I've added two new features today. The first is that you can now see the block in which an account was registered in addition to the date, it's a small change but handy imo.
The second is a bigger feature: I'm now tracking feed prices over time as well as the 24 hour volume weighted average for all market assets. I'm also tracking the current price via the last completed trade, and I'm using all this to plot the deviation from the feed value of the actual trades within the system. You can check it out here:
http://bitsharesblocks.com/charts/feeds?asset=USDA couple things to note: if there hasn't been any trades within the last hour, I'm setting the "Latest price" equal to the feed price. This is to mitigate the effect the feed moving without any trades happening would have on the deviation statistics. Secondly, if there's no volume in the last 24 hours, I do the same for the volume weighted average. Thirdly, the deviation is calculated with respect to the "Latest price", not the volume weighted average. As this is a single trade it might be further off from the feed price than the average price, please don't use that as an argument that the peg is failing, it isn't..
Fourth: there's only a couple hours of data so far so it's not that interesting yet, but it will hopefully grow in usefulness.
Enjoy
