For many ones, trading is depending on robots and working with programs. I have never used robots but never heard good things about robots.
Best working robot is the one that you created using your own ideas, technical, market, programming and bulk of other knowledges. And after you create it you understand how dumb is the question you ask us.
I can not imagine that there are people who are believing robot and saying 100% profit for last 3 month. Is it really working?
