Algorithmic trading is the use of automated computer programs to execute trades based on pre-defined rules and strategies. Machine learning (ML) and deep learning (DL) have revolutionized the field of algorithmic trading by providing powerful tools to analyses complex data and identify patterns that can be exploited for profitable trades. In this paper, we explore the question of which is better suited for algorithmic trading: machine learning or deep learning? We begin by defining machine learning and deep learning, outlining their strengths and weaknesses, and discussing their applications in algorithmic trading. We then compare the performance of various ML and DL algorithms on a range of trading datasets, including stock prices, foreign exchange rates, and commodity futures. Our analysis shows that both machine learning and deep learning have their own advantages and disadvantages, and the choice of which approach to use depends on the specific trading problem and available data. While machine learning algorithms are generally simpler and faster to train, deep learning algorithms can learn more complex patterns and may outperform machine learning on large and diverse datasets. IN conclusion, there is no clear winner between machine learning and deep learning in algorithmic trading. Rather, traders should carefully consider the characteristics of their data and the requirements of their trading strategy when deciding which approach to use.
