Conditional Generators for Limit Order Book Environments: Explainability, Challenges, and Robustness.
In: ICAIF '23: 4th ACM International Conference on AI in Finance.
Abstract
Limit order books are a fundamental and widespread market mechanism. This paper investigates the use of conditional generative models for order book simulation. For developing a trading agent, this approach has drawn recent attention as an alternative to traditional backtesting, due to its ability to react to the presence of the trading agent. We explore the dependence of a state-of-the-art conditional generative adversarial network (CGAN) upon its input features, highlighting both strengths and weaknesses. To do this, we use "adversarial attacks"on the model's features and its mechanism. We then show how these insights can be used to improve the CGAN, both in terms of its realism and robustness. We finish by laying out a roadmap for future work.
