Hello,
it is possible. You can mark your portfolio Trading Status as "Fully inactive" in Portfolio Manager, then PTL Trader won't enter or exit any positions automatically. In PTL Trader there are buttons "Open long", "Open short" and "Close position" for each pair of your portfolio. You can test this before you subscribe to premium, so no need to pay in order to test if this approach suits your needs. Test on paper account first.
Kind regards,
Karel
