Open price = close price?

[TheImaginaryOne]

When I run

{
  poolDayDatas(where: {pool: "0x99ac8ca7087fa4a2a1fb6357269965a2014abc35"}) {
    open
    close
  }
}

the close price appears to be the same as the open price for all of the data. (The given pool address is just an example.) Is there a good reason for this to happen, or is it a bug?

This definitely appears to be a bug. You can see this as the close price for the day should be the open price for day - 1

{
pool(id: "0x7bea39867e4169dbe237d55c8242a8f2fcdcc387") {
    poolDayData(first: 2, orderBy: date, orderDirection: desc) {
      date
      open
      close
    }
  }
}

In concert with looking at the hourly data it appears that the close price is actually the open price Interestingly the hourly data seems to be correct so it can be used as a workaround

https://github.com/Uniswap/v3-subgraph/pull/102 There seems to be an attemp to fix it, but never gets reviewed/merged.

I'm running across this bug, as well (open and close are the same value).
