Artificial Intelligence (AI) is sometimes used in Forex robots. One of the first popular robots to use it was IvyBot. It has employed AI to adapt to market conditions, which is a huge obstacle for expert advisors. If it worked, should have been obvious after a few months of activity.
Unfortunately, IvyBot didn’t do anything significantly better than other robots, perhaps because the AI was too primitive or perhaps this technology still has a long road to go to be of better use. The bottom line is that currently there’s no big advantage of having a Forex robot with AI or not.
