But @OP, you should not just rely on trading bots all the time, if you have time trying to spare it with and work it by hands. Working it personally will help to gain additional knowledge and experience so you can't be wonder why are losing or gaining.
It looks like the OP wants to join a trading competition. Lol, first rule here is that before you used bots you should at least learn the basics of trading. OP didn't mentioned that he has experienced but lets assumed that he doesn't. So having a trading bot is useless because you will be having a hard time setting up the parameters because you don't have a clue as to what those settings are in the first place.
We can recommend you the best bot, but if you don't know how to play with it, its going to be useless.
