This thread is to replace https://bitsharestalk.org/index.php?topic=28265.0 (https://bitsharestalk.org/index.php?topic=28265.0)
Feed Price is so important that we need some mechanism to review/audit it.
If anyone in BTS community find that some witnesses do bad in price feeding, please provide proof here to show to all, voters should also get information from thread and decide to support or not support which witnesses.
In bitCNY price feed, I'd like to emphasize one principle，which get strong consensus from China community: the price feed should not conflict with the DEX price plus an bitCNY premium/discount offset.

this remind us that it's important to filter out the data which is inconsistent with real market, "the price feed should not conflict with the DEX price plus an bitCNY premium/discount offset" can be a good reference in judging the data from CEXs.

Time： UTC 9th May, 19:30
at the time in in huobi BTS price is 0.0507 USDT, USDT OTC price is 6.85 CNY fiat, then 1USDT = 1.004USD, 1BTS = 0.0509USD
this value is consistent to DEX price.

While we are at it, I started working on a python project that is supposed to automatically disapprove (unvote) witnesses that provide inaccurate feeds (relative to price feed) here:
https://github.com/xeroc/witness-monitor
Any development resources to improve that would be welcome.

that's great.
I also would like to have one tool to provide convenience to voters to estimate witnesses' work.
say, integrate all the price feed data from each witness to a candle chart, with modified DEX price, that will also help a lot.

only got round to accessing my feed script today just now.
My feed was actually the highest just now without changing anything a few hours later...I know we all wish BTS never moved down but guess what...it does....are we gonna have this discussion and people calling hard-working witnesses names EVERY time BTS moves down? Let me know so I can be prepared. It's crypto...it's volatile...it goes up and and it goes down. I don't like it either but it happens.
Still... I disabled the outlier CoinEgg component of the feed as it seems untrustworthy. Feed now 4% above median
-
I can't imagine what logic can be used to implement disapprove witness automaticly based on the feed price.
it's unresponsoble to vote witness automaticly by proxy, if somebody did this, please let me know.
BTW, did this development pay by worker income?

Again, our feeds are not every second. It's a price snap shot taken within some specific period 20-40 minutes (2 in your case) so it's an unreasonable statement based on some snapshot in time. price feeds should average out to a true price among all witnesses. Look at the screen shots later on, my price happen to be 2% above on the other side of that price medium is that a warning also?
And when will GDEX start feeding all prices? Should be unvoted by proxies until it does.

The feed price should provid within 5 minutes, within 3 minutes more better.
The pirce from specific period 20-40 minutes is a fake price.
BTS is a DEX, not MakerDao.
-
Most of the trading volume in the CEX is fake, and the trading volume in the DEX is already more than the actual trading volume in many CEX.The actual price of the DEX should be taken into account in the feed price.
-
Of course you need to have reasonable configuration. But surely, if a single witness publishes a feed that is 5% (or more) away from feed price, the proxy should at least be notified.
Unvoting a witnesses can be justified when the last feed was older than 2 days, or when he doesn't follow consensus when it comes to MSSR or MCR.
I wrote this code in my spare time, as usual ..

I don't think the higher feed price, the better, feed price should reflect the real market price. as feed price will have direct impact some operation, such as margin call, borrowing, force settlement.
it is not easy to judge what is "real market", but at least we can have some principles:
first, it is to get DEX price plus with smartcoin premium/discount as a reference, this is the most important reference.
second, it's not good to get average price of too long period and feed, an average of 5 min should be fine.

feed price should reflect the real market price, 20-40 minutes as price taking period is not acceptable.
"the higher, the better" is not my opinion. but now the main problem of feed price is some witnesses always feed too low price. we need to focus on this.
it's not difficult for me to request my coder to add feed price to all the smartcoins, but I am not sure that will make big sense.
taking bitEUR as one example, it has a supply of 57000 EUR and 24hour volume is about 4000 BTS, there are many users and important community members that come from Europe, but anyone care bitEUR?
if we really want to cultivate bitEUR, we need to consider to change something, such as MSSR, MCR, market fee etc., but seems no one want to do that.

