There is something wrong with the volume line. Since October 2009, every month is a perfect match in terms of volume. That seems statistically impossible that for 2 years running, there would be exactly the same number of condos sold yoy. Can you update with actual volume?
You may be confusing the two lines. The lighter blue is the index and the darker blue is the volume.
The index line at the bottom looks flat, but that's because the vertical scale is so small, the peaks and valleys are flattened out.

Not at all. Look the volume number for 2011, and the corresponding month for 2010. They're the same, month after month. It shows on the volume graph, like twin mountains.
Duh, now I see it. My lousy pattern-recognition....
2009-11 through 2010-10 is exactly the same as
2010-11 through 2011-10.
Looks as if somebody mis-pasted a year's worth of cells.
we have sales vol charts, but we set it to a 90 day lag to adapt to the lag between city filings and actual sale date. Ultimately for the sales volume charts, we count the sale date not the filing date, so we naturally need to wait for sales to come in before publishing data - otherwise it will be incomplete and need to be revised later on once more sales file in.
Our last sales vol chart ends at Sept 14th, or 3 months ago, when we saw 58 closings a day. That still reflects the strong action from Q3. We dont yet show the slowdown in sales volume due to the 90-day lag setting, but pending sales trends over the last 2-3 months suggests sluggish sales volume for Q4.
We all know how Data from RE brokers is BS

I doubt Streeteasy's magic unicorns deliberately c&p 12 months of volume numbers. NAR has orcs, totally different animals.
Hiya Streeteasy fairies (elves?), bumping this up for an answer.
I am a licensed RE Broker living and working in Park Slope, Brooklyn. I am looking for condos in the 350K range. If you have listings that fit those perameters please contact me asap at ajg0103@yahoo.com as I have to very motivated buyers, both of whom have been pre-qualified.
Thank you, Alan Gordon
Thanks. Looking into it now...
NWT got it right, a "mis-paste" on our side.
The data has been corrected. We apologize for our mistake.
Who knew street easy is owned by Lawrence Yun?
Thank you but! the initial 12-month series went like this:
467 621 463 458 518 541 532 711 576 539 456 420
The new November 2009 to October 2010:
1150 591 928 458 660 508 542 575 697 584 475 440
Now, if the numbers were a bit higher, I would think "well, going back, more closings were reported, so the numbers are now more complete and accurate." However, some numbers are now way higher, some are way smaller. That's curious. In addition, the initial 12-month series cannot be found anywhere. If it was copied from somewhere else, where from? So this is not some random c&p error, there is some data integrity issue to address.
The underlying data did not change... a separate table is used to generate the graphics and excel export, and we made a mistake when updating that table. That particular step is made by hand, but we're looking into automating it to avoid any future errors.
Also, as you mentioned, the numbers for each month tend to change slightly when more closings are reported. But that's not what happened here.
In that case, you should look at the entire series going back to 1995, because the initial numbers had been there for over a year. The only reason the error was caught is because of the second error of c&p 12 months into the next.
