Hello Oliver,
So, from what I can understand, the take profit was placed below the opening price of the position.
There is a reason for that and probably it’s because the trend changed the robot just placed the take profit a little below the opening price.
Another reason could be the spreads, you need to check what are the spreads of the account and what does the broker offers in spreads.
Hope that helps!
If you have any more questions, let me know!
Kind Regards,
Nikos