Things to remember:
1. if price change is within a threshold (E.G. 0.1%, of course need to be small enough), to avoid chain bloat, it's better to skip feeding a new price. So it's possible that no new feed got published for a relatively long period, the reason is too little change in price. IMHO an average interval of 5~20 minute is good enough.
2. there were people crying in the past that "it's easy to dump in CEX to trigger margin calls in DEX". Come on, please put thick enough buy orders with your own money in CEX to prevent the price from dropping.
3. DEX price * premium? How to know how much the premium is? Volumes of the fiat gateways (MagicWallet/bitCNY:QC in ZB/bitCNY:CNC in AEX) are so low recently, which can not justify the premium. Also the gateway price (aka deposit/withdrawal processing fee) can change quickly.
4. volumes on many CEXs are FAKE.
By the way, we have some charts here: http://pricefeed-tracker.dex.trading/

I don't think this focus on the topic and a good talking.
You can you up?
Is it not a truth? or the design of feed price is perfect and not allowed people to judge it?

1、 There is a gap between the prices of BTS in various exchanges. Why is there no arbitrage?Because there are all kinds of handling fees.However, you witnesses did not consider handling fees for all kinds of conversion of BTS prices.
BTC--->BTS---->USDT----->CNY......
These price conversions do not take into account handling fees, so the feed price is always lower than the actual price.
The highest price of BTS in major exchanges (including the DEX) is closest to the actual price.
2、 Why can't the DEX price be taken into account in the feeding price? The volume of DEX has already exceeded tens of millions, surpassing many CEXs.
Is it because the price is difficult to determine?
How much does it cost for us to buy a BTS in the DEX? This is very clear,DEX price *Recharge rate.
This is the real price of BTS, at least the feed price cannot deviate too much from this price.
Why has MSSR dropped to 102%, and BITCNY premium is still large? The important reason is that the feed price is lower than the actual price.

People complained that witnesses updated price feed too fast when there is a dump happened on CEX. Now same people complain that witnesses updated price feed too slow when there is a pump? WTF?
Both longs and shorts are traders, we should treat them equally. That said, feed fair price, not too high, not too low. Don't change interval in downtrend nor in uptrend.

if DEX's price*premium>1.05*CEX's price
feed price = 1.05*CEX'price
otherwise
feed price = max（DEX's price*premium，CEX's price ）
premium=(Recharge rate+Withdrawal rate)/2

bitEUR, bitUSD, MSSR, MCR, should be adjusted at the same time, we have been well reflected in bitcny

Entirely disagree about trying to remove potential for discounts or premiums. Thats just the market. If the feed price moves and orders are still stuck at sub-optimal prices then there is an opportunity for takers to make money, thats intended. Regarding witnesses not providing accurate feeds ontime, thats also up to the market, if people dont like it they should vote out those witnesses.
I would see value in an open source script that takes as many datapoints as possible into consideration and publishes a feed with a comparison +/- % to others witnesses, perhaps post it on a webpage so voters can make the decision themselves to vote/unvote, apart from that nothing much else should be done.

People have two face, but if we have a reasonable and clear rules in the feed price, and remove the human factor from the witness, give the reasonable weight and parameter of CEX and DEX price, so some complaint must give a strong case.
The interval of feed price must have a rule.
Feed fair price, not too high, not too low, this is right, but some witnees was very hard to give the fair price, or too high, or too low.

it's easy to say political correct words like "we should treat shorts and longs equally", but I don't think these words get the key points of this ecosystem.
in BTS, shorts and longs(here longs means BTS long, means the debt position owners) are naturally not equal.
longs has an leverage tool to use, and at the same time bear the risk of margin call, and at the same time longs create smartcoin supply which is base of this ecosystem.
shorts does not.
so the rules should firstly be fair to longs, prohibit longs from being unfairly exploited, this is relevant to what we will build - a financial system with amazing stable coins or a gambling house.
that's why I emphasize the principle "price feed should not conflict with the modified DEX price(DEX price plus premium/discount)".
and I feel this statement is self-explanatory: "if a BTS/smartcoin pair in DEX has good enough market depth and volume, it should play the most important role in price feed determination."
because any CEX may have fake volume, naked shorts, etc., but DEX does not.
and because DEX is our home field.
this is not ignoring price in CEX, actually any big price change in CEX can be transmitted to DEX quickly, if price change in one CEX is not transmitted to DEX, it can be ignored.
it's reluctant to ask BTSer to put money to CEX to sustain the price, DEX should be the front that reflect the final short-long battle result.

