I think big financial institutions or banks may have it but keep it like top-secrect.
I tested some trading robots, met some IT guys who create trading robots based on AI.
An AI trader is easy to create.
The issue is the dataset. Selecting the right variables and building the neural net. A regular user will not have access to millions/billions of previous trades to train the ML algorithm.
maybe, because if a certain company or bank is earning huge money from their ai trading robot, why would they share it to others? definitely, they will keep it to themselves as much as possible and gain from it.
vod is right. the more data points the software has, the better. and a regular user will not have those thousands of data points. usually top companies have access to such Big Data!
and this article is a proof that these financial institutions are really deploying their specific AI tools at their disposal
