Let me explain a little about expert advisors:
EAS is just an automatic form of manual trading method. If you have a trading plan or method that works for you, there are good programmers who can convert this into automatic trading for you and it will trade exactly as if you were the only trade. But when many traders hear robots or EAs, they quickly assume it's crazy crazy but this isn't true.
No matter how complicated your trading method is, you can turn it into a robot or EA and it will trade exactly as if you are one and better yet, no fear or greed but will trade with the right arrangements.
You might not believe this, but 95% of traders fail not because they can't trade but because they can't control their emotions and this is the place where Eas or robots enter.
I still made some manual modifications but EA started trading even when I wasn't online because I used a service called the VPS service where there were no internet problems, no power failure but the trade was running 24/7. So understand that Robot is just a trading method from one trader out there, so develop your own trading method and if you like, make it a robot and trade easily.
don't listen to pessimists and those who are full of themselves
