Advanced order

So today I saw the stonks coin was about to be listed on KuCoin. The advanced order said to set a price which would act like a limit order. I set a price of 450, nothing appeared anywhere so I couldn’t see if the order was placed or cancel it. I later tried again with a limit of 400, same problem. Then when the coin was released, both triggered, at 400 and 450 when the coin was actually worth 350??? What kind of scam is that? Luckily I only locked small amounts and old right away, but it’s still a 40$ loss I would have liked to avoid.
