To copy a trader on eToro, you need to have an account (click here if you don't have one yet) and it has to have enough funds (the minimum is $200 to copy a trader). Once you have a funded account, follow the steps below:
Open the eToro platform or app and click on "Discover". Then look for the "CopyTrader" section and click "View all". This will take you to the copy trading page.
Take a look at the profiles of the traders. Try to explore their stats, the markets they are investing on, their success rates, etc. After that, decide on who to copy.
Once you've chosen a trader, go to their profile and click on the "Copy" button. This will open a pop-up window.
Set the amount you wish to invest for copying this particular trader. Keep in mind that the minimum investment amount is $200 but for more experienced traders, it could be higher. You'll get a notice there anyway on what's the minimum amount you can invest.
Finally, execute the trade by clicking on the "Copy" button. That's it, you've copied a trader on eToro. 🙂
