中文(Chinese) / Re: BISP42 紧急修正案

woker 1.14.140 created, kindly vote if you support this.

108
as some time ago the voting power that oppose BSIP42 overcome that support BSIP42, most of the witnesses return to feed just market price, immediately the BTS/bitCNY price fall about 8%, although more margin call orders are eaten, but:

1. price fall continue, bitCNY holders seems to wait for lower price, no big will to eat current margin call orders.

2. bitCNY has a premium of about 10%, it's a disaster for bitCNY business.

3.more debt position margin called, not obvious margin call quantity reduction.

actually witnesses need to be careful while doing a big change, it is not a good behavior to just change while seeing the voting result - no one host/claim/announce the voting activity, it is likely that some balance owner change lead to this result, please be careful while seeing this!

here I propose to restart BSIP42, with adding some new logic:

1.add the black swan protection logic, ensure feed price >global settlement price*1.11

2.ensure feed price > market price.

3.ensure feed price < market price*MSSR

4. if 1 conflict with 3, ignore 3.

5.tolerate a -2%-1% premium, do not adjust feed price if bitCNY premium is in this interval.

this poll will be regarded successful if it get more voting weight than 1.14.119


(2) only in case of premium imho...

actually in Chinese community there's a lot complaints against the fact that feed price can be lower than market price, some think this hurt them by margin calling a debt position with enough collateral.

因为BSIP42投票刚刚反对票多过了支持票,于是一些见证人就直接改回了真实市场价喂价,导致内盘BTS价格瞬间跌了7,8个点,虽然帮助消化了一些低抵押率爆仓单,但是造成的恶果是:

1.价格再持续下跌,bitCNY吃爆仓单的意愿并没有足够强,期待更低价格的情绪明显。

2.bitCNY再次溢价10%,大家可以想象带来的恶果是什么。

3.喂价持续下跌带来了更多的爆仓单。

BSIP42投票有特定的计票日,即便要取消BSIP42也不应该采取这么生硬的方式。而且在现在这样的非常时期是需要BSIP42来提升活力并确保bitCNY供应的,我提议对BSIP42进行更新之后重新启动,更新如下:

1.增加黑天鹅防护,确保喂价 >全局清算价*1.11

2.确保喂价高于市场价

3.确保喂价低于市场价*MSSR

4. 如果1与3冲突,舍弃3

5.对-2%-1%之间的溢价作容忍,不更改喂价。

本投票当获得支持超过1.14.119时生效。

now I greatly propose: 
 
1. witnesses please restart BSIP42, however according to what we learn in the past, I suggest to add black swan protection logic, and ensure the feed price is not lower than market price and not higher than market price*MSSR.

2. please vote to support BSIP42.

3.start the process to draft updated solution to relevant issues.

BSIP42投票有特定的计票日,即便要取消BSIP42也不应该采取这么生硬的方式。而且在现在这样的非常时期,取消BSIP42如何做好过渡至关重要,当前,我呼吁:

1.见证人重启BSIP42喂价,但接受前面教训,喂价应该保证不低于黑天鹅保护价以及市场价,同时不高于市场价*MSSR。

2.社区投票支持BSIP42。

3.启动新版解决方案的制定。

巨蟹讲的有道理,估计难通过。那能否把上限定在20%?毕竟若就10%那就跟下调MSSR到0没区别了。
关于速率问题,我觉得CNY的允许波动范围应当能缓解下降速率。

有区别,调高喂价可直接增加可借出量,MSSR调为0没这个效果。

我知道。修正案的核心就是允许喂价在cny溢价的时候上调,往往是现价大跌的时候出现溢价。现在就是允许现价跌的时候,喂价在一定范围内不跌。喂价0.61的时候发生了现价大跌的情况,那时喂价不跌很好的保护了bts,没有造成连环爆仓。但是错就错在没有一定的折价容忍,使喂价缓慢下调。现在若只允许喂价高于现价一个MSSR,则连环爆仓还是会发生呀。至少应该比MSSR大那么一点吧。

不会,当喂价=市场价*MSSR的时候,爆仓单卖价也就是市场价,如果bitCNY有溢价那么爆仓单卖价比内盘价格还高一点点,带不来搬砖机会,也就没有连环爆仓。

gdex-witness plan to update feed price algorithm for bitCNY as below:

Code: [Select]
plan for next update on bitCNY:

Pdex:BTS price in DEX in smartcoin
Pf: current feed price
premium: current premium
GS_price: global settlement price

scale= 0.5;
get Pdex, Pf, premium, GS_price;

black_swan_protection_price = GS_price*MSSR*1.01

while True:
   
   get Pdex, Pf, premium;
   if 0.5%>premium>-1%: ##just adopt the current median if the absolute premium is low enough.
       feed price = Pf;
   else:
       feed price = Pf*(1+premium*scale);
   feed price = min(feed price, Pdex*MSSR)
   feed price = max(feed price, Pdex, black_swan_protection_price)
 
   time.sleep(120); ##update every 2 minutes.

keep the BSIP42 logic, added GS protection logic, ensure the feed price is higher than market price and lower than market price*MSSR

bitCNY now has a premium of 2%+, if removing BSIP42 logic, the positive feed back effect will make price even lower and bitCNY in a higher premium, that is a disaster that actually can be avoided.

hope big proxy can support this updated BSIP42 as a temporary solution for this special moment.

4很难执行,建议取消。
还有,建议把上调的范围限制在市场价*MSSR范围内,以防止爆仓单风险累积。
不好意思,上午在忙回复较慢。
感谢巨蟹的回复,若难执行,赞同取消4。 
   但现在MSSR只有10%,若只比市价高10%,根据以往经验估计对溢价控制的力度太小,若有这个限定,感觉负反馈就基本没效果了。根据以往经验,出现喂价大幅高于现价的情况并没有什么危害,只要CNY允许有波动范围即可,爆仓爆不掉,并不是喂价下调不够,反而是下调过快,没有时间搬砖,导致CNY在允许波动范围内喂价过分下调。

之所以现在有较大的反对声音,就是因为喂价高过现价太高,导致爆仓单价格比现价高不少,结果是爆仓单累积,直接增大了黑天鹅发生的可能性,现在这个时间如果不加上这个限制,感觉很难获得足够支持。
