## Archon Integration
|
||||
|
||||
Although Archon is not currently available, we've prepared for integration:
|
||||
- **archon_update_plan.md** - Detailed plan for updating Archon
|
||||
- **Archon tasks** - Defined tasks that would be created in Archon
|
||||
- **Workflow documentation** - Following Archon workflow principles
|
||||
|
||||
## Key Design Principles
|
||||
|
||||
### 1. Risk First
|
||||
All trades pass through risk management before execution, ensuring no trade can bypass risk controls.
|
||||
|
||||
### 2. Deterministic
|
||||
Identical inputs produce identical outputs for reliable testing and validation.
|
||||
|
||||
### 3. Modular
|
||||
Strategies are thin plugins, with the SDK handling all infrastructure concerns.
|
||||
|
||||
### 4. Observable
|
||||
Structured logging with correlation IDs throughout for comprehensive monitoring.
|
||||
|
||||
### 5. Test-Driven
|
||||
Comprehensive unit test suite with >90% coverage ensures reliability.
|
||||
|
||||
