This article aims to analyze the existing methods and algorithms that are used to develop these trading platforms in order to improve their efficiency in predicting securities prices for portfolio investment. The authors of the article considered the following methods: genetic algorithms, Markov random decision making, GDQN and GDPG machine learning methods, naive Bayesian algorithm combined with Adaboost algorithm, semantic analysis of financial news, Decision Stump, simple linear regression, support vector machine using radial basis kernel functions.
