Are the feeds acceptable now @alt? If not what issues are you still seeing we can address?

Updated price feed for SILVER, GOLD and CNY.
witness name: elmato


Offline wackou

I have updated my witness to publish correct values for both GOLD and SILVER. I also released bts_tools 0.4.6 which implements it (that's the version my witness is running). Be warned though that 0.4.6 has a bug that prevents it from building the client, but the monitoring and feed script part should work ok. I will publish 0.4.7 that fixes that shortly
Please vote for witness wackou! More info at http://digitalgaia.io

I have a ugly hack of @xeroc's script here:
https://github.com/abitmore/python-graphenelib/commit/d8f94b2d156fdc7f774acc72c7f821151af40df2

and this in config.py:
Code: [Select]
"derive_across_3markets" : True

//Update:
If you don't know what above changes will bring, oops.. they're made for producing relatively "more correct" gold/silver price feeds.

For a relatively "more correct" CNY price, if you're using @xeroc's script, you can have these lines in config.py (just add poloniex and bittrex):
Code: [Select]
"CNY" : {
                    "metric" : "weighted",
                    "sources" : ["btc38",
                                 "yunbi",
                                 "huobi",
                                 "btcchina",
                                 "okcoin",
                                 "poloniex",
                                 "bittrex",
                                 ]

16 days have passed, the price still wrong.
and there are 374 SILVER margin call just a moment ago
here is the feed price:

Offline wackou

I have now updated the feed price for gold from yahoo to use the correct value from here:
http://download.finance.yahoo.com/d/quotes.csv?s=GC=F&f=l1&e=.csv
as suggested by abit. This is implemented in the recently published version 0.4.5 of the bts_tools, which my witness now uses to publish adjusted feeds.

I plan a deeper refactoring of the feed script that will make it more efficient, more stable and more decentralized (esp. the reliance on yahoo), but that'll take a couple of weeks. Stay tuned!

Cheers!

Beautiful!  Thank you Fox!

GOLD can be an important asset and is worth supporting.  There are many who choose to hold savings in (real) gold, so having a stable and worthwhile SmartCoin which tracks the value faithfully is important.  Personally, I'd love to see GOLD supported as a method of payment (hello BLOCKPAY), or available on those crypto-credit-cards.

I have adapted the @xeroc developed pricefeed script included within the python-graphenelib repository:
Code: [Select]
https://github.com/xeroc/python-graphenelib
If you are using this script, you may use the steps below as a guide to provide valid feeds for gold and silver.

1.   Edit config.py to remove Yahoo as a feed provider for GOLD and SILVER (Yahoo is not providing a valid USD price at this time)
1.1         Locate the feedsources.Yahoo function
1.2         Comment out the XAU and XAG entries using the hash symbol
Code: [Select]
#"XAU"       : "GOLD",
#"XAG"       : "SILVER",

2.   Ensure Quandl is enable as a feed provider for GOLD and SILVER
Code: [Select]
feedSources["quandl"]    = feedsources.Quandl(datasets={  # You provide a valid API Key or this will fail!
                                                  "GOLD:USD": [
                                                      "WGC/GOLD_DAILY_USD",
                                                      "LBMA/GOLD",
                                                      "PERTH/GOLD_USD_D"
                                                      ],
                                                  "SILVER:USD": [
                                                      "LBMA/SILVER",
                                                      "PERTH/SLVR_USD_D"
                                                      ]
                                                  }
                                              )

3.   Acquire a Quandl API Key
3.1         http://help.quandl.com/article/118-how-do-i-pass-along-my-user-id-or-api-key
3.2         It’s free, but requires a valid email account, GitHub account or other authentication provider

4.   Edit config.py to add your Quandl API Key
Code: [Select]
quandlApiKey = "dsahFHUiewjjd" # This is an invalid API Key. Replace with yours!
5.   Edit feedsources.py to include your Quandl API Key
5.1         Locate the Quandl URL string:
Code: [Select]
url = "https://www.quandl.com/api/v3/datasets/{dataset}.json?start_date={date}.format(5.2         Modify the query string portion of the URL to include your API Key from the config.py file
Code: [Select]
url = "https://www.quandl.com/api/v3/datasets/{dataset}.json?start_date={date}&api_key=" + config.quandlApiKey.format(
These modifications should allow your witness to provide a valid feed for both gold and silver.

I know others are using the scripts from the @wackou provided bts_tools repository:
Code: [Select]
https://github.com/wackou/bts_tools
I quickly glanced at this codebase, but did not locate Quandl as a feed provider.    I will endeavor to scratch together some code for bts_tools as well.

Due to unable to provide a forever accurate price feed, or no time to track whether they're correct, I'll stop producing price feeds for assets other than CNY/BTC/USD/EUR and their copies e.g. TUSD. IIRC actually I've never supported the assets with next to zero activity. It's my fault to provide price feeds for them.
maybe we can't stop publish price for GOLD/SILVER unless all short positions quit.
Just let them trigger a black swain event or something similar. We lack of resources, we need to focus on the popular products.

bitGOLD/bitSILVER are among few actually traded bitassets, and it would be sad if they go down.

It may be fair to note that most witnesses have been working practically ad honorem for between one and three years with such a responsability, the most with almost 24/7 avaibility to take care of the network.

Fetching a price sometimes fails due to source API problems. Sometimes it requires small modifications in the script to keep working. Some times the whole logic of the script had to be renewed.

But this is no excuse, we have to fix this asap.

