I'm just curious about this things because I've heard and read some guys don't suffer loss using trading bots and creating one can bring you money. If they are openly discussed, I would like to know but if not please let me know. I've tried searching in the forum and all I see were posts from more than 5 years ago. Could any good person enlighten me about this concern? Thanks. 
If someone created a bot that's earning him money without risk, don't you think that everyone would be talking about it? Like someone told you, there is no bot that will automatically earn you money. Every trader that uses a bot spent some time fine tuning it because every bot trades according to an algorithm. Some traders use bot to do thing that a trader can't except if he looks at the charts all the time. For example, you can't set a buy order at some price and automatically set a sell order that will be placed if that buy order goes trough. People use bots for that.
