Can any of the frens understand this?

Using 100U margin for a full position long on OKB, the price is 162.26. The liquidation order price was at 152.27. The lowest price of OKB on that day was 156.31, which couldn't even reach the order price of 152.27. The platform actually liquidated me directly at a price of 156.89! Is this liquidation reasonable? This is 100U. If it were 10000U, I would have been liquidated with just a few thousand U left, which feels scarier than being robbed! I asked several customer service representatives, but none provided a reasonable explanation. In summary, this loss of 100U feels absurd. I rarely post messages on the platform, but this situation feels so unfair. When I have free time, I will post on various platforms to see if this is reasonable. I also hope that professionals in the crypto community can give me some guidance on whether it's my lack of experience or if the platform really made a mistake. Thank you 🙏
