Options flow: the orders that are
too big to hide.
Read options activity alongside its source, timestamp and classification method. Size filters identify observations to investigate; they do not establish who traded or why. In the app, NQ and MNQ options arrive from the CME through Rithmic with the aggressor side published.

Explore the tape
v0.88.1 of the app, on a simulated NQ options session.
The app’s option flow, v0.88.1, on generated prints: orders by premium and aggressor side, the largest and the most unusual. Click the screen to use it; move the pointer away and the page scrolls again.
Read the tape
Each print with its premium, side and source.
- Tape and pressurePrints as they come, and premium pressure by side.
- Strike map, by strikeWhere the activity sits on the chain.
- Blocks and new positionsLarge prints, and volume above open interest. A missing open interest is shown as unknown, never as a new position.
- Unusual and alertsPremium far above what that strike usually trades, and your own alerts.
The side, stated
Never mixed.
- PublishedThe source gives the aggressor side, as the CME does for NQ options through Rithmic.
- InferredDeduced by the app when the source does not publish it, and labelled as inferred.
- AbsentNo side is shown when there is none.
Limits, said
Before you read too much into a print.
- 500 printsThe tape keeps the most recent 500 prints; premium drift on Pressure counts every print since the open.
- Snapshots are not tradesSnapshot sources show volume changes, not individual transactions.
- Sweep labelsA volume ratio cannot verify a multi-venue sweep; check venue and execution coverage.

Questions
The same list feeds the page and its structured data.
Where does the options flow data come from?
From the source you configure in the app: NQ and MNQ options from the CME through your Rithmic login, with the aggressor side published by the exchange; ThetaData, Tradier, Alpaca or Databento with your key; or BTC and ETH options from Deribit for personal use. Snapshot sources show volume changes, not individual trades, and the screen says which kind you are reading.
What do WHALE, UNUSUAL, BLOCK and SWEEP mean?
They are scanner thresholds, not proof of identity or intent. Volume/open-interest ratios flag relative activity; they cannot alone verify multi-venue sweeps, opening positions or institutional participation. Inspect the source methodology and timestamp.
Is the flow on this page live?
No — this page runs on simulated data with a DEMO symbol so you can explore the interface freely. In the app, Option Flow has eleven pages, from the tape to the method, and keeps the most recent 500 prints: it is a window, not the whole session.
Which symbols does the scanner cover?
The underlyings your source covers: US equity and ETF options such as SPY and QQQ from ThetaData, Tradier, Alpaca or Databento, NQ and MNQ options from the CME, and BTC and ETH from Deribit. It is part of the one plan at $29 a month.
