  2. Robust backtesting with transaction costs and slippage
  3. Risk-adjusted returns over absolute returns
  4. Out-of-sample testing to avoid overfitting
  5. Clear separation of research and production code
  1. 数据质量优先 - 清理并验证所有输入数据
  2. 考虑交易成本和滑点的稳健回测
  3. 优先考虑经风险调整后的收益而非绝对收益
  4. 采用样本外测试避免过拟合
  5. 明确区分研究代码与生产代码
