Two tools  ·  one lens

Read the structure the
market hides in plain sight.

FlowRadar turns two public but hard-to-read data sets — options dealer positioning and SEC microcap filings — into terminals you can actually work from. Transparent inputs, direction-neutral output.

Educational & informational · Not investment advice

Two products

Two ways to read structure — buy one, or both.

Options dealer positioning and SEC microcap filings are two very different data sets. Each gets its own terminal. Take the one that fits how you trade, or bundle both.

Options · $59/mo

Options Flow & Gamma

Where dealer hedging bends price. The gamma terminal on every ticker, plus a market-wide scanner for unusual options activity.

Gamma mapCall wall, put wall, zero-gamma flip and net GEX on any ticker.

Microcap Radar · $39/mo

Microcap Radar

Structurally combustible microcaps, ranked. A transparent five-pillar score over the disclosed conditions behind violent moves — in either direction.

The boardUS-listed operating microcaps ($1–5), ranked by susceptibility.
Five pillarsDilution, cash runway, float, setup markers, volatility.
Per nameShort interest, days-to-cover and a per-name SEC dossier.

Options — two layers, one view

Flow tells you what happened. Gamma tells you what it means.

Most alert feeds show you the print and stop there. FlowRadar keeps the two layers side by side, so every flagged trade carries the positioning context around it.

Layer 01 — Unusual activity

What we flag

Signals that separate genuinely unusual prints from ordinary chain churn.

Relative volContract volume scored against that contract’s own median — unusual is always relative.
SweepsAggressive orders taken across multiple exchanges to fill fast.
PremiumOutsized dollar notional on a single strike or expiry.
BlocksSingle large prints, with the traded price shown alongside.
Net premiumDirectional premium balance over a window — inferred, not stated by the tape.
Layer 02 — Gamma exposure

Where it lands

The dealer-positioning map that turns a print into a location on the board.

Call wallStrike with the heaviest positive gamma — where rallies tend to stall.
Put wallHeaviest negative gamma below spot — where selling tends to slow.
Zero-gamma flipThe pivot between pinning and trending behaviour.
RegimeLong-gamma (mean-revert) vs short-gamma (trend) at a glance.
ProfileNet GEX across the whole chain, front and next expiry.
Microcap Radar — structure over story

Structure decides how far a small-cap can move.

A microcap’s next move is shaped by what it has already disclosed — how much stock it can issue, how long its cash lasts, how tight its float is. Microcap Radar scores those conditions from SEC EDGAR and market data, and never predicts a direction.

The score — five pillars

What it scores

Every rank breaks down into named, individually-scored pillars — subscribers see the exact contribution of each. Nothing is a black box.

DilutionAuthorized-vs-outstanding headroom, shelves and convertibles — capacity to issue.
CashBurn against cash on hand — runway before financing pressure.
FloatFree float, short interest and days-to-cover — how tight the tradable supply is.
SetupReverse splits, bid deficiency, rebrands — disclosed structural markers.
VolatilityHistorical realized volatility — how violently it has moved before.
The signals

What it surfaces

The disclosed conditions behind violent moves, pulled straight from the filings.

Short interestConsolidated short interest and days-to-cover, per name.
Reverse splitExecuted or proposed splits, flagged from recent filings.
Going concernAuditor substantial-doubt language, lifted from the latest filing.
Active shelfS-3 or a recent 424B5 — registered capacity to sell stock.
Listing riskBid-price and listing-deficiency notices.
Built to teach, not just alert

Every term, in plain language.

FlowRadar ships with the vocabulary built in. The education library defines every term with a worked example — so newer traders learn the map alongside the data, not after it.

Gamma wall

A strike where dealer gamma is concentrated enough to act like magnetic support or resistance.

Zero-gamma flip

The price level where net dealer gamma crosses zero and hedging behaviour reverses.

Dilution headroom

Authorized shares minus those outstanding — how much new stock a company can issue before asking for more.

Cash runway

Cash on hand divided by burn — how many months before a microcap likely needs to raise.

Short gamma

Dealers hedge with the move, which tends to amplify trends and volatility.

Days-to-cover

Short interest divided by average volume — how long it would take shorts to buy back in.

Notional premium

The total dollars committed to a trade — size that ordinary flow rarely reaches.

Going concern

Auditor language flagging substantial doubt a company can continue operating — a disclosed structural risk.

Signal over noise

Structure you can see the reasoning behind.

01

Pull the source

Options chains across every listed strike and expiry; SEC EDGAR filings for every operating microcap.

02

Baseline each name

Measured against its own history and its own disclosures — unusual and combustible are both relative.

03

Score the exposure

Black-Scholes gamma builds the net-GEX profile; five weighted pillars build the microcap susceptibility score.

04

Show the parts

Flow lands on the gamma map; every rank breaks into named pillars. You see context, never a lone number.

A block at the call wall reads differently than the same block below the flip.
That distinction is the whole idea, on both boards. FlowRadar is built so you never have to piece the layers together by hand — under a live tape, or across a stack of filings.
