· Options flow · Scanner

Big options bets leave footprints. Read them.

A scanner that prices every print in dollars, tags the whales and the unusual activity, and reduces the tape to one question: who is paying up — calls or puts? Explore it below on simulated data.

· What it is · How it works

Every print, classified — size, direction, freshness

01

The tape, in dollars

Every contract that traded is priced the same way: premium = mid × 100 × volume. A minimum-premium filter ($10K to $500K) cuts the retail noise before you read anything.

02

Tagged by thresholds, not opinions

WHALE ≥ $1M premium · BLOCK ≥ $500K · UNUSUAL Vol/OI ≥ 2 · SWEEP Vol/OI ≥ 0.8. The same print always gets the same tag — you learn the scale once, you read it forever.

03

Direction, weighted by dollars

Call premium versus put premium, weighted by conviction — delta, Vol/OI, size — into one sentiment read: Bullish, Bearish or Neutral. The headline number in the demo above.

The read that separates a bet from noise

Three states of the same options print. Volume far below open interest is position shuffling and a weak signal. Volume matching open interest is an aggressive sweep. Volume at twice open interest or more is fresh positioning — the scanner tags it unusual.

Options flow is one half of dealer positioning — the other half is What is GEX (Gamma Exposure)?, the theory companion to this scanner.

· Use it yourself

One read: who is paying up?

Move the slider to shift today's premium between calls and puts — the strike ladder deforms and the sentiment verdict flips at the same ±15% neutral band the scanner uses. This is the first read on every tape, before any strike-level detail.

Calls are taking the dollars: 62% of today's premium is upside bets. The tape leans bullish.For you: direction is only half the read — check Vol/OI next. Paid-up calls on fresh volume (Vol/OI ≥ 2) is conviction; on stale volume it is often hedging or closing.
· Is it worth it

The scanner does the counting. You do the reading.

The real scanner covers eight liquid US underlyings — QQQ, SPY, AAPL, NVDA, TSLA, MSFT, AMZN, META — refreshes every 90 seconds, and filters by side, tag and minimum premium. The data is CBOE delayed (~15 minutes): flow for context and positioning, not for scalping the next tick — we would rather tell you that here than after you pay. It is part of the PRO plan at $29/mo, next to GEX, volatility and the journal.

Frequently asked questions

Where does the options flow data come from?
CBOE delayed quotes — no broker account needed, roughly 15 minutes behind the live market. We state this before you pay: it is flow for context and positioning reads, not for scalping the next 15 seconds.
What do WHALE, UNUSUAL, BLOCK and SWEEP mean?
They are thresholds, not opinions. WHALE: at least $1M premium on one line. BLOCK: at least $500K. UNUSUAL: volume at least 2× open interest — more traded today than positions existed before. SWEEP: volume at least 0.8× open interest. The same print always gets the same tag.
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. The real scanner lives in the dashboard, refreshes every 90 seconds, and filters by symbol, side, tag and minimum premium.
Which symbols does the scanner cover?
QQQ, SPY, AAPL, NVDA, TSLA, MSFT, AMZN and META — the most liquid US options underlyings. The scanner is part of the PRO plan.
