I assume Homrad just copied the answer that BitcoinAverage gave him, so he can probably only speculate to the meaning of it just like we can.
Bisq shows correct price from BitcoinAverage, why BitcoinAverage is so off, I have no clue.
Slack invite is fixed now. If you wish, you can take this discussion there, but other than switching from BitcoinAverage as a price provider, at least for the CAD market, I don’t think there is a lot we can do here.