I agree with abit on that stoping a low volume market is better than risking its users and the whole network with wrong feeds.
His decision looks to me as a call for attention.


It looks like only four witnesses are fetching gold and silver prices from sources other than yahoo.

For a fast short term correction, have you tried adding a quandl API key to its URL?

just wanted to chime in and say that, as a witness and feed script provider, I will update/fix/do whatever is necessary to produce correct feed price for GOLD (as well as for other assets) but as most other people I am currently on holidays with the family, so it will have to wait a week or so.

Yes, I’m relatively new here and yes I can be abrasive.  And no, I don’t really know who the important players are.  But, I thought I had found something special in Bitshares: a professional-grade network, and many robust features ensured by delegated proof of stake.

I’m sorry, I just don’t understand why abdication of responsibility shouldn’t have consequences for something as important as the witness.

Being a witness in Bitshares is the foundation of a secure network and is the primary mechanism to ensure that Market Pegged Assets (aka: SmartCoins, or bitAssets) function as intended.  Without responsible witnesses (and a community voting to ensure it), the Bitshares ecosystem is less enticing for use and investment.

I mean no disrespect to abit and his many contributions to Bitshares.  It’s just that running a witness node should not be viewed as an ‘inconvenience’ — many will gladly take the job for the important one that it is.

A professional network requires professional witnesses.

And that includes GOLD.  Please don't throw up your hands and give up when someone suggests an improvement.  Work to fix it!

Wait.  WHAT?

Really, that's your attitude?  Jeez, let's vote this guy out and find a new witness who actually cares about Bitshares.

EDIT: I mean, really!  If you're not prepared to handle the responsibilities involved with being a witness, there are many others who can step up and fill that role.

Bitshares is a business.  If anyone is incapable or unwilling to do their JOB, it should be given to someone who will.

An asset is only worth what someone is willing to pay for it (free market supply and demand): even if Yahoo, Google, BTC exchanges or some Government says otherwise.

These sources don't make the price. They just report the market price, which is supposed to be fed to bitshares by witnesses to peg bitAssets to it.

This "free market" argument is irrelevant here. Bitshares is a free market, which needs an accurate price feed from trusted sources to function.

If you peg bitGold to something other than gold, it does not make sense.
yes I agree even though its a ridiculous argument.

Price feeds are what makes settlements and margin calls work as intended.
yes I agree with this too.

My point is in relation to the OP "who can tell me what's the GOLD price?" :

The true price of bitGOLD, bitSILVER, bitUSD, bitGBP, bitCNY bit...

is what someone is "willing to pay" for the assets on the BitSharesDEX or external exchange.

Price feeds are a reference for guidance.

Price feed is not just reference for  guidance, it is the price these coins are supposed to be pegged to. If you peg bitGold to something other than gold, it does not make sense.

thanks to clarify this.

I agree the price feed is witness's responsible, they got paid for that. anyone others never have responsible to help these witness.
wish you can remove your vote for those witness who can't give a reasonable feed price, who don't take responsible.
I prefer 9 witness with responsible instead of 25 witness without responsible

Witness is not only a part job, but a glorify. kick the lazy witness out.

Well .. witnesses are paid for providing blocks and witbessing a correct price feed .. the definition of 'correct' of cpurse depends on the markets look at for generatimg the feed price they publish.
Either way i am looking for sone witnesses to produce more professional feeds as my 'script' was always ever meant for educational purpose and not for productive use (see script header) ..

there are about 390 SILVER will be margin call when BTS price dumped to 0.004USD/BTS
in fact his real margin call price is 0.0034USD/BTS

and he has to bought 390 SILVER at price 18.7USD/SILVER instead of 15.7USD/SILVER

I'd like to know if it's fair to this guy

if you witness don't know which price is fair, just stop publish the shit.
no price is good than wrong price

seems nobody care about these shit MPA
maybe most people still waiting for  BM to give an order

if anybody care about these , please set up a new witness, prepare the feed price, and I will give my vote.
You are being unfair here ..
anyways, i agree that witnesses should take more responsibilty about the prices they publish .. i gavw them all the tools they need with FOSS code and dont see that its my duty to do anything here given that a dont run a witness or anything

The code also uses google and quadl and can easily be extended to any other source .. bit i persinally will not pay for professional feeds because i dont run a witness ..

There is no SINGLE PRICE of anything.
It all depends on the subset of buyers and sellers that define specific price on a specific trade. Fortunately, we have some bigger exchanges that have a ticker for those trades.
Unfortunately, we have many of them, some bigger, some smaller. Each exchange has there own price. In fact, every trade has it's own price.

In this case, do we need to be more specific when we create a bitAsset about which index will it be pegged to, like yahoo gold, poloniex BTC, etc?

This is really weird. At first I thought Yahoo was showing an ETF price, but it really looks like it's gold spot vs USD. I can't find any reason for its higher price than the rest of the world, except that for some reason it's not able to be arbitraged properly. Not sure why.

But anyway, I can confirm that most of the world is trading on the 1130 spot price. A quick search around the internet reveals this. Example: https://www.bloomberg.com/quote/XAUUSD:CUR

so we're all wrong?
all the witness published the wrong price
what's the meaning of the price from yahoo finance and what's the meaning of bitGOLD?
fuck myself, shit witness, what should we do to correct this?

1130 of course.

Not sure what it means, but this is from the second site that you gave :

GOLD 1 OZ (XAUUSD=X)
CCY - CCY Delayed Price. Currency in USD
