Scheme? I guess trading bots don't scheme on my side.

They are just a tool to be used in trading and they won't be worked if you don't know how to set up a bot. In short, the trading bot will work just because of you, and it will execute on behalf of you when you are away from your computer or even while you are sleep.

If you will have a plan to use a trading bot, make sure you aren't a newbie in trading. Because this automated tool will not work on its own without your command. Still, you will be used your strategy and skills.
