Trading Infrastructure

SYSTEM 01

Event-driven infrastructure for execution, reconciliation, monitoring, and operator visibility under live trading pressure.

What this proves

I can separate desired state from provider-confirmed truth, expose drift, and leave an operator with a reviewable recovery path.

Record Status: proof artifact v1
Type: Execution and observability infrastructure
Domains: trading infra / execution / risk / observability

[01]

Problem

Trading systems fail less from lack of signals and more from state drift, unclear ownership, and invisible execution failure.

[02]

Context

Built around environments where order intent, external provider state, risk limits, and operator attention all move at different speeds. The important work is making state legible before pressure turns it into guesswork.

[03]

Architecture

Market data -> signal -> portfolio -> risk gate -> execution -> service-provider gateway -> reconciliation -> monitoring.

[04]

Decision Boundaries

B01 Portfolio owns desired state.
B02 Risk owns what must not happen.
B03 Execution owns how action enters the market.
B04 External provider records and reconciliation provide ground truth.

[05]

Trade-offs

Prioritizes deterministic state, auditability, and recovery over speculative optimization or visual flourish.

[06]

Artifacts

Systematic trading infrastructure demo: replay, portfolio netting, simulated execution, reconciliation, and performance output.
Eigenstate-native trading state replay: static trace UI for intent, risk, provider-confirmed state, reconciliation, and operator visibility.
Boundary mapping: local event stream to message layer, simulated provider boundary to service-provider adapter, local dashboard to operator console.
Focused scenarios for risk rejection, provider rejection, partial fills, reconciliation mismatch, and trace replay.

Proof Object

Trading State Replay

A static, anonymized Eigenstate proof artifact for trading system design. It demonstrates replayable inputs, stable intent boundaries, provider-confirmed state, reconciliation, and operator visibility without exposing live execution details.

S01 execution intent
S02 desired position
S03 risk gate
S04 order command
S05 service-provider event
S06 reconciliation
S07 operator view

Sanitized event shape

One public-safe contract slice from the replay path. Values are fixture identifiers, not live symbols, venues, or account data.

intent_id: fixture-intent-017
desired_position: +2 target quantity
risk_decision: accepted before provider routing
provider_callback: partial_fill / filled +1
confirmed_position: +1 provider-confirmed
reconciliation_diff: +1 residual against target
operator_flag: drift visible for review

Intent, risk, provider callback, and reconciliation remain separate records; provider-confirmed state is the recovery source when internal target and external state diverge.

Failure Mode

Internal desired position and service-provider-reported position diverge.

Recovery Rule

External provider truth wins; reconciliation updates portfolio state and marks drift in the operator view.

[08]

Connection to Current Focus

Trading infrastructure trains the same discipline needed for relationship-memory systems: provider-confirmed truth, state drift, reconciliation, auditability, and operator visibility.

[09]

Next Structural Improvement

Make failure states and recovery playbooks visible as first-class system artifacts.

What it demonstrates

High-context infrastructure, state recovery, risk boundaries, and auditability.
