Select Data · Institutional market microdata

Exclusive, self-recorded market microdata.

Recorded live, tick by tick — not scraped, never backfilled. Point-by-point sports and crypto microstructure, captured forward-only and frozen at the moment it happened. Built for quants and researchers who need history they can trust.

Self-recorded CSV + Parquet Delivered on request

Independent data vendor. Datasets contain publicly observable market data, recorded independently.

01 · Live

Recorded, not scraped

Every record is a live capture, stamped with its ingestion time — not reassembled from an endpoint that only shows the present.

02 · Frozen

Point-in-time integrity

Forward-only capture. Nothing is revised, relabeled or “corrected” after the fact, so what you test on is what was really there.

03 · Honest

Gaps logged, never faked

Disconnects are written as explicit gap markers, never interpolated into a false continuity. Voided sessions stay in the archive.

Each dataset ships as CSV and Parquet with a documented, versioned schema. Coverage is ongoing — the field lists below are sample schemas; contact us for current record and session counts.

02 · Why recorded

Why recorded beats scraped

Scraped history is assembled after the fact from endpoints that only ever show the present. Recording captures the past as it actually happened — and that difference is the whole product.

Fidelity

Timestamp fidelity

Every record carries the capture time at ingestion (epoch milliseconds), not a re-derived or vendor-normalized clock. You see the book exactly as it stood, at the instant it stood there — the arrival order and latency structure a scrape flattens away.

Integrity

No backfill, ever

Recordings are forward-only. Nothing is reconstructed, revised or restated after capture. Scraped datasets silently inherit later corrections and re-labelings; a recording is frozen the moment it lands, so a study runs on the real past, not a cleaned-up version of it.

Population

Survivorship-bias immunity

Because capture is live, sessions later voided, abandoned or delisted stay in the archive exactly as they occurred. Scrapes of “current” endpoints quietly drop whatever no longer exists — the classic hidden bias. We keep the full population, disconnect gaps included and clearly marked.

03 · Custom

Custom recording — name the source, we record it

If it streams, we can capture it forward-only into the same canonical schema — sports, crypto, or any public real-time market feed. Tell us the venue, the markets and the fields you need; we scope the recording, start capturing, and deliver on your cadence in CSV and Parquet.

Recordings begin at commission. We do not sell history we did not capture, so a custom set accrues from day one — and it is yours to evaluate on a sample before you commit.
