StockFormer Data File Explanation and Execution Method

Overview of "StockFormer" Code

This is the code accompanying the paper titled "StockFormer: A Swing Trading Strategy Based on STL Decomposition and Self-Attention Networks," which is currently under consideration for publication in the International Journal of Forecasting. The preprint of this paper is available on SSRN. The code provides a comprehensive framework for implementing the StockFormer model, including data preparation, model training, and backtesting. You can access the preprint at: SSRN Preprint.
