Definitely auto trading can be done with United States account but the main requirement is you have to be very cautious while trading. Using market news blindly or just following the dealer can lead you to a dangerous situation. Always try to mold the information into your requirement and analyze yourself about the trades.
You know better about yourself. The risk tolerance factor, duration, investment amount is different for every user. And the tips provided by the broker is generalized therefore keep your requirements on top and then trade with news.
I am using Finexo since long and has never faced such problem. Though this is a smooth software which provides timely updates and trading tips yet i follow news only when i make them into my requirement and get it confirmed by their experts. That is the secret of my successful trading career.
Obviously all this one learns from his own experience after facing heavy downs.
