I actually had a bumped on a trading bot called Bitcoin Revolution.
The bot is backed up by well known at very trusted people like Bill Gates.
Check that one out.

Most of the Trading bots will just cost you to lose your money.
But if you can find trading bots that are well built, and are programmed to analyze the market through different tools, that should be good.
The most rational bot should be your best choice.

Be careful.
