Financial markets are one of the main components of the economy, and their growth and
development is a crucial and significant factor in the world. Meanwhile, artificial intelligence is an
exponentially developing field. The use of artificial intelligence in financial markets is a new and intensely
developing phenomenon, requiring extensive research. The aim of this paper is to present a methodology
of machine learning-based method effective application in financial instrument price forecasting in
comparison with the traditional method, namely ARIMA. Consequently, the scientific literature on
financial markets, traditional and machine learning-based methods were analyzed. Finally, a theoretical
model for stock prices forecasting is presented. The main results of the analysis show the most extensively
techniques applied in the stock markets and cash markets are methods of time series analysis, econometrics
and machine learning. After analysis of methods of machine learning, it can be found most popular
supervised learning algorithms are linear regression, decision trees/regression tree, random forest
classification/ regression, and support vector machines. As a result of the research, a theoretical model for
financial instrument price forecasting is presented and discussed. Based on the theoretical approach
proposed several experiments will be performed using ARIMA and Support Vector Regression (SVR)
methods
