This screen offers no additional choices, as there are no settings for cash series. Be sure to select your detrend preferences, date range, post processing and export options (for portfolio) before clicking OK to complete the selection.

Some cash series are available as reported, and others are available on the day after reported. Please check the factsheets, including footnotes, for details on availability and timeliness.
