Thanks for finding the problem! Still, that must be a particularly unusual and bad outlier. I'll check the data later and will then get back to you.

Actually in crypto, this is nothing. If you want to see some crazy stuff, check out UNFIUSDT from the same date (not surprisingly also has this issue)

Yes. That's why the manual recommends to disable outlier correction for cryptos. But in this case, it turned out that the correction did not work at all. It can correct single spikes, but failed with particular sudden steps.

We'll modify that so that the correction wiill at least not produce those artifacts.
