I can't see any data the last hours from bitsharesblocks

Yea I just got a message about this, looks like the backend is down but for the first time in a long time I'm away for the day with no access to my computer. I'll see if I can get to it from my phone, but you can also switch the api server using the button in the footer.

yup same for me!

I've just pushed a pretty huge update to Bitsharesblocks, especially on the backend. I've rewritten large parts of the backend to be more reactive and be able to handle tracking order books for all assets. Simply put it now only updates those assets which have seen action since the last time it updated, while before it was simply on a fixed interval. The order_history command is too heavy for a fixed update frequency but this way it works.

You'll see the following new on the assets pages:

• Orderbook in asset page, last 10 orders
• Last price, daily range and daily volume on top of the orderbook graph
• Better sorting of market assets: secondary sorting by number of valid feeds then by name
• Better sorting of user assets: secondary sorting by status (initialized), then by name
• Market cap for user assets based on last price: I know this can be very misleading at current volumes but even so I prefer it this way

Great work!!! I'm just getting into the community and your webpage helped me a lot!! thanks! 

about SEO, there are some free tools that help to give a quick bullet list of things to improve: https://www.lipperhey.com/en/analysis/quick/ most of them take 2 minutes to fix.

I've made some modifications to the asset pages, it is now split into two tabs: Orderbook and Asset Info. This means old links like assets/asset?id=USD no longer work, the new syntax is:

http://bitsharesblocks.com/asset/orderbook?asset=USD

http://bitsharesblocks.com/asset/info?asset=GOLD

I've also made lots of small fixes, notably I've corrected the sorting for shorts, they're now sorted by price limit first and interest second.

That makes sense!

market volume in Silver are not correct. I traded the last 24 Silver and the volume is 0.

I'm having to rely on price history data to calculate the volume so there's a certain delay before it shows up. I think you can consider the 24 volume to be delayed by up to an hour in the worst case. I'll improve this eventually but I'm limited by the performance of the client atm.

i am not sure if this is the case. the traded silver never shown as volumen.

You appear to be right, I've made a Github issue for this: https://github.com/BitShares/bitshares/issues/1300

The discrepancy appears to be huge, I was using about 500 BTS of volume but the actual volume is >200k BTS

Hello svk.
Can you fix this small display bug?...

Yes I can! Try it now

Hello svk.
Can you fix this small display bug?

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=USD

A 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
