System 02 / trading systems
Execution logic, translated into observable state.
We develop trading workflows that make signal timing, order intent, position state, risk controls, and failure behavior explicit—from platform addon to broker integration.
Illustrative lifecycle. Venue and connection behavior varies.

Capabilities / execution engineering
Build around state, not just signals.
An entry rule is a small part of a trading system. The surrounding software must handle platform events, broker responses, risk conditions, and differences between historical, simulated, and live operation.
- Platform engineering
- Indicators, strategies, addons, alerts, and interfaces for NinjaTrader 8 and TradingView, scoped to the actual platform event model.
- Broker and market connectivity
- API integrations that translate application intent into broker-specific order requests and preserve acknowledgement, fill, cancellation, and rejection state.
- Order and risk controls
- Pre-submission checks, position limits, session rules, duplicate-order protection, stale-state checks, and explicit stop or shutdown behavior.
- Operational telemetry
- Structured event logs, alerts, execution reconciliation, and monitoring surfaces that expose what the system believed and what the venue reported.
Execution control / 04 transitions
Design the failure path before the happy path.
Systems interacting with live markets need explicit behavior for stale data, rejected orders, partial fills, disconnections, restarts, and position mismatches.
Declare order intent
Define triggering state, timing, order type, quantity, destination, and expiration.
Apply risk gates
Check market state, position, limits, data freshness, and operational readiness.
Track venue truth
Separate requested, accepted, working, filled, canceled, and rejected states.
Expose the timeline
Record enough context to diagnose decisions and restore state after interruption.
Software can make controls explicit, but it cannot guarantee a fill, stop execution, uptime, profitability, or protection from market and technology risk.
Delivery sequence / controlled change
Move from definition to monitored operation.
The implementation path stays visible so platform assumptions and acceptance criteria are not discovered only after deployment.
- 01SpecificationPlatform, connection, instruments, timing, state model, and operating constraints.
- 02SimulationHistorical and controlled testing with declared fill, fee, and data assumptions.
- 03IntegrationConnection behavior, account state, order mapping, error handling, and permissions.
- 04ObservationLogs, alerts, reconciliation, deployment controls, and maintenance boundaries.
