For me, that's the easy part. That's just neural nets, finite state machines and fuzzy logic ... I understand that part.
But what about the actual trades themselves? These systems seem to be charging subscription fees of up to $200 (or more) per month ...
* Do they actually authorize trades?
* Are they broker specific, or are they just emailing advice?
* If I buy Forex Robot XYZ for $X per month does that mean I have to ALSO have a specific brokerage account?