if DEX's price*(1+premium)>1.05*CEX's price
feed price = 1.05*CEX'price
otherwise
feed price = max（DEX's price*(1+premium)，CEX's price ）
premium=(Recharge rate-Withdrawal rate)/2

otherwise

Please witness try to provide high feed prices within a reasonable range.
Now, if you buy a BTS in the DEX, the money that investors have to pay is the DEX price * recharge rate.This price is the actual price of BTS, why can't it be used as feed price?
Of course, in order to prevent being used by whales, the price should not deviate too much from the CEX price (e.g. 5%).
-
Please explain what "Recharge rate" and "withdrawal rate" is.
-
Please explain what "Recharge rate" and "withdrawal rate" is.
In China, if you buy BTS on the DEX, you mainly use a software ,name Magicwallet. In the software, there are acceptors who is responsible for buying and selling bitcny. first, you buy bitcny from the acceptors,and then you buy BTS from the DEX. Recharge rate is the handling fee for investors to purchase bitcny, and withdrawal rate is the handling fee for investors to sell bitcny. These two handling fees reflect bitcny's premium.
The higher the bitcny premium, the higher the recharge rate, and the withdrawal rate is even negative.
-
(1+ recharge rate)is the legal tender price for investors to buy bitcny in china.
-
(1+ recharge rate)is the legal tender price for investors to buy bitcny in china.
Thousands of our Chinese investors in the DEX(basically, the vast majority of DEX's traders) bought bitcny in this way, thus entering the DEX. DEX's price * recharge rate should be the most accurate price of BTS.
-
Thanks.
You're still ignoring the fact that there is a huge volume of poorly collateralized shorts out there, which means while BTS goes down the DEX price is permanently driven towards MSSR because of constant margin calling. Deriving the feed price from that skewed DEX price is what I'm primarily worried about, because it creates a dangerous feedback loop.
Also, I suspect that Chinese investors mostly do not invest in BTS, but they invest in BTC or other cryptos and use bitCNY/BTS merely as a vehicle. (I may be wrong of course.)
If large amounts of CNY enter the system that way, they will accept a worse-than-fair (less BTS per CNY and higher recharge rate) price, whereas when investors want to exit into CNY they will pay more BTS per CNY and accept a higher withdraw rate. Either way, the MagicWallet price will be skewed relative to the feed price. In a healthy market environment these differences would be resolved through arbitrage. Arbitrage is difficult here because of the general difficulty of investing CNY into cryptos. This only means that we must accept bigger differences, because with higher potential profits arbitrage will kick in at some point.
It is still debatable if the MagicWallet price reflects the fair price better than an external CEX. I see your logic there. At the very least though, the effect of margin calls on the DEX price must be taken into account.

what does CNY feed price mean? it means at which price you can do conversion between BTS and fiat CNY.
DEX price and bitCNY deposit/withdrawl fee in magic wallet is a good source to get such a price.
surely there are other ways, for example, the BTS/USDT price and USDT/CNY OTC price from huobi is also a good source to get such a price.
there may be price difference, but we should respect DEX enough as this is our home field, it is not acceptable that the feed price is much lower than the modified DEX price(2% or more), if you can really get BTS much cheaper than modified DEX price, please buy some and sell in DEX.

Funny thing is, at the current feeding price, there is basically no place to buy such a cheap BTS. Witnesses actually think that the feeding price is no problem.
For example, I bought 500,000 BTS in DEX last night. Each BTS cost me 0.404 RMB (2.1% of recharge rate is included). But the feed price is 0.395. Please tell me where the 0.395 BTS is available. Or which witness is willing to sell it to me at this price?

no ，you misunderstand. The feed price is the witness want to buy at the price. You should sell to them.

I can sell you BTS for 6.2 cents like gdex-witness feeds if you want :)

I can sell you BTS for 6.2 cents like gdex-witness feeds if you want :)
sorry, gdex-witness will check and update USD price feeding, however that's not the excuse for you to not feed well. :)

in my view, generally speaking, below are some principles to judge whether a witness feed price well enough.
1. feed price should reflect the price at which the conversion can be done between BTS and the pegged fiat.
2. feed price should be updated frequently enough to reflect the real market price.
3. for smartcoin with enough market depth in trading pair with BTS in DEX, such as bitCNY, feed price should not conflict with the modified DEX price, which means the DEX price plus the smartcoin premium/discount.

So we would get margin calls on DEX (with 1.01) which would be more expensiv than BTS at regular price on CEX ?
-
Other stable coins like bitEUR or bitRuble should also get a MCR of 1.6 and MSSR of 1.02.
@bitcrab: Can you initiate a vote for this parameter to other FIAT stable coins?

