Yeah, how does it work? Usually when we are talking about machine learning we usually talk about computers learning a system so I presume you are at least talking about technical analysis or at least supply and demand topics. Another thing I like to point out is how reliable are these predictions at, since we are already talking about machine learning I know that these kinds of systems would at least take a while before they get more and more accurate with what they are doing. Putting in the system reliability for you prediction, some sort of a percentage out of 100 would at least give a disclaimer for your viewers that the predictions being given by your system isn't a 100% guaranteed price movement.
