Options pricing

Every large SPX order of the session, rebuilt from the tape as an ORDER rather than a print, beside the ladder you build a structure on. Finished sessions are free to read. What a plan buys is TODAY.

The structure tester itself is free against any session: a run over the archive spends LAB credits, and those are on the main pricing page.

SPX only, and that is not a backlog item: an order is placed against the MEASURED book, which is signed from the trade tape, and SPX is the only root that has one. The other hundred symbols have a five-minute chain book, which can price a ladder and cannot tell you who was the aggressor. Orders plans are separate from LIVE, LAB, GEO and DATASET, and cancelling one never touches another. Rebuilt from the public tape: not a trading signal and not investment advice.