I think the user who use the bitEUR or bitRuble should think something more, because of these bitasset didn't have the Fiat gateways in DEX and didn't have the Fiat Trading pair in CEX.
How the user can detemine the quality of feed price? which price is the real fiat pirce?
But the funny things is the user of bitUSD seemed these didn't need to care about.
-
@binggo: For bitEUR price feed we can take a bitUSD price feed + EUR/USD exchange rate.
-
@binggo: For bitEUR price feed we can take a bitUSD price feed + EUR/USD exchange rate.
This is wrong.
EUR-USDT-BTC-BTS-BTC-USDT-EUR, there have some trading loss and charge, you take 1 EUR in maybe only 0.96 EUR out, the 0.04 EUR must count in the feed price.
If you want EUR chang to USD, you need to count the exchange loss and the charge.
It's not simple, and the feed price publisher must know these, if the feed price publisher didn't know these, please kill the stablecoin.

yes, maybe, when all the price is market price and bitCNY has a 1%+ premium.

Exactly. I hope all the witnesses can reach the consensus.

Complain XMAN, as a witness he has not updated the price for more than 22 hours.

I don't want say any "shit" words to these feed price, but if you can't provide a "fair" and "timely“ feed price and feel very hard, can you leave quietly and let other do this.
Can you explain where and how get these price?

Why not complain that gdex witness only provides 2 feeds? Why complain when witness doesn't meet >your< standards, when no standards are set? My feed as of right now is 2.1% off for CNY.
With no standard of measurement, you're complaints are meaningless. Besides, I am only 1 out of 21 witnesses, don't you understand how the price is set? 2.1% skews the median how much?
Your complaint is baseless. Better, you target witness that don't do the rest of their duties well, rather than complain about the few who don't always provide the feed the way you want it.

you just need to explain how your price is reasonable.
do you think the price feed is important for smart asset?
did you do the research of how to provide a reasoanble price?
you witnesses got a good paid from blockchain, you need to do some serious research in return.

feed price should not conflict with the modified DEX price, however at the above snapshot, you feed a price which is 5%+ less than the modified DEX price.

那既然是自由汇率那为什么脱离不了官方汇率很多呢？所以这是中外比特币的价格差，是由搬砖成本决定的，不是汇率差。
喂价应当反应的是bts与法币之间转换的价格，如果中间加上btc这一层，要把转换成本算上。
为啥btc/bts交易对的价格总是比法币交易对的价格低？环节越多搬砖成本越高啊。所以在主要交易所和内盘当中，最高价格最接近实际法币转换价格。bitcny和bitusd都应当用最高价，为防止价格操纵，可以加一个偏离顶，比如若最高价大于平均价超过5％，则不再上调喂价。

看了下这个平台就是FIAT USD，USDT和美元汇率就是1.0对吗？
可以认为人民币通过BTC交易换美元导致美元溢价了2.2个点，这样是可以解释内盘美元比人民币溢价2.2个点
但是我当时是按美元计价得到内盘美元喂价低了超过2个点，人民币喂价差不多。
你看看bingo在我后面几分钟的截图，人民币计价 0.4728，按1美元7.05算是0.067美元。
有没有可能你们的脚本汇率转换逻辑有问题，把0.067美元的BTS按 6.9 转成人民币喂价 0.4627人民币，再按 7.05的汇率算成 0.0656美元了？
所以当时的实际情况是人民币和美元喂价都低了超过2个点。

I've adjusted my feed pricing a couple days ago and have been monitoring the results. I hope you find it more in line with expectations.
I'd like to mention that depending on when you take a snapshot of feed prices it might not be an accurate representation of how well any witness it tracking price, with regard to how often a feed script is checking for price changes. For example if taken just after a significant price movement it might appear that some prices are off from where they should be. Where as, if given more time (at least 1 hour), their feed price script will make the appropriate adjustment. We are looking at many different markets also, so picking a time where all of these have been relatively stable for a period of time would be important for having a snapshot be an accurate representation.
I'm not saying this applied to my feeds abnormal prices, just wanted to mention it, as it might for some look worse than it actually is.
I'm currently only checking once an hour for price changes due to certain free API limit restrictions. As far as I understand it, this is still adequate. Please inform me if this is no longer considered acceptable.
After looking at my feeds, I found it was in fact a bit off and needed attention. I'll continue to keep a closer eye on this. Thanks everyone for paying attention.

