Hi Xavier, yes it sound like you have a lot of questions and a coaching session would be useful. Please email [email protected] to ask how to set that up. These EAs can be used in many different way to trade really, but the way the app is designed the most common way is to trade them for a short time and select new ones to replace the old ones regularly. Also they don’t communicate with each other, so when compiling a portfolio a simple way is to sum the drawdowns of each and make sure that this isnt greater than the available drawdown on your account (wiht a bit of a buffer of course)
