This paper introduces a sophisticated deep learning model designed to predict high-risk behaviors in financial traders by analyzing vast amounts of transaction data. The model begins with an unsupervised pre-training phase, learning distributed representations that capture complex data relationships autonomously. It then utilizes a deep neural network, enhanced through supervised learning, to classify and predict traders' risk levels effectively. We specifically focus on financial spread trading related to Contracts For Difference (CFD), identifying potential misuse of insider information and assessing the risks it poses to market makers. By distinguishing between high-risk (A-book) and lower-risk (B-book) clients, the model supports strategic hedging decisions, crucial for market stability. Our extensive evaluations confirm the model's robustness and accuracy, highlighting its significant potential for practical implementation in dynamic and speculative financial markets where past trading performance may not predict future outcomes. This advancement not only refines risk management strategies but also contributes broadly to the domain of financial technology.
