NOXINDEX How it works

Local-first market-data QA · Synthetic only

Stress-test market-data pipelines before feed faults become silent failures.

NOXINDEX generates deterministic synthetic order-book scenarios and checks how a local analysis path handles gaps, duplicates, reordering, staleness, epoch resets and corrupt frames.

01 / Product

One local path from scenario to evidence.

Designed for data, infrastructure and quantitative QA engineers who need repeatable failure cases without connecting a live feed.

01

Generate

Repeatable synthetic scenarios with recorded seeds, configuration and explicit boundaries.

02

Observe

Feed-health observations and bounded planted market-structure events with traceable inputs.

03

Verify

Checksummed evidence that can be inspected and regenerated from its recorded local inputs.

02 / Scenarios

Make feed faults visible and reproducible.

The current synthetic family plants six operational fault types. Each observation is bounded to its declared fixture and evidence.

01

Gap

A missing frame becomes an explicit observation.

02

Duplicate

Repeated delivery is distinguished from new input.

03

Reordering

Out-of-order frames retain their delivery context.

04

Staleness

Market-frame silence is separated from keepalive traffic.

05

Epoch reset

Reconnect boundaries start a fresh numbered epoch.

06

Corrupt frame

Malformed input is refused instead of silently reused.

03 / Evidence

A small result that carries its own checks.

The installed CLI writes sealed synthetic event rows, result metadata and SHA-256 sidecars into a new local directory.

OWNER-SIDE CLEAN SIMULATION

40.462 seconds

The Windows offline kit completed its clean owner-side setup below the five-minute acceptance limit. Independent outsider testing remains open.

  • Hash-locked local wheels
  • No package-index fallback
  • Six checksummed synthetic observations

04 / Boundaries

Clear limits are part of the product.

NOXINDEX currently demonstrates a local synthetic engineering workflow. These limits stay visible wherever the product is shown.

  • Synthetic research events only.
  • No live market connection.
  • No orders or execution.
  • Not a trading signal. Not investment advice.
  • Synthetic results do not estimate real-market behaviour.
