How to make money from EAs (trading robots)

Has anyone here adapted their strategy to an EA ?
If so wax it successfully done and what were the pros and cons
The very first thing and actually the fundamental one is to find a proper expert advisor, it might be either paid or free, either require access to the internet or not, either it's fully automated or not.
There are dozens of peculiarities in trading with EAs, but the fundamental thing is the difficult one. It's tough to find a good expert advisor, because there are either bunch of scams in the world of EA, or they don't work properly. However, I know and actually I used the EA which was awesome, but I understood that there is nothing better than trading on your own and rejected the idea of using EA.
