WHY SkewFlow
Read the flow, not a verdict on it
Flow without fake certainty
A large call is not automatically bullish. SkewFlow separates call/put composition from execution-based directional lean, and leaves prints that cannot be read unattributed rather than guessing.
Drill into what actually happened
Move from session activity to an interval, then expiry, strike and contract, down to the individual prints — and open any one of them.
Context, not just alerts
Contract activity, 0DTE concentration, historical sessions and the factors behind every SkewScore, beside the print that triggered them.
PROVENANCE
Observed. Inferred. Modelled. Never blurred together.
OBSERVED
Off the tape as printed: trade price, size, the bid and ask at execution, exchange, premium.
INFERRED
Read from how a print executed: directional lean from where it landed against the quote, detected sweeps, likely multi-leg structures. Labelled as inference wherever it appears.
MODELLED
Computed under stated assumptions: implied volatility, Greeks, and dealer positioning, which is in validation. Marked as modelled on the screen.
SAMPLE DATA · SYNTHETIC — NOT MARKET DATAINTERVAL FLOW
Find the interval that mattered. Then see exactly what made it up.
Premium bucketed through the session, so you can see when it accelerated — then open that interval by expiry, strike and contract, down to the prints underneath.
INTERVAL → EXPIRY → STRIKE → CONTRACT → PRINTS
SAMPLE DATA · SYNTHETIC — NOT MARKET DATATRADE DETAIL & SKEWSCORE
Every score should be explainable
SkewScore measures how far an order stands out from ordinary activity, and shows each part of the working.
- PREMIUM
- How much money the order carried.
- EXECUTION
- Where it printed against the quote — above the ask, at it, at mid, below the bid.
- SWEEP
- Whether it was one order swept across venues, reconstructed and labelled as inferred.
- SIZE
- The order against the contract's open interest where we hold it, or against its own recent volume where we do not.
- EXPIRY
- How close it is to expiring.
- STRUCTURE
- Whether it looks like one leg of a multi-leg position. The only part that can subtract.
Not a prediction. Not a recommendation. Not a measure of trade quality.

THE DIFFERENCE
What a flow tool usually does, and what we do instead
| THE USUAL APPROACH | SkewFlow |
|---|---|
| Bullish or bearish label on every print | Prints that cannot be read stay unattributed |
| Call-heavy read as bullish | Call/put composition kept apart from directional lean |
| A sweep shown as fact | Sweep reconstruction labelled as inferred |
| A score with no working | Every SkewScore component shown |
| Aggregates only | Expiry → strike → contract → print |
| Model output styled like a fact | Modelled figures marked as modelled |
