Options Positioning & Max Pain History / no guesswork hidden

Options positioning. With a paper trail.

Inspect user-owned open-interest snapshots, reproduce max-pain calculations, and compare history only when expiry, timestamp, and data rights align.

Positioning is evidence, not a price prediction.

Computed locally

Confirm data rights before importing a vendor snapshot

No licensed feed or public redistribution permission is configured. The production licensing gate remains closed regardless of this local acknowledgement.

Before you act

Written vendor rights for storage, display, redistribution, derived metrics, and retention must be reviewed before any production feed or public historical pages launch.
Open interest and volume are different measures. Snapshot completeness, observation time, adjusted contracts, multiplier changes, and stale data can invalidate comparisons.
The minimum can span an interval or extend beyond the observed strikes. A single reported candidate is not a unique predicted settlement price.

Calculation notes & limitations

At settlement S, call intrinsic payout is Σ max(S − K, 0) × call OI × multiplier. Put payout is Σ max(K − S, 0) × put OI × multiplier.

The sorted-strike calculation uses cumulative counts and strike-weighted sums, avoiding a quadratic scan. Zero-total-OI snapshots produce no max-pain result.

This implementation accepts only a single consistent contract multiplier and expiry per comparison. It does not infer exposure direction, dealer positioning, or market impact.

Saving is optional. Files and records never leave your browser through this app.

02 / Look under the hood

The method is part of the tool.

Use only data you are entitled to analyze. Record underlying, expiry, snapshot date, multiplier, and source, with duplicate-strike checks.

Sum intrinsic call and put payouts across strikes and identify the minimum among observed settlement strikes. Preserve ties and the no-open-interest state.

Compare only matching expiry snapshots. Keep volume separate from open interest, and never interpret max pain as a forecast.

03 / Know the boundaries

Evidence before certainty.

No production data ingestion or public redistribution is authorized by this application. Licensing, completeness, contract conventions, and timestamp verification are required.

These are reference sources, not evidence that example records have been verified. Imported records retain the source links you provide.
