Token price in USD will changed when ETH price dump or pump?

If a token pair with ETH, You can check the chart on the Dextool or Dexsceen or whatever online chart site, But I have noticed, the token price only changed when the token buy and sell ETH price changed very frequently, But token price will not change if there is no swap operation on uniswap.::Listen

ETH price changed very frequently, But token price will not change if there is no swap operation on uniswap.

So how’s the dextool and others chart site works for display token price in USD?
