I tried to use predictions to guide my algorithmic trading strategies but did not have the success that I wanted. Instead for my stock trading i focused on an alternative approach based on portfolio optimization using the regret minimization framework. I wrote a Medium article: "Winning in Algorithmic Trading Without Predicting the Future: The Power of Regret Minimization," where I explore how regret minimization offers a practical, robust approach to stock trading. Link: I would like to know what you guys think about the article and get your feedback.
