I've run into a bit of a problem with the historical advance/decline data.

First of all, there is a difference in the number of data points between the advance series and the decline series, on a daily frequency. From the start for both, 13/5/2002, advance (II5A.Z) has 2609 points, while decline (II5D.Z) has 2607 points. On top of this, the advance series isn't complete either because there were actually 2617 trading days in the period.

What gives?

Hello impairsonator,

I will look into this and get an answer.
I show that we are missing a daily value for II5D.Z on 3-13-2003 and 3-25-2004.

Hello -

We were able to find and add missing daily values for both symbols on 11-24-06, 3-21-07, 7-3-07, and 3-11-08.
Also, the two missing values on 3-13-03 and 3-25-04 were due to both days having a value of 0 - that is a bug on our side that we need to address. Thanks.
