英文摘要：
Calibrating a trading rule using a historical simulation (also called backtest) contributes to backtest overfitting, which in turn leads to underperformance. In this paper we propose a procedure for determining the optimal trading rule (OTR) without running alternative model configurations through a backtest engine. We present empirical evidence of the existence of such optimal solutions for the case of prices following a discrete Ornstein-Uhlenbeck process, and show how they can be computed numerically. Although we do not derive a closed-form solution for the calculation of OTRs, we conjecture its existence on the basis of the empirical evidence presented.

中文摘要：
使用历史模拟（也称回测）校准交易规则会导致回测过度拟合，进而导致表现不佳。在本文中，我们提出了一个确定最优交易规则（OTR）的过程，无需通过回溯测试引擎运行替代模型配置。我们给出了离散Ornstein-Uhlenbeck过程后价格存在此类最优解的经验证据，并展示了如何用数值计算它们。虽然我们没有推导出计算OTR的封闭形式解，但我们根据提供的经验证据推测其存在。
