Hi Puppy
Slovenia (CET) is 1 hour ahead of GMT so CET = GMT +1 hour.
When I am eating my porridge tomorrow morning, Monday at 09.00 hours GMT (and checking how my Bots are performing) it will be 10:00 CET in Slovenia and so I hope your PRT Platform will have been showing realtime prices since at least 08:00 CET Slovenia time tomorrow, Monday 28 Nov 16.
Let us know how you get on
Sleep Well