其实多数情况下，人民币与美元喂价基本都会低1%左右，部分情况下会低到2个点，甚至超过2个点，很少一部分情况会略微低0.5%，汇率换算及转换损耗需要及时注意，而且外盘BTC及USDT交易对的深度明显都不足。
从另一个方面来看的话，bitCNY现在MSSR=1.01，如果喂价偏低，会使MSSR变相偏大，进而影响内盘价格，最后再影响手续费。

Indeed, but I don't believe after reviewing bitcrab's link to the "standard" he is using takes such things into account. His "standards" are simply not comprehensive enough, but that doesn't matter to him apparently, or do other factors that should be concerning the witness role, such as the number of feeds a witness provides, or how frequently they are updated, to say the least.
When I check my feeds most of the time they are < 0.1% from median. When they are checked makes a huge difference. If they are off at certain times are they off enough to skew the median by a significant amount (do my "bad" feeds skew the median by more than 1% ?) I seriously doubt it. The charts on the page in black, how are they calculated? Which exchanges / sources are used? How often are they sampled?
Just throwing up a chart of some numbers to rank witnesses' feed accuracy without that info is not helpful. If that info is available consider publishing it for the benefit of the entire BTS community.
The tool I rely on is RoelandP's witness log: https://roelandp.nl/bitshareswitnesslog/ (https://roelandp.nl/bitshareswitnesslog/) As of this moment my feed for CNY is only off by 0.05 BTS from median price, that's less than $0.0034185, and that is just one witnesses' influence. Calling for witness unvote for such small deviations is a witch hunt and is ridiculous. Not surprising to see such behavior from you tho. I am surprised to see alt agreeing with bitcrab tho.

0.05bts?
your feed price: 0.4733cny*0.05bts=0.023665cny, i don't think it is a small influence, you have more 2% influence than fiat price.
Now the fiat bts price is: 0.485cny, can you explain how you got the 0.4733cny?
Later you give a feed price 0.4725cny?! please explain?
If they are off at certain times are they off enough to skew the median by a significant amount
This is what‘s your thoughts? please don't so childish.
Do you know what's the difference between the two USDT Price? why one is 0.48147? and why one is 0.47094?
Do you know what's the difference between the two BTC Price?

median does not mean correct.
the median of a mess is also a mess.
it's not difficult for one user to find what a value is correct at a moment. only when every witness' feed price is good enough the median can be a dependable value.

Then one of us is definitely wrong, and I don't think it's me. Abit has commented as have others about the nature of the median price calculation. We use the median price, not an average for the very reason to exclude large influences by individual witnesses.
This leads me to think you're only trying to manipulate prices / trades through your pushing your perspective. It wouldn't be the first time you've done that.
@binggo, I didn't understand the calculation you made in which you claim my feed prices affects the median by more than 2%. I will study it more to try to make sense of it and will comment about that later.

The price of DEX should be an important criterion to measure the accuracy of feed price.
When Bitcny is not devalued, the feeding price should not be lower than the price of DEX. But in fact, this often happens, and that's why people complain.
-
What's a ashamed feed price? can you feel that?
It's a shame for the BITasset and BTS holder.
If you can't find out what's wrong with your feed price, please don't feed it.
And this also said to some big voting Proxy, please don't act like a zombie.

Greetings to Alt and the BTS community members,
Sorry for the late response to this situation and here is my explanation. On May 31st, bitcrab @ me in wechat group about the price feed issue and I responded immediately saying "I will check it" (see the figure below).
(https://ae01.alicdn.com/kf/HTB18lFDbv1H3KVjSZFBq6zSMXXab.jpg)
So I started to check my price feed script, which seems like the CNY to USD exchange rate caused the issue so I started to find more reliable API of currency exchange(I used the paid openexchangerates) and find if there is any logic bug can be fixed during the calculation of exchange rate. At the meanwhile, I was planning to add the premium between dex and external exchanges as a factor which is taken into consideration as a hotfix, to calculate the final price feed. However, when I first added the premium factor, I mistakenly messed up with its signs, but I found and fixed it immediately. So that's why there is a screenshot shows that the difference between my price feed and the median price feed reached 5%. In fact, this situation might not last for more than 10 minutes. You can see that bitcrab kindly reminded me about the issue at 13:47 and the screenshot about a 5% difference showed up around 14:00 when I am fixing. Finally, my price feed seemed like working well according to my observations later on that day(I am also constantly observing the price feed these days).
Since I thought that my price feed had been back to normal, I did not go to bitsharestalk to check if there was any new discussion about the price feed on the forum that day. And when I found this thread and prepared to respond, I found I cannot get the verification code to post unless *you know it* and due to the current network status(*you know it*), I failed a lot of times. Thus, I missed the in-time response to your question. I am extremely sorry for this and I promise that I will check the forum more frequently in the future. In fact, I really care about the price feed that I check it periodically and I also make quick responses to any changes decideded by the community consensus, e.g., MSSR.
This is my explanation about this event. I apologize for it again and I would be much appreciated if you can re-vote me again. Of course, any advice and suggestion from you and the community are thankful too. I will continue improving my price feed script. I hope we can make Bitshares much better.

