Manual trading is slow, exhausting, and subject to emotional bias. Retail investors struggle to actively manage diverse portfolios consisting of equities, options, and cryptocurrencies without twenty-four-seven supervision. Sigma IA democratizes institutional-grade trading by leveraging the power of NVIDIA’s advanced Large Language Models combined with the Model Context Protocol (MCP). It is a 100% autonomous artificial intelligence agent that operates directly on an Alpaca Markets brokerage account. Key Features: 1. True Diversification: The AI actively manages and rotates between high-growth stocks, value equities, ETFs, crypto assets, and options contracts. 2. Intelligent Position Sizing: Instead of blindly buying flat quantities, Sigma IA mathematically calculates precise share amounts to allocate exactly 5% of the portfolio's total equity to every trade, enforcing strict institutional risk management. 3. Market Sentiment & Risk Gates: The system halts high-risk trades (like volatile crypto) during turbulent market conditions, automatically switching to conservative ETFs based on real-time Fear & Greed Index data. 4. Real-time Dashboard: A modern React-based command center visually tracks the AI's 'reasoning', execution speed, and live PnL, providing total transparency. By combining Alpaca’s flawless API execution with NVIDIA's reasoning models, Sigma IA proves that complex, multi-asset hedge fund strategies are now accessible to the individual investor.
