建议分离爆仓线和抵押线 讨论~~
« on: September 25, 2019, 02:24:39 pm »
以下是我对于分离爆仓和抵押线的一些看法

FP  即喂价      CR  抵押率       MCR  最低抵押率         maximum short collateral ratio  (MSCR)  爆仓抵押率       MSSR  爆仓惩罚比例   

内盘现在贴线抵押猖獗,贴线抵押在价格下跌时,往往就会造成踩踏事件,空头会挂单在爆仓单以下,造成价格越来越低,同时爆仓单的价格越来越低,
由此引发更多的爆仓单,现在爆仓线和抵押线没有分离,价格下跌2%既会出现爆仓单,因为MCR的连续性,爆仓单通常都是一串一串的。所以我们进行隔断。
MCR限制调整参数最小为0.1  MSCR不变

因为现阶段目前 MSCR 和MCR  是在一起的 因此我们从MCR中分离MSCR以增强稳定性,


如果我们把MSCR 和MCR 进行分离隔离  MCR设定固定区间 1.6-6.0  同时调整最小单位为0.1 既1.6-1.7-1.8-1.9~~~6.0 
区分后的MSCR设为1.50 ,

此时我们假设FP为1cny=1BTS

大量用户A  持有并抵押1000000  BTS  设定CR为1.6   
大量用户B  持有并抵押1000000  BTS  设定CR为1.61
大量用户C  持有并抵押1000000  BTS  设定CR为1.62

加入没有更改之前  当价格下跌0.65%时 大量用户A开始爆仓同时危及大量用户B,当价格继续下跌0.65%时大量用户B开始爆仓同时危及大量用户C

加入我们按照之前的分析 分离MCR与MSCR 另外进行限制最小调整单位为0.1时

此时我们假设FP为1cny=1BTS

大量用户A  持有并抵押1000000  BTS  设定CR为1.6   
大量用户B  持有并抵押1000000  BTS  设定CR为1.7
大量用户C  持有并抵押1000000  BTS  设定CR为1.8

当价格下跌6.25%时 大量用户A开始爆仓

大量用户B的 MCR 还维持在1.59左右,只有当价格继续下跌6%左右才会开始爆仓

大量用户C 的MCR依然在1.59左右 只有当价格继续下跌5.6%左右才会开始爆仓

这样区分开了爆仓,设置了爆仓缓冲,增加了稳定性,还有适当提高了做空的难度

如果我们创造抵御做空者的手段,我们就无法更好的上涨。

Here are some views on my separation of the warehouse and the mortgage line.

FP is the price
CR mortgage rate
MCR minimum mortgage rate
Maximum short collateral ratio (MSCR)
MSSR burst penalty ratio

The inner disk is now affixed to the mortgage line. When the price is lowered, the mortgage will often cause a stampede event. The short position will be listed below the short position, resulting in lower and lower prices, and the price of the short position is getting lower and lower.
As a result, more burst positions are triggered. Now the explosion line and the mortgage line are not separated. The price drop of 2% will result in a burst order. Because of the continuity of the MCR, the order is usually a string. So we need to cut off.
MCR limit adjustment parameter is at least 0.1 MSCR unchanged

Because MSCR and MCR are currently together at this stage, we have separated MSCR from MCR to enhance stability.


If we separate the MSCR and the MCR, the MCR sets a fixed interval of 1.6-6.0 and adjusts the minimum unit to 0.1. 1.6-1.7-1.8-1.9~~~6.0
The differentiated MSCR is set to 1.50.

At this point we assume that FP is 1cny=1BTS

A large number of users A hold and mortgage 1000000 BTS set CR to 1.6
A large number of users B hold and mortgage 1000000 BTS set CR to 1.61
A large number of users C hold and mortgage 1000000 BTS set CR to 1.62

Before the addition, there was no change. When the price fell by 0.65%, a large number of users A began to explode while jeopardizing a large number of users B. When the price continued to fall by 0.65%, a large number of users B began to explode while jeopardizing a large number of users.

Join us according to the previous analysis, separate MCR and MSCR, and additionally limit the minimum adjustment unit to 0.1.

At this point we assume that FP is 1cny=1BTS

A large number of users A hold and mortgage 1000000 BTS set CR to 1.6
A large number of users B hold and mortgage 1000000 BTS set CR to 1.7
A large number of users C hold and mortgage 1000000 BTS set CR to 1.8

When the price fell by 6.25%, a large number of users A began to burst

A large number of users B's MCR is still maintained at around 1.59, only when the price continues to fall around 6% will start to burst

A large number of users C's MCR is still around 1.59. Only when the price continues to fall by about 5.6% will it start to burst.

This separates the bursts, sets the burst buffer, increases the stability, and appropriately increases the difficulty of shorting.

分离开的最大预期是反弹形成的缓冲区,从而在一定程度上抵御突然的做空攻击,但是最后还是可能形成临界点。

我认为如果能够将选择的权利交给用户,并且避免这种临界效应为最好,或者用其它的方案来相当程度上代替这种分离,抵押者只需要付出很少的利息来抵御做空攻击:
比如类似这种:
https://github.com/bitshares/bsips/issues/182
或者把这种方案简化一些,到时候抵押者,锚定资产持有者,bts持有者都可以从中寻找自己的利益空间。

当然我设想的这种简化方案最后还会形成一定的临界效应,比如到1.35才爆,最后价格下降都挤到了1.35就比较尴尬。

当然最激进的方案就是共同抵押率,这样怎么也不会爆,唯一的问题是抵押者付不出利息,而自身抵押率又低于MSSR, 这样就不是太好处理

两线分离,早就该做了。
