How to Read Max Pain
Compare pin-risk and strike-pressure across expirations from the latest published close.
What max pain measures

Max pain is the strike where option holders would collectively lose the most at expiration, based on open interest across the listed chain.

How traders use it

It is most useful as a possible pinning zone, especially when spot is already trading near a crowded strike into expiration.

What can break it

Strong directional flows, news, or fast spot moves can overwhelm any pinning tendency, so max pain should support a thesis rather than drive it alone.

The closer you are to expiration, the more useful this becomes as context and the less useful it is as a standalone prediction.
