Abstract: The stock market is a significant part of the financial system in China,and its stability of is crucial for overall financial stability.Stock price mani-pulation has long been a topic of widespread concern within it.Existing researches on stock price manipulation detection models are often based on either daily or intraday trading data.However,stock manipulation could have both short-term and long-term impacts,and a singular temporal focus may not comprehensively capture the pattern characteristics of stock manipulation.This paper proposes an ensemble learning model for stock manipulation detection with multi-scale data.The model ensembles sub-models utilizing minute-level and day-level trading data,enhancing the capability to identify trade-based stock manipulation behavior.Comparative experiments show that the model type proposed in this paper,which uses multi-scale data,has a large improvement in various metrics such as AUC,accuracy,recall,and precision.

Key words: Stock manipulation detection, Ensemble learning, Deep learning, Recurrent neural network, Multi-time scale
