You can update all studies in the account by clicking on the ‘Portfolios’ bar on the ‘My Studies’ screen then looking for the ‘All Studies’ row and clicking on the Refresh (circular) icon to refresh/update the data in all studies.
You also have the ability to update all studies in a single user-defined portfolio in a similar manner.
