Technical background for stock robotics?

Question

Programming

I had a "childish" naive dream - to write a robot for stock trading, which will earn money for me in real time. Yes, playing on the stock exchange is by and large a casino and you can easily earn yourself a deep minus. But I want to try something, and I can control my greed)
What can be improved on the technical side? As I understand it, here the main emphasis will be on algorithms and the assessment of the news background, and this is, respectively, parsing, text data analysis and machine learning.
