Ok, I finally got a good translation regarding what the Chaomi site is showing in the market trends section. It looks like there are two main sets of data on this page. One set shows previous buy it now / fixed price sales, and the other section shows previous auction sales. I’ve been doing this daily post of auction trends when the data I have actually been looking at is the fixed price sales data. I apologize for this error, and I’ll be coming up with a way to monitor the auction data specifically. Until then, I’ll continue to post the fixed price sales trends (averages and floor prices).
I had a discussion in the comments section a week or so ago with Michael regarding the BIN sales reports. Michael mentioned that Chaomi may be logging a sale when a name disappears from the BIN listings when in fact, there was no actual sale. This is possible. I do not know exactly how Chaomi gets their data. Tracking auction sales is certainly the better way to go, and I hope to have something better soon.
