## 🎯 Project Vision & Purpose

### Core Mission
Build an institutional-grade trading SDK that:
- **Protects Capital First** - Multi-tier risk management before profit
- **Makes Intelligent Decisions** - Grade trades based on multiple factors
- **Executes Professionally** - Sub-200ms latency, thread-safe operations
- **Measures Everything** - Comprehensive analytics and attribution

### Why This Matters
- This is **production trading software** where bugs = real financial losses
- System runs **24/5** during market hours
- **Institutional-grade quality** required (not hobbyist code)
- Must be **deterministic** for backtesting and auditing
