Architecture Governance

Runtime Flow (Authoritative)

SimpleORBNT8.cs
  -> NT8StrategyBase.cs
  -> SimpleORBStrategy.cs
  -> NT8OrderAdapter.cs
  -> PortfolioRiskManager.cs
  -> NinjaTrader 8

Responsibilities

• SimpleORBNT8.cs: NT8 entry point and platform lifecycle bridge.
• NT8StrategyBase.cs: orchestration, risk gate sequencing, execution handoff, platform callbacks.
• SimpleORBStrategy.cs: signal generation and confluence grading only.
• NT8OrderAdapter.cs: execution bridge to NT8 managed order APIs.
• PortfolioRiskManager.cs: cross-strategy risk controls and account-level enforcement.

Architectural Constraints

• Risk-first flow is mandatory; no strategy-level bypass of risk validation.
• Managed-order sequence remains required (SetStopLoss / SetProfitTarget before entry).
• C# 5.0 syntax only, .NET Framework 4.8 only.
• NT8 signatures must be verified against official NinjaTrader docs before API-touching edits.

Governance Notes

• Core Risk/Sizing/OMS/Intelligence/Analytics layers are treated as complete and stable unless explicitly re-opened by approved work.
• Hardening changes are concentrated in targeted adapter/utility components per active-work scope.