Feed price is too important for DEX. If the bitcny is at a premium and the price of the DEX does not fall, the feed price should not fall.
The price of DEX is often suppressed by feed prices, but the rise of DEX does not push up feed prices, which is why we are angry.

看了下这个平台就是FIAT USD，USDT和美元汇率就是1.0对吗？
USDT:法币USD 的历史价格，可以参考这个图 https://trade.kraken.com/markets/kraken/usdt/usd
这个是USD法币和USDT直接交易的交易对。
最近还比较稳，在 1.0 附近
可以认为人民币通过BTC交易换美元导致美元溢价了2.2个点，这样是可以解释内盘美元比人民币溢价2.2个点
按我的历史数据，USD：CNY 在 7.0到7.1x都出现过，并不是稳定在7.05，更不是6.9。
也就是说USD相对官方汇率的溢价在1.5-3范围波动。
但是我当时是按美元计价得到内盘美元喂价低了超过2个点，人民币喂价差不多。
你看看bingo在我后面几分钟的截图，人民币计价 0.4728，按1美元7.05算是0.067美元。
有没有可能你们的脚本汇率转换逻辑有问题，把0.067美元的BTS按 6.9 转成人民币喂价 0.4627人民币，再按 7.05的汇率算成 0.0656美元了？
所以当时的实际情况是人民币和美元喂价都低了超过2个点。
binggo的图，你说的是这个吧：https://bitsharestalk.org/index.php?topic=28383.msg331008#msg331008
我看了下，那几个图是分别截的，第2/3个图明显时间戳差了十几分钟，第一个图看不到时间戳，不知道什么时候截的，感觉没法对比。
况且，第一个图是第三方行情站的图，行情站的数据采集是有延迟的，可信度不如直接从交易网站截图。
像下面我的截图这样，把所有网页窗口排在一起截的，都是一个时间点，就好算一点。
再说算法，你觉得你发帖的时候，人民币喂价差不多，这个帖子里
https://bitsharestalk.org/index.php?topic=28383.msg331007#msg331007
中间喂价 0.4640 你感觉是认可的？
你按 6.9 算的话usd喂价应该是 0.464/6.9 = 0.067
我当时的喂价是 cny 0.4637 usd 0.0652
也就是说 usd/cny = 0.4637/0.0652 = 7.11 比 6.9 差了近3个点，但逻辑是对得上的
@alt
为什么CNY：USD交易价格在7以上，而不是“官方”规定的6.9？因为“官方”汇率是被操纵的。而加密货币交易市场是自由的。
我的上次喂价：
Kraken BTC 报价 8550 美金
Bittrex BTC 报价 8549 美金
ZB BTC 报价 60241 RMB
AEX BTC 报价 60284 RMB
综合结果：
人民币：美金 约等于 7.05

USD的喂价其实也不高，因为还要看实际法币USD的进场是否流畅，还是通过USDT来转换，USDT的出场费用等。
每个地区的实际交易者才对实际的法币价格有深入的了解。

喂价应当是在本地购买bts所花费的法币数量。否则国际汇兑损失，交易手续费，等等，是很贵的，不计算进去，价格差就会很大。这就是为啥我们内盘投资者总觉得喂价低了，我们花的钱不止这个数啊！
bitcny的喂价应当是“在中国购买一个bts需要的人民币法币数量”。
bitusd的喂价应当是"在美国购买一个bts需要的美元法币数量"。
这中间所有的手续费都应当算上。
如果觉得难以采集数据，那就用最高价原则加上偏离顶，最高价最接近实际价格。
mssr已经是1.01了，理论上充值费率不应当超过1％过多，现在快2％了，就是说喂价还是比实际价格低了一点。

高不高，要看当时的行情。截图USDT只是参考。

这么简单的问题也不需要1小时出一次喂价对比.
国外的见证人按照USD的价格来官方汇率换算成CNY的价格，那我们也按照我们可以使用的法币价格倒推过去，
现在法币cny的价格是0.430cny/bts，官方汇率是6.9076，USDT汇率是7.13，
按照官方汇率：bitusd的喂价就是：0.430/6.9076=0.06225。bitusd的现时喂价是0.061008，交易所USDT价格是0.0595
国外喂BITCNY的价格是低于法币价格，我们喂BITUSD的价格其实是高于USDT价格，等于实际USD价格。
另外一点是USDT在tether的充入费率是0.1%，提现费率3%。
高不高，要看当时的行情。截图USDT只是参考。

