NRSS

The short non-response schedule is produced every 30 minutes at about three minutes past the half hour. It covers eight trading periods, beginning with the trading period indicated by the date and time in the name of the CSV file, and extends seven more trading periods into the future.

For a variety of reasons, there will be occasions when there are fewer than 48 NRSS CSV files per daily zip file. We will make no effort to track down any missing files or explain why they are missing.
