A trading bot was designed by its own program to work on behalf of you so it means the trading bot will not work without your knowledge.  It will not work on its own, you need to command the bot and set your trading pick which executes the buy and sell at the time you have set.  Maybe you're thinking that trading bot is a money maker machine, doesn't how it will work.

There's a lot of explanation on Youtube video and you can google search how automated trading bot will work, you just need a bit researchful.

However, I suggest to not rely on the bot, much better if you will execute trading by your own.
