AegisProject：多智能体协同的量化交易系统

AegisProject is a production-level AI-driven algorithmic trading system combining XGBoost and LSTM models with a multi-agent chain-of-thought reasoning layer. It uses three independent AI agents (technical, sentiment, volatility) for collaborative decision-making to generate explainable trading signals. Key features include transparent decision logic, integration of machine learning and symbolic reasoning, and risk management via the volatility agent's veto mechanism.

Traditional machine learning models (especially deep learning) in algorithmic trading are often 'black boxes'—they provide predictions but lack interpretability, which is critical in high-risk financial domains. Traders and risk managers need to understand decision logic to trust the system and intervene when necessary. AegisProject addresses this gap by combining ML with multi-agent chain-of-thought reasoning to deliver both signals and clear reasoning.

Machine Learning Layer

• XGBoost: Used for regression (predict next day's return) and classification (buy/sell direction) with features like RSI, MACD, moving averages, Bollinger Bands, volatility, momentum, volume signals, and log returns.
• LSTM: Handles time series prediction to capture long-term patterns and generate short-term price trajectories.

Multi-Agent Reasoning Layer

• Technical Analysis Agent: Analyzes tech indicators (RSI, MACD, EMA排列, Bollinger Bands) to generate directional signals with confidence scores.
• Market Sentiment Agent: Assesses volume patterns, price momentum, accumulation/distribution behaviors to predict price turning points.
• Volatility Agent: Classifies market volatility states (low/medium/high), detects extreme conditions, and supports risk management.

The aggregator integrates inputs from 5 sources: XGBoost (regression/classification), LSTM predictions, technical agent signals, sentiment agent analysis, and volatility agent state. It uses a weighted scoring system:

• 0.35 → BUY

• < -0.35 → SELL
• Between -0.35 and 0.35 → HOLD

Notably, the volatility agent has a veto: extreme volatility can override other signals to HOLD, protecting capital from unpredictable fluctuations.

Technical Indicators

All indicators are manually implemented using pandas/numpy (no third-party libraries) for full control, easy debugging, educational value, and performance optimization. Includes RSI, MACD, EMA/SMA, Bollinger Bands, ATR, volatility, momentum, volume indicators, and log returns.

Backtesting

Uses metrics like total/annual return, Alpha, Sharpe/Sortino/Calmar ratios, max drawdown, and win rate to evaluate strategy performance against benchmarks.

Tech Stack

• Backend: Python, FastAPI, XGBoost, scikit-learn, pandas/numpy, yfinance
• Frontend: Next.js, TypeScript, Tailwind CSS, Recharts
• Infrastructure: Docker, Docker Compose

API Endpoints

• /predict: Get ML model predictions
• /analyze: Get agent reasoning outputs
• /decision: Get aggregated final trading signal
• /backtest: Run historical backtest simulation
• /market-data/{ticker}: Get price and indicator data

• Educational Purpose: For learning/research only; not investment advice.
• Past Performance: Historical backtest results do not guarantee future returns as market conditions change.
• Model Risk: ML models may overfit historical data; multi-agent systems add complexity.
• Data Source: Uses Yahoo Finance (free and reliable but may have limitations in real-time, completeness, or accuracy for production use.

• Explainable AI: Multi-agent chain-of-thought provides transparent reasoning, building trust and aiding regulatory compliance.
• Multi-Dimensional Analysis: Three agents cover technical, sentiment, and volatility dimensions for a holistic market view.
• Integrated Risk Management: The volatility agent's veto mechanism embeds risk control into decision-making (not a post-hoc filter).

AegisProject combines ML pattern recognition with human-understandable reasoning, representing a promising direction for AI in quantitative trading. It serves as a valuable reference for developers learning to build full trading systems and a platform for researchers exploring explainable AI in finance. Future AI advancements may lead to more intelligent, transparent decision tools in financial markets.
