“…The use of simple machine learning approaches is one of the strengths of this research, which despite the simplicity of the models, has reached acceptable results, but the selection of features manually is one of the weaknesses of this research. Research (39) has been a little more detailed in classification and has used three strategies (1) (sell), 0 (hold), and -1 (buy) for classification. This study considered the use of deep learning models to extract features automatically.…”
