Quant & ML Trading — Complete Toolkit
Overview
Five powerful tools for quantitative strategy work:
- Strategy Validation — backtest tearsheets, walk-forward OOS, Monte Carlo, sensitivity, A/B testing
- Genetic Optimizer — evolve strategy parameters using evolutionary algorithms
- Decay Monitor — detect when a live strategy is losing its edge
- RL Trade Agent — reinforcement learning agent (DQN) that learns to trade from market replay
- AI Signal Aggregator — combine signals from all strategies using weighted voting + ML meta-model

Anti-Overfitting Rules (ALL skills)
- Always use walk-forward OOS — never optimize on all available data
- Monte Carlo bootstrap required before any live deployment
- GA/RL results MUST be validated on unseen temporal data
- Meta-model must be re-trained monthly with rolling walk-forward
- Live vs backtest Sharpe gap > 0.5 = pause the strategy immediately
