There was active exploiting that uses inaccurate price feed and generates free money for the exploiter.

we talked in the past already about inaccurate price feeds a lot.
It is not just an inaccurate price feed as in a feed with fluctuating price but a feed with a consistently wrong CNY price due to the fact that the algorithm does not pull in any China website sources. It is like getting USD fiat prices not from the USA but from some other non-related places. This price figure is simply wrong and cannot be relied upon. And no matter how you want to call it, the price feed script is flawed. The flawed price feed in the DEX allowed opportunistic flaw exploiters to gain unfairly at the expense of one side of the long-short players.
The rest of the points are really out of the scope of the proposal. But for the sake of completeness, let's discuss them.
i wanted to have them as good as possible. with metaexchange we had the problem in exchanging bitBTC - BTC .
claiming not working pricefeeds - hurts only shorters, so i ask transwiser direct - why are you holding CNY shorts?
not working pricefeeds will happen again and again and if transwiser justs holds CNY and bitCNY it is not their concern.
it was also already stated - force settlement is in the command client since the beginning, so nothing new here at all.
this reaction tastes not good in my mouth.
the committee saved some speculators and hurt other speculators.
Out of Scope Discussion
=========================
As you said it, metaexchange "had the problem in exchanging bitBTC - BTC". AFAIK, nobody - absolutely no businesses are pegging 1 bitBTC : 1 real BTC in the bitshares DEX. But why? IMHO, the risk of losses is probably too high to justify any profit.
Transwiser, on the other hand, is literally pegging 1 bitCNY : 1 CNY (with a small fee) and offering this bitCNY to CNY fiat onramp and offramp services to our users. Transwiser is a real legitimate business that bitshares users benefit greatly. To say that the Committee saved some speculators is simply a false statement.
The price feed flaw has been there all this while but it was not exposed publicly. The recent introduction of the 'Settle' button exposes the price feed flaw. Not surprisingly, the opportunistic flaw exploiters took advantage of it and gained unfairly at the expense of Transiwiser business, as well as other short players.
The 'Settle/Settlement' function has nothing much to do with the whole story.
