Hey Eddie,
Yes, it can. When you place the Portfolio EA onto your chart, select the input tab, double-click on the base number in the list and change it to any number you’d like, and hit the Save button. You can also do it when the Portfolio EA is already on the chart, by clicking on the smiley face in the top right hand corner, which will bring up the same EA Properties window. Just keep in mind that if you do the latter, and the EAs have already opened and closed trades, when you analyse their performance in something like FXBlue, you’ll have the old numbers as well as the new.
Cheers,
Ilan
