daily_stock_analysisModel43/100 via “backtesting engine with 1-day validation and performance metrics”
LLM驱动的 A/H/美股智能分析器：多数据源行情 + 实时新闻 + LLM决策仪表盘 + 多渠道推送，零成本定时运行，纯白嫖. LLM-powered stock analysis system for A/H/US markets.
Unique: Implements continuous forward-testing (1-day validation) rather than historical backtesting, enabling real-time performance monitoring as new recommendations are generated. Aggregates performance metrics per strategy and per LLM provider, enabling A/B testing of different models and strategies. Builds a historical performance database that can be queried to identify which strategies/providers perform best in current market conditions.
vs others: More practical than historical backtesting because it validates recommendations against real market outcomes without look-ahead bias. More comprehensive than simple win-rate tracking because it calculates precision, recall, Sharpe ratio, and drawdown. Enables provider comparison (Gemini vs Claude) which most backtesting frameworks don't support.