这位兄弟，这个感觉比较冤枉。。。我这几天一直在修改喂价脚本，最先的思路是引入内盘权重，这个方法在横盘时都还比较正常，但是遇上这两天暴跌都是从内盘开始跌，就比较无力。后来感谢论坛各位的提醒，发现了根本原因，不能用美元-人民币的银行汇率进行计算。所以赶紧再次修改脚本，现经观察已经恢复正常了。不过也感谢你的监督啦，大家都希望比特股变得更好 :)

内盘价格做权重，必须做上下价格保护，喂价规则起码是这样，：
偏差率=P
喂价=内盘深度加权中间价*权重+外盘深度指数价格×（1+P）*权重
设一个上下价格保护: 外盘深度指数价格×（1+P）<喂价< (1.05+P）×外盘深度指数价格
P按照历史喂价的偏差数据看，一般在2%左右，可以按照自己的喂价与实际法币价格偏离情况进行调整。
这样就算是你按USD的官方汇率换算，内盘深度价格做大权重，你的喂价在极端情况下也不会偏离出多少。
这只是针对BITCNY的喂价， 其它的锚定资产需要另讨论。
或者是这位哥哥的：
if
max（DEX*溢价、CEX1、CEX2……）≤ Average（DEX*溢价、CEX1、CEX2……）*1.05
feed price=max（DEX*溢价、CEX1、CEX2……）
otherwise
feed peice=Average（DEX*溢价、CEX1、CEX2……）*1.05
控制喂价下跌的速度，防止插针。
if
feed price(n)*0.97＜feed price(n+1)<feed price(n)
feed price =feed price(n)*(1-0.5‰)
otherwise
feed price=feed price(n+1)
另外必须是深度加权中间价格，即时成交价有时候太坑。

解释一下我的方案。
一、最高价原则，设偏离顶。
if
max（DEX*溢价、CEX1、CEX2……）≤ Average（DEX*溢价、CEX1、CEX2……）*1.05
feed price=max（DEX*溢价、CEX1、CEX2……）
otherwise
feed peice=Average（DEX*溢价、CEX1、CEX2……）*1.05
二、控制喂价下跌的速度，防止插针。
假设n时刻的喂价为feed price(n),n+1时刻的喂价为feed price (n+1），当喂价剧烈下跌的时候，我们应当让喂价下跌慢一点,速度均匀一点。
if
feed price(n+1)<feed price(n)
feed price =feed price(n)*(1-0.5‰)
otherwise
feed price=feed price(n+1)

引入内盘价权重确实会遇到很多坑，感觉是个双刃剑问题。它一方面确实能解决横盘时期"喂价压着bts价格"的问题。但是另一方面，遇到暴跌行情，爆仓单一压着，又会造成"喂价拖着bts价格往下走"的情况。所以我现在暂时又将内盘权重移除了。
设置各种逻辑和上下价保护确实可以一定程度解决内盘权重的坑，但是我有一些顾虑。第一，我觉得脚本还是要遵循剃刀原理，如无必要，无需增添。现在通过各外部交易所加权取CNY喂价，有从CNY-QC-USDT-BTS这么个途径取得bts-CNY的喂价，也有类似于AEX直接取CNY-CNC-BTS这个途径取喂价，经我观察已经能够较好反应真实情况，那个人认为就不要再加更多复杂的规则了，因为有的时候系统越复杂反而漏洞越多。第二，加规则我觉得还是有人为因素。比如这个“偏差率p”，和"1.05"的问题，个人觉得可能会对喂价的客观性造成影响。
欢迎拍砖和继续讨论。当然我也会持续改进自己的喂价脚本。端午快乐

