在巨蟹的思想里，把当前bitcny最大的需求——内盘，忽略不计了，而总是想着如何满足当前几乎不存在的“外盘cny供需关系”。当前喂价向下调，效果不是使cny产出满足市场需求，而是不断消灭cny的市场需求。
更新。
当bitcny贬值时，通过下调喂价/提高MCR，会在没有爆仓的情况下直接触发爆仓，直接增加卖盘，所以事实上很容易修正贬值，甚至矫枉过正。
当bitcny溢价时，通过上调喂价/降低MCR，在有爆仓的情况下会直接减少爆仓减少卖盘，但是当锚定基本稳定时、没有爆仓时，不能直接减少卖盘，只能鼓励更多买盘或者增加债仓，对市场只是间接影响。
所以，两个方向的调整有效性/力度是不一样的，贬值时实际力度更强、溢价时实际力度较弱；
相应的，喂价脚本出现偏差时带来的副作用的也是不一样的，误判为贬值时对市场的负面影响更大，误判为溢价时对市场的负面影响相对较小。
从这个角度来说，喂价脚本对贬值的判断、反应要更谨慎一点，更温柔一点，步子迈小一点。
实际操作可以从几个方面改善：
1. 取内盘 BTS/bitCNY 价格时，取盘面最高买单价格，比取最新成交价好
2. 过滤小单
3. 判断为贬值时，喂价调整用较小比例；判断为溢价时，喂价调整用较大比例
4. MSSR可以调小一点，避免大波动
不过，前3点目前见证人可以自己调参数，第4点看来还需要社区共识（投票）。
记得实施反馈前讨论时有几个共识，无论怎么反馈：1. 喂价不能低于市场价；2. 主要目的在于增加流动性；3. 提升BTS的市值排名。好像这几点现在都没有实现。哪里有只能高不能低的共识，只能高不能低那还叫负反馈吗？前几天USDT崩盘被一些喂价程序解读为bitUSD溢价很高，造成一直提高喂价，现在是在回归正常。
没人规定交易所没有投票权，也没人能剥夺其投票权。
说的好，漂亮！

I use my right for free speech and expressing myself in the way i like to.
Let me make this very clear to you and everyone else, right away. This forum is operated by the BitShares Blockchain Foundation and as such lives under Dutch law.
Your 'free speech' has been granted to you by your government, is limited to public law and does NOT apply in this forum which is privately operated.
Consequently, you can (and will be) lectured by means available to the operator, if they so chose, in case you continue personal rampage. Your tone is unacceptable not just for this community and the desire to cooperate to solve current issues (which constantly change) but is also unacceptable for the internet as a whole.
Provided that I dont speak for the BBF, i cannot give you an official warning, but rest assured that this is escalated to the proper authorities.
So, please stick to basic netiquette or go somewhere else.
