Lookinbg for round the clockhistorical DAX data

i

Im looking for historical dax data. But any data i see seems to end at 4.30 p.m. and begins at 8.00 a.m.

But on IG Index the DAX is trade able 24 hours a day. So obviously they are getting their data feed from someplace.

Does anyone know where I can get 24 hour DAX data?

I don't mind paying for it
