Introduction to Nexus II
Nexus II is a deterministic, contract-driven trading system augmented by a self-learning AI advisory layer, built for operators who demand clarity, control, and auditability in live market environments.
It is not a signal toy, a black-box AI, or a one-click trading bot.
Nexus II is a decision engine—one that combines disciplined rule-based execution with adaptive intelligence, while preserving explicit state, strict risk control, and full traceability.
Why Nexus II Exists
Most trading systems fail for predictable reasons:
The Role of the Self-Learning AI
AI as an Advisor, Not an Executor The self-learning AI in Nexus II does not place trades and does not mutate the ledger. Instead, it operates in an advisory capacity, providing:
Learning From Reality, Not Backtests
The AI learns from:
Hard Separation: Learning vs Acting
Nexus II enforces a strict firewall:
Online Learning With Guardrails
The AI learns continuously in shadow mode:
What Nexus II Is (and Is Not)
Nexus II Is
Core Operating Philosophy
1. The Ledger Is Truth All positions, P/L, and capital usage originate from a single authoritative ledger. The AI observes the ledger—it does not alter it.
2. YAML Is the Single Source of Truth All system behavior—risk, sizing, feature flags, and AI enablement—is controlled via configuration, not code.
3. Static vs Dynamic Data Is Sacred The AI may analyze static trade parameters and dynamic market data, but it may never rewrite history.
4. Determinism Before Intelligence Learning enhances the system only where determinism is already correct. If the system cannot safely explain or gate an AI recommendation, it is ignored.
5. Explicit Trade Lifecycle
Preview → Armed → Open → Closed The AI may advise at any stage—but it never skips one.
Who Nexus II Is For
Nexus II is designed for:
A Final Note on Learning
Nexus II does not chase intelligence for its own sake. The self-learning AI exists to:
In uncertain markets, Nexus II ensures the system learns—without forgetting discipline.
You are required to have Schwab API access to run the system. Without access, the system is useless.
This is a beta version of the code and currently only trades paper. It will NOT take real trades (yet)

Why Nexus II Exists
Most trading systems fail for predictable reasons:
- []State is implicit instead of explicit []Restarts create duplicates []Risk rules are scattered or bypassed []Static trade parameters mutate over time []Machine-learning models leak future information []“AI decisions” cannot be explained after the fact
The Role of the Self-Learning AI
AI as an Advisor, Not an Executor The self-learning AI in Nexus II does not place trades and does not mutate the ledger. Instead, it operates in an advisory capacity, providing:
- []Signal confidence scoring []Regime classification (trend vs chop, volatility state, liquidity state) []Override recommendations (strengthen, weaken, or abstain) []Post-trade outcome analysis
Learning From Reality, Not Backtests
The AI learns from:
- []Actual executed trades []Actual fills and slippage []Actual exits and outcomes []Actual regime conditions
Hard Separation: Learning vs Acting
Nexus II enforces a strict firewall:
- []Static trade data is immutable []Ledger records are append-only []AI outputs are recommendations only []Execution logic remains deterministic
- []“Do nothing” []“Reduce size” []“Require higher confirmation” []“Skip in this regime”
- []Risk rails []Capital constraints []Deduplication rules []Trade lifecycle state
Online Learning With Guardrails
The AI learns continuously in shadow mode:
- []Evaluating what would have happened []Comparing outcomes against baseline logic []Tracking confidence calibration []Measuring stability over time
- []Changes are reversible []Rollback triggers are enforced
- All AI-influenced decisions are logged
What Nexus II Is (and Is Not)
Nexus II Is
- []A ledger-first trading system []A state-aware execution engine []A learning-augmented decision framework []A platform where AI improves judgment, not authority
- []An autonomous AI trader []A self-modifying codebase []A system that “learns live” without safeguards []A model that cannot explain itself

Who Nexus II Is For
Nexus II is designed for:
- []Traders who want adaptive intelligence without surrendering control []Quants who demand clean learning boundaries []Developers building long-lived automated systems []Operators who need to explain why a trade happened weeks later
A Final Note on Learning
Nexus II does not chase intelligence for its own sake. The self-learning AI exists to:
- []Reduce overtrading []Avoid bad regimes []Improve consistency []Enforce humility when confidence is low
In uncertain markets, Nexus II ensures the system learns—without forgetting discipline.
