Hello Adam,
When you generate the EAs you can set up the range for the SL and the TP. r you can choose exact values to use.
Look at the first picture from Petko, you can see min and max in pips. The EA Studio does not give you 80/120 alone, you have set it this way in the first place(maybe you did a huge range and it found the best parameters). For me, these are not bad levels by the way. You make conclusions too quick just from a couple of weeks.
Once again, if you want to use precise levels in SL and TP, you can set it there, and all generated EAs will use those levels.
