HZcharts - Asset Explorer for Horizon [HZ]

HZcharts - Asset Explorer for Horizon [HZ]

I'd like to announce HZcharts: http://hzcharts.coin.emergate.net (or HZcharts.coin on Emercoin decentralized DNS)

HZchats is simple website for viewing information about assets and accounts on Horizon's Asset Exchange. It also provides a public api for retrieving live asset price and volume feeds, that can be used to list assets on sites like coinmarketcap.com. HZcharts is heavily inspired by http://nxtreporting.com/ as I use that a bunch and couldn't find anything equivalent for the HZ platform.

It's a work in progress which I'll leave as basic for now, and develop more if it benefits the HZ community.

I've also issued an asset on Horizon called "HZCHARTS" (id:17035415330002870030). For now, purchasing the asset should simply be seen as a way of supporting development of the site.  

I don't expect a big amount of interest yet thought it could be helpful to have a better overview of Horizon's Asset Exchange. There's a lot of junk / abandoned assets on there, hopefully it can improve!

Feel free to let me know you have any suggestions, bug fixes, or things you'd like to see.

Great new service!

Posted my kudos there. Will have a longer look after xmas.

Everybody, reward Emerger for this, every bit counts.

Good luck with that.
I have just bought some!

Great work.

Number 2, NHZDoge and number 3, NHZsphere in the list are not longer valid, because they have been replaced by HZDoge and HZsphere (23 and 26 in the list).

I bought some of your asset to support you.

[Emerger]

Thank you very much for the support! I am not yet sure what I will do with the asset, at this time it's simply a way to encourage me to develop the site, and every bit helps. In future I hope to have a chance to give the asset some additional value.

Right, the list of assets are simply sorted by total all time # trades. When I get a chance to do so, it would be better if I can order by 30 day volume or more a meaningful metric. The site is very simple for now.

I really appreciate the responses

I haven't bought your asset for profit, but to help you and an improvement of HZCharts.
It's more like a tip for your good work 

[altcointrader25]

you should include the assets description on the first page, as nobody has a clue what half of this stuff is and it's tedious to check page by page.

I too am a fan of nxtreporting, especially the consolidated "My Holdings / My Activity" view with drill-down into asset info. Having a similar consolidated "Portfolio" view for Hz coupled with a slate of high quality assets to chose from could only elevate Hz standing and appeal as a distributed asset exchange

As a show of appreciation and support for your effort I've purchased a small stake in HZCHARTS and look forward to seeing the project evolve.

I've added 30 Day Volume to the list of assets at http://hzcharts.coin.emergate.net so now it's much easier now to see which assets are being actively traded. Will update again here when I have had a chance to make any other major improvements.

Thanks for the support and ideas, I really appreciate it

Two ideas:


Link targets that somehow take into account the title bar.
Look at this example: http://hzcharts.coin.emergate.net/?a=getAsset&d=8101260088962758269#tradeHistory_wrapper
I am linking to that spot on the page, because that's where I can quickly see if new trades have happened.
But it scrolls a bit too far.


Address lookup, what about this simple temporary solution:
"Account page feature is incomplete. Please consider a donation. Until then, you can use the HZ block explorer on 16883723640155778764."

Nice find. I've added some anchors and adjusted for title bar. You should now be able to reach that trade history at http://hzcharts.coin.emergate.net/?a=getAsset&d=8101260088962758269#tradehistory

Thanks for this idea. I have added a very simple page for accounts (all work in progress) and also added contextual links to https://explorer.horizonplatform.io

If you are re-opening the HZxChange then I would like to point out that since some brief discussions with you last time I have started a simple site http://hzcharts.coin.emergate.net that summarizes assets on the HZ blockchain in realtime.

It has a simple api, for example:

to get a ticker for The HZxBTC asset:

http://hzcharts.coin.emergate.net/?api1=asset&id=5695508852370099719

or a ticker for the HZSHPRERE asset:

http://hzcharts.coin.emergate.net/?api1=asset&id=4033048123059509069

The vital data being the last price (in HZ) and 24 hour volume.

So using this api it is now possible to submit HZ assets to websites like coinmarketcap.com using their submission form.

And I'm thinking it may make sense to list all the HZxChange assets and currencies on coinmarketcap.com, once you are up and running.

Anyway, just thought to mention it. Anyone is welcome to use the api to list their HZ assets with coin listing websites.

If you need any improvements then the topic for feedback/requests is at https://bitcointalk.org/index.php?topic=1302140

Cheers!

Wow, great idea!

Especially to be able to list (some of) the assets at coinmarketcap ... can help to give the AE, and HZ more exposure.

Well done.

Three ideas:

* volume24h and volume30d, and perhaps volume90d or volume180d - because most asset trading markets are so much more sparse than centralized coin trading markets.

* I dimly remember that hzchronos had burned a portion of its asset shares. "Provably burned" should be possible to find out.
   Perhaps then subtract that amount from the total amount, and deliver as one more data aspect,
   perhaps "supply" versus "initial supply, or "unburned supply", or "remaining supply".

* coinmarketcap's request form allows to input:
    "Please provide a URL that shows the publicly available supply of coins in real time.
      These are coins that are not held by the creators or private investors."
  That is easy to calculate: from the total quantity (or from the above),
  subtract the asset shares that are still held by the issuer account, either privately, or in sell orders;
  then you get to the amount of asset shares that are really out there in the world, because people bought them.

Especially that last point is important, because already in my assetparser.py project I had noticed
that the "marketcap" (last trade price * total quantity) of some assets is gigantic, while
the "real marketcap" (last trade price * non-issuer-held-quantity) is really small, for most of them.

Good ideas?

[Emerger]

Thanks for your thoughts/ideas! Always good to get.

I've renamed the "volume" in the json to "volume24h" and "supply" to "total_supply". At least then it's clearer if we add more in future (as obviously, we shouldn't go changing the names once anyone is using it).

Looks like HZchronos burned them by sending to the genesis account: http://hzcharts.coin.emergate.net/?a=getAccount&d=13675701959091502344 Perhaps we can have it provide available_supply based on how many are owned by genesis account. If we look at the list of NXT assets on coinmarketcap e.g. http://coinmarketcap.com/assets/jinn/ I see that it does list both total and available supply separately. So I agree there is that need!

I'm not sure we need 30d volume in the json ticker. 30d volume is at least available on the main human-readable page. Although if you have a specific need for it to be in the json please say so.
For now I'm just interested in providing the bare necessities used by coinmarketcap and they only require 24h volume, as far as I'm aware.

I see what you mean with your last point, but with some assets the Asset Issuer is actively trading. Therefore I think all (unburnt) supply should be considered as publicly available, no? The only time I could see this as different would be with "Mineable" currencies on the Monetary System (and there aren't many of those, and not supported by HZcharts yet anyway).

I will think more on your comments and announce any important changes. Though you are welcome to bug me here if something you need urgently is missing
