actualisation web data

Hi

I have a data from web on my dashboard. The others datas come from excel through power desktop with a manual actualisation (excel to power desktop, and power desktop to power service).

I would appreciate if just the only data from web of my dashborad (share quote from bloomberg website) will automaticaly actualise every day, without any intervention from me and with no actualisation from my excel spreadsheet.  

Thank you in advance for your precious advice.
