因为cny长期超值，所以以往绝大部分的情况是内盘价是低于中值喂价的。取（中值喂价+内盘价格)的均价往往算出来会低于中值喂价。
既然喂价是内盘的喂价，就应当支持内盘，如果内盘的实际bts价格既（内盘价*充值费率）比较高，喂价就应当取这个价。为什么害怕内盘大户拉盘呢？你拉呗，喂价涨呗，只要充值费率是正的，喂价涨了很好啊。就算大户内盘砸盘，内盘价砸到外盘价以下，喂价就自动取外盘价了，这不很好么。

必须对猴子的玩笑有所戒备，机器人时代，巨变只在毫秒间，如果全体见证人都跟随内盘喂价，某个时间点，大户借出千把万瞬间把内盘拉到10块，然后喂价到10块，然后把债仓抵押最大限度提走，留下一个债仓等待喂价瀑布，然后。。。。

不是说不能取内盘价格来喂价，而是说必需对类似的极端情况有防护才行。

这样猴子就可以尽情抵押拉盘.

if 内盘修正价>1.1*外盘价
   喂价 = 外盘价
otherwise
   喂价 = max（内盘修正价，外盘价）

可以防止猴子拉盘了吧？

can't wait to change to this. you'd better update the feed price ASAP.
I will borrow enough CNY to pull the DEX's price to 10CNY/BTS or higher, when your feed price change to 10CNY/BTS, I can reduce my collactory to 1.6X, get another millions free BTS.
the big bad debt posision belongs to the system, to those who hold CNY, good thing is you have destroied the black swan, you just have a GS price protect at 10/1.6 CNY/BTS,

I suggest to take BTS/bitCNY price in DEX into important consideration, witness can firstly modify the DEX price with bitCNY premium/discount, then let this price be the bottom of feed price.

calm down bro, I just think that some witnesses can feed price like this, I am not suggesting that all witnesses should do this.

      要么给喂价设定一个底线，既不得低于（内盘价*鼓鼓充值费率）

这个可以有。

Guys, please calm down ...

Due to the use of "MEDIAN" in deriving the feed price on chain, you will **ALWAYS** .. let me repeat that: **ALWAYS**
find half the witnesses produce a price that is *above* the price feed and the other half to be *below* the price feed!!

I see, but the" MEDIAN" price is not a fair price, i don't think the price which come from the BTS/BTC price is a true fiat pirce, too many exchang and charge in there,  BTS-BTC-USDT(now6.93)-USD(6.7197)-CNY.

and i want to know what happened to the gdex-wittness, he is the highest in the last days, now he is the lowest！！！

If we can't make a professional feed price，how we can make a StableCoin？

gdex-witness is reviewing the price feed.

now I feel maybe the BTS/bitCNY price in DEX + bitCNY premium/discount got from magicwallet can result a fair price.

other ways always involve  some uncertain factors, for example, USDT is not so stable but it's not easy for the script to get how unstable it is.

General Discussion / [Announcement]Change of MSSR from 1.1 to 1.02 for bitUSD
« on: April 08, 2019, 10:55:31 am »
As the poll worker proposal 1.14.179 has been voted up, MSSR of bitUSD will change from 1.1 to 1.02.

The change will happen after  UTC 00:00 12th, April, 2019.

Every witness, please update your feeding script to publish 1.02 as MSSR of bitUSD, please do the job after UTC 00:00 12th, April, 2019 and finish before UTC 00:00 14th, April, 2019.

seems the cause is that recently USDT has a big premium, but some witnesses still calculate based on the normal USD/CNY rate.

Stakeholder Proposals / Re: [Committee Request] bitRUB == bitRUBLE (need to set the same parameters)

bitRUB now has only 500 supply, bitRUBLE is the RUB pegged assets which is mainly dominated.

shouldn't we just forget bitRUB and focus on bitRUBLE? do we need also to push bitRUB?

Would you print bitCNY if they had an force_settlement_offset = 0% and min_force_settlement_vol = 20%?

I conducted a survey in the russian-speaking community in Telegram, here are the results:



translation:
What symbol is more suitable for the currency "Russian Ruble" in BitShares?

90% RUB (was originally and conforms to the international standard ISO 4217)
10% RUBLE (was created after blackswan of RUB because of the lack of an asset revive mechanism)

84 votes

understand, then just let them equal.

I do not agree with the tone of the author, but some witnesses really did bad job in price feeding.

I am not referring to any specific witness, it's a generally speaking.

recently, I always feel that the market BTS/bitCNY price is a more exact BTS/CNY price than the feed price.

see below picture, market price is 2% higher than feed price, naturally you may think, does bitCNY has a 2% discount?



No. at the time bitCNY still have a premium of about 0.5%.

you may say that witnesses need time to response, so there's always delay when the market price change rapidly.

but what I see is that some witnesses do not update the price after 2+ hours or even 10+ hours even when the last feed price is 2% apart the market price.

I feel fortunate that months ago I disagreed to reduce the force settlement offset of bitCNY back to 1%, if it is 1% now it will provide chances for  speculators to exploit debt position owners!

I feel in the future we need to make a candle chart and put feed price of each witness inside for users to evaluate how exact the feed price is.

witnesses need to take the responsibility, it's important to the whole ecosystem, if you do not like the job, just leave and let others do.

To consider: The official ISO symbol if the russian ruble is RUB.

OK, maybe community would like to switch from bitRUBLE to bitRUB?
Anyway, it's good to set bitRUB parameters as same as that of bitRUBLE.

Stakeholder Proposals / [Poll] BSIP59:Reduce MSSR of bitUSD
« on: April 06, 2019, 04:56:06 am »
BSIP59 define a general process for adjusting MSSR and/or MCR through voting

bitUSD has already revived, now it's time to optimize the parameter to get better peg and supply, based on the principle of BSIP59 https://github.com/bitshares/bsips/blob/master/bsip-0059.md, now 3 poll worker proposals  are created as below:

1.14.178   Poll - BSIP59 - Reduce MSSR of bitUSD to 1.05
   
1.14.179   Poll - BSIP59 - Reduce MSSR of bitUSD to 1.02
   
1.14.180   Poll - BSIP59 - Do Not Reduce MSSR of bitUSD

Reducing bitUSD MSSR to 1.05 or 1.02 are both acceptable choice, comparatively, 1.05 is more conservative/careful,  1.02 is more active/aggressive.

As global settlement protection measure is already implemented through "1.14.176 Poll-BSIP58-Global Settlement Protection on bitUSD", the risk of global settlement is removed and we now just need to care the risk to enter "global settlement protection status".

please vote according to your opinion.

technically I am fine to do so. but

bitRUB now has only 500 supply, bitRUBLE is the RUB pegged assets which is mainly dominated.

shouldn't we just forget bitRUB and focus on bitRUBLE? do we need also to push bitRUB?

Stakeholder Proposals / Re: [Poll] BSIP59:Reduce MCR of bitCNY to 1.6
« on: April 05, 2019, 12:05:50 pm »
frequently changing MCR will put the ecosystem into danger.

don't request witnesses to play the role of economists, this is financial system, not a toy of anyone.

parameters like MCR, MSSR, force settlement offset need not to change every day, just as Federal Reserve need not to adjust the interest rate every day.

if you guys like the "dynamic MCR" solution so much, I suggest you to test it in some small smartcoin like bitEUR, just leave safety space to bitCNY and bitUSD.
