Ah ok, sorry, there was a misunderstanding on my side. I was under the impression that the “align_periods” flag was used to perform “completion”, but obviously this is not the case. From your reply, then, I gather that the “align_periods” switch has no effect when you download just one series. Am I right?
Also: I understand that inserting NAs in “gappy” series is the responsibility of the original provider and if the original series needs completion, then DB.NOMICS will provide it as is and it’s up to the end user to fill the gaps as appropriate. This was not the original policy, though, right?
