" there. The truth is more useful than the myth.

The definition

Max pain is the expiration price at which the total value of all open calls and puts is the lowest. In other words, it is where option buyers as a group would lose the most money if the market settled there.

Why it can pull price

Max pain matters most when it lines up with large open interest close to price. As expiration gets near, dealer hedging around those big strikes can keep price contained, and price may drift toward the area where most options expire worthless.

Why it often does not

• It is a snapshot of open interest, not of live flows.

• It says nothing about new positions opened today.

• On trend days, macro news and real buying or selling overwhelm it easily.

How we use it

We treat max pain as context on expiration days, especially monthly OPEX. If price is far from max pain and momentum is fading in the afternoon, a drift toward it is a reasonable scenario. We do not trade it as a level on its own.
