🎯 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
