Greetings to Alt and the BTS community members,
Sorry for the late response to this situation and here is my explanation. On May 31st, bitcrab @ me in wechat group about the price feed issue and I responded immediately saying "I will check it" (see the figure below).
So I started to check my price feed script, which seems like the CNY to USD exchange rate caused the issue so I started to find more reliable API of currency exchange(I used the paid openexchangerates) and find if there is any logic bug can be fixed during the calculation of exchange rate. At the meanwhile, I was planning to add the premium between dex and external exchanges as a factor which is taken into consideration as a hotfix, to calculate the final price feed. However, when I first added the premium factor, I mistakenly messed up with its signs, but I found and fixed it immediately. So that's why there is a screenshot shows that the difference between my price feed and the median price feed reached 5%. In fact, this situation might not last for more than 10 minutes. You can see that bitcrab kindly reminded me about the issue at 13:47 and the screenshot about a 5% difference showed up around 14:00 when I am fixing. Finally, my price feed seemed like working well according to my observations later on that day(I am also constantly observing the price feed these days).
Since I thought that my price feed had been back to normal, I did not go to bitsharestalk to check if there was any new discussion about the price feed on the forum that day. And when I found this thread and prepared to respond, I found I cannot get the verification code to post unless *you know it* and due to the current network status(*you know it*), I failed a lot of times. Thus, I missed the in-time response to your question. I am extremely sorry for this and I promise that I will check the forum more frequently in the future. In fact, I really care about the price feed that I check it periodically and I also make quick responses to any changes decideded by the community consensus, e.g., MSSR.
This is my explanation about this event. I apologize for it again and I would be much appreciated if you can re-vote me again. Of course, any advice and suggestion from you and the community are thankful too. I will continue improving my price feed script. I hope we can make Bitshares much better.
