Cortana
The engine that replaces the job. A multi-layer trading system I own, understand, and continuously improve. Short-term cash generation funds the operation. Swing compounds. Trend positions for macro cycles. All layers feed a unified signal hub that is the future commercial product.
State
- Owner: Cody Smith (solo operator)
- Architecture: Hub-and-spoke. See
concepts/hub-and-spoke-signal-engine.md. - Regulatory shape: Publisher, not advisor. Never FINRA/SEC registered.
See
concepts/publisher-not-advisor.md. - Validation mandate: Paper first, capital second. See
concepts/paper-first-capital-second.md. - Infrastructure: IBKR Pro + IB Gateway + Python + ib_async on Mac. Claude Code for implementation velocity.
- Primary repo:
~/conductor/workspaces/cortanaroi-mk2/(trading engine) - Brain repo:
~/brain/→cDSe2403/cortanaroi-brain
Layers
Layer 1 - 0DTE Cash Generation
- Purpose: Daily cash flow from 0DTE SPY signals
- Target: 10% wins, 80% win rate
- Status: Beta MK2 built. Paper trading. XGBoost signal layer with walk-forward + purged CV validation.
Layer 2 - Swing Trades
- Purpose: Compound capital on 2-5 day swing trajectories
- Status: John Neal building beta. I integrate beta → production into the Cortana hub, apply Layer 1 validation discipline, wire IBKR execution.
Layer 3 - Trend Trades
- Purpose: Longer holds on congressional disclosures, insider filings, macro regime signals. Munger 200-week MA framework + economic moat thinking.
- Status: Not built. Deliberate sequencing - Layer 1 must prove live first.
Key Metrics
- Win rate target: 80% (8/10 trades) - hard mandate
- Latency principle: “Early and right” beats “late and confirmed”
- Validation: Walk-forward + purged cross-validation per López de Prado
Open Threads
- Paper→live threshold: [No data yet] - specific validation metrics that graduate a layer from paper to small live sleeve
- Signal service API: [No data yet] - what fields subscribers consume, pricing tiers, go-to-market
- Securities attorney: [No data yet] - engagement status for publisher/ advisor line review before signal service launch
- Trader Tax Status: Filing with CPA. Section 475(f) election to evaluate.
