Summary

The document introduces a framework for judging whether an autonomous trading strategy is likely to remain reliable beyond a historical simulation. It focuses on common evaluation pitfalls that can make a strategy look successful in backtests but perform poorly in live markets or on data excluded from development.

The proposed approach sets minimum test durations and requirements, then applies them to several published strategies used across different assets. The reported findings are that many strategies fail to demonstrate dependable investment performance. The framework is intended to help compare candidates and set more realistic expectations. The excerpt does not describe the specific tests, thresholds, strategy examples, or detailed results, so it supports the general evaluation principle more than a reproducible procedure. Its title emphasizes FX, but the text says the evaluated strategies manage a diverse selection of financial assets.

Key ideas

  • Historical backtest performance may not predict results in live markets or on unseen data.
  • Strategy evaluation should set minimum test periods and execution requirements.
  • The framework is applied to published autonomous strategies across multiple assets.
  • The excerpt reports that many strategies do not show reliable long-term investment performance.
  • Specific thresholds and test procedures are not provided in the excerpt.

In this paper, we propose a method for evaluating autonomous trading strategies that provides realistic expectations, regarding the strategy's long-term performance. This method addresses This method addresses many pitfalls that currently fool even experienced software developers and researchers, not to mention the customers that purchase these products. We present the results of applying our method to several famous autonomous trading strategies, which are used to manage a diverse selection of financial assets. The results show that many of these published strategies are far from being reliable vehicles for financial investment. Our method exposes the difficulties involved in building a reliable, long-term strategy and provides a means to compare potential strategies and select the most promising one by establishing minimal periods and requirements for the test executions. There are many developers that create software to buy and sell financial assets autonomously and some of them present great performance when simulating with historical price series (commonly called backtests). Nevertheless, when these strategies are used in real markets (or data not used in their training or evaluation), quite often they perform very poorly. The proposed method can be used to evaluate potential strategies. In this way, the method helps to tell if you really have a great trading strategy or you are just fooling yourself.
