Risk-Gated Market Analysis Engine

A TypeScript research system that evaluates market signals through data-quality, liquidity, context and risk gates before paper-trade consideration.

Generalised from private project evidence. This is a research and paper-trading system, not a claim of live or profitable automated trading.

Engineering scope

Responsibility across
system boundaries.

The public scope is intentionally limited to the represented engineering work. It does not imply sole authorship where the work was collaborative.

Role & contribution

  • Backend architecture
  • State and evaluation workflows
  • Research tooling
  • Next.js dashboard integration

From constraint to system

Decisions that make
complex work calmer.

Challenges, implementation choices and resulting capabilities—without converting private work into unsupported performance claims.

01

The constraints

  • Rejecting stale or incomplete market data before it reaches decision logic
  • Keeping evaluation results reproducible across live-like and replay contexts
  • Making a complex decision path understandable without implying certainty
02

The approach

  • Introduced explicit data-freshness, market-context, liquidity and risk gates
  • Used replay-compatible snapshots, audit commands and explanation-oriented result objects
  • Connected evaluation state to a cockpit interface and paper-trade reconciliation workflows
03

What it established

  • Created a fail-closed path for evaluating candidate signals
  • Made research runs and decision reasons easier to inspect and reproduce
  • Kept live execution outside the represented product boundary

Public case-study boundary

Generalised from private project evidence. This is a research and paper-trading system, not a claim of live or profitable automated trading.

Client identifiers, confidential assets, private repositories, commercial data and unverified performance figures are not part of this case study.
