How to read this

How to read this page

Each row is a single option contract our scanner flagged as unusual: volume far above the standing open interest (at least 2.5x and at least 500 contracts traded), with a real premium. Vol/OI is the ratio of today's volume to open interest: the higher it is, the more of the day's volume was fresh positioning rather than existing holdings. Premium is last price times volume, an approximation of the money that moved through the contract, not a settled tape total. Contracts are re-scanned about every 15 minutes during market hours; this page is the settled end-of-day record.

FAQ

What is unusual options activity?

Unusual options activity is a contract whose trading volume stands far above its open interest. We flag contracts with at least 2.5 times their open interest traded and at least 500 contracts of volume, which usually means fresh positioning rather than existing holdings changing hands.

How often is this page updated?

The scanner samples about every 15 minutes during US market hours. This page is the settled record for the trading day shown in the answer sentence at the top; each day gets its own archived page.

Is this live options data?

No. Everything here is a delayed snapshot derived from exchange options chain data. Nothing on this page is a live quote, and numbers are frozen at capture time.

Which tickers are tracked?

A core set of 55 liquid underlyings: the major index ETFs, mega-caps, and high-volume single names. The full list ships in the data pack linked in the provenance box.
