The report shows a bounded subset, not every qualifying contract.

Read the output

  1. 01volumeToOI = session contract volume ÷ standing open interest on the chain snapshot.
  2. 02relativeVolume versus that same contract’s recent daily volume when at least five prior snapshots exist.
  3. 03A ranked board with reader-tunable floors (vol/OI, rel vol, volume, OI, max DTE).

Keep in mind

It is not a live unusual-print tape. Live UOA still lives on Option Trades.

How to read it

From report to evidence

  1. 01

    Run the screener

    Open Unusual Options Activity Screener in Cookbooks. Tune vol/OI and relative-volume floors if the default board is too loud or too quiet.

  2. 02

    Read vol/OI first, then rel vol

    Vol/OI asks how large today is versus the standing book. Rel vol asks how large today is versus this contract’s own tape. A blank rel-vol cell means not enough history, not a zero.

  3. 03

    Handoff to the tape

    Anything you might trade still needs Option Trades and the chain. The recipe is the shortlist, not the fill.

Method and limitations

A paid Cookbook that ranks chain-snapshot contracts on volume/OI and, when history exists, relative volume versus that contract’s own recent daily volume. Thresholds are tunable. It does not name a trader or fire an alert. Official app template: Unusual Options Activity Screener.

What the report computes

  • volumeToOI = session contract volume ÷ standing open interest on the chain snapshot.
  • relativeVolume versus that same contract’s recent daily volume when at least five prior snapshots exist.
  • A ranked board with reader-tunable floors (vol/OI, rel vol, volume, OI, max DTE).

What it does not claim

  • It is not a live unusual-print tape. Live UOA still lives on Option Trades.
  • High volume/OI is not proof of a new whale, opening status, or a next-session move.
  • 0DTE is excluded. An EOD 0DTE print is a different job.

UOA here is configurable volumeToOI plus relative volume versus the same contract’s own history — concepts.md’s screening technique, not a baked “smart money” score.

Frequently asked questions

Is this the live UOA tape?
No. This is a completed-session chain screen. Live prints, sweeps, and filters stay on Option Trades.
Does a high volume/OI mean someone opened a position?
Not from this report. Volume/OI is a ratio. Rolls, hedges, and closing prints can all print the same number.
