Being  someone from the IT field, I can say that with machine learning and Artificial Intelligence, we see a lot of robots created. The last one that I heard was AI VOLTEX, because I see their ads maybe once  a week on instagram.

That said, these robots by humans, and therefore, these humans have trained the robots to trade much like the creators trade. But then, there are some emotional and psychological triggers that these robots won't copy, that's why they are only robots.

I could also create a robot and train it to watch price action and the robot will understand and start executing the trades. But it won't have tha emotional or psychological effect on any trades. It's just sell or buy, based on the strategy it got trained.

Now, if you have a, let's say 80% win trading strategy for some forex pairs, or stocks, I believe you could build one and apply it to those pairs or stocks, and not to the overall markets. The Robots we see nowadays are like, use it for every trade on every pair or stock available. That for me, is a very wrong approach!
