Quick answers

Does SPY pin at max pain on expiration?

Not measured yet: 2 finalized sessions in the archive (2026-09-25 – 2026-09-28, latest 2026-09-28); 0 of 2 sessions closed within $0.50 of 0DTE max pain. No rate is published until 5 sessions; the counts and every dated session page are public from the first session.

What counts as a pin here?

We don't pick one threshold. The table counts the sessions inside several fixed distances so you can apply your own. Distances are measured from the official close to the 0DTE max-pain strike computed from 15-min delayed CBOE open interest at the close.

Why is every pin number approximate, including yours?

Open interest is published once a day, quotes are 15-minute delayed, and "max pain" is a model with choices in it (which contracts, which OI). We disclose ours on the methodology page and publish every session so you can recompute.