我感觉你们现在还不能理解老鼠拖着大象走的窘态, 以及未来内盘交易量远大于外盘时外盘喂价带来的致命威胁性.
在将内盘价格作为喂价权重的时候, 首先要清楚内盘是一个什么样的机制, 在这样一个抵押爆仓机制下, 内盘作为喂价权重在内盘价格下跌及上升时都有螺旋效应, 而所要做的就是需要避免这个螺旋效应, 但是不能因为这个螺旋效应就把内盘的成交量与价格一笔抹去, 这不正常.
所以就需要一个价格上下限来进行约束。
"偏差率"与1.05都是一些客观存在的东西，个人的主观因素起的作用有限，就跟强清补偿2%，MSSR=1.01一样。
最主观的因素已经在现在的喂价里体现的清清楚楚，为什么有人会拿着官方汇率来直喂并且到现在也不想改？为什么会有人采用币蛋的价格？
而且各个外部交易所的价格权重也是见证人自己设定，这也是主观因素。
用一些客观参数最大程度上摈除喂价提供者的主观因素与汇率影响，我们才能得到一个相对合理的喂价。
当然内盘价格作为喂价也有缺陷性，会导致爆仓频发，这就引申出另外一个规则“爆仓线与抵押线分开留出9%价格缓冲空间”。
我们拿bitUSD的喂价来看，abit说现在的bitUSD的喂价有些偏高，而实际上我们来看并不高，而且还有些偏低，USDT的有进出的充提费率，换过来实际上的USD的bts价格就是比USDT价格高。这个价格差异要么加到喂价脚本里，要么加到参数P上。
等有时间我们再去看看bitEUR的喂价，不在欧元区不知道他们的交易情况如何，不好断定。
喂价稍微高那么一两个点，影响不是很大，但是低上一两个点，带来的就是内盘的腥风血雨与充值费的大幅飙升，变相阻挡了资金的进入。
另一点就是： 取外盘交易所的价格要取深度加权中间价，不要取即时成交价格。
举两个实际的例子，ZB的QC交易对与AEX的CNC交易对，ZB永远在用小单刷买一，所以你取到的永远是买一价格，AEX永远是在刷卖一价格，所以你取到的永远是卖一价格。
引入内盘价权重确实会遇到很多坑，感觉是个双刃剑问题。它一方面确实能解决横盘时期"喂价压着bts价格"的问题。但是另一方面，遇到暴跌行情，爆仓单一压着，又会造成"喂价拖着bts价格往下走"的情况。所以我现在暂时又将内盘权重移除了。

现在内盘价又已经被喂价压下来了，感觉不出什么问题。但是上涨时内盘价格往往会比外盘高，且bitcny还在溢价状态，就像前期上涨时就出现了这种情况。上涨时喂价不考虑内盘价，就会明显压制多头，且内盘已经这么大了，不能总是老鼠拉着大象走。所以最高价原则还是很有必要的。
-
喂价稍微高那么一两个点，影响不是很大，但是低上一两个点，带来的就是内盘的腥风血雨与充值费的大幅飙升，变相阻挡了资金的进入。

不能这么说。
bitCNY的MSSR已经降到1.01，高两个点的话，就意味着爆仓单卖价比市场价还高，不利于风险消除，增加黑天鹅防护的概率。
当然，喂价低危害更大。首先需要解决的是喂价偏低问题。

as I observe, most of the time the median USD price feed is a little higher than reasonable.

huobi: BTS/USDT: 0.0609

based on above data, BTS/USD price at the moment should be about 0.0611. however at the time the feed price is 0.061522.
yes, it's only less than 1% higher, but I think we need to find something behind this data.
one thing is that the officially published USD/CNY ratio should not be used in feed price calculation, as CNY is still restricted in trading in currency market.
at the moment, the officially published USD/CNY ratio is 6.91， however from above data we can calculate that the ratio should be above 7.05.
-
BTS/USD price should be about 0.06208.
BTS/USDT price should be about 0.0609.
bitUSD:USD=1:1? or bitUSD:USDT=1:1?

我的见证人已经在喂价了，从这两天的结果来看，喂价还是比较准确的，Cny喂价基本上在+-1%之间波动，USD喂价基本上偏高1-2%，但是考虑到内盘汇率高于法币汇率，我提供的USD喂价较高也较为合理。

The Global Settlement happen at price is wrong.

You're correct.
I didn't enable GS protection on bitUSD.
Now enabled.

Please note that the "Global settlement happens at price" in the UI currently did not account for the MSSR values. This means that for bitUSD this value is 1.02 times higher. It's been fixed and pushed for next release.
The UI got two new enhancements to improve price feed monitoring by the community
- Asset page views wrong Global Settlement trigger price + Market Depth Enhancements (https://github.com/bitshares/bitshares-ui/issues/2945)
- Sortable Feed Table w/ offset (https://github.com/bitshares/bitshares-ui/issues/2947)

I suggest every voter to unvote witness sahkan-bitshares.
up to now this witness still feed MCR=1.75 and MSSR=1.05 for bitUSD, ignoring the poll voting result.

越来越低，dex里的bts才是真的bts，价格才是真的价格，为什么无视bts的真实价格，而选择cex虚假的甚至恶意的价格呢？！为什么要这么伤害社区伤害bts市值？
