For some reason, majority believes that robots do trade on their own (doing all analysis, making decisions)...
First of all it is an automation tool! Saying that one trades better by hands is similar to saying that one can hammer a nail better with bare hands (like Chuck Norris in "Way of the Dragon" I assume).
Even if it's just a tool, you need to know how to use it, experienced trader should be experienced with bots too, not only with trading
