Oh there are so many reasons. Our stats will more-or-less reflect each other but can get out of sync for a number of reasons e.g.
When you copy me initially you pay the spread then so you immediately take a small loss versus my portfolio.
If I add more funds, you will need to add the corresponding percentage of funds to pick up future trades in the same proportion as I do.
If you copy me with a very small amount (less than a few hundred dollars) you may not pick up my smaller trades i.e. if the trade would be less than $1 for you then eToro doesn’t open a position.
You manually close trades or your SL is hit.
